The wall paper or other material 19, which is to be wound or rolled to form rolls of definite length, is suppliedin a continuous strip to the winding or roll forming rollers 23, 121,48. 4:9 and 35, which are so arranged about a centre as to leave a central space through which the end of the paper strip passes at the beginning of the operation. In this central space .a loop or told is formed in the paper strip to serve as a core for the roll, and in it the paper strip is wound on the core thus formed intothe roll desired.
Of these winding or roll forming rollers 23 and 121 arecarried on fixed axes and are po itively driven while rollz rsfifi, {t8 and 1.9,
also positively driven, are so mounted as to be movable outward away from the central space in which the roll is formed as the roll increases in diameter.
Directly above the roller 23 and so spaced from it as to permit the strip of paper to pass between its curved under surface and the periphery of roller 25) is guide 120 carried on arms 33 mounted to swing on shaft 29. In the rear of this guide 120 is a roller 22 mounted on shaft 22 journalled in arms 33 and so arranged with reference to roller 2 as to hold the paper strip between its periphery and the periphery of roller 23 so that the strip will be positively fed forward by the rotation of roller 23 into and through the central roll forming space about which rollers 23, 121. 48, 29, and 35 are grouped.
The paper strip 19 is guided to the feed rollers 22 and 23 by any convenient means, the means shown comprising roller 21, carried'by fixed shaft 21' and idler roller 20 carried on a shaft mounted in arms -11 which are pivoted at 42 in the frame of the machine, this idler roller serving to maintain suitable tension on the paper strip 19 as it comes from the source of supply. Roller 21 mounted on shaft 21 on which is secured gear 136 with which gear 131 mounted to rotate on stub shaft 135 is in mesh, gear 134 being also in mesh with gear 128.
AS the end of the paper strip is fed forward by rollers 23 and 22, it will be curved downward by the guide 120 and as it is fed forward it enters between guides 21 and 25 and strikes a stop 26. At the instant the end of the strip strikes stop 26 the portion near the end lies in a curved path following; between the forward end of guide 120 and the upper end of guides 24 and 25, or nearly following, the curve of the periphery of roller 23 (see Figure 8). Any tendency of the portion of the paper immediately above the stop 26 to be curved to the right, (see Figures 1 and 8 to 12) by roller 49 will be checked by the fixed guide 21 so that the paper cannot be curved except to the left and above roller 4-9. In this manner an initial downward curve or bight is formed in the end portion of the paper strip at a substantial distance from the end. As the feeding action of the feed rollers 22 and 23 continues the initial bend or bight is made sharper forming a loop, and is forced into contact with the periphery of rollers 121, and -18 (see Figure 12). These rollers act upon the curved portion or bi ght as the feeding forward by rollers 23 and 22 continues. to change the initial. curve into a fold, indicated at 15, Figure 1, and to force this fold over and downward against the upper surface of the paper strip (see Figure 13) and to draw upward the portion of the strip between the fold and the end which was in contact with stop 26 (see Figare 11) and to roll this end portion onto the loop thus forl'ning a core (see Figure 15) of double thickness on which the paper strip is rolled up by the action of the rollers 23, 121, 18, 49, and 35.
Roller 23 is carried by a stationary shaft 23 and is driven by a sprocket chain 23 and a sprocket on shaft; 12. (See Figure 1(5). This roller 23 serves a double purpose in that it acts with roller 22 to feed the paper strip and also acts as one of the group of roll forming rollers.
Roller 22 is carried by shaft 22' jonrnalled in arms 33, mounted to swing on rock shaft. 29. F ast on rock shaft 29 are arms 33 extending downward and to the right (see Fig ure 2) and in these arms 33 are journalled rollers 35 which cooperate with rollers 23, 121, 1:8, and 19 to form the paper roll These rollers 35 are in contact with and are driven by rubber roller 36 carried by arms 36 mounted to swing on shaft 29, and in driven contact with rollers 121 on shaft 12 which is driven by belt 10. By rotating rollers 35 through rollers 36 the direction of rotation of roller 35 is the same as the direction of rotation of roller 121. Also fast on rock shaft 29 is a depending arm 28 having at its lower end a roller 30 which bears against the tinted cam 31 on cam shaft 18 against which it is yieldingly held by the counter weight 32 secured to rock shaft 29.
The cam 31 acts through rock shaft 29 and arms 33 to press rollers 35 inward towards the centre of the central space between the roll forming rollers at; the beginning of the roll forming operation so as to aid in keeping the roll cylindrical until any tendency of its becoming oval is overcome. lVhen' the rolling has proceeded to the point when this tendency has been overcome; the cam permits the rock shaft to be rocked by the weight. 32 so as to swing arms 33 upward and to carry rollers out of contact with the roll.
Rollers 48 and -19 are mounted on shafts 48' and 1.9 respectively journalled in arms 46 carried by rock shaft: 17 on which is secured, outside side frame 1, an arm .50 by which, through mechanism hereinafter described, the arms 16 may be swung from the position indi :ated in full lines in Figure 7 to the position indicated in dotted lines to permit the roll formed by the forming rollers 23, 121, 48, 29 and 35 to drop out of this space and mto the space between rollers 77, 78, and 79, by which the forn'iing of the roll is completed. Roller 48 is rotated by means of gear 128 on driven shaft 12 which is in mesh with gear 129 loosely mounted on rock shaft 47 amlhaving secured to it gear 130 which is in mesh with gear 131 fast on shaft 18. Roller 49 is retated through the action of gear 131 on gear 132 loosely mounted on stub shaft 132 on arm 16, gear 132 being in mesh with gear 133 fast on shaft 49. By this arrangement rollers 48 and 19 are rotated continuously whether arm 46 is swung forward or rearward and are rotated in the same direction in which roller 121 is:driven. Arm 46 carries at its end bar 59 andistops 26 and above these stops the arm is preferably provided with guide between which andfixed guide 24 the end of the paper strip lies after the formed roll is As the rollincreases in diameter roll forming rollers 48 and 49 carried by arm 46 will be 1 gradually pushed backaand, as roller 49 is further from the shaft 47 on which arm 46 is pivoted, roller 49 will be moved away until it no longer in contact with the roll, and, roller having been moved away as above described, the rolling is completed by the if three rollcrs,23, 48, and 121.
, After the arm 46 carrying roll forming rollers 48 and 49 has swung. to the position indicated in Figure 7 in dotted lines and the roll formed by the group of forming rollers 23, 121, 48, 49, and 35has dropped into the space between formin rollers 7 7 78, and 79, as indicated at 104, t e strip or web is severed by knifeedgefiO of knife 27 which is carried by a arms 27 on rock shaft 61. The cuttingedge 6O acts with the bar 59 in cutting the dropped roll from the paper strip or web. The upper face ofthe knife 27 servesin the initial operation to guide the end of thepaper strip or web to stop 26. 5 a e The swing of arm 46 to the position shown in dotted lines in Figure 7 to permit the roll to drop is effected through the'action of a tappet arm 57 carried by cam shaft 18. As cam shaft 18 rotates this tappet arm strikes an offset 59 on a crank arm 55 mounted to swing on'stucl 56 and carrying upwardly ext-ending arm 54 to the upper 'end of which pivotally connected one endof link 53 the other end ofwvhich carried a pin- 52wwhich. extends into slot51 inarm 50. As the tap-- pct 57 strikes offset- 59 it forces crank arm 55 and lever 54 tothe le-ftyand through link 53and arm causes rock shaft 47 to rock to swing arm, 46. downward and to the left. A stop 144 on side frame 1 limits the swing of lever 50 towardsthe right and: so limitsthe swing of arm 46 and rollers 48 and 49 towards roller 23. i r i i a In the operation offorming 1the-roll1t- 1S necessary as the roll increases indiameter to permit forming rollers 48 and "49 to grad- This movement is controlled by spring 141,. one endwof which lSl00SlV connected to cam lially movefurtheroaway from roller 23.
shaft 18 and the other end of which is connecte'd to a pin 140on a lever 138, the lower 1 end of which, :is pivoted on stub shaft 137 on side frame 1. This lever 138 has a slide face 139 which acts against aslide block 142 pivot-ally mounted in "the forked end of an 1 arm 143 carried by rock shaft 47.
, As the roll being formed increases 'in diameter its of spring 141. The action of spring 141 to thus press the rollers 48 and49 against the roll may be supplemented by weights 145 adjustable on arms 145 carried by arm 50.
The-knife cutting edge 60 of the knife is preferably fluted as shown in Figure 6. The knife is carriedby arms 27 on rock shaft 61. 'A weighted segment 62 depends from one end of shaft 61 on which it is loosely carried. On this segment- 62 is a pincarrying roller 63 which is in the path of a tappet arm 64 on camshaft 18. The segment 62 is also provided with a finger 64" which as the segment isrocked by the tappet arm 64 striking roller 63. strikes depending arm 63 of a bell crank lever fast on shaft 61, the upper arm 74 of which is connected by. link 73 and pin 72 to depending arm 71.0f a segment shaped weight 69, pivoted at above shaft 61. A spring 73. is secured at one end to the frame of the machine and at :the other end to link 73. a As the arm 64 is carried around on cam shaft 18 in the direction indicated by arrows in Figure 3, its endstrikes roller 63 and rocks segment 62 upward bringing its finger 64 against the depending arm 63 of the bell crank lever and rocks knife 27 to the position indicated in dotted lines in Figure 7, that is, away from stop 26. At the same time the upperarm 74 of y the bell crank lever raises the lower end of link 73 and permits spring 7 3 to draw-the ,upper end of this link73 to the left swinging thelower end of arm 71 leftward and permitting weighted segment 69 to drop. The parts are. temporarily held in this position by the engagement of the 'upper end of i a stop arm 65 pivoted at 66, this upper end .beingin the path'of the depending arm 63 of the bell crank lever so that asthe end of this depending arm passes the end of 65' it moves it to the left againstthe force of spring 67 and this upperend of 65" is at once swung by the spring beneath the end of arm 63'. Spring 67 is connected at one endto the stop arm and attheother end to a pin 68 on the frame of the machine. ,At the arm 64' is vcarried further around it strikes a block 76 at. the base of stop arm 65 causing the upperend of the stop arm to swing to the left to release arm 63'. This releases rock shaft 61 and permits it to be rocked in a direction to carrytheknife 27 against the paper strip to cut it off by action of its edge 60 with counterbar 59. This cutting action is effected by spring .116 connected at one end to arm 1 17 on rock shaft 61 and connected at the other end to the frameof the machine.
The roll formed by the upper group of forming rollers having been allowed to drop by the outward swing of arm 46 drops into shaft 61 in a direction to swing wit the space between lower forming rollers 77 and 79 onto roller 78. as indicated at 101, and the paper is severed by the knife. Roller 79 is carried on fixed shaft 81 on which is mounted sprocket which is rotated by sprocket chain 82 which is itself driven by sprocket 83 on drive shaft 8. Roller 78 is carried by shaft 8. having its bearings in the upper ends of arms 92 which are secured at their lower ends to rock shaft 93. On shaft 84 is mounted sprocket 85 driven by sprocket chain 80 which. extends about sprocket 88 on drive shaft 8 and idler sprockets 87 and 89 so that roller 78 may be moved towards and away from roller 79 and still be positively driven. Idler sprocket 87 is carried by weighted arm 90' pivoted to the frame at 91. the weight of arm 90 keeping the sprocket chain 86 under tension.
On shaft 93 is loosely mounted an arm 90 carrying at its free end a roller 9 1 which bears against a cam 95 on cam shaft 18. Above the roller 94 a toe 96 is formed on arm 96 adapted to be engaged by a hook 97 which is fast on a stub shaft 103 which has a bearing in the side frame 1 and has secured to it an arm carrying a roller 99 on pin 99 so placed that as the arm (it on cam shaft 18 1'0- tates it strikes roller 99 and swings the left end of lever 100 downward retracting hook 97 and releasing toe 96 of arm 90 to permit arm 92 to swing outward and move roller 78 and 77 away from roller 79.
The arm 92 may be adjusted relative to arm 96 bv a hand operated screw 125 to allow for difference in diameter of the roll due to difference in thickness of the paper.
Roller 77 is carried on a shaft having its bearin gs in the upper ends of arms 7 7 loosely mounted on shaft 8-1, one of these arms 77 being extended downward below shaft 8 1 and to the end of this extension is secured one end of a spring 127. the other end of which is secured to arm 92. The roller 77 thus moves toward and from roller 79 with roller 78 but is capable of yielding against. the force of spring 127 independently of roller 78 so as to permit the roll of paper as it drops from the upper group of forming rollers to press roller 77 outward suiliciently to permit the roll to enter. the space between rollers 78 and 7 9, roller 77 being at once moved inward by spring 127 to press against the roll at a point above the horizontal plane of its centre. Rollers 78 and 79 being positively driven the end of the strip between the roll and the knife 27 is quickly wound onto the roll.
lVhen the hook 97 is released as above described and the arm 92 drops back to carry the rollers 77 and 78 away from roller 7 9, the roll now completed, drops onto the previously completed and dropped roll resting on the endless chain conveyor 106, against the inclined arms 150, and 151. which extend upward and to the right below the upper portion of the conveyor 106. The drop of the roll is then continued by the roll last completed. At the same time the dropped roll acts upon the roll onto which it drops to cause it to move to the left to make room for the dropped roll. Each completed roll as it drops from the second group of roll forming rollers thus takes its place at the lower end of the incline up which the rolls are moved by the endless chain to its left hand or delivery end. At either side of the lower right hand end, side pieces 107 and 108 are provided (see Figure connected by rods 109 to the lower ends of levers 110 which are pivoted at 111 to a rod 112, supported at its ends in the side frames 1 and 2 and are each provided at its upper end with a roller 113. the two rollers being in the path of a two sided ram 114 fast on cam shaft 18 so that at each rotation of the cam shaft the cam 111- forces the upper ends of levers 110 apart and forces their lower ends through rods 109 to draw side pieces 107 and 108 towards each other. The side pieces being thus forced towards each other act against the ends of the roll of paper to bring its ends into proper alignment and to square up the ends of each roll so that as the roll is carried away by the conveyor its ends will be in line with the ends of preceding rolls. Any tendency of the paper to unroll is counteracted by the movement of the conveyor chain and the resistance of the roll to the movement up the incline, the rolls being thus caused to rotate in the direction required to wind the end of the paper onto the roll.
In order to facilitate the introduction of the end of the strip or web into thespace between the rollers of the upper group of forming rollers and to facilitate removal of paper which may have become jammed the right hand end of one of the arms 33 carrying roller 22 and guide 120 is connected by rod 40 to the end of lever 39 pivoted at 38 near the base of the machine and provided with pedal 37. By pressing ones foot on this pedal the arm 33 is swung upward to leave a substantial space between rollers 22 and 23 to give access to the mechanism.
To aid in introducing the end of the paper strip or web from which the rolls are to be formed are shaped arms 43 are provided pivoted at 4-4 near the front edge of the machine frame at such distance from the roller 23 that the ends of these arms 43 will, when the arms are swung downward, enter the space between the peripheries of rollers 22 and 23 and may carry the paper strip or web with them into this space.
In introducing the paper strip or web its end is passed under idler 20 over roller 21 and allowed to fall down onto table 44'. Its end may be readily torn off on the outer, right band edge of 44 in order to get the edge at right angles to the sides. By then swinging the arms 43 downward the edge of this arm Inn side frame of the machine and of arms 33 one is used for each roller 35.
The rollers 121 are shown fluted but the fluting may be dispensed with. As many of these rollers and of rollers48, 49 and 35 as may be desired may be used, the rollers on their shafts 12, 48"and 49' being so spaced,
as indicated in Figure 4, that they do not conflict with one another.
