Patented June 2, 1936 UNITED STATES PATENT O F CE WEB ROLL CONTROLLING Application March 13, 1933 Serial No. 660,470

' Renewed November 1, 1935 This invention relates to the controlling of the e h and unn ng r ll a w splicing device e pr n n ma hines a d h like! he Princ al o e i thi invention are to 5 provide means for controlling the fresh and running rolls at about the time of splicing, having provisions for insuring that the controlling means shall have released control of the running roll not later than the time at which it assumes 1 control, of th fre h. r l and i Prov means for securing an. amount of wrap am ne the running or fresh roll as may be desired.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying d awi s in hi h he .1. cnsl i w of a ref rr d embodiment of this invention in which it is applied to a W611 known t p r ll supp rtin I66 and a 20 movable brush for forcing the web against the surface of the fresh rollat the time of pasting;

Fig. 2 is a similar View showing a modification in which a roll instead of a brush is used for pasting;

25 Fig. 3 is a diagrammatic view similar to Fig. 1 showing the next position in which the running roll is partially used up and means has been provided for wrapping the propelling belts part way around the running roll;

30 Fig. 4 is a similar view in which the running roll is reduced substantially to its smallest size ready for pasting and the propelling belt or belts have moved out of contact with the running roll but have not come into contact with the fresh 35 roll;

Fig. 5 is a similar view showing the reel turned practically to pasting position and the fresh roll in contact with the belt or belts to bring it up to web speed and. the belts wrapped part way 40 around this roll;

Fig. 6 shows the parts in a position with the reel rotated still further and the splicing action taking place;

Fig. 7 is a similar view showing the splicing 45 action completed and the web being severed, and

Fig. 8 is a similar view showing the reel with the new roll now acting as the running roll, the cycle of splicing having been completed.

The invention is shown in Fig. 1 in a form in 50 which pedestals I provide a support for a rotatable shaft 2 on which are carried spiders 3 constituting the reel. This reel is rotated by any well known means fully under the control of the operator and is turned in the instance shown,

55 in a counter-clockwise direction. It carries a (01. egg-58 fresh roll 4 and a running roll 5 which, as usual, are rotatably mounted between the spiders. The Web W passes over bending rolls 6 and! to the press.

A web pressing means in the form of a brush 8 is shown attached to a bracket 9, which is secured to the framework of the press. An arm I0 is shown as oscillatably mounted on the two brackets 9, one on each side of the press, and carries a knife I l adapted to be used to sever the 10 old web after a splice has been completed.

Brackets l2, one on each side of the press, form a stationary support for a drive shaft l3 which may be driven from any source of power, but preferably it is driven by a shaft of the press. A series of pulleys [4 on the shaft l3 drive one or more belts 15 at practically web speed. Each belt is provided with a loop in which is a pulley l6 carrying a yoke I7 and a weight l8 for keeping the belts taut and providing tension. It also passes over a movable pulley l9 and idlers 20. Arms 22 at each side of the press are pivotally mounted on the brackets I2 and they'carry a shaft 23 on which the pulleys l9 are mounted. A link 24 connects each arm 22 with a bell crank 25 25 which is secured to a shaft 21 pivoted on the brackets [2. The other arm of this bell crank carries a poppet 26 which is threadedly connected with an operating rod 28. Another poppet 29 connected with the bracket I2 and adjusted on 30 the rod by collars 39 is provided to fix the operating rod longitudinally. A hand wheel 3| fixed to the end of the rod provides means by which the rod may be rotated to swing the bell crank 25 in either direction, as desired, thereby changing the position of the movable pulleys l9.

In the form shown in Fig. 2 everything is in tended to operate in the same way except that a pasting roll 32 is provided in slidable brackets 33 pushed toward the roll by springs 34. These brackets are limited in motion by studs 35 operating in the slots of a support 36 which is secured to the framework of the press.

It will be understood that, as far as the splicing is concerned, this is accomplished in the usual way by the brush 8 or the roll 32, as will appear later. The so-called splicing device is pressed against the web to cause the web to pick up the prepasted points on the fresh web roll to make the splice.

Referring to Figs. 1 and 3 to 8 inclusive, it will be seen that the running roll 5 is located above the fresh roll 4 and in Figs. 1, 3, 4 and 5 is feeding the web to the press. Fig. 1 shows the parts in the normal running position and Fig. 3 shows the first action for splicing. Here the hand wheel 3| has been moved so as to project the rolls l9 toward the reel and wrap the belts slightly around the surface of the roll to give more surface for holding back thisroll when its diameter gets small. In Fig. 4 the roll 5 has become so small that it no longer touches the belt or belts; The reel is in the same position as in Figs. 1 and 3, but pulleys [9 are adjusted away from the reel so that the running roll 5 is out of contact with the belts l5 before fresh roll 4 contacts, thereby insuring no disturbance of the prepasted points on the fresh roll by belt slapping induced by the running roll.

The next step is to turn the reel so that the roll 5 moves over to the left and the fresh roll 4 moves up into contact with the belts. The pulleys I9 are then moved forward and get as much control of the new roll as possible to rotate it up to web speed by means of the belts. While this is being done the reel is moved until brush 8, or roll 32, presses the web against the fresh roll as shown in Fig. 6 and the web is severed as shown in Fig. 7; This completes the splicing operation and'the press is fed from the new roll 4 as shown in Fig. 8 with the pulleys still advanced to increase the length of the surface of the new running roll 4 which is engaged by the belts.

It will be seen that one or more flexible members in the form of running belts is shown for accomplishing these objects and that it is insured that the running roll is out of contact with them before or at the same time that the fresh roll contacts with them. In this way less disturbance is caused with respect to the fresh roll, thereby minimizing the likelihood of disarranging the prepared leading edge of the fresh roll. It will be understood that some light means is used for holding down the leading edge before the time of splicing and that spaces are left against which thebelt or belts may operate to speed up the fresh roll without contacting with the fresh paste.

1 of a reel for supporting a running roll and a Although I have illustrated and described only two forms of the invention I am aware of the fact that other modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in 5 the claims. Therefore, I do not wish to be limited in this respect otherwise than as set forth in the claims, but what I do claim is:-

1. In a web splicing device, the combination fresh roll, a movable means connected with the press to which the web from the running roll is delivered, to be operated substantially at web speed, the running roll being located above the fresh roll and normally contacting with said means, said movable means being so located with respect to the reel that the running roll, located at the time in a fixed position, will move out of contact with it by reduction in sizebefore the reel is turned to bring the fresh roll into contact with said movable means. 7 p

2. In a device for controlling and speeding up web rolls for a. web splicing mechanism, the combination of an endless belt for engaging the surfaces of said rolls, means for guiding the belt located in a position near the Web roll which the belt is engaging, and means for moving said belt guiding means toward both rolls to cause a wrap of the belt around an arc of the circumference of the web roll located nearest to said guiding means.

3. In a device for controlling and speeding up web rolls for a web splicing mechanism, the combination with an endless belt for engaging the surfaces of said rolls, of a roll for guiding the belt located in a position near the web roll which the belt is engaging, and manually controlled means for moving said belt guiding means toward said roll to cause a wrap of thebelt around an arc of the circumference of said web roll.
