FOLD PLATE FOR FOLDING MACHINES Filed Aug. 4, 1944 INVENTOR.
Ala/F7119 Patented Jan. 14, 1947 amass UNITED STATES PATENT OFFICE 7 Claims.
This invention relates to a folding machine and more particularly to a fold plate for a folding machine of the buckl type. In the buckle type of folding machine the sheet of material to be folded is inserted between two rolls which move the end portions of the sheet into a fold plate, which comprises upper and lower members spaced apart to receive the end portion of the sheet between them and is provided with a stop to limit the movement of the sheet. When the end of the sheet engages the stop the continued movement of the rear portion of the sheet by the rolls causes an intermediate portion of the sheet to buckle toward and to enter the bite between one of said rolls and a third roll which complete and crease the fold. When more than one fold is to be made in the sheet the last mentioned rolls move the folded sheet into a second fold plat and cause the same to again buckle between the third roll and a fourth roll, this folding operation being repeated for each additional fold. It is important that the sheet shall be supported by the fold plate substantially in a true plane, that there shall be no binding or unequal resistance to the movement of the sheet and that the stops, of which there are usually two, shall be of such a character that there is no possibility of the edges of the sheet extending between the stop and One member of the plate so as to wedge therein or to inaccurately position the sheet.
Heretofore it has been customary to provide both the upper and lower members of the fold plate with slots extending in the direction of movement of the sheet and to mount the stops on the outer side of one member, each stop extending through a slot in the adjacent member and into the corresponding slot on the other member. The slots extend for the major portion of the length of the plate, to permit a wide range of adjustment of the stops, and are of such width that the sheet tends to sag into the slots in the lower member of the plate. This sagging of the sheet often distorts the same in such a manner as to cause wrinkles to be formed therein as it passes between the folding rolls. If one lateral portion of the sheet sags to a greater extent than the other lateral portion thereof increased resistance is offered to movement of those portions of the sheet which have entered the slots and this may so displace the sheet that the fold line will be improperly formed. The slotting of the lower member of the fold plate is very apt to distort the same and it is diflicult, if not impossible, to thereafter straighten the distorted member So as to provide the same with a plane sheet supporting surface. Any unevenness in the supporting surface results in binding or in more resistance being offered to the movement of certain portions of the sheet than is offered, to other portions and this may so displace the sheet that the fold line will not be perly formed. Further, the lower member of the fold plate usually formed of relatively thin sheet metal and the slotting thereof requires the use of expensive dies, so that the cost of a slotted member much greater than the cost of an unslotted member.
Qne object of the invention is to provide a fold plate which will support the sheet in a flat condition and will offer uniform resistance to the movement of all parts thereof.
A further object of the invention is to provide a fold plate the lower member of which has a continuous sheet supporting surface arranged substantially in a true plane.
A further object of the invention is to provide a foldplate in whichthe stops rest upon the supporting surface of the lower member and have such contact therewith as to prevent the edge of the sheet extending between the stop and the supporting surface.
A further object of the invention is to provide a fold plate with a stop which can be quickly and easily moved from one transverse position to another transverse position without afiecting the adjustment thereof lengthwise of the fold plate.
A further object of the invention is to provide such a fold plate which is simple in construction which can be manufactured at a relatively low cost.
Other objects of the invention may appear as thedevice is described in detail.
In the accompanying drawing Fig. l is a plan View, partly broken away, of a fold plate embodying my invention; Fig. 2 is a section taken on the line 22 of Fig. 1 with the fold plate supported in operative relation to the folding rolls; and. Fig. 3 is a detail of one of the showing its relation to the two members of the fold plate.
In this drawing I have illustrated one embodiment of my invention and have shown the same in associat on with a set of folding rolls of standard. arrangement. It is to be understood, however, that the invention may take various forms and may be used with folding devices of any suitable character.
In the embodiment here illustrated the fold plate comprises an upper member or top plate 5 substantially rectangular in form and provided with a plurality of slots 6 extending lengthwise thereof, that is in the direction of movement of the sheet, for the major portion of the length of the member. Preferably the slots terminate short of the ends of the member so that both end portions thereof are continuous for the full width of the member, and the member is of suflicient thickness to impart rigidity to the fold plate as The lower member or bottom plate I is rigidly secured to the upper member and is spaced from the lower surface of the upper member to provide a guideway in which the sheet to be folded may have free movement. ,This lower member is of substantially the same size and shape as the upper member but is of less thickness, it preferably being formed of thin sheet.
material. The lower member, or at least the sheet supporting upper surface thereof, is continuous throughout its area and the supporting surface is substantially in a true plane, so that it supports the sheet in a true plane and offers equal resistance to the movement of all parts of the sheet supported thereon. It may be secured to the upper member in any suitable manner, as by bolts 8, extending through both members and through spacers arranged between the two members adjacent the edge portions thereof.
' There may be any suitable number number of stops but usually two are employed and in the present instance these stops are of such a character that they may be supported on the upper member and will have firm contact with the supporting surface of the lower member. Preferably each stop is so supported that it can be adjusted both transversely and lengthwise of the fold plate. In the arrangement shown each stop 9 is mounted on a rod ill which extends transversely to and above the upper member. The stop has an enlarged portion II to receive the rod l8 and a downwardly extending portion i2 is adapted to rest upon the lower portion of the member I. The lower end of the stop is slightly beveled as shown at It, to provide the same with a relatively narrow contact edge at that face thereof adjacent the sheet, so that when the stop rests upon the lower member there will be no possibility of the edge of the sheet being moved between the stop and the lower member, thereby preventing any wedging or binding of the sheet under the stop. The stop is mounted on the rod for pivotal movement about the same and for movement lengthwise of the rod, that is, transversely to the slots. Thus by first moving the stop about the axis of the rod it can be moved lengthwise of the latter into a position above a selected slot. This enables the two stops to be quickly and easily adjusted with relation to the width of the sheet which is to be folded. Each stop is preferably so mounted that it will be moved by gravity into engagement with the supporting surface of the lower plate and held in firm contact therewith, although if desired the stops may be spring actuated. To increase the gravitational action and to maintain a firm pressure of the stop on the supporting surface each stop is here shown as provided with an upper portion, l2a, which extends some distance above the rod Ill and is so arranged that when the stop is in operative position" it will be inclined forwardly and this upwardly extending portion will materiallyincrease the pressure thereof on the supporting surface.
To enable the stops to be adjusted lengthwise of the fold plate, to determine the position of, the
fold, the rod Ill is supported at its ends in blocks M which are slidably mounted upon rods 15 extending lengthwise of the fold plate adjacent the respective lateral edges thereof. Each block is provided with a set screw It by which it may be secured in adjusted positions and the fold plate is provided with a gage or gages l1, extending lengthwise thereof to facilitate the accurate adjustment. of the rod Ill ,and the. stops 9, there being preferably two ofthese gagesarranged adjacent the respective sides of the fold plate. In this manner a fairly accurate adjustment of the stops can be quickly effected by loosening the slide blocks [4 and moving them substantially to correct positions but to enable fine adjustments to be made the longitudinal rods l 5 are mounted for longitudinal adjustment and, as here shown, these rods are mounted in bearing blocks l8 at that end of the fold plate toward which the sheet moves, these bearing blocks being in the present instance rigidly mounted on the upper member of the fold plate.
blocks are screw threaded and knurled nuts H! are mounted thereon and bear against the respective blocks I8 to effect the fine adjustments of the rods. Preferably those portions of the rods which extend through the blocks l8 are of reduced diameter to form shoulders 20 on the blocks and compression springs 2| are confined between the shoulder 29 and the adjacent faces of the blocks l8 and thus yieldably hold the nuts 19 in contact with the respective blocks H3.
The fold plate is usually mounted in an inclined position, preferably at an angle of approximately 45 degrees, with the lower ends of the plates in proper relation to a set of folding rolls. As shown in Fig. 2, there are three parallel rolls, the upper roll 22 rotating about a fixed axis, the roll 23 being arranged directly beneath the roll 22 and having yieldable contact with the latter, and the roll 24 being arranged on that side of the roll 23 adjacent the fold plate and having yielding contact with the roll 23. The sheet 25, of paper or other material, is interposed between the rolls 22 and 23 and the forward portion thereof enters the space between the two members of the fold plate,
the end portion of the upper member 5 having a rounded lower surface 25 to guide the end of the sheet between the two members of the plate.
When the forward edge of the sheet contacts the stops I2 the further movement of the rear portion of the sheet by the rolls 22 and 23 causes the web to buckle adjacent the lower end' of the fold plate, as shown at 2?, this buckling being toward the bite of the rolls 23 and 24 so that the buckled portion extends between these rolls and is gripped thereby to complete the fold, the fold being creased as it moves between the rolls. The rolls 23 and 25 may discharge the folded sheet if a single fold is to be made therein, or, if an additional fold is to be made, the sheet may be delivered by the rol1s'23 and 2 to a second folding unit.
tion that I have provided a fold plate in which the sheet supporting surface of .the lower member-is continuous and in a substantially true plane so that the sheet will be supported in substantially a true plane and the. resistance offered to the forward movement thereof will be uniform through- Those ends of the rods which extend through the respective bearing It willbe apparent from the foregoing descriperably by gravity, although springs may be used if desired. The mounting of the stops is such that they can be quickly and easily adjusted transversely of the fold plate without afiecting their longitudinal adjustment and may be adjusted lengthwise of the plate quickly and easily and to very exactly determined positions. The unit as a whole is simple in its construction and can be produced at a low cost.
