Garrison Ave., Carthage, Mo. 64836) Filed Oct. 14, 1965, Ser. No. 496,033 9 Claims. (Cl. 270-79) ABSTRACT OF THE DISCLOSURE A machine for rapidly producing zigzag folds in an elongated strip of paper and discharging a multifold prod not with folds in overlapped relation. The machine feeds the strip toward a table to loop the strip alternately in opposite directions between stops spaced along the table, there being rollers cooperating with the stops to flatten the loops into sharp folds.
The invention relates to a machine for zigzag folding of a continuous strip of material as supplied usually from a roll of paper.
The main object of the invention is to expedite the flat and accurate folding of the material in the strip by thrusting alternate loops of the folds against spaced opposing stops and simultaneously subjecting the individual loops to creasing compression by impacts from coacting machine elements as distinguished from folding machines previously made in which successive folds are fed against stops by friction elements and are subject to creasing pressure mainly as the folds increase substantially in number.
This general object is attained by feeding looped areas of the strip against a stop and simultaneously sharply pressing the sides of each fold toward each other. Preferably the mechanism includes a surface for supporting the paper as it is folded back and forth, spaced apart stops above the supported surface, spaced apart belts and cylinders extending transversely of the supporting surface for feeding the strip toward the stops alternately, the stripengaging portions of the stops and cylinders being grooved and ridged to enable the rollers to rapidly and sharply impact and compress the strip loop during its folding by the machine.
These and other specific objects are attained by the machine shown in the accompanying drawings illustrating a selected embodiment of the invention, in which:
FIG. 1 is a perspective of the machine.
FIG. 2 is a top view of the machine.
FIG. 3 is a longitudinal vertical section on line 3--3 of FIG. 1.
FIG. 4 is a transverse vertical section of the machine approximately on line 44 of FIG. 3.
FIGS. 5 and 6 are detail sections showing successive positions of the paper contacting elements of the machine during the completion of a fol The machine includes a substantially rigid frame having a front side 1, where the operator is stationed normally, a rear side 2, an input end 3 and an output end 4. Brackets on the input end mount a spindle 10a which carries a roll of paper R. The paper in the roll has been perforated or scored previously transversely of its length at regular intervals and the flmction of the machine is to flatten successive folds or loops facing in opposite directions along the transverse lines of perforations or scorings P.
A table 5 is mounted on frame 1 and extends substantially the full length of the frame and projects at 6 to Patented Nov. 14, 1967 the left of the frame. Transverse rollers 8, 9 at the ends of table 5, 6, and transverse bars 7 between rollers 8, 9 mount conveyor tapes 11 which run lengthwise of the table and feed the folds F, formed in paper strip S, along extension 6 for manual removal from the machine.
Paper strip S from roll R is led over a feed roller 13 having a shaft journaled in the sides of the machine frame. A hold-down roller 14 is journaled on the swinging ends of arms 15 pivoted on a spindle 16 seated in brackets 17 on the sides of frame 1. A rod 18 extends to the left from spindle 16 and a weight 19 slidable along rod 18 provides for adjustment of the friction between rollers 13, 14 and the paper strip. Roller 13 'is driven by a belt from a motor M mounted on a transverse frame platform L.
Transverse feed belt rollers 20 include shafts journaled in the sides of the machine frame intermediate the ends of the frame and are belt driven from roller 13, the shafts of rollers 13 and 20 being geared to each other. Flat bars 22, 23 (FIGS. 3, 4) are disposed end to end lengthwise of the machine and have their adjacent ends pivoted on the shafts of rollers 20, 20, respectively. The-opposite end portions of bars 22, 23 slidably mount bearings 24 for the shafts of idler belt rollers 25. Bearings 24 are adjustable along bars 22, 23 by screws 24a. A plurality of V-belts 26 are seated in grooves in rollers 20, 25.
Intermediate each roller 20 and associated roller 25 is a short channel section bearing block 27 (FIG. 4) slidable along the bar 22, 23 but retained at desired position as explained below. Each pair of blocks 27 at front and rear of the machine journals a shaft 28 mounting a cylinder 29 each having a plurality of spaced rows of teeth 29a and the grooves between the rows of teeth receive the lower flights of belts 26 and drive the cylinders in the direction of arrows A. Beneath each cylinder 29 is an angle stop 30 extending transversely of the machine and secured at its ends to bars 22, 23 respectively and having its upright leg notched at N (FIGS. 5, 6) to receive the cylinder teeth. The horizontal leg of each angle stop is spaced above tapes 11 and table 5 but this space may be adjusted as explained below.
As the paper strip is fed downwardly by roller 13 it contacts belts 26 and is moved toward tapes 11 and doubles along the perforation lines P to assume oval loop forms beneath the lower flights of the belts. As the paper strip begins to loop, the upper leaf of each loop is engaged by the lower flights of the V-belts and is frictionally moved toward a corresponding stop 30. Then successive teeth 29a contact the end portions of the loops and press them downwardly from the belt and toward the stops. As successive loops accumulate, the teeth press the loops closer to the tapes and table and reduce the height of the loops and crease their folds more sharply. As the folds accumulate between belts 26 and tapes 11, sufficient friction'is created to cause the tapes to move a group of the folded sheets to the left from beneath the cylinders and the friction-induced movement carries the foldsto spacing of these parts according to the thickness and stiffness of the paper strip. It is to be understood that the most effective action will result from a careful coordination of the tape speed, tautness of the belts and tapes, the distances between the belts and tapes and between the opposed stops, the distances between the cylinders, their stops, and the table and tapes, all varying with the thickness and stiffness of the paper and with the Width and length of the folded loops. Such adjustments are readily effected, as described below, by an attendant stationed at the front of the machine The ends of the bars remote from rollers 20 are supported by individual transverse carriers 31 (FIGS. 1, 3), the ends of which are slidable vertically along brackets 32 on the machine frame. An upstanding threaded shaft 34 is attached at its lower end to the middle portion of each carrier 31 and extends upwardly therefrom through a horizontal bar 35 supported on brackets 32. A hand wheel 36 threaded on each shaft 34 supports that shaft and associated carrier 31 and provides means for readily adjusting the height of the outer ends of the associated pair of bars 22, 23.
Each bar 22, 23 is provided with an adjustable extension 40 which includes a bearing for a transverse shaft 41. Journaled in each pair of bars 22, 23 and associated shaft 41 are a pair of spaced sprockets 43, 44 which mount an endless sprocket chain 45 engaged by a finger 46 depending from bearing block 27. The shaft of each sprocket 44 is rotatable by a hand wheel 47 at the front of the machine. Thus the associated front and rear chains 45 and bearing blocks 27 for a cylinder 29 are moved simultaneously by the attendant without leaving the front of the machine. Each block 27 has a lock screw 48 for clamping the adjusted block to its supporting bar 22, 23.
Also the table is raised and lowered by upright threaded shafts 56 threaded through table supporting carriers 57 and having lower end bearings 58 on end pieces of the machine frame. Sprockets 59 on the upper ends of shafts 56 at front and rear of the machine are connected by chains 60. A hand wheel 61 on the front shaft 56 only of each pair of shafts provides for simultaneous and equal raising and lowering of the front and rear ends of each carrier 57 and of the corresponding end of the table.
Tapes 11 are moved along table intermittently by the overriding clutch 71 (FIG. 1) oscillated by a lever 72 connected by a block 73 positioned along lever 72 by a screw 74 rotatable by a hand wheel 75 and connected by a pitman 76 to an adjustable eccentric pin 77 on a drum 78 at the end of a shaft 79 driven by a chain 80 (FIG. 2) and a sprocket 81 on a shaft 82 geared to the shaft of feed roller 13. Hand wheel 75 facilitates ready variation of the extent of the step-by-step advancement of the tapes. 7
A tape elevating roller 85 (FIG. 3) is mounted on the free ends of crank arms 86 on a shaft 87 journaled in the machine frame and manually adjustable by a worm wheel 88 and handle 89 (FIG. 1). This device facilitates vertical adjustment of tapes 11 immediately beneath the right hand angle stop 30. Similar adjustment is not required beneath the other stop as the movement of the tapes, indicated by arrow B, delivers the folds to the left as shown in FIG. 1.
All the critical adjustments are identical at front and rear of the machine and are readily effected by the attendant operating a single control 'for each adjustment. The adjustments may be made while the machine is operating and throughout the range of machine speeds and while the paper folding is in full view of the attendant. This greatly reduces the set-up time as well as making possible high speed production operation.
The details of the structure may be varied widely in details without departing from the spirit of the invention and exclusive use of modifications embodying the spirit of the claims is contemplated.
