17 Claims.

The invention relates to a web trimming and splicing machine for use in cutting or trimming and splicing the waste ends of paper rolls used in printing newspapers or the like in order that these may be formed into a single continuous web, adapted for use in printing after the manner of the respective webs from which the waste ends are obtained. While the machine is particularly adapted for use in this way and has been devised for this purpose, it is also adapted for use in joining the waste ends of other webs used for other purposes, of paper and other materials. By the use of this machine an important economy is effected which is very large in its proportion to the cost of the installation.

In the accompanying drawings, we have illustrated a machine embodying the invention in the preferred form, the design of the machine as to numerous details being subject to variation within the broader scope of the invention.

In the drawings:

Figure 1 is a top plan view of the machine with the cutter carriage removed.

Figure 2 is a side elevation of the machine with the web in the position which it assumes after splicing, the splice having moved forward in the direction of rolling the combined web onto the take up roll.

Figure 3 is a section through the table on the line 3-3 in Figure 1, showing the cutter carriage and other parts and also the web ends in the position which they assume in the cutting operation. This view is on a relatively enlarged scale.

Figure 4 is a view looking from the right in Figure 3 showing the web in section on the line 44 in said figure, the table, the eccentric shaft and other members running across the machine being shown fragmentarily in elevation, the view being on the scale of Figure 3.

Referring to the drawings by numerals, each of which is used to indicate the same or similar parts in the different figures, the machine as shown comprises a cutter carriage l, a frame 2, having at one end supporting bearings 3 for the waste end roll or let off shaft 3 for the waste end roll 3 and at the other end, bearings 4 for the take up shaft 4 to which are secured the rolls 4 which carry the product in the form of a continuous spliced web 400. The frame 2 also carries intermediately of the roll bearings 3 and 4, a transversely extending relatively elevated table 5 to which the stationary cutter 6 is secured and on which the swinging cutter bar 1 is mounted. The frame 2 comprises side frames 8 at each side of the machine on which the table 5 is mounted at its ends in vertical guides 9. The table 5 is supported on a plurality of eccentrics IE! which are secured to the transverse shaft ll shown in section in Figure 3, the table being in turn provided with depending guide plates i2 5 which are slotted vertically at [4 to provide for motion of the table relatively to the shaft and to assist in guiding the table. The eccentrics are operated to raise the table when desired as hereinafter described, by means of a hand crank 10 I5. The upper position of the table 5 and the eccentric Iii are shown in full lines in Figure 3, the low-er position of each being shown in dotted lines.

The cutter 6 extends across the machine from side to side and is provided with a cutting edge at 6' which cutting edge is preferably undercut as shown for convenience in grinding and to provide a single contact at the edge. The undercut arrangement shown prevents deflection of the moving cutter out of contact with the edge 6' in case the cutting edge should be ground back beyond the plane of the main body of the cutter below the cutting edge. In accordance with the construction shown, the cutting edge extends across the machine at right angles or substantially at right angles to the direction of feed being curved at its ends away from the plane of cutting as shown at 6" in Figure 1 to guide and admit the cutter I8. 30

Opposed to the cutter 6 is a cutting plate "5, see Figures 2 and 3. This is spaced backwardly from the cutting edge 6' toward the let off or waste end roll 3 to provide a cutting slot I! for the entrance of the moving cutter or knife [8. At its lateral ends, the front edge l6 of this plate I 5 is curved backwardly at I!) to locate and admit the moving cutter or knife l8 to be further described, as it enters the slot and approaches the locality of cutting. The side ends of this slot H are indicated at H.

The cutting bar 1 in the form of the invention shown, is mounted on the frame to rest with its full weight on the web which is supported on the table. The cutting bar as shown is connected to the frame and guided by hand levers 20 which are pivotally mounted at one end on brackets 2| secured to the side frames 8 at each side of the machine so that it can be swung upwardly from the table. This cutting bar 1 extends from one lever '20 on one side frame across the machine, being secured at its ends to each said lever 20 intermediately of the length of said lever 20, in any suitable manner, as by means of screws 20. At their opposite ends from the brackets 21, the

levers 29 are provided with handles 22 by which they are operated. When the table is lowered as described, the levers 25 contact stops 2i on brackets 2! whereby the bar I? is suspended above the table. The rear side of the cutting bar 3, as shown, the feed and take up being to the left in Figure 3, is grooved longitudinally at 25, said grove being referred to as a clamping groove, and the bar l is provided at its ends with brackets 25 on which is supported a clamping rod 25 which extends across the machine, being mounted at each end in a lever 27. Each lever 22 is pivotally mounted at 28 in the rear end of the corresponding bracket 25 and the clamping rod 25 has its ends secured to the swinging end of the corresponding lever 21. The clamping rod 25 is operated by a handle 29 shown in the form of a rod extending across the machine and secured to the clamping rod 25 by short arms 35.

The cutting bar ll carries on its top surface, suitably secured thereto, a cutter 3|, having an undercut edge 32 extending across the machine and closely resembling the cutting edge 5 and a cutting plate 33 corresponding to the cutting plate E6, the cutter and plate being spaced apart providing a cutting slot 35 corresponding to the cutting slot IT. This slot is flared at its ends at 35, this flare being similar to the flare or enlarged opening H of the cutting slot l'i.

Cooperating with the table 5 and extending across the machine and secured at its ends to the side frames 8, we have shown a presser bar 35 which is at the left in Figure 3. This presser bar as shown is of H shaped cross section and is provided at its bottom side with a relatively movable presser foot 31 extending across the path of the web 4r from side to side and having secured to its bottom surface, a pad 38 adapted to bear on the paper as more fully hereinafter described. The presser foot 3'! is given a downward tendency and pressed against the web on the table 5 by means of springs 39 shown as coiled about the vertical studs 49 which extend downwardly through suitable holes in the cross arm ii of the H shaped presser bar and are threaded at their lower ends into the presser foot 31. The springs bear at one end against the bottom surface of cross arm 4! and at the other end against the top of the presser foot 3?. The springs 39 and screws or pins 49 are shown as five in number, spaced across the machine to apply a uniform downward tendency to the presser foot.

The rearmost top edge 43 of the H shaped presser bar 36 serves as a track on which the follower rolls 42, of the carriage I, bear in operation as the carriage moves across the machine. The presser bar is also provided at its lower rear side with a toothed rack 54 extending across the path of web and suitably secured and spaced outwardly from the presser bar.

The cutter carriage I, which is removable, being provided with a handle 55 by which it is moved and operated, though it may be actuated in any suitable manner, is best illustrated in Figures 3 and 4. The frame of this carriage I, as seen in Figure 3, which is a section in a plane extending longitudinally of the web, is of inverted U shape, the handle 55 being the cross arm of the U. The cutter shaft 59, which in the operative position of the carriage extends longitudinally of the machine, i. e., in the direction of feed, has a bearing 5| at the lower end of the rear arm 52 of the U shaped carriage frame. The other bearing 53, near the forward end of the shaft is supported in an offset depending bracket 54 on the forward arm 55 of the U shaped carriage frame. It may be noted in this connection that the rollers 52 are mounted at the lower end of the forward arm 55 of the carriage frame, and that the shaft 59 carries a roller 55 just inside the arm 52 which rolls on the paper web 51 where it overlies the cutting plate 33 carried by the cutting bar l. The shaft 59 carries at its forward end, a toothed pinion 58 which in the operation of the carriage, engages rack 54 by which it is rotated. This pinion is secured to the shaft 55 and it operates the moving cutters or knives I8 and 59 as hereinafter described, the shaft being rotated by the motion of the carriage through said rack and pinion. To cause it to maintain the proper engagement, the pinion 58 is shown as provided with side flanges 59.

The moving cutter or knife [8 is carried on a boss 6! which is keyed to the shaft by means of a key 52 on which it slides and the knife [8 is pressed against the edge of the stationary cutter 5 in operation, by means of a spring 63 which is coiled about the shaft 59 and supported oppositely to the cutter by means of a collar 64 secured to the shaft.

The shaft 59 also carries a collar 55 loose on the shaft, to which collar a shoe 66, which runs on the paper web 34' where it overlies the cutter 38, is secured. This shoe has the effect of smoothing and holding the paper at the point of cutting and oppositely to the roller 55 and clamping the rod 29. The loose collar 55 rests on one side against the collar 64 and on the other side against the collar 61, likewise secured to the shaft, by which collars 64 and El the shoe is positioned.

The cutter 59 is carried by boss 68 which is connected to the shaft by key 69 on which the cutter is permitted to slide along the shaft and this cutter or knife 59 is pressed against the cutting edge 32 of the clamping bar cutter M by a spring 15 which is coiled about the shaft 59 bearing at one end against the cutter 59 and at the other end against a collar H secured to the shaft, against which collar H on the opposite side, the roller 55 also has a bearing. Both cutters l8 and 59 are shown as of the circular disk type.

It is also of interest that the hand of the operator is protected from the knife or cutter l8 by a casing or cover H which surrounds the upper arc of the cutter, being secured to the bracket 54 as shown.

Referring to Figure 2, it will be noted that the machine is provided with supporting rollers for the web indicated by reference characters 72 and 13 at the rear end front respectively of the table 5 and approximately .on the level of the table and to provide the necessary degree of yielding and taking up, the rear roller 12 is mounted in bearings it which slide substantially at right angles to the arc of engagement of the roller with the paper, being supported by springs 15.

It is also of. interest that the waste end or let off roll bearing 3 and also the take up or continuous web roll bearing 4 are made in halves with the upper section 75 hinged at one end and secured at the other end by means of a butterfly nut ll. This provides for removal and replacement of the shafts 3 and 4 for convenience in changing rolls or roll cores 3" and 4". To regulate the tension of the web in transferring from roll 3" to roll 4 after splicing and to prevent unrolling at other times, the roll shaft 3' is preferably provided with a brake 19 shown as consisting of. two brake shoe arms, one on each side of the shaft 3', pivotally connected at 80 at the bottom and drawn together at the top by means of a night and left-handed screw 8|, operated by a hand wheel 83, the shaft 3 being shown as having secured thereto a brake drum or brake disk 82, engaged by said brake shoe arms.

In Figure 2 we have also shown an electric motor |8ll for operating the take up or main roll 4" whereby the spliced web 4:2 is drawn through the machine and formed into a roll 49: to be transferred to a printing press or for any purpose for which it may be available, a completed splice being shown at I02 in Figure 2. The motor shaft I83 is connected by a suitable coupling 84 to a worm shaft 85 mounted in bearings 86 in a frame 8! mounted on a suitable bracket 81' on the side frame 8. This worm wheel operates a worm gear 88 secured to a shaft 89 which carries also secured thereto, a pinion 9|] which meshes with a toothed gear 9| secured to the take up roll shaft 4.

Figure 2 shows the side frame 8 nearest to the observer as provided with a shelf or bracket 92 for a hand operated electric iron 93 which is similar to the flat iron or sad iron used in pressing. This figure also shows a shelf or bracket 94 on which the cutter carriage I, with the various equipment it carries, may be placed when not in use, the carriage being removed by hand from the table after cutting and prior to the operation of splicing, being returned to its position on the table for the cutting operation when the splice has been moved forwardly and the next pair of ends to be spliced have been arranged for trimming or cutting as shown in Figure 3. The cutters may be otherwise arranged.

In the operation of the machine, the take up core or main roll 4" preferably in tubular form, is first mounted on the shaft 4 which is removed from the machine for this purpose, the bearings 4 being opened as described by unscrewing the thumb nuts H and swinging the top bearing member J6 backwardly to release the shaft. The take up roll or roll core 4" may be secured in any suitable manner as by means of cones 95 which are well known for this purpose. A waste end of paper web 4r" wound on the core or roll 4 is placed in position on the machine, the top half. 16 of bearing 4 being closed and the nut 11 tightened. For this purpose, i. e., in starting, a waste end of the kind being joined may be used. This waste end would be delivered to the machine wound on a tubular core or cylinder 4, the same having preferably served as the core of the roll as it was presented for printing. The end 96 of the paper web 4.1: is then drawn b-ackwardly to the table which is lowered by turning the shaft with the eccentric l9 thereon, see Figure 3. This has the effect of releasing the presser foot 31 permitting the end of the web 420" to be entered between the table and the presser foot and passed over the table. The paper being smoothly arranged under the presser foot and drawn fiat, the table is then raised by the operation of. the eccentric clamping the web 4.7:" between the table and the presser foot. A waste end 3r on a roll core 3" is then mounted on the let off shaft 3 which is removed for this purpose, the roll core being secured on the roll shaft 3' by means of cones 99 or in any suitable manner. The let off roll shaft 3 is then replaced in its bearing 3 after the manner of shaft 4. At this time, the cutter bar is raised and the clamping rod 26 is released and the path of the carriage.

from the groove 24. The web 3.1: is drawn forwardly under the cutter bar I which preferably has a bottom pad 98 as shown. The web is then drawn upwardly on the front side of the bar and backwardly over the cutter 3| and the cutter plate 33 which causes it to cross the slot 34. It is then drawn downwardly at the rear side of the bar, all of the slack being taken up. The clamping rod 26 being operated by the handle 29 is then forced downwardly into groove 24, being swung about the center 28, whereby the end edge of the web is clamped. At the time of clamping the cutter bar is permitted to swing downwardly, resting by its weight on the two webs 96 and 91.

The cutter carriage is then grasped by the operator who holds it by the handle 46 and moves it from the shelf 94 to a position on the table at either end beyond the ends of the cutters and plates 6, l6 and 3|, 33. The pinion 58 on the shaft 59 of the cutter carriage i is at this time engaged with the rack 44, the rollers 42 being on the track 43 and the roller 56 in line with the waste end 33: where it overlies the cutter bar at one side of the moving cutter 59, the shoe 66 being in line with the paper where it overlies the cutter bar on the other side of cutter 59. The knives or moving cutters i8 and 59 are at this time in the flared ends of the slots l1 and 34, the said knives being in their initial position prior to the cutting stroke 3 and the springs 63 and H3 partly expanded. The carriage is then advanced from this position along the table and across the webs. The flaring ends of the slots have the effect of allowing a certain amount of variation of the position of the knives on the shaft 50, permitting some variation inthe expansion of the springs 63 and I9, and they also provide for some variation in the position As the carriage advances to cutting position and across the webs, the springs maintain the cutters l8 and 59 in close contact with the cutting edges 6 and 32, even though there be some variation from the straight line which it is intended that these cutting edges 6' and 32 shall assume and possibly some variation in the path and the vertical angle of the carriage. The undercut arrangement of the edges of 6 and 32 as aforesaid eliminates any chance that the portion of the cutters or cutter plates 6 and 3| below the cutting edges may protrude beyond the respective cutting edges, thus holding the knife out of contact with the corresponding cutting edge and interfer ng with the precision of the cut.

In the cutting operation, the end of the web 450" is held fiat and pressed firmly against the table by the presser foot 3'! on one side of moving cutter |8 and on the other side of said outter by the cutter bar I, the pads 38 and 98 thereof bearing directly against the paper. This provides for a clean cut severing the end of said. web without crinkling or disalignment. The end of the web 3x which is folded upwardly and backwardly over the cutter bar I is held between the cutter bar and shoe 66 on one side of cutter 59 and on the other side of said cutter 59 between said cutter bar 1 and the roller 56 which advances across the web 350. In the form shown the cutter 3| forms the surface of the cutter bar 1 beneath the shoe 66, and plate 33 forms the surface of the bar beneath roller 56. The contact described holds the paper flat and reasonably taut in the path of the moving cutter 59 providing a clean severance of the end of the Web 3.2: whereby it is trimmed in parallel with the similar trimming of web 33:". The pinion 58 by its engagement with the rack 44 gives the desired rotation of the shaft 55 and knives l8 and 59, though this trimming or cutting operation may be otherwise performed. It is of importance that the construction described provides for the holding and simultaneous trim ming of the two end edges of the respective webs to be joined, the trimming cuts being parallel and the end of one web being turned back upon itself so that it can be laid back after cutting, in which position it overlaps the other cut end in position for splicing.

It is also of interest that the cutter bar on which this folded end is supported also serves to hold the other web on the corresponding side of its cutter during cutting.

After the passage of the cutter carriage l with the knives l8 and e severing the end portions of the webs 3a: and ix", an adhesive strip or other form of adhesive is laid along one or both of the end edges of the webs and the end edge of the web 3;: being released is swung downwardly and laid on the end edge portion of web 55, the carriage i being preferably first removed and laid on the shelf 94. When the edges are thus arranged, the iron $3 being duly heated, is passed across the table over the overlapping edge portions of webs 35c and ist, causing them to adhere closely, or they may be caused to adhere in any other convenient manner, forming the splice G2 which joins webs 3.": and 53:" forming the continuous web 33:. The table being then lowered by operation of the eccentrics iii, the cutter bar 1 remains suspended as in Figure 2 by means of stops 2!, see Figure 3. The presser foot Si is also sup-ported out of contact with the web. The motor i8@ is then operated rotating the shaft i and the roll or roll core 4" winding the combined web 4a: thereon and unrolling the waste end from the let off or roll core 3", which is controlled by the brake Hi to give the desired tension of the weband prevent premature unrolling.

When the waste end has been completely unrolled and wound onto roll 4x, a new waste end roll is supplied and its tube or roll core 3 afiixed to shaft 3, the empty core 3" being first removed. The trimming and splicing operation is then repeated. When a continuous web 49: of sufficient length is wound upon the takeup roll core 4", it is removed and a new web is started in the manner described.

By means of the machine and operation described, the waste ends of paper rolls which are too short to be available for printing in accord ance with the present practice, are formed into a continuous web with little loss of time and rolled ready for use after the manner of the standard new roll the saving in this way being very large in proportion to the cost of the machine, which is simple, easy to operate without skilled labor and capable of production and operation on a very economical basis.

We have thus described specifically and in detail, a machine embodying the features of our invention in the preferred form and the manner of operating the same in order that the manner of constructing, applying, operating and using the invention may be fully understood, however the specific terms herein are used in a descriptive rather than in a limiting sense, the scope of the invention being defined in the claims.
