13 Claims.

This invention relates to a means for applying reinforcement to sheet material, and more particularly to an apparatus for afilxing a wire to or at the edge of a sheet in order to prevent, the sheet from curling.

In the manufacture of display sheets of various kinds, as for instance in the manufacture of large size calendars from ordinary sheet material, usually a single perforation or other centrally located means is provided in order to hang the calendar or other display sheet in a suitable location. Where such a centrally located hanging device is so provided, then where the sheet has any substantial width, it tends to curl or sag about the hanging device as a center.

Accordingly, in large size calendars, it has long been customary to apply a very light gauge sheet of tin over the top and bottom edges in order to prevent the curling from occurring.

Various other means have been used in order to stiffen the horizontal edges of the hanging sheet so that, it will not be wrinkled or tend to fold over. I have found that instead of applying such a tin edge facing or other types of facing or reinforcing members to the horizontal edges of the hanging calendar, that it is a far more practical expedient to apply a wire reinforcement to such edge. The use of a wire reinforcement tends to simplify the manufacture of the calendar or other display sheet and lends itself readily to z the use of the improved apparatus herein described.

In general, an object of my invention is to so arrange a calendar or display sheet that when hung at its upper edge by a centrally located perforation or other hanging means, the said calendar or display sheet will not curl.

Another object of my invention is to form a simplified reinforcement comprising principally a wire and an adhesive strip affixing the wire to the sheet along the upper and, if desired, the lower edges in order to prevent the curling from taking place.

Still another object of my invention is to provide a novel, simple and economical method and machine for affixing the wire to the sheet by an adhesive strip.

Other objects of this invention are to provide in such apparatus a means whereby the wires may be continuously fed, as desired, and whereby the adhesive strip may be continuously and automatically fed for each afiixing operation, and other methods and means whereby it may be entirely simplified.

Other objects and uses of this invention will in part be apparent and in part be pointed out in the following description and drawings in which:

Figure 1 is a sectional schematic view taken on line l--l in Figure 4 illustrating in diagrammatic form the method and apparatus for affixing the reinforcement of the type herein described.

Figure 2 corresponds to the wire affixing portion of the device schematically illustrated in Figure 1, showing the device at the moment just after thecommencement of the affixing operation.

Figure 3 corresponds to Figure 2, showing the operation immediately before the completion thereof.

Figure 4 is a front sectional view of the adhesive strip and wire reinforcement applying portion of the apparatus taken on line 44 of Figure 1.

Figure 5 is a plan View taken along the line 5-5 of Figure 1, looking in the direction of the arrows.

Figure 6 is an end view of the switching mechanism taken from the arrow B of Figure 4.

Figure '7 is an end view of the wire feeding ratchet taken from the point 1 of Figure 4.

Figure 8 is an enlarged detail of a portion of the wire feeding device of Figures 1, 2 and 3.

Figure 9 is a view in perspective partially broken away of the wire reinforced display sheet.

Referring now to Figures 1 to 4, the display sheet or calendar sheet i!) may be inserted in the machine by the operator, such insertion being guided by the side gauges H, and the rear gauge bar 62 (see also Figure 5).

Where desired, a pair of side gauges may be used, although actually it will be seen that the rear gauge bar 42 and one side gauge H are sufficient to properly arrange a rectangular sheet, particularly when the two gauges are at right angles to each other. As is also obvious, the display sheet i6 is laid upon the bed 13 of the machine but the sheet itself projects beyond the bed [3 to the area. where is may be operated upon by the knives and the punch as hereinafter described.

Once a sheet has been acted upon to produce a reinforced edge, it is immediately removed, another sheet is inserted in the same position, and the operation repeated.

The reinforcing wires l5 to be applied to the sheet and to be secured thereto by an adhesive strip are retained in the hopper Hi. The adhesive strip H which affixes the wire at the edge of the sheet is drawn from the movable web l8 which, in turn, is led from the roll I9 through the guides over the moistener 2| beneath the pressure and feed roll 22 to the wire applicator. The web I8 from which the strips ii are cut preferably comprises a continuous sheet of paper having a re-moistening adhesive surface.

The moistener 2| comprises a tank 23 containing water and having a roll 24 partially immersed therein. Rotation of roller 24 will, by reason of the pressure thereon of pressure roller 22, cause the web |3 to be advanced in the direction indicated by the arrow 25. The additional guide roll 26 serves to insure contact of the web l8 with the moistening roll 24 in order that the remoistening adhesive surface of the sheet or web l8 may be rendered adhesive. 7

Figure 1 illustrates the reinforcement applying apparatus just before the commencement of the operation. The eccentric 3|) is mounted on the rotatable bar 3| and is keyed thereto to rotate therewith. The said eccentric 33, however, rotates within the circular member 32, the said circular member being pivotally connected at 33 to the punch and wire applicator itself.

By reason of the eccentric mounting of the member 30 upon the rotatable bar 35, rotation of the said rotatable bar 3| will cause the circular member 32 to rise and fall in accordance with the relative position of the maximum and minimum radius of the center with respect to the rotatable bar 3 I.

Thus in the position shown in Figure 1, the circular member 32 is at the highest point of its period of vertical oscillation and the reinforcement applicator and punch is at the point at which one operation has been completed and the display sheet In should be removed and a new display sheet I3 should be inserted for the next operation.

Each operation, as is hereinafter more clearly pointed out, consists of a single rotation of the bar 3| from the position indicated in Figure 1 and back to the position therein shown. In order to initiate the operation, the power drive of the bar 3| may be connected by a clutch which wil be disengaged immediately upon the completion of the operation or in order to insure that the operation will come to a halt in the exact position shown in Figure 1, a brake may be automatically applied at the conclusion of the operation or a mechanical stop may be applied so that depression of a foot pedal will throw a clutch mechanism into engagement connecting the rotatable bar 3! to the power source and at the same time will momentarily throw a mechanical stop out of alignment, throwing the same mechanical stop back into position to engage the member once more upon completion of.

its revolution for throwing a similar member into such position, said mechanical stop also disengaging the clutch at the completion of the revolution.

The actual means which will permit the rotatable bar 3| to be rotated quickly from the position shown in Figure 1 until it returns to the same position is not itself important. Many such mechanisms are commonly known and any of them may be readily adapted to this periodic controlled rotation. The invention herein comprises, not the method by which the rotatable member 3| is caused to rotate in this manner, but the actual use which is made of such single cycle rotation.

When the sheet H1 is placed upon the bed I3 of the reinforcement applier in the manner hereinbefore described, and is placed against the gauge bars II and I2, then a single rotation of the rotatable bar 3| will result in the following, operations:

The eccentric 30 will immediately be rotated and because of the variation of maximum and minimum radius within the circular member 32 will necessarily cause the said circular member 32 to drop. The circular member 32 is connected by the arm 34 to the frame 35 of the actual wire applicator and punch. In order to permit the rise and fall of these members in spite of the fact that the circular member 32 may shift periodically from the vertical plane, the connection is preferably through a pivoted member such as the pivot bar 33. The rear gauge bar 2 is mounted on the frame 35 and as the said frame 35 descends, the gauge bar I2 is carried below the plane of the bed I3.

At the moment of inception of the rotation operation of the member 3|, the cam portion thereof 36 will come into contact with the pin 31. The pin 31 will press back the arm 38 of the lever 39 which is pivoted about the pivot 40. Pressing back of the arm 38 of the said lever 39 will cause a corresponding rotation of the opposite end 4| of the lever and thus will cause the subsidiary wire chamber 42 to permit the individual wires l5 to be dropped down into the position indicated by the dotted lines.

While the member 39 comprising the arms 33 and 4| has been described as a lever actually it should be noted that the member 4| will be a fiat planar member extending across the subsidiary wire chamber 42 in order to hold the wire in place. The operation of the entire mechanism may well simulate that of a lever.

The arm 38 may, however, be mounted only on one side of the machine to register with the cam member 36 which is mounted upon that same side of the rotatable bar 3| (see particularly Figure 4). As seen in Figures 4 and 6, also, immediately upon the inception of the descending movement of the frame 35, contacts 45 and 46 of the switch 4'! will come into contact with each other, thus simultaneously energizing the magnets 48. Thus, at the same time that the subsidiary wire chamber 42 is opened by a movement of the member 4| to permit the wire l5 to be dropped out, the energization of the magnets 48 at the two effective terminals thereof 49 and 50 (see also Figure 5) will cause the wire to be alinost instantaneously aligned in the proper posiion.

Now the continued rotation of the rotatable member 3| and therefore of the eccentric 32 in its further causing the descent of the frame 35 causes the knife on the frame to engage the stationarily mounted opposed knife blade 6| which is mounted in the plane of the bed |3 in order to shear off the strip I! from the continuous web It]. As this shearing operation takes place, the rubber or other flexible cushion 62 in the same plane as the descending knife blade 60 presses down the adhesive strip I? about the wire |5 and by reason of its yielding surface causes the adhesive strip to be wrapped around the wire as well as upon the paper in the manner shown in Figure 9.

At the same time, the motion or rotation of the rotatable member 3| causes the pin Til to be rotated and during the downward motion of the adhesive applicator, the rotation of the pin 10 causes a motion of the link H in the direction indicated by the arrow 12, thus causing a movement of the pivoted link 13 which carries the pawl 14. As will be noted, the pawl 14 in such downward movement in the direction indicated by the arrow 12, passes over the ratchet 15 in a direction which will not result in rotation thereof.

It should be here noted that the ratchet 15 is fixedly keyed to the rotatable applicator and feed roller 26. By this downward motion, preparation is made for the feeding of the continuous web l8 into the applicator during the upward stroke.

During the descent of the frame 35 it will be noted that the punch 80 in the frame 35 registers with the female die 8| to produce perforation 82 (see also Figure 9) by which the calendar or display sheet may be hung. Ordinarily, in the manufacture of the display sheet, it is necessary to apply the perforation 82 at the center of the upper edge only, it not being necessary at the lower edge. For this reason, the punch 86 is mounted on a bar 83 which is hinged at 84. The pin 85 engages the bar 83 and by means of the threads 86 at the opposite end of the said pin, which engages with the frame member 35, serves to secure the punch 88 in place. When it is desired to make a run of unperforated reinforced edges then the unscrewing of the pin 85 and the lifting thereof will remove the punch 80 from the operative position so that reinforced edges will be created without perforations.

When the reinforcement applying operation is completed at the lowest point of the stroke, that is when the maximum radius of the eccentric 32 is in the position shown in Figure 3, then the punch 80 has entered the perforation 8i, creating the perforation 82 in the sheet It, the knife 60 has cut off the strip I7 and the member 35 starts on its upward stroke.

The gauge bar i2 then lifts the cut end of the strip [8 (see Figure 3) above the plane of the bed 43. At the same time, the continued rotation of the member 3| resulting in continued rotation of the pin 78 results as hereinabove pointed out in continued movement of the link H, causing the pawl M to engage the ratchet 15 in a manner causing the rotation thereof, and causing a corresponding rotation of the adhesive ap plying roll 2a which, by reason of the pressure of the roll 22 causes an advance of the web IS so that another strip ll comes into place immediately above the display sheet it which has already been operated upon.

Immediately after the cam portion 35 of the rotatable member 3| has passed the pin 57, thus releasing the wire i5 so that it may enter into position for being fastened to the display sheet If! and immediately after the subsidiary wire container 52 is closed by the action of the spring Hit in pulling back the bar 38 to its original position, thus pressing down the member 4i once more, then the pawl Hi3 attached to the frame member 35 engages the ratchet iii which is securely keyed to the same shaft as the grooved roll H2.

The engagement of the pawl lit with the ratchet HI during its momentary contact with the ratchet in the descent of the frame 1 5 is sufiicient to cause such a rotation of the grooved roll I I2 as will bring another groove it into posi tion to discharge a wire into the subsidiary wire container 4 2 thus preparing the wire for the next operation. It will be noted that the placement of the wires [5 in the hopper I5 is such that certain of the wires will enter each of the grooves H3 in order to make this last operation possible, For this purpose in packing the hopper i6 care should be taken to arrange the wires exactly at right angles to the sides of the hopper so that the wires may readily enter the grooves H3.

The rotation of the roller 3! ceases when itagain reaches the position shown in Figure l at which time the reinforcement has been applied to the display sheet H), a perforation made therein adjacent the reinforcement, if desired, an additional strip H has been placed in position for the next operation and an additional wire i5 has been placed in position in the subsidiary wire hopper 52 in preparation for the next operation.

It is now necessary merely to remove the dis--v play sheet ii), insert another display sheet to register with the rear gauge bar [2 and the side gauge H, and to repeat the operation. It will be noted that the dropping down of the rear gauge bar l2 during the cutting stroke and the return thereof during the return stroke of the blade serves to support the web 1 8 sufficiently to permit it to be advanced and not wrinkled so that a suflicient area may project beneath and beyond the knife to form the strip I1. Likewise, during the removal and reinsertion of a new display sheet, the rear gauge bar [2 serves to support the projecting strip ll until it is out.

The wire reinforcement herein described. while itlends itself readily to stiffening of the edge of a calendar or any other display sheet, may be applied to any article where a wire and tape reinforcement of the type set forth herein may be used.

Although the use of a wire facilitates and simplifies the operation, other types of reinforcing members may be applied. Thus, with suitable variations in the feeding operation, strips or members of any desired shape, conformation and composition may be utilized.

Where the tape or strip is sufficient in relative strength or thickness to provide reinforcement, then the wire applying operation may be dispensed with.

Many of the uses of this article will be clear to those skilled in the art. Accordingly, I prefer to be limited, not by the specific disclosures herein, but only by the appended claims.
