9 Claims.

This invention relates to machines for cutting and folding cloth labels or the like and has particularly to do with labels for application to the corners of sheets or towels or the like.

The objects of the invention are:

First, to produce a new and improved apparatus for cutting ofi labels of the above specified character and folding over the corners to provide a label which slips over the corner of a towel or sheet and may be sewed in place by a single line of stitching running diagonally across the corner.

Second, to provide such a machine in which the label is severed from a label strip and is grasped by label feeding and holding jaws having a fold form thereon of a triangular shape, which jaws feed the label to folding devices.

Third, to provide such an apparatus which is simple in construction and in operation and which may be operated inexpensively.

Fourth, to provide fold forms and folders that may be employed with label cutting and folding machines already existent.

Further objects and advantages pertaining to detail and economies of construction and operation will appear from the description to follow.

A preferred embodiment of my invention is illustrated in the accompanying drawings, in which:

Fig. 1 is a perspective view of my improved machine.

Fig. 2 is a partial plan view showing the operating parts of the machine.

Fig. 3 is a detail sectional view through the folding apparatus, taken on the line 3-3 of Fig. 2.

Fig. 4 is a detail sectional view taken on the line 4-5 of Fig. 3.

Fig. 5 is a diagrammatic plan view taken on the line 55 of Fig. 2, showing the holding jaws and the jaws for folding the label after it has been folded.

Fig. 9 is a plan view of a label of the type to be operated upon by the machine beforefolding.

Fig. 10 is a perspective view of the finished folded label.

Referring to Fig. 1, I there show a label cutting and folding machine which is of the general type of that shown in Patent No. 1,528,511 granted March 3, 1925, to Martin Rosenthal and myself for Label cutting and folding machine. It is unnecessary for purposes of this application to describe the operation of such machine in detail and I will refer to the operation in general only.

The machine is mounted on a suitable base I 5 and a strip of labels 2 is fed from a supply roll 3 to a cutting knife 4. Label feeding and holding jaws 5 grasp the label and advance it past the cutting knife 4 where it is set, the label having first been balanced by any suitable balancing means such as the foot 6 or by a balancing means such as that shown in my Patent No. 1,984,657, issued December 18, 1934, for Apparatus for cutting and folding labels.

After the individual label has been severed from the strip 2, jaws 1 feed it to a chute 8 or any suitable packing means.

The apparatus is driven by a suitable drive shaft 9 and is so operated that the holding and feeding jaws 5 grasp the end of the label strip 20 and advance it through the cutter to the position shown in dotted lines in Fig. 2. The cutter then operates, severing an individual label which is operated upon by folding means. The label holding jaws are withdrawn from the folder and 25 are moved around the cutter back to the position shown in full lines in Fig. 2 to repeat the operation.

When the label holding and feeding jaws 5 advance to grasp the label, the jaws l grasp the folded label, and when the cutter 4 opens and the jaws feed the label strip through the cutter, the jaws 1 feed the label to the position shown in dotted lines in Fig. 2, and when the

jaws

5 and 1 are moved to the left as in Fig. 2 to withdraw them from the folder, the label is scraped from the jaws 1 by means of the member H).

In my invention, I provide a fold form H on the upper one of the pair of jaws 5. This fold form is of triangular shape as shown at H and the upper sides of its edges are beveled as at l3.

The fold form on the jaws is disposed so that as the jaws grasp the individual labels for feeding, the triangular fold form is disposed above and transversely of the individual label and the apex ll of the triangular iold form is located substantially at the edge of the individual label.

The severed label is then fed to a bed I5 which is recessed at IE to receive a folder H. The folder 11 has a triangular notch therein and is so disposed that when the jaws 5 feed the label past the cutter the fold form i2 is disposed on the bed [6 above and in register with the triangular notch [8 in the fold form I1.

The fold form i1 comprises a flat metallic member it which is suitably bolted on an arm 20 with bolts II. The arm 24 is pivoted at 22 on a slide "and is apertured at 24 to receive a bolt 25 having thereon collars! and 21 between which is located a coiled spring 2| held in place by the collars which are in turn held in place by a nut 29 and the arm 20. The spring 28 is a compression spring no mally tending to hold the folder in a depressed position with the top of the member I! substantially flush with the bed It.

Means are provided for raising the folder past the fold form if. When the holding jaws B with the label are positioned above the folder, the member l9 passes up pastfthe foldform if as shown in Fig. '7, folding upthe corner 30 of the label 3|. The label M has a face 32 on which a trade-mark or other 'device may be reproduced and the corners 30 may carry other notations. As shown in Fig. 10,-the label is made specifically for use with sheets, one corner indicating the number of inches of the width of the sheet and the other side indicating that the figure represents the length. The fold form I! covers the back of the face 32 and the corners 30 are the portion bent up.

I The folder I1 is raised by means of a plunger to the position shown in Fig. 7.

33 which contacts a bolt 34 through the arm 23.

. This bolt is screw threaded in the arm as shown in Fig. 3 and is provided. with ali'nurle'd adjusting knob 35 and a look not 33. The plunger 33 is provided with a cam follower 31 by means of which the plunger is raised to raise the folder it After the folder has been raised to the position shown in Fig. '7, it is advanced over the edge of the fold form, bending the. corner 33 of the label to the position shown in Fig. 8 and creasing the same. The spring 28 holds the portion I 9 of the folder i8 yieldingly against the label which is folded around the fold form I 2 as shown, and heat is applied by means of the gas Jets 38.

The advancing of the folder is effected by a bell crank 39 having a vertical arm 40 slotted at 4| to engage a pin 42 on the slide 23. A'horizontal arm 43 has a cam follower 44 and 9. raising of this arm 43 moves the folder back from the fold form, whereas-a lowering of the arm 43 forces the folder l8 to the position shown in Fig. 8.

A horizontal arm 45 is provided on the bell crank lever and has pivoted thereto a connecting rod 46 with a pin 41 and a knurled adjusting nut 48 contacting a compression spring 43 which normally tends to raise the arm 45 and advance the folder to the position shown in Fig. 8.

A cam slide 50 is provided having a cam 5i forengaging the cam follower 31- and a cam 53 to engage the cam follower 44. These cams are so disposed that as the slide 50 slides toward the front as in Fig. 1, impelled by the cam 54 on the drive shaft 9, the cam 5i first engages the cam follower 31 and raises the folder to the position shown in Fig. 7. Thereafter the cam follower 44 rides down on the cam 53, permitting the spring 49 to force the folder I 3 to the position shown in Fig. 8.

The plunger 33 is connected by coacting engagement with lever 55 which is pivoted'at one end at 53 and has the cam follower 31 at its other end. I

A spring 51 holds thecam slide 50 against the cam 54, causing it .toreturnas the machine completes its cycle and causing the folder l8 to assume the position of Fig. 6 preparatory to receiving another label.

The device just described is timed to operate after a label has been severed and fed to the position shown in the dotted lines in Fig. 2, the operation is effected automatically, and the foldingjaws 3 are then withdrawn to'take another label. a

It will be seen that the particular fold form can be substituted for the fold forms on the general type of machine here described and that the particular folding apparatus can be easily substituted for the folding apparatus illustrated on the machines inthe above mentioned patents.
