LABEL CUTTING AND FbLDINe MECHANISM Filed Sept. 8, 1958 ATTO NEY5 Patented Aug. 20, 1940 UNITED STATES PATENT OFFICE to Rose Patch & Rapids, Mich.

Label 4 Company, Grand Application September 8, 1938, Serial No. 228,925-

8 Claims.

This invention relates to label cutting and folding mechanism, and particularly to the mechanism for cutting, folding and balancing labels. It has for its objects:

First, to produce a new and improved machine of the type described.

Second, to provide such a machine which is capable of handling woven labels which are fed face up to the cutting and folding mechanism.

Third, to provide a new and improved balancing mechanism for use on such a machine.

Fourth, to provide such a balancing mechanism which may be adjusted accurately and sensitively to operate on the raised portion of the face of the label.

Fifth, to provide such a machine in which felt covered pull back means are employed to engage tion, so that the feeding means need not pull the label strip directly from the supply roll.

Other objects and advantages pertaining to details and economies of construction and operation will appear from the description to follow. The

invention is defined in the claims. Preferred embodiments of my invention are illustrated in the accompanying drawing, in which:

Fig. 1 is a diagrammatic view showing my improved machine.

Fig. 2 is a detail view showing the balancing and pull back mechanism.

Fig. 3 is a plan view of the mechanism shown in Fig. 2.

In the machine shown, I is a supply roll from which the label strip 2 is fed. 3 is the balancing mechanism and 4 the pull back means. 5 are the feeding jaws. 6 is the knife for severing the label from the end of the strip. 8 is the folding mechanism and l is the packing mechanism to receive the cut and folded labels.

In the operation of the machine, the feeding jaws 5 reciprocate along the line of travel of the label strip 2 and for each reciprocation, feed the label strip 2 substantially one label length. In operation the jaws 5 grasp the label strip at the position shown in Fig. l and advance it' through the knife to the folding mechanism. The knife 6 then severs an individual label from the end of the strip. The label strip on which the machine operates is a woven strip. On the face 9 of this. strip raised insignia III are formed by weaving. These insignia may either be a trade-mark or some decorative matter which must be properly centered on the finished cut and folded label. The

balancing mechanism 3 and the pull back means I serve to properly center or balance the insignia. The label -strip may also have thereon raised portions III! which may be used in balancing the label instead of using the insignia l0 themselves, although with my machine it is possible to obtain satisfactory results using either the insignia ID or the raised portion I I0.

After an individual label is severed from the end of the strip, the strip is released so that it may be pulled back along its line of travel. This pulling back of the label strip must be checked with the insignia of the next label in the proper position so that the forward feeding will properly center the insignia for severing and folding. This pulling back of the label strip is accomplished with the pull back jaws 4 which reciprocate along the line of feeding the label strip. These pull back means 4 are effective to pull the strip back until the balancing means 3 engage the raised insignia ll! of the face of the label as shown in Fig. 2 or one of the raised portions N0 of the face of the label. The reciprocation of the means 4 is so timed that the reciprocation to the left; in Fig. 1 is: obtained after the label has been severed from the end of the strip and before a new feeding cycle starts.

The balancing means consists of a bed II over which the label strip 2 passes face up. A support 12 is provided having a way I3 in which a shaft 14 is fitted for movement transversely of the label strip. A suitable screw I5 is arranged to hold the shaft in adjusted position. This permits the adjustment of the balancing mechanism to engage the face of the label strip at any point on a. transverse line across the label.

A fixed arm 16 is provided on the shaft and a pivoted finger I1 is provided on the end of the shaft. This finger has a blade l8 thereon. This blade l 8 is a thin sheet metal blade and-the finger I1 is weighted sufficiently to hold the blade to the desired down position, although permitting the feeding of the label strip without hindrance. A screw I9 is screw threaded in the finger l1 and engages a lug portion 20 on the fixed arm It. This permits very accurate and delicate adjustment of the position of the edge of the blade IS with reference to the bed II. It will be ap- -parent that backward movement of the label strip along this line of movement will be checked or arrested by 'engagement with the blade II against the insignia III of the label strip.

Heretofore it has been considered necessary in balancing labels to have the balancing means engage the back of the label strip. Ordinarily in weaving the insignia III or a raised portion Ill! into a label strip, the portion of the insignia In or raised portion H on the back of the label strip extends from the back of the strip more than the insignia or raised portion extends from the face of the strip, making it easier to obtain engagement. The portions extending from the back of the label strip, however, are not as tightly woven as the insignia I ll or the portions H0 on the face of the label and consequently it is not possible to obtain as accurate a balancing in this manner as is possible if the insignia or raised portion on the face of the label is employed. It has been impossible, however, with existing mechanisms to utilize the insignia ill or raised portion H0 on the face of the label strip which can be accomplished by using my invention.

Adjustment of the balancing mechanism along the line of feeding of the label strip is obtained through a screw 2| having a knurled end 22. This may be accomplished while the machine is in operation, greatly speeding up adjustment.

The pull back mechanism consists of a lower member 23 mounted in ways 24 for reciprocation backward and forward along the line of movement of the label. A projecting lug 25 is engaged by the arm 26 having cam followers 21 in engagement with the lug 25 to permit reciprocation in both directions. The arms 26 are reciprocated in time with the rest of the machine and reciprocate back along the line of feeding of the strip after the label strip has been released following the severing of the individual label from the end thereof. The upper member of the pull back mechanism is shown at 28 and is provided with a knob 29 for raising the same. It is apertured at 30 to receive pin 3| extending from the face of the member 23 to position the upper member 28. The label strip 2 passes between the

members r

23 and 28 and they are provided respectively with felt

label engaging faces

32 and 33.

It will be apparent that these faces will grasp the label on reciprocation of the pull back mechanism 4 to the left as viewed in Fig. 2, and thus the label strip 2 which is then released will be pulled rearwardly or backwardly along the line of its movement. The label strip is held frictionally between the

faces

32 and 33, and when the blade iii of the finger I1 engages the raised insignia of the label, there will be a slipping of the pull back mechanism along the label strip. It is possible by the use of the felt faces 32 and 33 to obtain a very delicate adjustment which permits the blade l8 to engage the insignia on the face of the label.

Delicacy is obtained in a manner hitherto not possible and the weight of the member 28 is such that the frictional engagement of the

faces

32 and 33 with the label strip 2 is such that the released label strip is pulled back freely, although the label strip slips freely and evenly between the

faces

32 and 33, either on engagement of the blade l8 with the raised insignia or upon operation of the feeding means to feed the label strip. This eliminates the necessity for any mechanical means for releasing the pull back mechanism when the label strip has been pulled back to the proper position.

It is desirable to have the label strip 2 free for feeding. If it is pulled directly from the supply roll I the feeding mechanism may be overtaxed. By employing an arm 34 pivoted at 33 having a portion 3! which lies over the label strip, this is overcome. The label strip is engaged between the balancing mechanism 3 and the supply roll I. Cam 31 having a heart-shaped groove 38 engaging a cam follower 39 on the arm 34 is timed to reciprocate the arm downwardly after the balancing mechanism 3' has engaged the insignia of the label strip so that a loose loop of the label strip is pulled from the reel I for feeding. This avoids overloading the feeding means 5 and thelabel strip is fed more evenly.

I have shown and described my device in the form preferred by me and wish to claim the same broadly as well as specifically, as pointed out in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
