6 Claim.

This invention relates in general to the wrapping of packages and has more particular reference to the provision of an improved method and apparatus for severing predetermined portions E3 of a sheet or strip of paper to be used in the packaging so that displays carried by the paper may be accurately and definitely located in the wrapping.

The invention has for its principal object the lit provision of an improved method and apparatus (and also an-improved supply sheet) for providing individual printed wrappers, definite display portions of which may be uniformly and automatically arranged in predetermined position on 1d the package by usual or preferred wrapping machines.

An important object of the present invention is the accomplishment of the accurate arrangement of the display portion of package wrappers upon the package without requiring perforation or other formation of the material of the paper sheet to accomplish the desired registration.

Numerous other objects and advantages of the invention will be apparent as it is better under- Qd stood from the following description, which, taken in connection with the accompanying drawings discloses a preferred embodiment thereof.

Referring to the drawings,

Figure 1 is a side elevation of an end of a machine or apparatus for severing a large sheet or strip of paper into individual wrappers;

Fig. 2 is a top plan view thereof;

Figs. 3, 4 and 5 are sections taken respectively substantially upon the lines 3--3, Hand 5-5 of Figs. 1 and 2;

Fig. 6 isa section taken substantially on the line 6-6 of Fig. 4; and

Fig. 7 is a schematic view, showing the wiring diagram.

For the purpose of illustrating the present invention, there is shown in Figs. 1 and 2 so much of a machine in which it is or may be embodied as to permit understanding of the invention. The partial machine there shown-discloses the entire sheet cutting mechanism and its control. This cutting mechanism and control may form a part of a package wrapping machine.

The operative parts are mounted upon a support 11, having a table portion 12 across which a sheet or strip of paper 13 is adapted to be moved. The strip or sheet of paper 13 conveniently is originally provided in a roll 14 adapted to be rctatably supported at 15 in upstanding bearing brackets 16. This sheet or strip of paper is provided with display portions or designs 17 printed thereon and which are to be arranged in predetermined location upon each of the packages wrapped. The sheet or strip carries also cutting. indicia 18 for controlling the severance of the sheet as it passes across the support 11, all as will be presently more fully described.

Feed rollers appropriately arranged are provided to feed the sheet or strip of paper across the support, a pair of feed rollers being indicated on the drawings by reference characters 19 and 66 21.

Severance of the sheet or strip into individual wrappers is accomplished in the instant embodiment by conjointly rotating or rotatable cutting cylinders 22 and 23 having companion cutting dies or shear members 24 and 25. It is intended that when the apparatus is operating upon rela tively large areas of paper provided with display portions, this cutting means will be operated and controlled in accordance with the location of the 35 display portions themselves and through the primary agency of the printed indicia 18. This printed indicia is so arranged with respect to the display portions that control of the cutting means by the location of the indicia will accurately arrange the display portions upon the predetermined desired part of the wrapper.

To accomplish this, a control is provided for the cutting means which includes a light sensitive device in turn controlling an electric circuit which determines accurately the occasions of the rotation of the cutting means. The light sensitive device is preferably a photo-electric cell of known construction and internal wiring. As shown on the drawings it comprises a source of light 26, which is or may be an electric light bulb arranged to reflect light onto the paper and from it to a light sensitive or photo-electric cell 27, as indicated by the arrows 28 in Fig. 3.

The electric light bulb 26 and the cell 27 are preferably arranged in individual compartments 29 and 31 of a housing 32 carried by an arm 33 from one of the side bearings 34 of the sheet feeding roll 19. This housing is mounted above the path of travel of the indicia 18, which indicia is preferably merely printed black dots or spots upon thepaper, a such dot or spot being provided for each intended cutting operation. As each dot or spot passes beneath the housing and across the reflected light from the bulb 26 to the cell 2'7, the cutting mechanism is connected to the power to perform a cutting operation through electrical devices to be presently described.

The two cutting rolls 22 and 23 are geared together as indicated at 35 and are fixed on on the presented hub face of the pulley 38 by a spring 44.

The dog 42 is movable laterally of the plane of the pulley 38 in a dovetailed slot in the clutch 41 and is provided with a tapered transverse slot 45 generally in registration with a circumferential slot 46 in the clutch. A lever 47 having a vertical movement is pivoted at 48 in a lateral extension 49 o f the adjacent bearing 51 for the shaft 36. This lever is adapted to be moved down away from the clutch by a solenoid 52 and a spring 53 acts to press it into the slot 46 and into the slot 45 when rotation of the cutting mechanism presents the dog 42 to the lever. a dot or spot presents itself to the housing 32, the solenoid is energized, the spring 53 contracted, and the lever moved downwardly from the position shown in Fig. l. Thereupon, the clutch dog 42 is pressed by the spring 44 into clutching engagement with the teeth 43 on the hub of pulley 38' and the cutting instrumentalities are rotated. Before this rotation is complete the spot has passed the housing 32, the solenoid 52 is deenergized, and the lever 47 is moved up by the spring 53 in position to withdraw the dog 'at the end of a complete revolution.

A. brake 54 is or may be provided to cause prompt termination of the rotation of the cutting mechanism as soon as the dog is withdrawn.

Reference character 55 indicates a gear which,

is or may be provided in mesh with one of the gears or pinions 56 provided on the shafts of the feed rollers. The gear 55 carries a stud 57 adapted to engage and move one arm 58 of a bell crank pivoted at 59 on the support '11, the other arm 61 of which is arranged to extend over and depress the free end of lever 47. The arrangement of these parts is such that the lever 47 is depressed at the instant the dog 42 passes the lever 4'7 so that the cutting mechanism is continuously operative. This last described mechanism is provided in order that the cutting mechanism may operate upon unspotted paper and when the accurate cutting with respect to particular displays is not contemplated. When the control of the cutting mechanism is to be accomplished by the photo-electric cell, the bellcrank is merely removed from its operative position. The cutting mechanism is thus arrangeable to cut at predetermined regular intervals and arrangeable also for accurate control in accordance with the displays upon the paper.

The electric wiring is schematically shown in Fig; 7. The source of power is indicated by reference character 62. From this source of power one line wire 63 leads through a switch 64 to the winding 65 of the solenoid. From this winding, a wire 66 leads to a movable contact 6'? adapted for engagement with a contact 68 in turn connected by a wire'69 with. source of power 62. A' wire 71 leads to lamp 26 from one side of the source of power 62 and a wire '72 completes the lamp circuit to the other side of the source of power. The photo-electric cell, generally indicated at '73, is connectedinto a circuit including a solenoid winding 74 for'controlling movable contact 67. The details of the wiring of the photo electric cell are not believed nece sa y o a Each time understanding of the present invention, it being understood that alteration in the reflected light to the cell 73 accomplishes a change in the current flowing through solenoid 74 and consequent movement of the contact 67 into engagement with the contact 68 and then back to its separated position.

It is thought that this invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.
