.19 Claims. (01. 154-,1.6)

This invention relates to improvements in methoda-ndapparatus for printing and applying labels to wrapping paper The -main objects of this invention are:

.First, to provide a method for printing and applying labels to wrapping paper.

Second, to provide a method for printing and applying labels to a web of wrapping paper as it is unwound for wrapping purposes.

Third, to provide a. machine or apparatus as an attachment for .a wrapping machine for printing and applying alabel band or stripv to a web of paper.

Fourth, to provide a machine or apparatus for the practice .of the method .of my present invention which is effective and at the same time compartively simple and economical in structure.

Objects relating to details and economies of the invention will appear from the description to follow. The invention is pointed out in the claims.

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

Fig. 1 is a fragmentary side .elevational view of the machine or apparatus of my invention in operative relation to a wrapping machine frame and the wrapping web roll supporting means thereof.

Fig. 2 is a fragmentary plan view. i

Fig. 3 is a fragmentary view in mainly longitudinal section on a line corresponding to line 33, of .Fig. 2.

Fig. 4 is a fragmentary plan view illustrating certain of the steps of the method of my inven In the accompanying drawing I represents the frame of the wrapping machine. The details of the wrapping machine form no part of my invention and are therefore not illustrated with the exception that the machine is provided with a support 2 for the roll of wrapping paper 3, the web 4 being guided over suitable guide rolls 5, 6, '1 and 8 to the wrapping mechanism. -9 designates a conveyor for material to be wrapped and I one of the supporting members for the conveyor which also serves as a support for the machine or apparatus of my invention.

This machine or apparatus in the embodiment of m-yinvention illustrated comprises a frame designated generally by the numeral H which is "suspended from the part to by hangers l2, The

frame comprises side members l3 and a top .cross member .|4 connecting the same. The printing cylinder I5 is mounted between the, side members on the shaft l6 and is adapted to receive suitable printing plates IT. The ink feed .roll I8 is mounted on the shaft H3 in cooperative relation to the fountain .20.. The cylinder inking roller 2| is provided with ink through an inking couple designated generally by the numeral 22 and including theshiftable transfer roller 23. Inking couples of this character are known in the art and therefore it is not described in further detail.

A motor -24 is .mounted on a bracket .25 carried by the frame and suitably geared to the driving shaft 26- having a sprocket 21. The sprocket?! is connected by .the sprocket chain 28 .to the sprocket 2.9 on theshaftof the printing roller and toasprocket 30 on the fountain orink feed roller shaft. The chainis guided by the guide sprockets .31 and 32. Thelabel strip .or band 4| is desirably supplied in the form of aroll 34 mounted upon the spindle or shaft 35 in suitable relation to the other parts. This label strip or band is made of paper and is passed over the guide roller 36 and between the pressure or-contact roller 31 and the printing cylinder. These rollers are carried by arms 38 and 39 respectively on the shaft 40, they coact to tension and direct the band to the printing roller. The label band or strip 4| is provided with a barrier 42 on one side and a thermoplastic coating 43 on the barrier side. The other side 44 of the strip 4| is ink receptive, however, the barrier may be in the form of a coating applied to the paper or barrier material may be incorporated in the paper. The thermoplastic coating may desirably be paraflin wax as that is effective for the economical practice of the method and is also suitable in forming an adhesive bond with the wrapping paper. The ink used is desirably an ink which dries quite quickly and the drying of which is facilitated by heat. Suitable inks are commercially available.

At the rear of the printing cylinder and closely adjacent thereto is .a heating plate-45 this being supported at its rearend by the rod 46 and is provided with a plurality of electrical heating elements 41 arranged transversely therethrough.

0 The motor 24 is controlled by the switch desig- 55 to as it'leaves the printing cylinder. A guard 50 is arranged in advance of the heating plate to protect the printing cylinder from the heat and prevent setting or drying of the ink thereon. In passing over the heating plate or element the thermoplastic on the label strip is rendered adhesively plastic and the ink is dried or its drying facilitated. The heating element is controlled by the thermostat 41 I. The wiring for the heating element 41 and the thermostat is not shown. It is understood that the source of current can be connected with the wrapping machine or independent thereof. The fused thermoplastic serves as an effective heat conductor facilitating the quick drying of the ink and provides a uniform contact distribution of heat to the label strip.

While the thermoplastic adhesive is in adhesively plastic condition it is directed to and pressed upon the outer convolution of the roll of wrapping paper as is best shown in Figs. 1 and 3. The label strip or band is directed tangentially to the outer convolution of paper on the roll by means of the guide roller which is swingably supported on the arm 52 having a weight 53. This roller engages the printed side of the label strip and is desirably provided with peripheral longitudinally spaced ribs 54 which minimize any drag or scraper action on the printing. The label strip as is shown is guided substantially tangentially upon the outer convolution of the wrapper paper and is pressed thereon by the press roller 55 carried by the swinging arm 56. This results in an effective application of the label to the wrapping paper as it is unrolled from the roll 3. The label strip is pulled over the heating element by the web to which it is adhered. The roller 5| serves as a take-up and tensioning roller and compensates for irregularities of feed in the wrapping machine and. in the event that the withdrawal of paper from the roller is interrupted for a substantial period or pause, or in the event of the exhausting or breaking of the label strip 4|, the cam 65 on the arm 52 engages the switch control 66 and opens the switch 49 and thereby stops the motor 24. A stop 61 limits the rearward swing of the arm 52. I The practice of my method avoids the necessity of purchasing a large stock of pre-printed labels. I am aware that pre-printed labels have been applied to wrapping webs as the web is unwound from a roller in a wrapping operation. In my method I am able to completely print a label strip or band carrying a thermoplastic adhesive and immediately dry the ink and simultaneously plasticize the thermoplastic and apply the label or label strip as a continuous operation. The machine or apparatus of my invention as illustrated is very efficient for that purpose.

The printing plates may be readily changed and thereby quickly adapt the machine for different runs, for example one run might be XYZ buns are now sliced as indicated in the drawing and quickly changed as desired. To facilitate such manipulation the shaft l6 of the printing cylinder is provided with a hand wheel 5! to facilitate the manipulation of the cylinder in removing and applying the printing plates. The ink transfer roller 23 is carried by the arms 58 on the rock shaft 59 which is operated in timed relation with other driven parts by the chain of gears 60, the cams 6! and the connecting rod 62. These details, however, and the details of the ink roller reciprocating means designated generally by the numeral 63 are not illustrated or described in detail as they are known to the art. It is desired to point out that the spring 64 acts to yieldingly urge or bias the ink transfer roller 23 to the fountain roller 18.

I have described the steps of my method and one apparatus by which the same may be successfully practiced. I have not attempted to illustrate or describe various modifications and adaptations which I contemplate as it is believed that this disclosure will enable those skilled in the art to embody or adapt my invention as may be desired.

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