The invention relates to the process of roducing impressions in the form of la ls, bands or other indicia, embodying a meta-llized medium and usually one or more colors Y 5 on a web or individual strips of cellophane or other material, such as cellulose acetate paper, glassine paper, etc.

The invention is particularly adapted to cellophane in web form or individual predetermined lengths, for enclosing cigars, 1n which instance of use the impression applied to the cellophane pursuant to my process may simulate a so-called cigar band, such indicia when applied to the web being spaced in proper relation to one another and in proper relation to the edges of the cellophane strlp, whereby severed individual lengths are adaptable to be fed to present day machines for enclosing individual cigars in so-called pockets of the cellophane material. However, my invention is not limited -tosuch specific applications and may .be utilized for ap lying indicia of any desired character em odying a metallized medium.

Pursuant to my invention, the web of cellophane or other enclosing materlal 1s 1mpressed with indicia at definite spacing from one another and with respect to the edges of the web, the indicia embodying an impression including a met-allized medium and usually one orV more colors. The desired color or colors are 'preferably applied by individual printing rolls correspondmg to the number of the desired colors, which color impressions may be effected either before or after, or both before and after the step of applying the metallized medium.

The metallized medium is preferably applied by the use of a rotary roll, suitably driven, adapted to carry a die or set of dies, under proper temperature control, to which dies are applied in sequence a regulated film of waxy or equivalent material, on which is imposed a regulated layer of the metallizing mediumpr media, whereby the desired indicia are impressed upon the web at the desired b spacings relative to one another and relative to the'edges of the web. If desired, the ini0 dicia may be wholly or in part embossed, the

embossin operation being carried out preferably susequent to the metallizing step.

Further features and objects of the invention will be more fully understood from the following detail description and the accompany drawings, in which Fig. 1 is a plan view of a fragment of a strip bearin an indiciain the form of a band applicable or enclosing cigars. The indicated dimensions of the strip and the relative location of the band are ap licable to a strip length for forming a, so-ca led pocket for individual cigars. l

Fig. 7 is a top plan view of a portion of the 85 mechanism for applying metallized impressions..

Referring' to Figs. 1 and 2, the cellophane or other material isl indicated at 10, the indicated dimensions of the sheet 4corresponding 90 to that of a severed length cut from a web. The indicia 11 in this instance is in similitude of a cigar band by reason of the article to be enclosed being a cigar, the impression band being disposed at proper spacing from the opposite edges 12, 13 andl 14, 15, the edge 12 elng proximate the butt end of the cigar,'the edge 13 being proximate the point of the cigar, the edges 14, 415 being folded in overlapping relation to one another at the back 30 serving to supply of the cigar, it being understood that the ends of the resulting pocket are folded upon one another to provide for full or substantially full sealing of the pocket, with or without the use of sealing or other adhesive.

In the particular indicia 11, shown in the form as simulating a band, the metallic medium, which may be genuine or imitation gold, genuine silver or its imitation, or other desired metallic medium as indicated at 16. This particular indicia may also include two colors, say red and black, as at 17 and 18.

The colors such as 17 and 18, of any desired number and desired locations, are applied to the material either before or after the application of the metallic 'medium or media.

Fig. 3 shows in diagrammatic cross-section, the cellophane at 10, the undermost layer of sizing, such as shellac at 18, the superposed metallic medium, such as bronze, at 19, and the outermost layer, such as wax or other suitable unctuous material, at 20. In such instance the layer 18 serves as the initial bonding medium, the bronze or other metallic medium being superposed upon the same.

As appears more fully hereinafter, the indicia bears suitable trade or other name or names effected by means of suitable dies or sets of dies, the dies being heated to proper elevated temperature afforded by means of an electrical resistance unit or other suitable controlled heating means.

Fig. 4 corresponds to Fig. 3, except that the initial bonding layer 18 is omitted, the bonding of the metallic medium 19 and superposed wax medium 20 being effected directly upon the material. Like parts are indicated by like reference numbers.

I have illustrated in Fig. 5 in diagrammatic form, one manner of applying the metallic medium or media to a web of cellophane or other enclosing material. v

At 21 is indicated a supply roll, the web 22 of which is passed through the indicated guiding and operating parts and rewound if desired in the form of a roll as indicated at The dies 24, orv set of such dies, are mounted on a suitable printing roll 25, the shaft 26 of which is suitably driven in the direction of the indicated arrow 27. At 28 is represented a bath 29 of suitable waxy or other unctuous composition, kept fluid by suitable heating means (not shown), the roll the waxy material from the bath 29 to the face of a die 24 when in engagement with the supply roll 30.v At 31 I indicate a wiping roll and at 32 a doctor in the form of a wiping plate, whereby to regulate the film upon the effective surface of the supply roll 30, rotated in the direction of the indicated arrow 33.

It will be understood that the individual dies 24 or the p1 inting roll 25 itself may be suitably heated to the proper temperature, as by means of electrical resistance, referred t0 l hereinafter, whereby the film of the unctuous material supplied to the face of each die during the stage of engagement by the supply roll 30 is maintained in proper condition for the'completion of the operation.

At 34 is diagrammatically indicated a suitable bronzing machine or equivalent for su plying bronze or other desired metallic me ium applied to the die as a layer superimposed upon the waxy composition. In this instance I have indicated at 35 the use of a single lnetallizing medium, such as bronze, contained in the hopper 36, at the discharge end of which is disposed a supply brush 37 suitably rotated in the direction of the indicated arrow 38. At 39 is represented suitable means for removing any excess of metallic medium and diagrammatically illustrated as comprising the wiping brush 40 disposed at the mlet opening of the conduit 41 provided with the indicated exhaust fan 42, the recovered metallic medium being collected through the discharge outlet 43.

The pairs of rolls 44, 44, and 45, 45, serve as guide rolls, one or both of which may be directly driven to serve as feeding rolls, the pair of rolls 45, 45, being preferably arranged to act as pull rolls.

Coacting with the printing roll 25 is arranged animpression roll 46, driven -in the direction of the applied arrow, having a surface of leather, paper, or other suitable resilient material, thereby to derive impressions corresponding to the outlines of the dies 24.

At 47 I have indicated a wiping roll rotated in the direction of the indicated arrow to clean the dies 24 after each impression operation, the removed material being recovered through the exhaust conduit 47 Accordingly, u on contact of the one or more dies 24 carried by the printing roll 25 with the face of the web 22, the metallized medium is deposited and bonded to the web face in correspondence to the outlines of the configuration of the die faces, that is to say, with the lettering, wording, symbols, inner and outer outlines, etc., of the respective dies ortions, as may be desired.

W ere an initial bonding Amedium is desired or required, such bonding medium may be applied by the use of a roll 50 driven 1n the direction of the' indicated arrow, and provided with a protuberance 51 corresponding at its effective face to each die 24, the desired initial bonding medium, such as shellac -or other sizing, etc., being provided by means of a receptacle 52 and a supply roll 53, driven in the direction of the indicated arrow, whereby such sizing or other initial bonding material is applied upon the face of the web in advance of and in proper register with the subsequently app ied metallic impression. The roll 54 coacts with the protuberance 51 of the\roll 50 in the nature of an impression roll.

I have iplso indica-ted at 78 suitable means for applying the sizing or other adhesive, in lieu ofthe roll 50, the sizing in this instance being applied upon the met-allie medium on each die. The film of the adhesive thus applied is supplied by the roll 79, driven 1n the indicated directlon and provided with a be effected by ilmre ulting roll and doctor, similarly as in tefapplicationof the waxy film.

If desired, the unit 51 may apply a medium serving to soften lor otherwise prepare the surface of the web for the reception of the impressed material and unit 78 may supply a protective medium such as cellulose acetate.

In many instances it is desirable to emboss the applied metallic impression, which ma the use of the embossing ro l 5 5 indicated as disposed subsequent to the ing a plurality of colors printing roll 25; the roll 55 is provided with y an embossing protuberance 56 .and is driven in the direction of the indicated arrow 57.

The roll has a cooperating impression roll 58, effective spacing of the em ossing protuberance 56 being regulated to register with the whole or a part of the metallic or other 1m ression desired to be embossed.
