"Method and equipment for the continuous production of self-adhesive Siebarucli labels"

G O O O ü O

The invention relates to a method and apparatus for the continuous manufacture or multi-colored self-adhesive screen-printed labels. The self-adhesive labels, in most cases made of canvas or other fabrics, find a widespread one Application in the field of confectionery, in the manufacture of footwear, as well as in other areas.

These labels often have single or multi-colored lettering or symbols that can be printed directly of the label material. The self-adhesive labels are still present produced by a lengthy process and consequently at high production costs.

The main end purpose of the invention is to provide a method and apparatus for continuous, easy and economical production of self-adhesive labels for use where im Screen printing process single or multi-colored lettering or symbols are printed on.

jSin other purpose is to put silk-screen printed labels on a tape to be wound continuously on a reel receive the labels from the sicti as required can be easily detached.

The purposes mentioned, along with others, will be achieved by means of a method according to which from a feeder roller a laminated tape pad, which is usually made of paper, with a self-adhesive sand, is included mostly a fabric, unwound to form the labels is, with the laminated sand at intermittent ! Movement glides step by step over a support where during the pause in an or the colored symbols or labels are printed on several stations using the screen printing process, then punching scissors just punch out the self-adhesive labels along their contours, and so that The laminated and punched tape is wound onto two collecting spools, with one spool being the tape support with the printed and die-cut self-adhesive Contains labels, while the other reel only picks up the contour offcuts, which are Separate from the tape support by pulling gently; the tape laminated in this way forms just above the spool an indentation to which the tape is intermittently

The invention is preferred with reference to the accompanying drawings by the following description of a The form of the specification is easier to understand. It brings:

- Fig.l is a schematic representation of an apparatus for the continuous production of self-adhesive labels printed using the screen printing process;

- Fig.2 shows a detail of the apparatus on a larger scale; and

- Fig.3 in plan is a piece of the continuous Support tape with the self-adhesive printed with the apparatus according to Fig. 1 and 2 in the screen printing process Labels.

Kann'man from Figure 1 seen in particular that for making labels selbstanhaftender a Spei serrolle one and two take-up reels 2 and 3 apply. The unwinding roll 1 is formed by a layer _{tape 5 known per se 9} which is obtained by coupling a support tape 7 made of paper or silicone paper ^ as well as a tape made of plastic material and the like and is laminated with a self-adhesive tape and thus preferably on self-adhesive tape for the production of labels Tissue contributes

The layer tape 5 unwinding from the reel 1 lies over the supports 4 »goes between the arms 12 of one known in and of itself Pliers, which are connected to a mechanism, whereby the intermittent feed in the Direction of the arrow above said arms 12 takes place.

Above the support surface 4, namely above the arms of the belt driving tongs 12, there is a series of machines (8,9) intended for single-color screen printing processes, follow the means 10 for drying the prints just made. These fascines for screen printing are automatically controlled and take the impression only during the stopping stages of the bando. While the machine 8 carries out the monochrome print on the stationary belt, the machine sits down (and so all of them) from the belt as soon as the belt is pulled a little further by the driving pliers. In the subsequent pause in which the belt stops, the machine 9 lowers in relation to the same Machine 8 printed zone and automatically makes a new impression in a different color. Of course, several screen printing masks can be used.

can be used, depending on the number of colors.

Underneath the last screen printing machine 9 for single-color printing, there are punching scissors 11, also of a known type, which sit on the laminated tape printed in the screen printing process and only punch out the printed fabric, but not the paper overlay 7i below, a specific embodiment, this one Stansschere is in the Italian patent application Ev. 22021 A / 73. The punching scissors 11 are also connected to the belt drive pliers by means of a Kinenatisirus, which can be easily carried out by any person skilled in the industry and therefore not further described here for the sake of simplicity, namely in the manner that the punching scissors only sit down and press on during the stopping stages.

It is also readily apparent that the screen printing machines or the punching scissors are aligned so that the subsequent printing operations in the The same bandsone of the label are carried out and so are the cutouts along the label contour takes place.

Underneath the support surface 4 and the belt drive pliers a free ICornpens .: uion room 13 is provided, to which the already printed, laminated tape with the punched out contours of the labels is fed intermittently will.

In this compensation space "the sag of the Laminated tape an elongated bulge 14 in the direction of the tape outlet, v / o the tape two rotating Separating rollers runs through and divided into two separate tapes, so also wound on two separate spools will.

Specifically stated, the tape 6 formed by the paper base 7 is wound on a spool with the adhering printed and punched, ready-to-use self-adhesive labels 15 on: one piece of the band 6 is indicated in Figure 3 in plan. The running tape of the contour offcuts of the self-adhesive is wound on the other reel Labels 15 on: this tape resembles a chain of label contours on the paper backing remained adherent.

The task of the compensation space 15 is to allow the coils 2 and 3 to rotate continuously, while the band 5 is taken along by the pliers 12 advance wakeful.

The compensation space is also important because because the circumferential speeds of the bobbins 2 and the bobbin diameter increases with the increase. Preferably the Kompensatxonsraum has photocells 16 and 17j, which stop the rotation of bobbins 2 and 3 or restart it as soon as the Arch part 14 in the mentioned space catches the light rays of the photocells or not: after a stop of the coils 2 and 3 automatically resumes their rotation as soon as a sufficient tape length has been reached. The illustration shows the detail of the Apparatus relating to the feeder coils. The feed reel 1 of the laminated tape 5 is on two opposing conically grooved mandrels 18 Zen-Irish mounted, their shaft in a stand 19 is rotatably mounted to be rotated by a motor 20.

The motor 20 takes care of the unwinding of the tape 5 in such a way that it forms a free slack 21 opposite a photocell 22. The photocell 22 controls the power supply to the motor 20 and switches it off as soon as there is an excessive length of tape 5, and starts it again if necessary

its slack is starting to get excessively small. Thanks to this take-up, the pliers only need 12 to pull the tape lying on the support 4 forward without having to act on the reel 1? It turned out to be particularly useful for extremely precise screen printing and punching above the Provide printing press sliding jaws 23, which on the Apply light pressure to the band 5 lying on the support 4 a spring 24 adjustable with button 25 is determined. In this way, a constant tension value is achieved in the strip.

In conclusion, both the method and the apparatus prove to be perfectly suitable to carry out multi-color screen printing on self-adhesive labels automatically, quickly and economically, especially also punching out with a half-deep incision, alternating advancement of the tape and rewinding of the printed, punched out and offcuts separate tape is involved.
