Abstract

SUMMARY OF THE INVENTION: the device comprises sequentially fixed on the base the holder of the feeding reel and the mechanism of cutting the tape, including the supporting surface for the tape, made in the form of a comb, and a cutting tool, which is a drum from a set of segments mounted under the comb for rotation. The drum has rigidly fixed between adjacent adjacent segments of the cutting elements mounted with the possibility of free passage between the corresponding teeth of the comb. 3 ill.

Description

The invention relates to the manufacture of articles made of impregnated adhesive roll material or tape and can be used in the printing and other industries both for the manufacture of articles made of impregnated fabrics and for fixing other products by means of adhesive roll material.

The purpose of the invention is to reduce the consumption of adhesive tape.

. New in relation to the prototype is the implementation of the mechanism of cutting the tape in the form of a drum segments of the chord, between which the cutting elements are mounted rigidly mounted with the possibility of free rotation together with the drum. In addition, the introduction of a comb into the device, between the teeth of which the corresponding cutting elements freely pass, is also new;

The device, due to the original design of the cut mechanism, provides uniform force over the entire cut area and ensures a smooth edge without the adhesive leaving the tape. This is especially important in the process of preparing printing forms and in photocomposition processes, as transparencies in the process are fixed on a transparent film like Astrolon. Her knowledge and contact. surfaces that rub with it during operation are unacceptable.

In addition, the device has the ability to readjust to the desired size. You can firmly withstand both the size of the cut-off segments and their number.

Thus, a new technical property of the device is that the design of the device ensures the movement of the cutting tool relative to the tape during cutting with the distribution of uniform force in the cut-off areas, i.e. the degree of deformation of the tape at the point of separation is reduced.

A positive effect is achieved by the combination of all the features, but the goal (reducing the consumption of adhesive tape) is achieved by implementing the mechanism of cutting the tape in the form of a drum of segments mounted for rotation, and cutting elements are rigidly fixed between adjacent segments.

In FIG. 1 shows the proposed device; in FIG. 2 - the same, top view; in FIG. 3 is a section AA in FIG. 1.

The device for dispensing adhesive tape consists of a base 1 on which racks 2 of the holder of the supply reel 3 and racks 4 of the tape cutting mechanism are mounted.

.In comparison with the prototype, the device has the following technical advantages. Firstly, it provides a smooth cut edge without deformation of the film and without the adhesive leaving the tape, which is especially important in printing. In addition, despite the use of a sharp cutting element, the device is quite safe and very convenient to use.

Using the device will at least reduce the consumption of adhesive tape compared with the prototype in 2 times.
