SU1391954A1 - Method of producing raised-pattern images on polymeric film for blind persons - Google Patents

Abstract

The invention relates to the field of printing and improves processability. Making relief-images on a polymer film involves laying the polymer film on a soft substrate, fixing it and exposing the film to a preheated embossing tool containing the working end and stop. The temperature for the onset of softening of the soft substrate is chosen 5–25 degrees higher than the ambient temperature, 2 s, n, f, ly, 2 sludge.

Description

This invention relates to the field of printing, in particular, to relief printing.

The aim of the invention is to improve manufacturability.

FIG. 1 shows a device for placing a polymer film; in fig. 2 - embossed tool on the polymer film,

The device contains the lower part 1, on which the soft bitumen 2 (or clay) is laid, the upper part 3 with windows 4, provided with notches 5, the body 6 of the embossing tool, the electric heating element 7, the rod 8 with the working end 9 and the limiter 10,

The polymer film is placed on soft bitumen 2, covered with the upper part 3 and the embossing tool preheated to the plasticization temperature of the film with the help of the working end 9 forms relief signs on the film.

Windows 4, made in the upper part, provide access for the embossing tool to the polymer film, and notches 5 facilitate the orientation of the working end 9 of the embossing tool during the production of element-wise embossing of embossed characters, for example, with Braille for the blind.

The electric heating element 7 is connected by means of electrical wires to any source of electrical energy, for example, to a car battery.

The stopper 10, located at the working end 9 of the embossing tool, prevents the film from being pierced and provides the same embossing depth.

For laying on the lower part 1, substances with significant adhesion (clay or soft bitumen) are used and with a softening onset temperature 5-25 degrees above the ambient temperature.
