Embossing die

Abstract

In a method for the manufacture of an embossing due for the cold and hot embossing of paper and cardboard a plane material impregnated with a duroplastic resin is brought into close contact with a shaping die, both are pressed together to obtain a press die from a plane material impregnated with duroplastic resin after hardening of the materials brought into contact with each other.

Description

Claims

1. A method for manufacturing an embossing die for the cold and hot embossing of paper and cardboard, comprising bringing a plane material impregnated with a duroplastic resin into close contact with a shaping die and pressing together the plane material impregnated with a duroplastic resin with the shaping die to obtain an embossing die from said plane material impregnated with duroplastic resin.

2. The method according to claim 1, wherein the plane material impregnated with duroplastic resin is formed in a press with thermostatically controllable press dies.

3. The method according to claim 2 wherein the shaping die having two press dies and wherein at least one of said press dies is heated to a temperature of 80 to 200° C. to form the plane material impregnated with duroplastic resin.

4. The method according to claim 1, wherein the plane material impregnated with duroplastic resin is formed and cured by energy-rich radiation, in particular UV radiation.

5. The method according to claim 1, wherein the shaping die is provided with a release film before the introduction of the plane material impregnated with duroplastic resin.

6. The method according to claim 1, wherein the plane material impregnated with duroplastic resin is placed for shaping above the shaping die.
