Abstract
Official abstract text for this publication.
A method for production of a female embossing tool ( 6 ) intended for embossing a sheet element ( 60 ): provide a female embossing tool ( 6 ) with an outer layer ( 44 ) made of a material with shape-memory type properties, and the outer face of the layer has no recesses; provide a male embossing tool ( 5, 5 ′) with an outer face with at least one protuberance corresponding to at least one desired embossing relief that is to be formed on the sheet element ( 60 ) after embossing; and cooperation of the male embossing tool ( 5, 5 ′) with the female embossing tool ( 6 ) such that the outer layer ( 44 ) of the female embossing tool ( 6 ) undergoes a plastic deformation which creates at least one recess ( 42, 42 ′) of a shape complementary to the protuberance(s) ( 41, 41 ′) of the male embossing tool ( 5, 5 ′).
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for production of a female embossing tool configured to emboss a sheet element, the method comprising: providing a female embossing tool with an outer layer comprised of a material with shape-memory type properties, and the outer layer has an outer face having no recess; providing a male embossing tool, with an outer face which has at least one protuberance corresponding to at least one embossing relief on the sheet element after the sheet element is embossed; and moving the outer face of the female embossing tool and the outer face of the male embossing tool against each other for causing cooperation of the male embossing tool with the female embossing tool such that the outer layer of the female embossing tool undergoes a plastic deformation which creates at least one recess in the outer face of the female embossing tool, the recess of a shape complementary to the at least one protuberance of the male embossing tool. 2. A method according to claim 1 , wherein the material of the outer layer of the female embossing tool is at least one of a shape-memory metal alloy. 3. A method according to claim 1 , wherein the outer layer of the female embossing tool is a polymer material with shape-memory properties. 4. A method for production of a female embossing tool configured to emboss a sheet element, the method comprising: providing a female embossing tool with an outer layer comprised of a material with shape-memory type properties, the outer layer having an outer face including at least one recess, processing the outer face of the female embossing tool under selected conditions selected such that the outer face of the outer layer loses the at least one recess; providing a male embossing tool, with an outer face which has at least one protuberance corresponding to at least one embossing relief to be defined on the sheet element after embossing; and then moving the outer face of the female embossing tool and the outer face of the male embossing tool against each other for causing cooperation of the male embossing tool with the female embossing tool such that the outer layer of the female embossing tool undergoes a plastic deformation which creates at least one recess of a shape complementary to the at least one protuberance of the male embossing tool. 5. A method according to claim 4 , wherein the material of the outer layer of the female embossing tool is at least one of a shape-memory metal alloys. 6. A method according to claim 4 , wherein the outer layer of the female embossing tool is a polymer material with shape-memory properties.
