Abstract
The invention relates to a form for the rotary printing, coating or imprinting of web-shaped materials and a method of producing the form wherein an elastomer layer is applied onto a carrier with a cylindrical surface area with the layer machined and engraved at the outer circumference to result in a cylindrical shape after curing. The form according to the invention is characterized in that the elastomer layer is formed of cold cure material. The engraving of the elastomer layer preferably is attained by laser engraving.
Claims26
A form for printing, coating and imprinting, the form comprising:
- a carrier having a cylindrical outer surface, the cylindrical outer surface being coated with an elastomer layer, the elastomer layer having a cured outer surface that is machined and engraved, the cured outer surface of the elastomer layer having a cylindrical shape, the elastomer layer comprising a cold cure material comprising a material selected from the group consisting of a single-constituent silicone polymer, a two-constituent silicone polymer and a mixture of a single-constituent silicone polymer and a two-constituent silicone polymer, and wherein the engraved outer surface is generated by laser engraving.
A method of manufacturing a form for printing, coating and imprinting, the method comprising the following steps:
- providing a carrier having a cylindrical outer surface,
- coating the cylindrical outer surface of the carrier with an elastomer layer comprising a cold cure material comprising a material selected from the group consisting of a single-constituent silicone polymer, a two-constituent silicone polymer and a mixture of a single-constituent silicone polymer and a two-constituent silicone polymer,
- curing the outer surface of the elastomer layer,
- machining the outer surface of the elastomer layer, and
- laser engraving the outer surface of the elastomer layer.
A method of manufacturing a form for printing, coating and imprinting, the method comprising the following steps:
- providing a carrier having a cylindrical outer surface,
- rotating the carrier,
