Abstract
The invention relates to a form for the rotary machine printing, coating or imprinting of web-shaped materials and a method of producing the form wherein at a carrier having a cylindrical surface area an elastomer layer is attached which after curing at the outer circumference thereof is machined and engaged to result in a cylindrical shape. Furthermore the invention is characterized in that the elastomer layer is formed of a hot cure single-constituent or two-constituent silicone polymer.
