Abstract
A forming roller for manufacturing molded bodies with the rotary die method comprises a surface which is roughened at least in the region of the forming roller webs. By way of the roughening of the forming roller webs the adhesive friction for the material tapes from which the molded bodies are manufactured is increased. The roughness of the surface parts of the forming roller is advantageously produced by the processing of the surface with a blast means.
Claims14
A forming roller for a machine for manufacturing moulded bodies, in particular gelatine capsules with the rotary-die method, with a surface which is provided with a multitude of deepenings with an inner surface for receiving the moulded body to be manufactured, wherein the deepenings are each surrounded by a web projecting beyond the surface and wherein the surface at least in the region of the webs is at least partly roughened.
A method for processing forming rollers for a machine for manufacturing moulded bodies with the rotary-die method, wherein the coating surface of the forming roller is at least partly subjected to a treatment with a granular blast means and thereby is roughened.
