Abstract
A roller for transport and/or guidance of flexible webs or sheets of radiation-sensitive material has a grounded shaft and an antistatic cylindrical member which is coaxial with and surrounds the shaft and has a web- or sheet-contacting cylindrical peripheral surface. The cylindrical member consists of hard polyvinyl chloride, fine crystalline polyamide, polypropylene, polyethylene or a mixture of two or more such plastic materials. Pulverized silver or another pulverulent metal is embedded in the material of the cylindrical member. If the roller is rather long, the cylindrical member surrounds a hollow cylindrical metallic core whose end portions confine inserts which surround the respective end portions of the shaft.
