A non-marking web conveyance roller has a generally irregular surface with a plurality of rounded up features that promotes superior venting of entrained air. The surface finish of the roller, formed by a thermal spray process, prevents the formation of impression and honing defects on the conveyed web.

Non-marking web conveyance roller

A corona discharge web conveyance roller ( ) and process for finishing the surface ( ) of the roller ( ) with plateaus ( ) and down features ( ) adjacent to the plateaus. Interconnected channels ( ) formed in the surface ( ) of the roller ( ) by overlapping down features ( ) comprise at least 50% of the surface area while plateaus ( ) comprise at least 20% to about 50% of the surface of the roller. Down features ( ) have depths greater than about 12 microns but less than about 125 microns.

Corona discharge treatment roller and surface finishing process

Process for finishing the surface of a corona discharge treatment roller

Apparatus and method for aligning webs, such as photographic film or paper, where the trailing edge of an expiring web is spliced to the lead edge of a fresh web. A supporting means having the fresh web thereon in a fixed position is caused to move by sensor means transmitting a signal corresponding to precise positioning of the expiring relative to the fixed position of the fresh web. According to the invention, a programmable controller is used to analyze the signals received from the sensors and directs the movements of the supporting means where the webs are ultimately moved into abutting or overlapping contact and then spliced.
