ABSTRACT:
A printed sheet transfer assembly for supporting and carrying sheets from one station in a printer apparatus to another station includes a transfer structure including a sheet conveying surface, and a flexible resilient material secured tightly over the conveying surface and having several ridges for engaging and conveying the sheets and for cushioning the sheets to prevent marring of printing ink. The material may include an ultra-soft cotton fabric. The conveying surface includes a matte finish. The transfer structure is optionally a transfer cylinder. The material may be secured over the conveying surface with hook and loop fasteners. A method of preparing a printing press transfer structure having a sheet conveying surface for transferring printed sheets from one station of a printer apparatus to another station includes the steps of covering at least part of the conveying surface with yielding ridged material, and tightening the material over the conveying surface to a tension level sufficient to take up slack in the material but insufficient to pull out the ridges. The method may additionally include the step of creating a matt finish on the conveying surface to cause the conveying surface to more securely hold the material against motion relative to the conveying surface.
