Abstract

Transparency sheet stock for use in electrophotographic printing and copying applications having a ta ered and abraded lead edge or process edge is conventional means, for example, sanding, cutting, buffing, and the like, to create a tapered edge that is abraded and has a high coefficient of friction. The tapered and abraded edge provides several advantageous performance features: an increased coefficient of friction for the transparency sheet and reduced slippage in contact with fuser rolls; improved feeding angles of the transparency sheet into a fuser nip; a smoother and gradual separation of the fuser rolls allowing the transparency to enter the nip. This type of tapereaabraded edge may be placed on any transparency stock and is not noticeable to a customerhser. Alternatively, all four edges of the transparency sheet stock may be treated in the aforementioned manner thereby eliminating orientation problems. The tapered or V shaped transparency sheet edge provides for reliable feeding and prevents stalling in the pressure/fuser roll nip.
