Title: Paper feeding and carrying roll
Inventor: KOJIMA TAKASHI
IPC: B65H3/06
Filed: 1995-12-11
Abstract: PROBLEM TO BE SOLVED: To keep a stable frictional coefficient without being influenced by paper powder and significantly simplify forming process by providing a crimp pattern having a specified surface roughness on the surface of a paper feeding and carrying roll used for the feeding or carrying of paper sheets. SOLUTION: This paper feeding and carrying roll used for feeding or carrying of paper sheets has a crimp pattern having a surface roughness Ra of 10μm-150μm on the surface. The paper feeding and carrying roll can be manufactured by use of a material selected from various rubber materials and thermoplastic elastomers. Since it has the crimp pattern by crimping on the roll surface, paper powder adhered to the surface is fitted into the recessed parts of the crimp pattern, whereby the reduction in frictional coefficient by the paper powder can be suppressed similarly to a conventional polished surface. The crimp pattern of the paper feeding and carrying roll can be formed simultaneously with press molding by performing the press molding, for example, by use of a metal mold for forming the crimp pattern on the formed surface.
