Abstract

A low friction retard feeder system 1 for use with a copy sheet paper feeder in an electrostatographic copier includes a belt 2 having a multiplicity of sections with different coefficients of friction. The system includes a retard roller 3 which forms a nip with the belt 2 through which copy sheets 4 are driven on their way to the transfer station of the copier. The retard roller 3 includes a multiplicity of sections having different coefficients of friction which complement the sections on the feed belt 2, being positioned so that one section on the belt when in contact with the roller is in contact with a section on the roller that is different than that on the belt.

LOW FRICTION RETARD FEEDER (Cont'd)

A low friction retard feeder system 1 for use with a copy sheet paper feeder in an electrostatographic copier includes a belt 2 having a multiplicity of sections with different coefficients of friction. The system includes a retard roller 3 which forms a nip with the belt 2 through which copy sheets 4 are driven on their way to the transfer station of the copier. The retard roller 3 includes a multiplicity of sections having different coefficients of friction which complement the sections on the feed belt 2, being positioned so that one section on the belt when in contact with the roller is in contact with a section on the roller that is different than that on the belt.

In operation, the belt 2 positioned over the stack of sheets 4 causes the top sheet to be pulled toward the throat between the roller 3 and the belt 2 with the retard roller being very close to the front edge of the stack, the separated sheets are immediately subjected to the queing operation of the throat. The alternate and oppositely matched sections of high and low friction coefficient materials improves the useful life and reliability of the feeding system by diminishing feeder failure due to contamination from paper dust and other foreign substances.
