ABSTRACT:
A scuff separating device capable of feeding difficult to separate sheets from the outside of a stack includes a feed belt or roller for contacting the outside sheet and feeding it off the stack. A retard roller is supported by a support arm pivoted about a pivot downstream, and rests on the feed belt or roller and prevents double feeds. A brake on the retard roller prevents rotation when more than one sheet is in the nip but permits rotation when one or no sheets are in the nip.
