A document separation device for separating documents in a stack employs counter-rotating feed drum and friction belt members to strip away and hold back more than a single document trying to pass between them. The structure employs a pair of stripper idlers mounted for free-wheeling rotation adjacent the feed drum. The stripper idlers are constructed and arranged so as to be controlled by the documents passing between them and the adjacent feed drum so as to automatically speed up or slow down when required. The stripper idlers are designed to maintain the proper force against the drum or a document passing therebetween to feed the documents in the desired path through the apparatus and to straighten out severely curled leading edges of the documents to avoid jamming, tearing or skewing of the documents. In addition, the idler strippers serve to fan out the documents to hold them in a desirable condition for ease of separation.
