发明名称 Paddle wheel retard feeder
摘要 An apparatus for feeding individual substrates from the top of a stack of substrates upon demand includes a first paddle wheel mounted above the substrate stack and adapted to forward a substrate from the stack in a predetermined direction and a second paddle wheel downstream from the first paddle wheel that is adapted to continue movement of the substrate in the predetermined direction. A friction retard roller is positioned opposite to and forms a nip with the second paddle wheel in order to inhibit multi-feeding of substrates. A second embodiment includes a single paddle wheel that acts in combination with a high friction surfaced guide member to feed substrates individually from a stack.
