Machines for feeding fabric sheets singly from a stack. Ply disengaging means float lightly with the top ply, as when the ply is indented by a pressing foot, and move laterally to disengage the ply and to nip the top ply. A cam actuatable pawl construction and a slide construction of pick up devices are shown. Rapid movements are shown to enhance the various steps in the cycle.
