A device is powered for movement heightwise and laterally of a pile of work pieces, for instance articles of fabric or the like, and includes fluid pressure operated jaws for seizing and releasing successive single work pieces. The jaws are operative adjacent to a suctional opening in a work transferring member that contains a fluidically controlled circuit responsive to the change in pressure in the member, when its opening is restricted by a work piece, to effect closure of the jaws thereon. Arrival of the member with its clamped work piece at the release position causes the circuit to release the work piece.
