A cupfeeder for feeding cups from a supply chute to a feed location in operative alignment with a drawing and ironing machine is disclosed. The cupfeeding mechanism comprises a push rod mechanism mechanically driven in reciprocating strokes to advance a cup which has dropped from the lower end of the chute to the feed location along a transfer path defined by a positioning member. The push rod mechanism includes an inner push rod extending telescopically from an outer push rod driven by the reciprocating drive. The inner push rod is maintained by pressurized fluid in a fixed axial location, relative to the outer push rod, to project forwardly therefrom to a maximum extent to engage the cups in the cupfeeding process. In response to jamming of a cup within the drawing and ironing station, pressurized fluid is re-routed within the outer push rod to retract the inner push rod and prevent further transfer of cups along the transfer path. The cupfeeder also includes a cylinder actuated stop adapted to enter the transfer path in response to said jamming. A further stop arrangement may be provided within the chute to prevent a next in-line cup from dropping through the chute into the transfer path.
