ABSTRACT:
An adjustable connection between a reciprocating rod and a rocker arm which is connected through a rotatable shaft to a linkage which shifts at least one feeding unit in a reciprocating feed stroke in response to movement of the rocker arm characterized by the rocker arm having a slot receiving a block which is pivotably attached to the end of the rod and which block is adjustably positioned in the slot to vary the effective length of the rocker arm and thus varies the length of the feeding stroke for the feeding unit. Preferably, the slot in the rocker arm lies on a line extending perpendicular to a longitudinal axis of the rod when the rocker arm is in one position so that one end of the feeding stroke of the feeding unit remains in a constant and fixed position relative to the device regardless of changes in the length of the stroke.
