ABSTRACT:
A strip-feed mechanism employing hold and feed gripper blades has a horizontal drive shaft with an adjustable eccentric assembly on it projecting from one side of a frame for easy access and adjustment. To accommodate extremely thin sheet material, the hold gripper blade is lifted from the sheet material during the forward portion of the stroke. The adjustable eccentric includes a cylindrical portion eccentrically mounted on a drive shaft and having a threaded periphery threadedly engaging an internally threaded wall of a bore through a cam member. The cam member and the threaded portion of the drive means are clamped together by a fastening means including a threaded plug and bolts. The threaded plug is threadedly received in the bore in the cam member, and the bolts are received in tapped holes in the cylindrical portion and bear against the plug to stress the mating threads on the drive member and cam member.
