Abstract: In the present cam-driven intermittent movement for motion picture machines the pull-down action is shared by a plurality of cams mounted on a common shaft and operating in tandem, thereby reducing the noise and vibration and/or permitting faster pulldown. One cam drives a claw arm in its swinging movement about a pivot, while the other cam drives a carrier arm which is pivoted at one end on the machine frame and carries at its other end the claw arm pivot. Meshing action of the claw may be controlled by cam action applied to either arm. Such action may be derived from the same cam as the pull-down action, or may employ an auxiliary meshing cam.

Abstract: A hitch feed assembly for automatically aligning individual lead frames at a bonding site in both the longitudinal and lateral directions is disclosed. The alignment is attained as a result of the cooperation between a plurality of chamfered pawls and the sprocket holes in the film-carrier. The pawls are chamfered along three sides in order to attain alignment in both the longitudinal and lateral directions. Significantly, the pawls come into operational contact with the sprocket holes while the lead frame film-carrier is under minimal tension so that the pressure exerted on the edges of the sprocket holes by the pawls will be minimal, thereby avoiding any deformation in the shape of the sprocket holes.
