ABSTRACT:
A hitch feeder for a TAB tape is described which comprises: a stationary jas assembly having opposing jaws for gripping edges of the tape when closed, and not gripping the edges when open; a movable gripping assembly which includes a lower movable gripper positioned below the tape and an upper movable gripper positioned above the tape. The lower and upper movable grippers may be moved both towards and away from the tape, each said movable gripper gripping the tape when moved towards it and releasing the tape when moved away from it. Both grippers are physically clear of any features on the tape when moved away from it. A tape feeder is provided for reciprocally moving the movable gripper assembly along the tape length, both towards and away from the stationary jaw assembly. A feed control is operative when the movable gripping assembly moves towards the stationary jaw assembly, to move the gripper jaws to grip the tape and to open the opposing jaws, and is further operative when the movable gripper assembly moves away from the stationary jaw assembly, to move the gripper jaws away from the tape and to close the opposing jaws.
