ABSTRACT:
A tape loader has a splicing station including a splicing block whose underside is grooved and provided with perforations constituting vacuum shoes. A slitting head mounts a blade which cooperates with the grooved under surface in slitting tape across its lateral dimension while it is received in its groove retained by vacuum. A splicing arm operates through an orifice in a face plate to splice together two lengths of tape retained in the groove. Operating on the front face of the face plate is a final guide assembly comprising an eccentric plate having a leader tape extraction arm; a bearing block housing a journal into which a cylindrical boss, integral with the plate, is rotatably received; and an internal flange of the boss forming a tooth wheel operably with a belt to apply the output of a motor to drive the plate. The changeover arm is comprised of a cranked changeover arm member mounted to a sleeve secured to a shaft passing through an orifice in the face plate. A clasp comprises a barrel received in a sleeve having a cylindrical type contact surface being provided by the barrel between annular enlargements. The tape issues in operation from a vacuum trough and is manually grasped by its end, disposed on the curved surface of the clasp and urged downwardly whereby through compression of the coil springs a quadrant surface is depressed radially inwardly.
