ABSTRACT:
An automatic pull tab insertion unit of an insert molding machine can automatically insert a plurality of metal pull tab members fitted to respective sliders of slide fasteners into the insert molding machine in order to form a synthetic resin grip integral with each of the pull tab members. The pull tab insertion unit has a pull tab insertion member for inserting a plurality of pull tab members fitted to respective sliders into the insert molding machine, while holding the sliders, and a positioning member for causing the pull tab insertion device to hold the sliders with the respective pull tab members by pushing the sliders against the pull tab insertion member and positioning the pull tab members. The pull tab insertion member and the positioning device are arranged perpendicularly with each other and adapted to be vertically moved together by a lift-device and pivoted by 90.degree. between a horizontal plane and a vertical plane by a pivoting device. The pull tab insertion member and the positioning member have respective actuation members independently movable to and from the point of intersection and independent actuators for driving the respective actuation members to move in directions to intersect.
