ABSTRACT:
A gripper device which is a part of a slide-fastener finishing apparatus and which is used to grip and take out completed fasteners successively by grippers reciprocally moved along the fastener flow direction.
The improvement comprises placing a driven belt-like member in an endless fashion over two rotation wheels, the wheels being positioned on an extended line of fastener flow at predetermined intervals, mounting two gripper-equipped members on the belt-like member at equal intervals, each gripper equipped member including a gripper which is movably mounted so as to be able to align with the center of the completed fastener outlet port, moving each gripper-equipped member to the completed fastener outlet port by rotating the rotation wheels in forward and reverse directions, and then gripping and taking out the completed fasteners with each gripper.
The gripper device according to the invention enables the efficiency of taking out completed fasteners to be improved, and the continuous finishing process of fasteners to be speeded up.
