ABSTRACT:
A gripper mechanism for feeding a pair of elongate strips such as a pair of slide fastener stringers has a pair of gripper holders supporting a pair of grippers for gripping the slide fastener stringers, respectively, and a pair of sliders joined to the gripper holders, respectively, and slidably disposed in a housing for independent movement therein. In response to engagement with a cam on a feed path, the grippers are opened to grip or release the slide fastener stringers. The grippers are normally urged by a spring to clamp the slide fastener stringers. A pinion is angularly movably supported on a slide block in the housing and held in mesh with a pair of racks, respectively, of the sliders. A spring acts between the housing and the slide block for normally urging the slide block in a direction to move the gripper holders into abutment against the housing. The gripper holders can be moved relatively to each other toward and away from the housing.
