APPARATUS FOR INSPECTING THE ATTACHED STATE OF SLIDE FASTENER STOP BOXES, AND STOP BOXES ATTACHING MACHINE EQUIPPED WITH THE SAME

摘要

An apparatus for continuously inspecting the attached states of successive bottom stop boxes attached to separable slide fasteners, comprises a pair of tape grip members movable forwardly and backwardly along a travelling path of a fastener tape to which the individual bottom stop box is attached. The tape grip members are situtated upwardly and downwardly of the fastener tape travelling path in confronting relationship, each of which being pivotally movable about the horizontal axis extending through its central portion. The tape grip members have urging means for normally urging their upstream ends toward each other, and forced turning means for forcedly turning their downstream ends toward and away from each other. The apparatus further comprises a moving body situated on one side of the grip members for moving forwardly and backwardly together with the grip members, a contact member situated in a fixed position in a path of movement of the moving body and normally urged toward the moving body by a predetermined resilience, and detecting means for detecting an amount of movement of the grip members when the moving body is moved to a predetermined length against the predetermined resilience in contact with the contact member.
