An apparatus (10) for assembling a pair of fastener elements (A, B), comprises a first drive mechanism (16) for driving a punch assembly (13), and a second drive mechanism (17) operatively connected with a pair of parts feeders (18, 19) to drive them in timed relation to the movement of the punch assembly (13). The second drive mechanism (17) is so constructed as to exert a driving force smaller than the driving force exerted by the first driving mechanism (16) to such an extent as to become halt when the fastener elements (A, B) are jammed in either parts feeder (18, 19). Thus, the jammed parts feeder (18, 19) is free from any damage which would be caused when the parts feeder is forcibly operated under such jamming condition. |
