Abstract
775,407. Making slide fasteners. WALDES KOH-I-NOOR, Inc. Aug. 11, 1955 [Aug. 12, 1954], No. 23164/55. Class 83 (2). Apparatus for removing groups of fastener elements 11 at predetermined places from a continuous slide fastener chain which is fed intermittently beneath punches 14, has means 20, 33 which operate between successive feed movements of the chain for ensuring accurate location of each group or groups of elements to be removed relative to the punches. The chain is fed by intermittently rotating rollers 12, 13 and between each feed a locating pin 20 biased downwardly by a spring 21 is released by a cam 30 to engage between successive elements 11a, 11b, and a stretching pin 33 biased downwardly by a spring 39 is then released by a cam 38 and presses the chain between rollers 13, 40 to press the element 11a against the locating pin 20 and stretch the chain. Punch 15b is then actuated to remove a group of elements from adjacent the rear end of a length of chain to be cut off by punch 16, and a punch 15a is actuated to remove a group of elements from adjacent the forward end of the next length of chain. The pins 20,'33 are retracted by the cams 30, 38 which are driven in timed relationship with the punches. Specification 769,370 is referred to.
