Abstract
A marking apparatus is disclosed for cutting a piece out of an adhesive tape and simultaneously attaching the same onto and individual slide fastener which has been found defective during the travel of a continuous slide fastener chain. The apparatus is operatively associated with a detecting device which controls the operation of an air cylinder so that a cutting punch is reciprocated toward and away from an anvil and a support mandrel.
Claims5
A marking apparatus for identifying defective slide fasteners in a continuous slide fastener chain as the slide fastener is fed longitudinally along a horizontal path, comprising:
- (a) means for detecting a defective slide fastener in the slide fastener chain;
- (b) a punch operating unit actuated when a defective slide fastener is detected by said detecting means;
- (c) a cutting punch driven by said punch operating unit to reciprocate along a vertical path, said cutting punch having a peripheral cutting edge;
- (d) at least two guide rolls disposed on opposite sides of said vertical path of movement of said cutting punch for supporting therebetween a longitudinal portion of a continuous adhesive tape, said cutting punch when driven being operative to cut a piece out of the longitudinal portion of the adhesive tape, thereby producing an indicia indicative of a defective slide fastener;
- and
- (e) a stationary support mandrel disposed below said horizontal path of movement of the fastener chain in registry with said cutting punch for supporting said indicia between the detected defective slide fastener and said cutting punch, said support mandrel having a relieved upper surface held out of contact with said cutting edge when said indicia is supported.
