Abstract
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.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
199 words
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.
Claim 2
Dependent Claim
199 words
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.
Claim 3
Dependent Claim
75 words
A marking apparatus according to claim 1, including a housing vertically reciprocally supporting thereon said cutting punch and having a horizontal guide surface for supporting thereon the longitudinal portion of the adhesive tape, and a cutting anvil disposed between said cutting punch said support mandrel and having a vertical bore for the passage therethrough of said cutting punch, said cutting anvil having a downwardly sloped upper surface confronting said horizontal guide surface of said housing.
Claim 4
Dependent Claim
36 words
A marking apparatus according to claim 2, said housing having a pair of oblique guide grooves extending upwardly outwardly from opposite ends of said horizontal guide surface and disposed respectively in alignment with said guide rolls.
Claim 5
Dependent Claim
58 words
A marking apparatus according to claim 1, said cutting punch having a centrally recessed lower surface, said cutting edge being formed on an outer peripheral edge of said lower surface, said support mandrel having a substantially semi-spherical head cooperative with said recessed front surface of said cutting punch in holding therebetween the indicia and the defective slide fastener.
Claim 6
Dependent Claim
22 words
A marking apparatus according to claim 4, said cutting edge being of a circular shape and having a diametrically opposite recessed portions.
