Abstract

Abstract A method for applying small prefabricated stop members and drawing sliding clasps onto sliding-clasp fastener tapes comprising attaching two upper stop members and one lower stop member at top and bottom ends of an engaged fastener tape, the lower member fitting over the engaged teeth of the top and providing a lower stop for the travel of the clasp, while the upper stop members are fitted in outwardly splayed fashion with the divergent ends in the direction of the tape advance so that the moving clasp can back over these members in traveling toward the lower stop member.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 173 words
A method for assembling small prefabricated stop members and for drawing sliding clasps onto engaged sliding-clasp fastener tapes, these fastener tapes comprising tape parts held together by rows of teeth, the method comprising the steps of: a. continuously advancing fastener tapes which are interengaged by rows of teeth of the respective parts of said tapes, there being provided gaps at predetermined intervals in the rows of said teeth for the insertion of sliding clasps; b. attaching an elongated stop member at right angles to the rows of teeth to thereby serve as the lower stop member for the sliding clasp; c. attaching two upper elongated stop members in outwardly splayed fashion with the ends of said upper stop members diverging in the direction of advance of said tapes so that the moving clasp will back over these upper members in sliding towards the lower stop member; and, d. inserting a sliding clasp into one of said gaps of said tape after said lower stop member and said upper stop members have been attached.
Claim 2
Independent Claim 173 words
A method for assembling small prefabricated stop members and for drawing sliding clasps onto engaged sliding-clasp fastener tapes, these fastener tapes comprising tape parts held together by rows of teeth, the method comprising the steps of: a. continuously advancing fastener tapes which are interengaged by rows of teeth of the respective parts of said tapes, there being provided gaps at predetermined intervals in the rows of said teeth for the insertion of sliding clasps; b. attaching an elongated stop member at right angles to the rows of teeth to thereby serve as the lower stop member for the sliding clasp; c. attaching two upper elongated stop members in outwardly splayed fashion with the ends of said upper stop members diverging in the direction of advance of said tapes so that the moving clasp will back over these upper members in sliding towards the lower stop member; and, d. inserting a sliding clasp into one of said gaps of said tape after said lower stop member and said upper stop members have been attached.
Claim 3
Dependent Claim 40 words
A method as claimed in claim 1, wherein said lower and upper stop members are each a U-shaped metal staple having protruding ends which push through the tape parts and are reversedly bent on the underside of said tape parts.
Claim 4
Dependent Claim 50 words
A method as claimed in claim 1, wherein lower and upper stop members are each a U-shaped thermoplastic staple having projecting portions which are pushed through the tape parts and are deformed under the application of heat and pressure to form anchoring elements on the underside of said tape parts.
Claim 5
Dependent Claim 38 words
A method as claimed in claim 1, wherein lower and upper stop members are each a synthetic plastic bar having a flat underside which is welded under heat and pressure to the fabric of the supporting tape parts.
