Abstract
Abstract A method is disclosed for producing zip fasteners having applied thereon tags indicating information relative to zip fastener products. Continuous production of these zip fasteners is made possible by feeding a train of tags in a direction at right angles to the direction of movement of a zip fastener chain.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
120 words
A method for producing tagged zip fasteners which comprises providing a train of tags each having a fold line along which it is foldable, feeding said train of tags in a direction at right angles to the direction of movement of said fastener chain until said tags are borught one at a time successively into a predetermined position on said fastener chain, attaching an end of said tag onto said fastener chain with the fold line of said tag lying adjacent to a cutting line of said fastener chain along which said chain is to be cut to a product length, separating the thus attached tag from its train of tags, and cutting said fastener chain along said cutting line.
Claim 2
Independent Claim
120 words
A method for producing tagged zip fasteners which comprises providing a train of tags each having a fold line along which it is foldable, feeding said train of tags in a direction at right angles to the direction of movement of said fastener chain until said tags are borught one at a time successively into a predetermined position on said fastener chain, attaching an end of said tag onto said fastener chain with the fold line of said tag lying adjacent to a cutting line of said fastener chain along which said chain is to be cut to a product length, separating the thus attached tag from its train of tags, and cutting said fastener chain along said cutting line.
Claim 3
Dependent Claim
32 words
The method as defined in claim 1 wherein said train of tags are supplied in folded position so that the fastener chain can be cut simultaneously with the separation of said tags.
Claim 4
Independent Claim
161 words
A method for producing tagged zip fasteners comprising: providing both a series of connected together tags and a continuous length of fastener chain composed of a series of zip fastener sections each having fastener elements having stop members at opposite ends thereof; intermittently feeding said length of fastener chain along a path of travel to successively and intermittently position each zip fastener section in a common working position; intermittently feeding said series of connected together tags transversely to the feeding direction of said length of fastener chain to successively and intermittently superposition individual tags over the end portions of individual zip fastener sections when the latter are in said common working position; attaching the superposed tags to their respective zip fastener sections to form a tagged zip fastener section; and separating both each attached tag from the remaining series of tags and each tagged zip fastener section from the remaining length of fastener chain to form individual tagged zip fastener sections.
Claim 5
Independent Claim
161 words
A method for producing tagged zip fasteners comprising: providing both a series of connected together tags and a continuous length of fastener chain composed of a series of zip fastener sections each having fastener elements having stop members at opposite ends thereof; intermittently feeding said length of fastener chain along a path of travel to successively and intermittently position each zip fastener section in a common working position; intermittently feeding said series of connected together tags transversely to the feeding direction of said length of fastener chain to successively and intermittently superposition individual tags over the end portions of individual zip fastener sections when the latter are in said common working position; attaching the superposed tags to their respective zip fastener sections to form a tagged zip fastener section; and separating both each attached tag from the remaining series of tags and each tagged zip fastener section from the remaining length of fastener chain to form individual tagged zip fastener sections.
Claim 6
Dependent Claim
45 words
A method according to claim 3; wherein said separating step comprises breaking the attached tag from the remaining series of tags by folding the attached tag along a predetermined fold line and cutting the tagged zip fastener section from the remaining length of fastener chain.
