Abstract

Abstract Structures are provided in attachment means for textile fasteners such as buttons and the like. In one form, a flexible thread or filament is secured between a fastener such as a button and textile material and is reinforced by means of a plastic material. A plurality of loops of the thread are secured together with a plastic which not only reinforces the thread but also serves to prevent its unwinding from the textile material and fastener. The reinforcing plastic may also be bonded or welded to the fastener and the textile material. In another form, the thread or filament is coated with or comprises a heat sealable plastic wherein a specially heated tool is employed to seal same to itself and in certain instances the fastener and the textile material.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 192 words
An apparatus for reinforcing thread-like fastening means for a button fastener comprising in combination: a support for a garment with a button threadably secured to said garment, said support having a garment with a button prepositioned by said garment with respect to said support, a plurality of cooperating dies prepositioned with respect to said support and disposed adjacent the button of said garment supported on said support, each of said dies having respective tip portions, and means for disposing said tip portions between said button and the surface of said garment to which said button is threadably secured, means for moving said dies toward and away from each other to permit said dies to engage the filamentary thread-like material joining said button to said garment therebetween, and means for energizing said dies while they are disposed close to each other to effect the welding together of said filamentary material disposed between said button and said garment in a manner to join said filamentary material to itself and prevent the longitudinal movement of said filamentary material between said button and said garment and to thereby prevent fraying and loosening of said filamentary material.
Claim 2
Independent Claim 192 words
An apparatus for reinforcing thread-like fastening means for a button fastener comprising in combination: a support for a garment with a button threadably secured to said garment, said support having a garment with a button prepositioned by said garment with respect to said support, a plurality of cooperating dies prepositioned with respect to said support and disposed adjacent the button of said garment supported on said support, each of said dies having respective tip portions, and means for disposing said tip portions between said button and the surface of said garment to which said button is threadably secured, means for moving said dies toward and away from each other to permit said dies to engage the filamentary thread-like material joining said button to said garment therebetween, and means for energizing said dies while they are disposed close to each other to effect the welding together of said filamentary material disposed between said button and said garment in a manner to join said filamentary material to itself and prevent the longitudinal movement of said filamentary material between said button and said garment and to thereby prevent fraying and loosening of said filamentary material.
Claim 3
Dependent Claim 37 words
A device in accordance with claim 1 including means supported between said dies for prepositioning a button fastener with the dies movable beneath the button fastener against the thread-like material securing the button fastener to said garment.
Claim 4
Dependent Claim 25 words
A device in accordance with claim 2 including means disposed between said dies for sewing a button fastener disposed between said dies to said garment.
Claim 5
Dependent Claim 22 words
A device in accordance with claim 1 wherein said means for applying sealing energy to said dies comprises a radio frequency generator.
Claim 6
Dependent Claim 23 words
A device in accordance with claim 1 wherein at least one of said dies is pivotally supported for movement toward the other die.
Claim 7
Dependent Claim 26 words
A device in accordance with claim 1 wherein both of said dies are supported for pivotal movement and are moveable toward and away from each other.
Claim 8
Dependent Claim 51 words
A device in accordance with claim 1 including means disposed between said cooperating dies for holding a button fastener in position while said dies are moved beneath said button fastener and operated to engage and weld said filamentary thread-like material between the button and garment to which said button is fastened.
Claim 9
Dependent Claim 32 words
A device in accordance with claim 2 including means for flowing an adhesive material to the thread-like material while said button fastener is held by said means disposed between said cooperating dies.
