Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
243 words
In combination with an apparatus for applying a patch such as a section of hook and loop-type fastener tape and the like to a substrate said patch having an upper surface and a lower surface coated with an adhesive requiring the application of heat thereto prior to applying said patch to the substrate, said apparatus including a head for gripping the patch along the upper surface thereof, means for moving said head between a first position where said head receives the patch and the undersurface thereof is exposed and a second position where said head applies pressure against the patch to apply same to the substrate, the improvement comprising a heating element, a yoke mounting said heating element, means for pivotally connecting said yoke to said head, means connected to said head moving means for selectively rotating said yoke to selectively interpose said heater element between said head and said substrate and for withdrawing said heating element to a position adjacent to said head, means for selectively arresting movement of said head toward the substrate when the heating element is positioned between said head and said substrate to permit the heating element simultaneously to apply heat to said patch and said substrate, and for selectively withdrawing said arresting means when said patch and said substrate are sufficiently heated so as to permit said headmoving means to move said head toward said substrate to its second position and apply the patch against the substrate.
Claim 2
Dependent Claim
243 words
In combination with an apparatus for applying a patch such as a section of hook and loop-type fastener tape and the like to a substrate said patch having an upper surface and a lower surface coated with an adhesive requiring the application of heat thereto prior to applying said patch to the substrate, said apparatus including a head for gripping the patch along the upper surface thereof, means for moving said head between a first position where said head receives the patch and the undersurface thereof is exposed and a second position where said head applies pressure against the patch to apply same to the substrate, the improvement comprising a heating element, a yoke mounting said heating element, means for pivotally connecting said yoke to said head, means connected to said head moving means for selectively rotating said yoke to selectively interpose said heater element between said head and said substrate and for withdrawing said heating element to a position adjacent to said head, means for selectively arresting movement of said head toward the substrate when the heating element is positioned between said head and said substrate to permit the heating element simultaneously to apply heat to said patch and said substrate, and for selectively withdrawing said arresting means when said patch and said substrate are sufficiently heated so as to permit said headmoving means to move said head toward said substrate to its second position and apply the patch against the substrate.
Claim 3
Dependent Claim
122 words
The apparatus of claim 1 which includes a reciprocable plate, means for moving said plate, a mounting block defining a slot for receiving a stop member slidably movable toward and away from the head moving means, said plate defining a slot angularly disposed with respect to said stop member, a pin attached to said member received within the slot in said plate whereby reciprocable movements of said plate cause sliding movement of said stop member, and means connected to said head moving means for contacting said stop member when said member is extended toward the head moving means, to arrest movement of said head toward the substrate and to permit the heating element simultaneously to apply heat to said patch and substrate.
Claim 4
Dependent Claim
41 words
The apparatus of claim 2 wherein said head includes vacuum pressure means for holding the patch, and said heating element is a flat generally sinusoidal combination of sections arranged closely together to prohibit substantial passage of air therebetween toward said head.
Claim 5
Dependent Claim
37 words
The apparatus of claim 3 wherein electrical circuit means are provided for directing a large amount of current to said heater element for an initial period, followed by a lesser amount of current for a longer period.
