Abstract
Abstract Continuous self-adhesive strands of elastic (12, 14) are provided to a substrate (22) having retractable supports (24) extending therefrom. The retractable supports (24) in a convex pattern are contacted with the self-adhering elastic (12, 14) and the substrate (22) bearing the elastic (12, 14) and supports (24) is brought into contact with the web (32) to which the elastic (12, 14) is to be transferred. The series of supports (24) around which the elastic (12, 14) contacts are forced to retract as the self-adhering elastic (12, 14) is pressed against the web (32) causing the elastic (12, 14) to transfer to the substrate (22) thereby creating an elastic band on the substrate (22).

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
62 words
A method of applying elastic to a substrate comprising providing at least one strand of elastic, shaping said strand against a holding means, retaining said strand in contact with said holding means, bringing said strand into contact with a substrate, providing means for relative movement of said holding means and said substrate to allow adhering contact of said elastic to said substrate.
Claim 2
Independent Claim
62 words
A method of applying elastic to a substrate comprising providing at least one strand of elastic, shaping said strand against a holding means, retaining said strand in contact with said holding means, bringing said strand into contact with a substrate, providing means for relative movement of said holding means and said substrate to allow adhering contact of said elastic to said substrate.
Claim 3
Dependent Claim
13 words
The method of claim 1, wherein said holding means comprises an inflatable bladder.
Claim 4
Dependent Claim
40 words
The method of claim 1, wherein said holding means comprises a series of pins and the relative movement of said holding means and said substrate is accomplished by the withdrawal of said pins into the base from which they extend.
Claim 5
Independent Claim
16 words
The method of one of claims 1 to 3, wherein said strand of elastic is self-adhering.
Claim 6
Independent Claim
17 words
The method of one of claims 1 to 4, wherein said elastic is shaped into a loop.
Claim 7
Dependent Claim
65 words
Apparatus (230) for applying elastic (242, 244) to a substrate (246) comprising providing at least one strand of elastic (242, 244) providing a holding means (236) for said elastic, providing means to retain said elastic strand in extended condition against said holding means (236), means for bringing said extended strand (242, 244) into adhering contact with a substrate (248) carried by a support means (234).
Claim 8
Dependent Claim
65 words
Apparatus (230) for applying elastic (242, 244) to a substrate (246) comprising providing at least one strand of elastic (242, 244) providing a holding means (236) for said elastic, providing means to retain said elastic strand in extended condition against said holding means (236), means for bringing said extended strand (242, 244) into adhering contact with a substrate (248) carried by a support means (234).
