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).
