| description | This invention is generally accomplished by providing continuous self-adhesive strands of elastic to a substrate having retractable supports extending therefrom, The retractable supports in a convex pattern are contracted with the self-adhering elastic and the substrate bearing the elastic and supports is brought into contact with the web to which the elastic is to be transferred. The series of supports around which the elastic contacts are forced to retract as the self-adhering elastic is pressed against the web causing the elastic to transfer to the substrate thereby creating an elastic band on the substrate. In a preferred form the substrate is fed two strips of selfadhering elastic that are applied on each side of a series of a convex pattern of pins and then pressed together around opposing sides of the convex pattern of pins to seal the elastic to itself and sever the elastic, creating a contoured closed loop around the pins. |
