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 self-adhering 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.
A method of applying elastic to a web comprising providing at least one strand of self-adhering elastic material, stretching said at least one strand of elastic, forming said elastic strand into a contoured loop by applying said at least one strand against a convex pattern of retractable supports, bringing said supports bearing the contoured elastic strand into contact with a web, causing said supports to retract, and transferring said self-adhering elastic to said web.
A method of forming elasticized areas comprising applying stretched self-adhering elastic strands to form loops around a pattern of supports, bringing said elastic into contact with a deformable web, retracting said supports as said elastic contacts said web and transferring said self-adhering elastic to said web.
A method of applying elastic to a substrate comprising providing at least one strand of elastic shaping said strand against a holding means in the shape of a loop, 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.
