Abstract
A method and apparatus for continuously seaming cured EPDM membrane to form a composite sheet of predetermined width and indefinite length. The method includes the steps of providing at least two rolls of cured EPDM membrane having longitudinal marginal edges and feeding the cured EPDM membrane from the at least two rolls in a first direction. The longitudinal marginal edges of the cured EPDM membranes are positioned in an overlapping relationship as the cured EPDM membranes are fed in the first direction and then the overlapping longitudinal marginal edges are continuously seamed to form a composite sheet of indefinite length.
