Abstract
For joining pieces of rubberized tire cords or like sheet material end to end, a pair of coplanar tables are provided which have edges disposed opposite to each other in exact parallelism. Each table is equipped with a retractable stop for positioning a piece of sheet material thereon with its end projecting a predetermined distance beyond the said table edge, and a clamp for temporarily securing the sheet material in position on the table. As one of the tables is then moved toward the other, the pieces of sheet material have their opposed ends preliminarily joined together. The apparatus further comprises at least one finishing roller supported above the tables for rolling the preliminarily formed joint of the sheet material, which roller is in the form of a coil of wire effective both to smooth and to strengthen the joint.
