Abstract

The opposite ends of a web are joined by welding to form a continuous belt. The welded web comprises a first edge (end) having at least one aperture overlapping a second edge (end) of the web, the web comprising thermoplastic material on at least the exposed surface along the second edge, to form a region of contiguous contact between the first edge and the second edge, at least a portion of the thermoplastic material at least partially filling the aperture thereby bonding the first edge to the second edge. The welded web may be prepared by forming at least one aperture in at least the first edge, overlapping the first edge over the thermoplastic material on the exposed surface along a second edge whereby the thermoplastic material on the second edge at least covers the aperture to form a region of contiguous contact between the first edge and the second edge and thereafter raising the temperature at least in the region of contiguous contact adjacent the aperture whereby thermoplastic material from the second edge at least partially fills the aperture thereby bonding the first edge to the second edge.
