An apparatus is provided for creating an improved configuration of overlapping lengths of flexible thermoplastic strap to accommodate the formation of an improved joint between the strap portions. The apparatus includes first and second strap engaging members respectively defining first and second contoured surfaces for engaging respectively first and second strap lengths to position the joint portions between the strap engaging members in an overlapping relationship along an interface region and to position the trailing portion of each strap length to extend in a plane generally parallel to a reference plane with at least a part of the length of the interface region being non-parallel to the reference plane. In the preferred embodiment, the strap engaging members are each provided with a convex surface and a concave surface and are disposed to align the concave surface of one member generally in registry with the convex surface of the other member.

An apparatus for providing an improved configuration of first and second lengths of flexible thermoplastic strap to accommodate the formation of an improved joint therebetween, said apparatus comprising: first and second opposed strap engaging members adapted to receive between them said strap lengths arranged in an overlapping relationship and to press said lengths together; each said member defining a contoured surface for engaging one of said strap lengths; each said contoured surface including a generally convex surface and a generally concave surface; said strap engaging members being disposed to align said concave surface of said first member generally in registry with said convex surface of said second member and to align said convex surface of said first member generally in registry with said concave surface of said second member. Apparatus for providing an improved configuration of first and second lengths of flexible thermoplastic strap to accommodate the formation of an improved joint therebetween wherein said lengths each have a joint portion and an associated trailing portion extending from said joint portion in a direction away from the other strap length trailing portion, said apparatus comprising: first and second strap engaging members respectively defining first and second contoured surface means for engaging respectively said first and second strap lengths to position said joint portions between said members in an overlapping relationship along an interface region and to position at least part of the length of said trailing portion of each said strap length to extend in a plane generally parallel to a reference plane with at least a part of the length of said interface region being non-parallel to said reference plane.
