ABSTRACT:
A pair of hollow plastic tubes are welded together by mounting each tube in the clamp jaws of a holder in a bent condition to form the U-shape. A structural element is utilized to create a space between the bight of the U-shape and the holder. The bent tubes are disposed toward each other. A tube section separating member is moved into contact with the bent tubes and through the space between each bight and its holder to create a set of two tube sections from each bent tube. A tube section from one set is aligned with a tube section from the other set and the aligned sections are welded together. The structural element may be a weld seam resulting from a prior welding.
