STERILE DOCKING PROCESS AND APPARATUS FOR PLASTIC TUBE PORTIONS OR THE LIKE

摘要

Lengths of plastic tubing etc., which have been sealed off with a nip weld at the ends, are jointed for continuous winding up. In the process the two ends are brought in line together and fused by a heater inserted between them; the heater is removed and the ends are pressed together. Both before and during the fusing stage the two ends are held at a distance from the heater and with their nip welds parallel to each other; they are pressed together at right angles to their welds but this pressing together is concluded immediately after the ends have been pressed together along their axes.
