ABSTRACT:
A process and apparatus for sterile docking of plastic tubes or the like is disclosed in which the tube ends to be joined are sealed by a transverse weld seam and aligned along a common axis. A heating unit is moved between the tube ends at a distance thereto to melt the latter. After retracting the heating unit, the tube ends are urged together. Prior to and during the heating, the tube ends are squeezed behind the weld seam. Immediately after contacting together the tube ends, the squeezing action is discontinued to provide a sterile docking and an opening of the sealed ends.
