Abstract

PURPOSE:To manufacture a synthetic resin tube having a receptacle wall with an excellent strength by extruding the synthetic resin tube having a longitudinal channel in the tube wall while increasing its wall thickness at every predetermined interval and further cutting the thickness-increasing wall portion to form the receptacle. CONSTITUTION:A synthetic resin tube having a longitudinal channel C is extruded to be formed while incresaing the thickness of the tube wall at every predetermined interval along the longitudinal direction, the synthetic resin tube is cut down at the termination end or the central portion of the thickness increasing tube wall A and one end of the cut tube is pressed to a receptacle-forming jig including a thickness mold B1 outer mold B2 at a high temperature to form the tap with a wide diameter.
