摘要： Apparatus for use in combination with plastic tube extrusion machinery of the type which heat extrudes continuous tubing for axial passage through a coolant filled elongated chamber, the apparatus consisting of one or more resilient, arcuate bearing members disposed along the elongated chamber in contact with the extruded tubing during the cooling phase and until required rigidity is achieved. The bearing members consist of one or more resilient pads adjustably clamped along a channel member which is rigidly secured axially along the elongated chamber and which includes a coolant water source led directly along the under side of the channel member and extending over each of the resilient pads.
