Abstract

Process for carrying out the control of the dimensions of the thermoplastic tubes, characterized in that the combination of an apparatus for stretching the thermoplastic tube is established, provided with a device for maintaining a predetermined dimension of the outer diameter of said tube according to any change detected in the plastic area of the tube as it is stretched, the control comprising elements for deriving a first signal with a value representative of the mass of the cross section of said tube; as well as a second preset signal with a value representative of the mass of the tube cross section having a predetermined outside diameter and a predetermined inside diameter; a device for receiving the two cited signals and for regulating the value of a third signal proportionally to the variations in the value between said first and second signals; and means responsive to said third signal to control the drawing speed of said tube and to proportionally regulate said speed but only according to the adjustments in the value of said third signal.
