Abstract
Improvements introduced in apparatus for the extrusion and stretching of plastic tubes, characterized in that it comprises, at least, means for preheating a tube of plastic material to near an appropriate temperature to soften it; pivot or mandrel means, of substantially increasing section as a whole in the forward direction of the tube, and means for forcing said tube by stretching it on said central pivot or mandrel means, so that said tube undergoes an elongation of the internal section and a thinning of its thickness; means for cooling the tube that has been stretched in this way.
