ABSTRACT:
A method of and an apparatus for cooling or quenching a tube extruded from a water soluble polymer includes a plurality of cooling rings with bores through which the extruded tube passes. A gaseous cooling medium, such as compressed air, is supplied to each cooling ring and is directed immediately downstream of the bore thereof to impinge upon and cool the tubing passing therethrough. The cooling medium is supplied annularly so as to maintain the just-extruded tubing concentric and keep it centered in the bore.
