  • Method of producing a shrinkable product
    Patent number: 5053174
    Abstract: The invention relates to a method for the production of a shrinkable product of a thermoplastic raw material by extrusion. The raw material (1) is extruded through a die (3) to form a pipe (18), whereafter the pipe is cut longitudinally in a cutter (7), spread out, and wound on to a reel (19, 17). The production rate is low and rapid cooling is carried out in a calibration gauge (4). When reheated, a bandlike product (9) thereby shrinks vigorously and is welded to the object in question.
