Abstract The invention relates to a method for the production of a shrinkable product of a thermoplastic raw ma- terial 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). A similar tech- nique has been used previously as well, but the prob- lem has been that without additives the product so ob- tained is not suitable for purposes such as the insu- lation, joining and covering of pipes. In the present invention, it is essential that the production rate is low and that rapid cooling is carried out in a cali- bration means (4). When reheated, a bandlike product (9) thereby shrinks vigorously and is welded to the object in question. (Figure 1)
