ABSTRACT:
A stationary mandrel (1) is wrapped in a separating film (3) at the front, as seen in the draw-off direction (A). A gel coat layer is coated onto the film (3) and partly gelled by means of a heater (12). The gel coat layer is coated with liquid polyester, wrapped in a longitudinally extending glass-fibre fabric (20) in an overlapping manner and wound helically in a glass sliver (21). These layers are hardened by means of a further heater (24,25), so that a structural supporting profile for coating on the following layers is obtained. The mandrel (1) is set off after the further heater (24,25). For coating on the further layers, liquid polyester, a fibre fabric (34) and a helically wound sliver (37) are applied alternately. These layers are fulled and coated with an outer gel coat layer. The polyester is hardened in an oven (50). A grab device (52) draws the section off continuously from the mandrel (1). Finally, the section is cut to length. A hollow section of high strength is produced by means of this process.
