Guiding rail for e.g. sun curtain, has guiding slot exhibiting between two open ends of C-profile, and fibers extending in longitudinal direction, where rail is made of duro-plastic, in which filaments are laid in traction direction

摘要

The rail has a guiding slot (9) exhibiting between two open ends of a C-profile and comprising width of maximum 2 mm, where the rail is made of duro- plastic. Fibers extend in a longitudinal direction, and filaments are laid in the duro- plastic in a traction direction. The duro-plastic is drawn from a molded cavity in a heated tool, where temperature gradient is produced at the tool. The gradient exhibits temperature that is decreased transverse to a level by the slot to counteract closing of the slot of the C-profile, during cooling process. Independent claims are also included for the following: (1) a method for manufacturing the guiding rail (2) a device for implementing the method for manufacturing the guiding rail.
