Abstract

Crash or shock absorbing structural components made of fiber reinforced shetic materials and having portions of different diameters including at least one portion of a larger diameter than another portion, are produced by winding synthetic fibers onto a winding arbor (6) in a desired winding pattern. For this purpose a winding support cage (14) is arranged on the winding arbor (6). The winding support cage (14) has circumferential end edges provided with cut-outs (18, 18') for receiving fiber strands. Arresting pins (25, 26) reach into pairs of these cut-outs for temporarily holding the winding support cage (14) against rotation with the winding arbor when a fiber guide (12) moves into a respective starting position for the next winding operation. The cut-outs are so spaced circumferentially and the coordination of the cut-outs to the position of the fiber guide (12) is such that during a winding operation a fiber strand is always deposited in the correct cut-out (18, 18') for producing the desired winding pattern.
