Abstract

Windings of fiber compound materials are produced on a core in multicourses hereby the fiber arrangement may change from course to course. For this purpose a plurality of fiber coil carriers are arranged in sequence one after the other as viewed in the direction of core advancement. The fiber coil carriers are arranged coaxially relative to the core. The coils of fibers are supported by the fiber coil carriers. The r.p.m. of each fiber coil carrier is adjustable independently of the r.p.m. of any other coil carrier. Each r.p.m. is adjusted to be inversely proportional to the desired pitch of the fibers in the respective winding course. The direction of rotation of each coil carrier is also selectable independently of the rotational direction of any other coil carrier.
