An apparatus for making a rotationally symmetrical body formed of crisscross-wound layers, comprises a rotatable winding mandrel, a carriage arranged for travel back and forth along the mandrel; and a thread laying mechanism for receiving simultaneously a plurality of threads from a thread supply and for depositing the threads on the mandrel during rotation thereof and during the back-and-forth travel of the carriage. The thread laying mechanism has a laying roller having a peripheral surface void of grooves. The threads are trained about the peripheral surface of the laying roller and deposited therefrom onto the winding mandrel. The thread laying mechanism further has a guide element for receiving the threads and advancing them to the peripheral surface of the laying roller in predetermined distances from one another.

Apparatus for making crisscross-wound layers to form wound bodies

In the production of fiber reinforced axially symmetrical wound bodies each of predetermined length, by winding fibers or strands of fibers saturated with a hardenable plastic onto a mandrel, alternating layers of circumferential windings and layers with criss-cross windings being placed on top of one another, and, after hardening of the plastic, removing the mandrel, the winding is carried out to simultaneously produce a plurality of identical wound bodies axially juxtaposed on the mandrel by the steps of: winding at least one circumferential layer by attaching a plurality of fibers or strands corresponding to the number of bodies to be wound at axially spaced locations along the mandrel and winding all of the fibers or strands simultaneously on the mandrel with mutual axial spacings approximately corresponding to, or somewhat greater than, the length of each wound body; winding at least one criss-cross winding layer by attaching at least one fiber or strand to the mandrel and winding the fiber or strand over the combined length of the juxtaposed layers of circumferential windings along the mandrel; and dividing the completed wound layers into individual sections forming the respective wound bodies which are then removed from the mandrel.
