Abstract
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.
