ABSTRACT:
An apparatus for making a rotationally symmetrical body formed of crisscross-wound layers includes a winding mandrel, a carriage reciprocating along the mandrel and a thread laying assembly mounted on the carriage. The assembly has a pivotal device, and four thread laying rollers mounted for rotation on the pivotal device. The shafts of the rollers extend parallel to one another and are situated at points of an imaginary equilateral trapezoid having a plane perpendicular to the roller shafts. Each roller has a plurality of circumferential grooves for simultaneously guiding and depositing on the mandrel a plurality of parallel-running threads. Two rollers are situated on one side of the pivot axis of the pivotal device and form a first roller pair and two rollers are situated on an opposite side of the pivot axis and form a second roller pair. Within each roller pair the grooves of the rollers are in alignment with one another, while the grooves of the first roller pair are offset with respect to the grooves of the second roller pair by one half of the center-to-center distance between adjoining grooves. Further, supplying rollers for guiding threads to the first and second roller pairs are provided.
