Abstract:
A fiber aggregate is opened into individual fibers, the separated fibers are introduced into a duct having a width smaller than the length of individual fibers, and the fibers are forcefully parallelized in one fixed direction within the duct to produce a fiber assembly of the form such as of web or sliver which has the component fibers arranged parallelly in one same direction.
Abstract:
A twisted yarn is spun by pressing a strand of fibers against a rapidly rotating roller to separate the fibers, pressing the separated fibers against the wall of a main rotary drum, allowing the fibers pressed against the drum wall to be moved in the direction of a fiber condensing portion of the drum, and causing the fibers at this drum portion to be twisted and intertwined with the end of a preceding yarn portion spun in this manner.
