Abstract: A plurality of separate fiber slivers are introduced into spaced portions of a fiber-separating zone disposed in a combing cylinder-type fiber separating apparatus. The separated fibers are separately discharged into a common duct via a fiber-stripping zone associated with each combing cylinder. The regions of introduction of the separate slivers to the combing cylinder are suitably spaced so that the resulting separated fibers discharged into the duct form a common flow in the portion of the duct between the fiber-stripping zone and the downstream end of the duct. A yarn-spinning apparatus is disposed at the downstream end of the duct for receiving the common flow of the fibers, and such apparatus is mounted for rotation about an axis which is skewed with respect to the axis of the combing cylinder.

Abstract: Open-end spinning unit with a spinning rotor having a lower side and an upper side. A lid is inserted into a front opening provided in said lower side, said lid being bored so as to form a fiber supply duct to convey separated fibers into the interior of said spinning rotor. A yarn take-off duct extends through said upper side of the spinning rotor and conveys the yarn via an outlet port out of the interior of the spinning rotor. A separator is secured to said lid and is designed to divide the rotor interior into a fiber supply zone and a yarn producing and take-off zone.
