  • Method of and apparatus for spinning yarns from staple fibers by an open-end spinning technique
    Patent number: 3998040
    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.
