摘要： A sliver guide has a restrictor and deflectors for imposing uniform transverse forces on a sliver immediately before the latter is supplied to a feed roller in an open-end spinning unit, thereby spreading the sliver and loosening the core thereof. The sliver guide serves to prevent grain variations and neps that are otherwise caused in the spun yarn by the hard core and twists of the sliver which naturally form as the latter is being produced.

摘要： A yarn draw off tube for an open-end spinning unit which improves the twist transmission to a fiber ribbon in a spinning rotor. The yarn draw off tube is provided with a yarn inlet on the top wall thereof and a yarn outlet on the lower side wall thereof, and the yarn inlet is eccentric from the center in a direction opposite to the yarn outlet. In the spinning operation, a twist imparted to a yarn drawn off from the spinning rotor can smoothly be transmitted to the root portion thereof. Thereby, yarn breakage is restrained and a yarn of good appearance and strength can be obtained.

摘要： An apparatus for removing trash in an open-end spinning frame is disclosed herein. According to the invention, an open-end spinning unit is provided with a trash transporting chamber which is communicated with an opening which is formed on part of the inner peripheral surface of a space in which a combing roller is rotatably disposed and through which part of the circumferential surface of the rotating combing roller is exposed. The trash transporting chamber is so constructed that its interior is placed substantially under an atmospheric pressure, and a side wall thereof facing opposedly toward the opening is spaced from the circumferential surface of the combing roller exposed through said opening at a distance falling within a range from a dimension which is substantially equal to the diameter of the combing roller to a dimension which is about two times said diameter.
