Abstract: Method of controlling a thread-joining operation in a rotor-spinning machine having a rotor formed with a fiber-collecting channel, wherein a pulse proportional to the rotary speed of the rotor is applied to control a measure of the material being processed in the spinning operation which includes automatically controlling advance feeding into the rotor of a quantity of fiber required for thread-joining and feeding the fiber beginning with withdrawal of a thread formed for the fiber as well as returning into the rotor the thread end to be joined and withdrawing the joined thread from the rotor during start-up of the rotor, the automatic control being in accordance with a quantity proportional to the peripheral velocity of the fiber-collecting channel of the rotor serving as control input variable for at least one of the fiber feed, the thread withdrawal, the beginning of the advance feeding and the beginning of the returning of the thread end, and device for carrying out the method.

Abstract: Device for controlling the contact pressure of a textile coil on a support or drive cylinder includes articulatingly suspended coil holder means for rotatably supporting the coil over the cylinder, a spring-loaded toggle-joint assembly being movable in a given plane into positions thereof wherein it is partly and fully extended, the toggle-joint assembly including a lever articulatingly connected to the coil holder means, and means for adjusting in the given plane the direction in which the toggle-joint assembly extends in the fully extended position thereof.

Abstract: Feeding apparatus is provided for an open-end spinning assembly which includes a feeding table and feed roller facing one another to form a nip which offers sliver to an opening roll disposed downstream thereof. Upstream of the feed roll and feeding table ther is provided a sliver funnel which has an outlet opening facing the feed table and feed roller. In order to accommodate correct laying of the sliver in the sliver funnel so that it is properly disposed with respect to the feeding apparatus, the sliver funnel is disposed and configured so that the outlet opening thereof is visually exposable without opening the housing for the feed roll and feed table. According to preferred embodiments, the sliver funnel is mounted for movement between an in-use position and a servicing position, with the outlet opening being visible when in the servicing position so as to accommodate laying in of the sliver.

Abstract: In a rotor spinning machine having a multiplicity of spinning stations and sliver containers disposed in tandem in two rows, a device for replacing the sliver containers includes a rotary table having means for carrying four sliver containers for a respective group of four spinning stations.

Abstract: Method of irregularizing or disturbing the winding pattern in apparatus for winding cross-wound coils with a constant thread feeding velocity having a reciprocating thread guide which is driven for time intervals alternatingly with at least two different speeds, which includes driving a cross-wound coil in synchronism with and dependent upon the motion of the thread guide so that the quotient of the peripheral speed of the cross-wound coil and the cosine of half the thread crossing angle is constant; and device for carrying out the method.

Abstract: Method of protecting against destruction of or damage to tangential strands and rotatable members of a textile machine having a plurality of individual work stations and operating with traveling threads, which includes monitoring with a monitoring device traveling along the textile machine the rotation of the rotatable members of the textile machine driven by the tangential strands thereof, determining non-rotation of at least one of the rotatable members or decrease of speed of rotation thereof below a given value at a given work station of the textile machine and accordingly disengaging the respective tangential strand at the given work station from frictional engagement and securing it against renewed frictional engagement; and device for carrying out the foregoing method.

Abstract: A method for terminating the spinning operation in a spinning machine having a loosening-up and a feeding device for slivers, includes the steps of running a sliver having a substantially full cross section with a substantially uniform count over the entire length thereof through the sliver feeding device and the fiber loosening-up device, and cleanly cutting the sliver transversely immediately upstream of the feeding device in direction of feed of the sliver; and device for performing the foregoing method.

Abstract: Traveling holder for textile coils includes a receptacle, and an elevator disposed in the interior of the receptacle, the elevator having a loopshaped travel path within the receptacle.

Abstract: Method of winding conical cross-wound coils at constant thread feed velocity wherein compensation is provided by a storage device for the varying winding speeds from the larger to the smaller diameters of the coils which includes setting a thread storage device in zero position thereof, wherein no thread is being stored, after alternative occurrence of a coil change and a thread break; initially holding with an auxiliary thread guide a thread that is to be wound into a coil; advancing a thread guiding member in a direction from the larger toward the smaller diameter ends of the coil and, after releasing the thread from the auxiliary thread guide, taking over the thread with the thread guiding member.

Abstract: Self-centering holder for hollow textile coils of varied lengths and diameters includes at least two rod-shaped substantially parallel-extending centering and clamping members, and means includes support and adjusting members for the centering and clamping members, the at least two centering and clamping members being mounted on the support and adjusting members and being respectively pivotable into a position wherein a hollow textile coil of given diameter is receivable over the centering and clamping members collectively and wherein the latter are in pressing engagement with the inner surface of the hollow textile coil, the support and adjusting members being located outside the hollow textile coil when the latter is received on the centering and clamping members.
