In the case of a spinning or twisting machine, it is provided that the spindles are each driven by separate electric motors which, together with their bearings, are arranged in a spindle rail constructed as a longitudinal duct, the stators and the rotors of the electric motors being disposed in the longitudinal duct in an exposed manner.
摘要:
A textile spinning or twisting machine which has plurality of units arranged next to one another in a row on one or both sides of the machine which each contain an electric motor. These electric motors are mounted on a supporting body extending in the longitudinal direction of the machine. The supporting body is constructed as a cable duct which, for each electric motor, comprises a motor plate bar and electric lines laid in the longitudinal direction of the machine.

A device for interrupting feed of a roving on a drawing frame, having a feed roller pair, e.g., a powered bottom roller and a top roller tensioned against the bottom roller by springs, includes a clamp for lifting the top roller away from the bottom roller and clamping the roving against the circumference of the top roller. The clamp is disposed on a lever pivotable about an axis parallel to the axes of the feed roller pair and is shiftable with respect to a clamping edge, in the feed direction of the roving, toward the circumference of the top roller. The clamp includes a tongue which initially engages in the nip between the rollers and a portion having a toothed profile which cooperates with the clamping edge by engaging the roving.

In order to permit an open-end spinning unit to be opened with a relatively small amount of force, there is a swivel lid which covers all parts, without these parts being attached thereto. However in order to enable the opener roller to be stopped when the open-end spinning unit is opened, the opener roller is located in a swivel housing, which swivels when the lid is opened, thereby interrupting the drive of the opener roller, as a wharve of the opener roller lifts away from a tangential belt.

A spindle-shaped component for an air jet spinning arrangement is described. The component includes a base body and an attached tip, as well as a yarn withdrawal channel which extends through the base body and the tip, the first part of the yarn withdrawal channel being an entry opening in the tip. The spindle-shaped component also has an injection channel which runs into the yarn withdrawal channel, the injection channel being directed in the direction of the entry opening of the yarn withdrawal channel. The injection channel is formed by a surface area of the base body and a surface area of the tip.

The invention concerns a cleaning apparatus for the cleaning of a spin rotor of a spinning station leaning head which can be insertably presented to the spin rotor and on which cleaning head are placed at least two scraper elements. In accord with the invention, the at least two scraper elements are pneumatically extendable, wherein the position of the two scraper elements are so secured on the outer circumference of the cleaning head, that the sum of the contact forces which are exerted from the scraper element in the radial direction onto the rotor is zero, or practically zero.

An arrangement for an open-end rotor spinning comprises a spinning rotor which is radially supported with a rotatable shaft in a wedge-shaped gap of two supporting disc pairs and axially in a step bearing housing. The shaft can be pulled out from its support from the operator's side of the arrangement and inserted again into the support. For the purpose of cleaning the gap between the back supporting disc pair and the front face side of the step bearing housing, a tube is provided having an entry opening at the operator's side of the arrangement and leading to the area of the step bearing housing and aligned against the shaft with an opening.

A ring spindle assembly and process for re-lubricating a ring spindle having a vertically arranged bearing housing with a closed bottom. A step bearing is arranged in an oil-bath of the bearing housing for a rotating shaft. In the bearing housing, at least two lubricating channels are provided above the desired oil level of the oil-bath. When the shaft remains in the bearing housing, oil is filled into one lubricating channel until oil comes out of the other lubricating channel. A certain amount of oil is subsequently sucked out through the lubricating channel, so that the oil reaches the desired level.

An arrangement is provided for sealing the opening of a rotor housing under a low pressure, through which opening a shaft for a spinning rotor extends, which shaft is supported outside of the rotor housing. This arrangement comprises a sealing disk, which is supported floating relative to the opening and which is pressed against a bearing surface by means of a spring element. The floating sealing disk comprises a through bore hole having a narrow tolerance relative to the shaft. The spring element presses against the effect of the low pressure.

Traversing rods for a yarn traversing device on textile machines producing cross-wound packages extend over a plurality of winding stations and are subjected alternately to tension and compression. The traversing rod is driven at one end by a traversing drive, and at a distance therefrom, for example at its other end, is driven by an auxiliary traversing device for accelerating its return of motion. This auxiliary traversing device is effective in both directions of motion of the traversing rod, and operates synchronous with a signal given by the traverse drive such that the length changes of long traversing rods are taken into account.
