Abstract: In an individual-spindle-drive type multiple twister that directly employs separate motors to drive the spindle shafts of each twisting unit, when a spindle is inserted into the housing during motor assembly, a rotor and a stator may attract each other and adhere to each other, and this attraction may prevent the spindle shaft from being correctly inserted into a target bearing, thus making it difficult to assemble the motor. A spindle shaft 4 is rotatably supported by bearings 27a and 28a mounted onto upper and lower supporting members 27 and 28. The distance A between the lower end of the rotor magnet 32 of the drive motor 10 fixed to the spindle shaft 4 and the lower end of the spindle shaft 4 is longer than the distance B between the upper end of the stator coil 31, which is fixed to the housing 34 of the drive motor 10, and the bearing 28a of the lower supporting member 28. In addition, the tip 4 of the spindle shaft 4c is tapered to facilitate insertion.

Abstract: A rotary spinning ring structure for use on a spinning frame or the like comprises, as principal components, a stationary tube fixedly supported on a ring rail, a slide ring, a rotating tube assembly supported for rotation by the slide ring on the stationary tube, and a balancing mechanism incorporated into the rotating tube assembly. The rotating tube assembly comprises a rotating tubular body made of an antistatic synthetic resin material, a circular brake ring made of an antistatic synthetic resin material and joined to the rotating tubular body, and a dust cover made of an antistatic synthetic resin material and put on a middle portion of the rotating tubular body. Each of the antistatic synthetic resin materials forming the rotating tubular body, the brake ring and the dust cover is a mixture of a synthetic resin, and fibers, powder or flakes of a conductive material, such as carbon and has a low volume resistivity.

Abstract: The invention provides spinning rings for textile spinning processes having an improved bearing surface formed of a coating of hard nodular chromium which is applied by an electrodeposition process. The spinning rings of the invention can increase the life of travelers that ride on the spinning ring and can provide for high productivity spinning processes.

Abstract: A spindle for spinning or twisting machines comprises a rigid inner sleeve which contains a neck bearing and a step bearing for a rotatably supported shaft and which inner sleeve is accommodated in a bearing housing, the bearing housing being fixed to a spindle rail. The inner sleeve is supported against the bearing housing by two radially symmetrical acting metal springs. The spring rate of the metal spring which faces the neck bearing amounts to at least five times and at most twenty times the spring rate of the metal spring facing the step bearing. The ring space between the inner sleeve and the bearing housing is filled with a highly viscous fluid. The inner sleeve is closed off against the ring space with an oilproof seal.

Abstract: A pot-spinning machine is equipped with a rewinding tube mounted on each yarn guide and with a central, common shogging drive of the yarn guides at one side of the machine. After a yarn break or similar interruption in spinning, in order to be able to initiate the rewinding operation immediately at the affected spinning station while simultaneously continuing the spinning process unchanged at the neighboring spinning stations, the shogging motion of the yarn guide is separated from the motion of the rewinding tube supported on the yarn guide, so that the rewinding tube is then moved only at the forward indexing speed of the yarn guide which is relatively slow compared with the shogging speed and which does not affect the rewinding of yarn onto the rewinding tube.

Abstract: A spinning machine has a third guide eye rail, a third balloon-confining ring rail and a traveller ring rail each of which may be operated by a flexible member from a windless drum and the latter can have an electric motor drive. According to the invention, instead of storing all of the points defining the time course of the movement of the rail, a selected number of points such as starting points for the mean path and amplitude, one or more envelopes, and the amplitude or double amplitude of the oscillation superimposed upon the mean path are determined and a corresponding time course is generated. From the time course at given times determined by the oscillation, the maxima and minima of the path is produced by the evaluation and control unit and used to reverse the motor which raises and lowers the respective rail.

Abstract: A ring-spinning or ring-twisting machine with a ring rail having rings and travelers for each spinning or twisting spindle. The horizontal ring rail is displaceable on rigid vertical rods, the lower ends of which are connected to vertical stretches of flexible traction elements which lie substantially in the vertical plane of the weight axis of the ring rail.

Abstract: A stiff mounting unit is formed by a pair of longitudinal main girders and support bars for a two sided spinning or twisting machine frame. Bridge pieces are connected to these bars and girders. The support rollers and pressing rollers of the drafting or feed units are mounted on the bars.

Abstract: In the case of a machine frame for a ring spinning machine or a ring twisting machine, several vertical columns, which are situated opposite one another in pairs, are provided on each side of the machine distributed in the longitudinal direction of the machine. At the level of the spindle rails, the vertical columns are connected with one another by means of intermediate pieces extending transversely with respect to the longitudinal direction of the machine and, in the area of the upper ends, are connected with one another by means of transverse bridges. The intermediate pieces are used as the supporting elements for the spindle rails of both machine sides. The vertical columns are used as guiding elements for carriages of the ring rails as well as as guiding elements for carriages of yarn guides. With a self-guiding arrangement of the carriages, a lifting movement of the ring rails and of the yarn guides is ensured which is free of jerks and mutually independent.

Abstract: An apparatus for positioning aligned, elongate segments of a ring rail of a textile machine relative to vertically movable ring rail supports includes a centering bore and projection, a lateral guide bore and projection and a longitudinal guide bore and projection. The bores are selectively formed on the vertically movable ring rail supports and the ring rail segments and the projections are correspondingly formed on the other of the ring rail supports and the ring rail segments. The lateral guide bore and projection accommodates variations in the lateral extent of the ring rail segment and the longitudinal guide bore and projection accommodates variations in the longitudinal extent of the ring rail segment so that the ring rail segment is maintained at a predetermined position with respect to the spindles serviced by its associated rings while variations in its longitudinal and lateral extents which may occur due to temperature changes or the like are automatically acccommodated.

Abstract: A suspension assembly (A) for raising and lowering the ring rails (14, 14') of a textile yarn processing machine is disclosed. Vertical guide posts (18, 18') are disposed adjacent to each of the ring rails for guiding the ring rails as they reciprocate vertically. The opposed ring rails are connected by the suspension assembly which includes a parallelogram linkage comprised of a tension rod (24) pivotally connected to opposing bearing brackets (B, C) and a compression rod (26) which is pivotally connected to the opposing bearing brackets. Slide bearings (20, 20' and 22, 22') are carried by the bearing brackets (B, C) for bearing against the guide posts (18, 18'). The lengths of the compression rod and the tension rod are adjusted to bring the spaced slide bearings into light contact with an associated guide post so that the ring rails may be lifted by a lifter mechanism in unison without causing loads on the guide posts.

Abstract: The scaffolding intended for supporting the entire structure of a spinning frame or a like machine is made of individual intermediate sections which are united to a header and a tail section and are serially connected to each other in the intermediate portion of the machine. Each section is composed by two spaced apart shell-like sidewalls connected together by tubular longitudinally extending members. The sections are united by bolting them together so that the tubular members form conduits for removing linters and like airborne materials sucked by an exhauster. Sound-absorbing slabs are inserted between every two adjoining section sidewalls to diminish the noise level.

Abstract: A guide track arrangement for displaceably guiding one or more servicing units at an open-end spinning machine which includes a number of individual spinning units disposed side-by-side. The guide track arrangement includes at least one rail for receiving runners of the one or more servicing units with the at least one rail being fashioned as a supporting profile having attached thereto a guiding profile for guiding the runners of the service unit or units. The guide profile is adjustably secured at the supporting profile at least in a direction of an occurring load on the guide track. A measuring unit is provided which includes a measuring index cooperable with a further index at the spinning units of the spinning machine so as to facilitate adjusting of the guide profile at the supporting profile.

Abstract: An open end spinning machine has individual spinning locations which include a spinning rotor, various drive rollers and conduits and drive shafts which are brought into tangential engagement with drive belts or the like. For this purpose, each spinning location is enclosed in a movable housing which can be displaced vertically on a column mounted on the machine by one end. A stop pin in the column cooperates with a rotating ring in the housing and provides therewith a bayonet-like engagement. The motion of the housing in the opposite direction is limited by the angled arm of a lost-motion slide connected to the housing which makes contact with the stop pin in the column. Easy removal without tools permits ready access to the machine space behind each housing.

Abstract: In a textile yarn twister, means for mounting idler pulleys and the drive tape tensioner spring transversely across the width of the twister between its opposing spindle rails resiliently. The pulleys are rigidly supported by and are interconnected with a transverse beam positioned between a pair of opposing spindle assemblies, the beam being vertically interconnected with each of the spindle rails by a resilient, vibration damping, isolation mount. Shock absorber elements are horizontally interposed between the transverse beam and the spindle rails to prevent shearing of the isolation mounts upon start-up or stoppage of the twister. Adjacent transverse beams are rigidly interconnected by elongate rigid members spaced away from the spindle rails to provide, in all, transverse and longitudinal stability of a plurality of the present mounting means relative the spindle assemblies associated therewith.
