Abstract: For the formation of a thread withdrawal nozzle for an open-end spinning apparatus which possesses a spin rotor, a thread contact surface (32) of the nozzle is provided with projections (36), which projections close at an obtuse angle (&agr;) with the thread contact surface (32). Thereby, a satisfactory twist propagation is obtained to the fiber entwinement point, so that, in this manner, a softer thread can be produced. Advantageously, the thread is not roughened by this treatment.

The thread cutting device is coordinated with a cleaning apparatus, with the help of which the thread cutting device at specified intervals, and/or in dependency of the carrying out of assigned work phases is subjected to cleaning.

Abstract: The object of the invention is to facilitate the entry of a fiber band into a drawing machine. The invention is comprised of a fiber band insertion apparatus having a combination condenser and guide device with a longitudinal slot extending over its entire length. The guide device is followed by roll pair, which, at least during the laying in of the fiber band, has an accessible entry opening. This opening is at least partially formed by a recess in at least one of the opposed sides of the roll pair. The recess is separated by a flange on one of the circumferential rim surfaces which are mutually profiled to provide space for a compression line for the fiber band. The entry opening of the roll pair and/or feeders, as well as the entry slot of the condenser are, essentially, arranged in a common plane. With the aid of the invented apparatus, the fiber band is laid into the band entry device by a movement transverse to the normal transport direction of the fiber band when the drawing machine is running.

Abstract: The present invention relates to a bearing for an open-end spinning rotor. The latter is driven at its rotor shaft by means of a tangential belt in a predetermined direction and is supported in a nip which is formed by at least two bearing disks capable of being driven by the rotor shaft. A bearing disk (at least one) leads in relation to the drive direction of the tangential belt rotating into the nip, and another bearing disk (at least one) trails in relation to the drive direction of the tangential belt rotating out of the nip. The axis of the bearing disk (at least one) rotating into the nip is at a specified distance from the plane which goes through the rotor shafts of the spinning rotors of several adjoining open-end spinning devices. This distance is being smaller than the distance between the axis of the bearing disk (at least one) rotating out of the nip and the rotor shaft plane.

Abstract: A given plurality of empty round (cylindrical) cans are brought by a can carrier into an empty can magazine of a textile machine which produces a band output. These cans are taken from the can carrier, one after another, to be filled at a filling station from whence filled cans are sequentially moved to a just emptied can carrier in a full can magazine. This can carrier, after the receipt of a given plurality of filled cans, are transported out of the full can magazine. Subsequently, the can carrier, which, in the intervening time, has been emptied and is now to be found in the empty can magazine, is transported by means of an elevated crossover into the full can magazine, which has become free. For the well-timed release of a can carrier loaded with empty cans as well as the transporting of a can carrier from the filling operation loaded with filled cans, there is a Hold Station serving as a buffer zone for an empty can with its can carrier.

According to the invention, the device is provided with a measuring device to detect physical magnitudes connected with the control of the piecing process.

Abstract: In a process for feeding of textile fibers supplied from a point of delivery of a textile machine to a drafting equipment which continues to process the fibers, the fibers supplied from the point of delivery are formed into a fiber sliver. They are then conveyed in the form of the fiber sliver to a drafting equipment which continues to process the fiber sliver, whereby the fibers are conveyed at least in the area before the drafting equipment by a feed mechanism and are introduced by same into the drafting equipment. In a textile machine to carry out the process, the feed mechanism is provided with a conveying channel which is located between the point of delivery and the input area of the drafting equipment and which conveys the fiber sliver. The conveying channel reaches up to the input area of the drafting equipment. The feed mechanism is provided with a drive arrangement for the conveying of the fiber sliver in the conveying channel.

Abstract: The invention concerns an apparatus for the guidance of a spun thread in a spinning station, wherein, after the thread has been produced, it runs in its travel direction through a withdrawal device, a measuring instrument, and a traversing apparatus. The invention makes possible a smooth and stable thread guidance between the withdrawal device and the traversing apparatus, so that both the run of the thread and the quality of wound filament of the thread can be monitored. Between the measuring instrument and the traverse apparatus, at least one deflection roll is provided.

Abstract: A process and an apparatus for storing of a textile material between operating components of spinning mill machines, wherein a first driving device drives an operating component which delivers the material into a storage facility and a second driving device drives another operating component which removes the material from the storage facility. One of the operating components is a high-dynamically reacting component, and the other operating component is a low-dynamically reacting component. The purpose of the invention is to minimize the size of the storage facility and to simultaneously reduce the amount of stored material. This is accomplished in that the quantity of delivered and removed material at any given time is continually measured and a running difference between the two quantities is determined. Dependent upon either a positive or a negative difference from standard, the RPM of the motor (M1) of the driving device for the low-dynamically reacting component (AO1) is controllably adjusted.

Abstract: On a textile machine, arL empty spool (12) is conveyed along a multiplicity of spool stations (1) situated next to one another. In a predetermined position relative to a grasping apparatus (3) the said empty spool (12) is stopped and is picked up by said grasping apparatus (3), and held by its circumferential surface. After its being lifted by the grasping apparatus (3), the spool (12) is retained in an axial alignment. This retention is discontinued, before the spool (12) is released at the spool station (1) where it is required. For the execution of this procedure, a retaining arrangement (8), composed of stopping devices (4 and 5), is provided for the spool (12) which is held by the grasping apparatus (3). The retaining arrangement (8) idles in a location outside of the transport path which the empty spool (12) will occupy when held.

Abstract: The present invention relates to a process and to a device for the control of draft in a drafting system for textile fiber material, whereby a measuring element (MS) which measures the moving fiber material (FM) before its entry into the drafting system (S) transmits measured values (M1 . . . Mn) to a draft regulating system (VR) and whereby the fiber material (FM) is drafted by means of the operating elements of the drafting system after passage of a delay time which is a function of the deviation of the measured values (M1 . . . Mn) from a target value (SW). It is the object of the invention to substantially eliminate fluctuations of the thickness of the fiber material through compensation in a drafting system with draft regulation. This object is attained in that the measured values (M1 . . . Mn) are transmitted to a correction device (SE) and in that an evolution of the draft (K2) and/or a regulating error value (K3) are derived in the correction device (SE) from the measured values (M1 . . .

Abstract: The present invention concerns a procedure and an apparatus for the simultaneous transportation of one group of cans (31, 310, 311) in a row from a can rack (6, 60, 61)—the cans (3) being capable of being filled with fiber band—to a frame machine (2) and/or to another textile machine (4) or to a can depot (5). The group of cans (31, 310, 311) is brought in common with the can rack (6, 60, 61) for the filling of said cans (3) into a first work station (A1) on the frame machine (2). The can rack (6, 60, 61) remains at that point during the filling of the cans (3) of this can group (31, 310, 311) until, after the filling of all the cans (3) on the can rack, the can rack (6, 60, 61) then, once again with the cans, is transported to the additional textile machine (4) or to the can depot 5.

Abstract: In regard to maintenance services at work station, which is located within the maintenance area of a programmable maintenance device along a plurality of similar work stations, attempts of the same maintenance, which have failed at various work stations have been counted. After reaching a specified number of similar failed maintenance procedures, at various work stations (10, 10a, 10b, 10c) a preset function, for instance an alarm, is released. On the other hand, where successful maintenance procedures have been executed, the numbering of the failed attempts reverts to the zero point.

Abstract: For a bearing arrangement of an open-end spin rotor, which is rotatably set in the “V” between circumferential rims of support disks, one or more of the support disks (14), which bear the open-end spin rotor, has a circumferential cleaning groove (3). The cleaning groove (3) can be a self closing, endless groove, which runs over the contact surface of the support disk (14), wherein it generally does not run parallel to the edges of the support disk (14). Such a meandering groove formulation of the support disk circumference assures that no deposits of impurities can accumulate on the rotor shaft.

Abstract: A stretched fiber band is deposited in a can, located in the filling station of a can exchanger of a draw frame, by means of a turntable. The rotational axis of the turntable exhibits an equal to or less than distance from the rotational axis of the can exchanger than the distance from the center point of the can found in the filling station to the rotational axis of the exchanger. Upon the substitution of the filled can by an empty can held in a ready-state position, the operation of the can exchanger on the rotation of the turntable is designed in such a manner, that the fiber band is deposited into the full can exiting the filling station, until this can leaves the zone of the turntable. The fiber band is then deposited into the empty can which has been brought into the filling station II, as soon as this empty can reaches the zone of the turntable.

Abstract: The instant invention relates to a process and to a device for automatic introduction of a fiber sliver into a textile machine equipped with a feed mechanism. The end of the fiber sliver is brought into a defined receiving position in which it is introduced into the feed mechanism. A predetermined length of the end of the fiber sliver is seized. The sliver is then shortened to a second predetermined length and is then introduced into the feed mechanism.

Abstract: Upon filling cans with fiber band, the movable bottom of the cans, as the filling process proceeds, moves downwardly from an initial upper to a lower final position. As this happens, between two elements, one inside, one outside the circumferential shell of the can, a force field is built up in such a way that the element inside the can supports the can bottom and because of the force field, this bottom is held at the same elevation as the element outside of the can. Further, the desired operating height of the can bottom can be correspondingly held. For the lowering of the can bottom, one of the two elements between which the force field exists, is moved relative to the other in the direction of the lower final positioning of the can bottom and the remaining element follows after, because of said force field, until both elements again stand across from one another at the same height.
