  • Publication number: 20020124546
    Abstract: A sawtooth wire (20) to be laid in a groove of a shredding element-carrier (10) of a disintegrating roll (1) of an open-end spinning apparatus, is brought into a shape, which essentially represents that shape, which the sawtooth wire (20) is to assume on the said shredding-element carrier (10). The sawtooth wire (20) is preshaped on a dummy body, the circumference of which predominately conforms to that of the shredding-element carrier (10), or the sawtooth wire is directly preshaped on the said shredding-element carrier (10) of the disintegrating roll (1). Only subsequently, is the preshaped sawtooth wire (20) hardened, preferably inductively with the aid of a high frequency alternating current with a frequency of more than 1000 kHz. In this manner, a disintegrating roll (1) is made, the abrasion resistant sawtooth wire (20) of which, after the preshaping, i.e., after its securement on the shredding-element carrier (10), is a hardened, especially inductively hardened steel wire.

  • Patent number: 6337525
    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.

  • Patent number: 6220761
    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.

  • Patent number: 6094901
    Abstract: The present invention concerns a process and an apparatus, in particular a rotor cover (3) and a thread withdrawal tube (2), of an open-end spinning machine, for the pneumatic cleaning of the thread withdrawal tube (2) which has an irregular inner contour. In this arrangement, there opens into the zone of the irregular contour (24, 220) of the thread withdrawal tube (2) an air feed tube (6, 60) directed against the irregular interior contour (24, 200) into the inner space (25) of the thread withdrawal rube (2), through which a flow of air is conducted against the irregular inner contour (24, 220) of the thread withdrawal tube (2). The irregular inner contour (24) of the thread withdrawal tube (2) is formed by means of a disassembly point between two thread guiding elements (20, 21, 22, 23) arranged in sequence, the elements making up the complete thread withdrawal tube (2) or a twist element (220).
