  • Publication number: 20170175299
    Abstract: With a method for controlling a setting process for re-setting a yarn (G) at a textile machine, in particular a spinning machine (1), by means of a setting device (5), a multiple number of work steps as preparation for the actual setting operation are carried out successively in a chronological sequence. In each case, a predetermined time period is allocated to the work steps within which the respective work step is carried out. For at least one of the work steps, the predetermined time period can be varied, whereas the current time period of the at least one work step is determined as a function of a yarn characteristic (GC) of the currently produced yarn (G and/or as a function of a utilization of the setting device (5). A textile machine features a control unit (12), which is designed to operate the textile machine according to this method.

  • Publication number: 20170009386
    Abstract: The invention relates to a method for operating a spinning machine with a multiple number of spinning stations, whereas, in the normal case, the individual spinning stations are supplied with a fiber material and produce a yarn from this, whereas, upon the occurrence of predefined events, yarn production is interrupted at any or all spinning stations, whereas the spinning stations at which yarn production has been interrupted are, when required, spun in with the assistance of a spinning-in process in order to once again start up yarn production, and whereas the respective spinning-in is carried out with the assistance of handling tools with their own spinning machines.

    Abstract: The method and corresponding device of yarn braking are provided by means of an attending device provided with a vacuum tube into which the end of the yarn is sucked in before commencement of braking. At drawing off from the vacuum tube, the yarn is braked between the braking surfaces of a stationary brake friction member and a moving brake friction member, which are arranged on the attending device displaceably to the track of the yarn. For generating the braking force, the moving brake friction member moves towards the stationary brake friction member and fits against it at a contact abscissa or a contact surface.

  • Patent number: 7113843
    Abstract: The invention relates to a method for the maintenance of a plurality of processing stations (13) of a textile machine (10), whereby at least one first maintenance unit (14a-d) can travel alongside the processing stations (13) in order to service and/or control the processing stations (13). The maintenance unit (14a-d) may be moved into an optimized readiness position when none of the processing stations (13) needs to be serviced and/or controlled by the maintenance unit. Alternatively, the direction of travel in which the maintenance unit (14a-d) is to travel to the next processing station (13) in need of service is determined, whereby the direction of travel depends on the totality of processing stations in need of maintenance.

  • Publication number: 20050182509
    Abstract: Proposed is a procedure for the control of a service module for the maintenance of spinning stations and also a service module for the carrying out of this said maintenance. The procedure is carried out on a spinning machine, which can run at least one activity (A) at individual spinning stations, whereby this activity (A) consists, respectively, of at least one task (I-IV). In a case of a disturbance (4) in the course of the working of a task (I-IV), then the service module is immediately disconnected from automatic operation and is set in stillstand and subsequently, by the said service module itself, at least one procedure (a, b, c, d) for the correction of the said disturbance is carried out in order to complete the activity (A) which is to be carried out, or the service module is reset, into a fully operable state.

  • Patent number: 6772697
    Abstract: The invention concerns an arrangement of service positions for maintenance apparatus, which can travel on a guide rail along a multiplicity of similar workstations on a first side of a textile machine, wherein a maintenance apparatus in a first service position at the elevation of a machine framing of the textile machine can be pivoted away from, or transversely withdrawn from the guide rail. Per side of the textile machine, at least two maintenance apparatuses are exclusively assigned thereto, whereby the guide rail on the first side, at least at one end of the textile machine, is elongated beyond the textile machine and a second service position is placed on the elongated guide rail. In this way, it becomes possible, with a large number of workstations to assure the shortest possible duration of a standstill, wherein in the case of a failure or preventive unkeep of one maintenance apparatus, another maintenance apparatus can serve a workstation in a short time.

  • Patent number: 6662542
    Abstract: In open-end spinning and in coordination with predetermined operating phases, a yarn suction pipe by means of which a yarn extending from a bobbin is to be received temporarily is brought successively into different operating planes. The yarn suction pipe is imparted a defined operational movement as a function of the operating planes occupied and in coordination with the current operating phase. The operating positions of the yarn suction pipe that can be moved into at least two operating planes are defined in such a manner that when the yarn suction pipe is in its operating position in a first operating plane, a yarn extending from the bobbin pressing on a winding roller to the yarn suction pipe crosses the traversing range of the yarn traversing guide. However, the yarn is outside the traversing range of this yarn traversing guide when the yarn suction pipe assumes its operating position in an additional operating plane.
