  • 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service position at the elevation of a machine framing of the textile machine can be pivoted away from, or transversely withdrawn from the guide rail.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.
