ABSTRACT:
A maintenance device is provided in a two-for-one twister textile yarn processing machine having a plurality of spindle assembly stations in side-by-side relationship along the length of the machine for processing of yarn at each station as the yarn is fed from yarn supply packages carried by an adapter device and mounted in the spindle assembly, and an overhead conveyor mechanism extending the length of the machine generally above the spindle assembly stations and including spaced-apart downwardly-directed suspension holders for releasably receiving and carrying adapter devices with full yarn supply packages thereon and adapter devices with substantially empty yarn supply packages thereon to and from respective spindle assembly stations. The maintenance device is constructed for traveling to a respective spindle assembly station, removing an adapter device with substantially empty yarn supply packages from the respective spindle assembly and positioning such adapter device on the conveyor mechanism, and synchronously removing an adapter device with full yarn supply packages from the conveyor mechanism and positioning such adapter device in the respective spindle assembly.
