Abstract
Traversing rods for a yarn traversing device on textile machines producing cross-wound packages extend over a plurality of winding stations and are subjected alternately to tension and compression. The traversing rod is driven at one end by a traversing drive, and at a distance therefrom, for example at its other end, is driven by an auxiliary traversing device for accelerating its return of motion. This auxiliary traversing device is effective in both directions of motion of the traversing rod, and operates synchronous with a signal given by the traverse drive such that the length changes of long traversing rods are taken into account.
Claims27
A yarn traversing device for a textile machine which in use produces a plurality of cross-wound yarn packages at respective winding stations, comprising:
- a traversing rod extending in use in a machine longitudinal direction adjacent a plurality of respective winding stations, said traversing rod carrying respective yarn guides for guiding yarn to form respective yarn packages at the respective winding stations,
- a traversing drive device drivingly moving the traversing rod in respective back-and-forth longitudinal directions with consequent alternating tension and compression forces on the traversing rod,
- at least one auxiliary traversing drive device spaced longitudinally from the traversing drive device and operable to apply auxiliary driving forces to the traversing rod when said traversing rod movement direction is reversed by said traversing drive device,
- and an auxiliary traversing device control system including a signal generator for generating a traversing drive position signal representative of the position of the traversing drive device and operable to activate the auxiliary traversing device in respective back-and-forth longitudinal directions synchronously as a function of said traversing drive position signal.
