ABSTRACT:
A spinning system has a spinning apparatus having a longitudinal succession of spinning stations, a creel extending longitudinally above the apparatus and having respective pendant hangers above the stations and each capable of holding a respective yarn package, and a respective slide above each station supporting the respective hanger slidable between an inner position directly above the respective station and an outer position above but horizontally offset therefrom. A reloading apparatus is displaceable longitudinally along the apparatus at least generally under the hangers in the outer positions of the respective slides. A magazine holds a supply of fresh roving packages on the reloading apparatus and a device is provided on the reloading apparatus for displacing the slide between the inner and outer positions. A grab on the reloading apparatus can grab the package on the hanger in the outer position of the respective slide. The displacing device includes a roller rotatable about a longitudinal axis, a drive for rotating the roller about the axis and an actuator for engaging the roller with the slide while rotating the roller about the axis to displace the slide between the positions.
