Abstract
A power-driven, wheeled vehicle which interacts semiautomatically with winders in a spinning area to doff completed yarn packages, automatically delivers the packages to an unload station to unload the packages from the vehicle and then moves to another winder to repeat the operation. The wheeled vehicle and the winders are located on opposite sides of a service aisle. A frame extendable and retractable across the aisle is mounted to the vehicle. The means for extending and retracting the frame includes two four-bar linkages coupled to the vehicle and the frame and to each other.
