Abstract
A ring-spinning apparatus has a service carriage which can be positioned opposite a stationary waste-collection receptacle so that the mobile waste-collection receptacle of the carriage can be aligned therewith and shifted toward the stationary waste-collection receptable thereby coupling the doors of the receptacle. An actuator can simultaneously open the coupled doors to permit a pressure drop to draw lint and roving scraps collected in the receptacle of the carriage into the receptacle of the machine.
