Reserve-surface cleaner and vacuum for ring-spinning machine

In combination with a ring-spinning machine having

• a longitudinally extending row of spindles each adapted to hold a roving sleeve and each formed below the respective sleeve with a respective reserve winding area and
• a longitudinally extending frame extending along a back side of the row and a service area extending along a front side of the row,
• a reserve-surface cleaning system comprising:
• a guide rail extending on the frame longitudinally along the back side of the row of spindles;
• a cleaner carriage displaceable longitudinally along the rail past the spindles;
• drive means for displacing the cleaner carriage longitudinally along the rail past the spindles;
• means including a set of tools on the cleaner carriage for stripping roving from the reserve surfaces as the cleaner carriage passes same;
• a vacuum carriage displaceable longitudinally along the frame;
• means including a vacuum attachment fixed to the carriage and having an end projecting from the front side back toward the stations level with the reserve surfaces for aspirating roving stripped therefrom by the tools;
• drive means engaged between the vacuum carriage and the frame for displacing the vacuum carriage longitudinally along the frame and thereby sequentially positioning the attachment immediately adjacent the surfaces;
• and
• synchronizing means connected between both of the drive means for synchronously jointly moving the carriages and maintaining the attachment transversely aligned with the tools.
