Downstream of the last roller pair of a drafting frame for a spinning machine, the roving is condensed in a fiber-bundling zone having a belt with perforations to which suction is applied. Another belt converges toward the belt with the perforations and engages the roving at a nip spaced from the nip formed by the last roller pair of the drafting frame so that the wedge-shaped converging of the two belts promotes the compacting or condensing action.

Drafting frame for a spinning machine

A reserve-surface cleaning apparatus is used 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. The cleaning system has 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, and a drive for displacing the cleaner carriage longitudinally along the rail past the spindles. A set of tools on the cleaner carriage strips roving from the reserve surfaces as the cleaner carriage passes same. A vacuum carriage displaceable longitudinally along the frame has an attachment with an end projecting from the front side back toward the stations level with the reserve surfaces for aspirating roving stripped therefrom by the tools and a drive engaged between the vacuum carriage and the frame displaces the vacuum carriage longitudinally along the frame and thereby sequentially positions the attachment immediately adjacent the surfaces. A synchronizing unit connected between both of the drives synchronously jointly moves the carriages and maintains the attachment transversely aligned with the tools.

Reserve-surface cleaner and vacuum for ring-spinning machine

In a ring-spinning or -twisting machine a longitudinal row of upright and normally rotating spindles mounted on a common support beam each have a lower reserve surface below a sleeve normally carried on the spindle. An apparatus for clearing roving wound on the surface has a guide rail extending longitudinally along a back side of the beam adjacent the spindles, a carriage displaceable along the rail past the spindles, and a drive including a longitudinally extending drive element secured to the carriage for displacing same longitudinally along the rail past the spindles. A roving-cutting element is fixed on the carriage engageable immediately adjacent the spindles between the respective lower reserve surfaces and sleeves and a roving-clearing element is fixed on the carriage below the cutting element and engageable immediately adjacent the lower reserve surfaces of the spindles.
