Abstract
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.
