ABSTRACT:
For use with a ring spinning apparatus, a drawing frame is described, which comprises two delivery rollers, which define between them an exit nip for a drawn fibrous roving and one of which defines on its air-permeable peripheral surface a deflecting path for the fibrous roving being delivered and a suction zone, which extends along the deflecting path between the exit nip and a pressure, applying roller, which is peripherally spaced from said nip, and the suction zone comprises two juxtaposed and laterally spaced apart branch suction zones, and a blast nozzle is disposed between said branch suction zones and is operable to direct an air blast against the suction-free area which is disposed between the branch zones, whereby the drawn fibrous roving is divided into two branch rovings. The two branch suction zones merge in the suction zone upstream of the pressure-applying roller into a peripherally extending common suction zone portion.
