Abstract (en)
[origin: EP0449073A1] A drafting unit of a spinning frame, having at least one apron drawing zone (3) and a compacting element (9) in the immediate vicinity of the pair of entry rollers (1, 2), is presented. The angle of the contact surfaces of the compacting element (9) with the apron (4, 5) is selected so that the frictional forces exert no appreciable influence on the pressure forces of the entry rollers (1, 2). The compacting element (9) can consequently rest freely on an apron (5) or be mounted resiliently and/or rotatably. <IMAGE>
