Abstract (en)
[origin: EP0336210A2] A spinning method, such as open-end spinning, in which neps contained in the staple fibre material come to rest for the most part inside the yarn, is used. The staple fibre material is nevertheless subjected to a combing before the spinning. But a simplified combing is employed. The staple fibres are fed in the form of a lap (W) to a gripper unit (11, 13) which first administers in each case a tuft to a rotating round comb (18, 19). The gripper unit (11, 13) is thereafter advanced and feeds the combed-out tuft into the nip of breaking cylinders (6) directly without contact with further comb elements. The omission of the otherwise always used fixed comb in front of the breaking cylinders allows a higher weight of the lap (W) and therefore an increased production of the combing device. An improvement of the yarn can thereby be achieved economically. <IMAGE>
