摘要： In preparation for the start of spinning with an open-end spinning apparatus, suction is provided outside a fiber transport path on the periphery of an opening roller. Such suction is greater than spinning suction which exists at the mouth of a feed channel leading to the fiber-collecting surface. The fiber stream is thereby guided beyond such mouth to be sucked off. At commencement of actual spinning, this added suction is inactivated, to permit the fiber stream to be initially supplied to the fiber-collecting surface. The fiber stream may be controlled with a suction source connected to a sucking-off orifice via a switching device and a suction line. Less conspicuous and more even thread joins are thereby obtained. Control of suction changes may be effected automatically from a servicing trolley, or in other manners. The invention may be practiced with a variety of types of spinning machines, including but not limited to open-end spinning machines having open end spinning rotors for thread formation or a plurality of friction rollers therefor.

摘要： A pair of draw-off rollers (10, 11) of a thread drawing-off device comprising an over-mounted pressure roller (11) which cooperates resiliently with a driven roller (10) which projects across the front of the pressure roller (11). The pressure roller (11) has at least one recess (113, 114) on its front face (110) which is dimensioned in such a way that it temporarily completely releases a thread (4) sliding along the surface of the driven roller (10) and lying adjacent to the front (110) of the pressure roller (11). By means of a device of this type, the thread (4) is drawn off, for the purposes of joining, to such an extent from the spool (31) that the thread (4) reaches the side (310) of the spool (31) which is facing away from the front (110) of the pressure roller (11) provided with recesses (113, 114). The thread is then introduced into the spinning chamber (2) and is joined. The thread is then guided, using the thread tension, past the front (110) of the pressure roller (11) provided with recesses (113, 114) and introduced into the clamping line of the pair of draw-off rollers (10, 11) and is immediately subjected at this point to a predetermined draw-off.
