Abstract: In order to float a yarn better into the nip of the pair of input rollers (2, 3) of a drawing unit on a fine-spinning machine, in particular a jet-spinning machine, the invention calls for a cone-like end-piece (5) to be fitted to the pressure-roller (3) of the pair of delivery rollers (2, 3). The end-piece (5) is preferably connected rigidly to the spindle of the pressure-roller. This prevents the yarn from being damaged during the preparatory phase, before the yarn is floated into the rollers, which ensures that the yarn is introduced into the nip of the rollers rapidly and at the correct moment.

Abstract: The proposal is for a novel process for automatically attaching a yarn to be spun to the end (37') of existing yarn in which the yarn end (37') is sought on the spool body (22) of a winding unit (7), a partial section of yarn (37) is unwound therefrom, drawn back against the spinning direction (S) by a fixed spinning unit (5) and laid laterally in the nip line (65) of the pair of delivery rollers (12, 12') of the drafting equipment (4). The clamped fibre strip (14) is released again and tensioned in a first step and removed from the spinning line (S) immediately after the drafting equipment while at the same time the partial yarn section (37) is prepared and kept in readiness beside the drafting equipment (14). In a second step, the prepared section of yarn (37) is drawn off again at operating speed and wound on and in a third step the partial yarn section (37) is laid in the nip line (65) of the pair of delivery rollers (12, 12'), the spinning unit is switched on again and the tensioned fibre strip (14) taken back to the spinning line (S) only once the yarn end (37') has left the nip line (65).
