1. spinning method that on drafter, adopts the suction roll of guider, wherein,, the very little fiber band of the twist, particularly from the rove (11) of a rove bobbin (12), perhaps drawing-off strip, be introduced into multistage drafting mechanism (13), so that finish the needed whole drawing-offs of the yarn count that is spinned there, this has finished the fiber band of whole drawing-offs, be output on the circumference of a roller (25) from the final gripping mouth (14) of drafter (13), do not add drawing-off ground through predetermined highway section (15), be transported to the resistance twist mouth (16) that air draught roller (25) and resistance twist anti-roll (27) are formed, from this point, through twist configuration, enter spinning equipment (17), wherein, along the circumferential direction, at least on sizable part of highway section (15), be provided with one than some radially air draught district (33) of fiber bandwidth at the excircle of suction roll (25), and along the highway section (15), by flowing into the air of suction roll (25) from outside to inside, produce a cohesion, make the fiber band that does not also add the twist through drawing-off, be condensed into the particularly ribbon closely (22) of the wide 1.5mm of being not more than, this spinning method is characterised in that:

  • In cohesion zone, highway section (15), inhaled air from the outside, particularly have sizable axial component, be introduced in the zone in highway section (15) of suction roll (25), the suitable inhaled air of (15) closing is pressed into a ribbon closely along the highway section to make fiber band.
