Abstract (en)

A three line type drafting device wherein first, second and third sets of drafting rollers (4 and 5, 6 and 7, and 13 and 16) are provided. The middle (second) set of rollers (6 and 7) are both constructed as apron rollers. In the back (third) set of rollers, the top roller (13) is constructed by an apron roller, while bottom roller (16) is constructed as a fluted roller. A guide plate (41) is arranged between the middle bottom and back bottom rollers (9a and 16) and is made to contact, at its top surface, with a lower side of the apron (14) of the back roller set. A desired control of floating fibers is obtained at a back drafting zone between the middle and back sets of rollers (6 and 7; and 13 and 16), while a desired total drafting ratio is obtained between the front and back set of rollers (4 and 5 and 13 and 16) without being influenced by inevitable variation in thickness of the apron (14) at the back roller set. <IMAGE>
