ABSTRACT:
A novel fiber drafting system is disclosed, according to which fibers of sliver supplied continuously are passed through a first pair of rotatable cooperating rollers while being pressed and compacted into a reduced section by and between a space formed by a groove and a projection formed respectively in and on the circumferential peripheries of the rollers of said first pair. The sliver thus compacted is then transferred to and held by and between a second pair of rollers rotated at a higher peripheral speed than the first pair of rollers, whereby the fibers of sliver are drafted successively between the two pairs of rollers without use of conventional aprons for guiding and supporting the fibers in the drafting zone.
