Abstract
A textile fiber drafting apparatus is disclosed, according to which the drafting bottom rollers in each line along the spinning units of a spinning frame are arranged in such a way that each two adjacently juxtaposed bottom rollers make a single block for each two spinning units, so that each bottom roller has an open, free end through which an apron may be replaced with a new one or fibers entangled on the roller may be removed with extreme ease. Between each such two spinning units is provided an arrangement for driving the bottom rollers thus disposed, including driving and driven mechanisms.
