Drafting device for ring spinning machines, has pair of output rollers with output pressure roller and associated sub-cylinder, where compression zone is downstream to pair of output rollers

摘要

The drafting device has a pair of output rollers with an output pressure roller (2) and an associated sub-cylinder (3), where a compression zone is downstream to the pair of the output rollers. The output pressure roller is arranged opposite to a plane (13) towards a drafting zone (V) in a backward manner. The plane runs through the axis of the sub-cylinder and is perpendicular to a drafting unit plane (14). The drafting zone is kinked in downward manner.
