Abstract
This invention relates to a device for distributing textile fiber slivers inside collection boxes in spinning preparation machines, in particular in drawing frames. The device according to the invention comprises a plate rotating above the collection box and containing an eccentric outlet connected by a duct fixed to the plate to a substantially axial inlet which faces guide calendars for a sliver leaving a spinning preparation machine; the duct is formed by two tubular portions, which are partially inserted in one another and form a cylindrical passage external to the portion defining the duct inlet. In this manner the sliver is guided delicately by a cushion of air centrifuged towards the duct outlet and the friction due to rubbing of the sliver on the duct in proximity of the duct outlet is reduced to a minimum.
