ABSTRACT:
An improved gill box with rotating heads, which comprises a plurality of needles acting on an assemblage of slivers fed substantially continuously and consists of a feeder group, a group which controls the fibers and is constituted by two heads with combs superimposed one above the other and rotating in cooperation, and a drawing group.
The gill box can comprise the following improvements: opposed rotating means to guide the ends of the combs; stationary guide-cam means cooperating in an intermediate position between the needle field and the rotating guide means; means to lubricate the rotating guides; means to feed and convey fluid under pressure into the zone of the outgoing sliver and inside every needle field; means to ensure a differentiated path of insertion of the needles into the sliver; means for a perpendicular and non-interfering withdrawal of the needles from the sliver; means for individual protrusion of the combs for better cleaning of the needles; pulling means always in phase with the rotating guide means; means to reduce angular play; and means to reduce the distance travelled by the outgoing sliver.
