Tow or sliver drafting machine - has control elements disposed above needle bed comprising elastically retractable bristles

摘要

In a drafting machine or gill box for tows of slivers, a needle bed comprises bars supported by chains. Control elements for the sliver are disposed above the needle bed, and comprise a retainer device having a large number of elastically retractable bristles which are inclined in the direction of movement of the needle bed. The sliver control elements are introduced for the improved parallelisation of slivers, partic. where the fibres are short and bulky, and where fast running speeds on the machine are combined with high drafting.
