In an needle bar drawing device or gill box comprising needle bars carried by chains is arranged a bristle mat consisting of one or few layers of bristles extending along the whole needle field up to the proximity of a clamping gap formed between a pair of exit rollers. The bristle mat is penetrated by the needles of the needle field and creates a stripping effect at the disappearing position of the needles in the region of the nip, this stripping effect avoiding the conveying of fibers freely swimming in the sliver, and thus the danger and disadvantage of any lap forming.

Needle bar drawing device

The invention concerns a needle bar draw frame or gill box with a needle field or gilling area of needle bars carried by chains. With the aim of attaining the usual performances in respect of speed and drawing ratio at the same quality also in the case of voluminous short-staple slivers with draw frames operating with an upper and a lower needle field, control means engaging from above into the needle field are used in a draw frame provided merely with a lower needle field. These control means are constructed as bristle-like holding down devices which are arranged particularly immediately upstream of a pair of drawing rollers and possibly shortly downstream of a pair of entry rollers, while the central region is controlled in the usual manner by a bar roller or bar chain.
