Abstract
The object of the invention is to facilitate the entry of a fiber band into a drawing machine. The invention is comprised of a fiber band insertion apparatus having a combination condenser and guide device with a longitudinal slot extending over its entire length. The guide device is followed by roll pair, which, at least during the laying in of the fiber band, has an accessible entry opening. This opening is at least partially formed by a recess in at least one of the opposed sides of the roll pair. The recess is separated by a flange on one of the circumferential rim surfaces which are mutually profiled to provide space for a compression line for the fiber band. The entry opening of the roll pair and/or feeders, as well as the entry slot of the condenser are, essentially, arranged in a common plane. With the aid of the invented apparatus, the fiber band is laid into the band entry device by a movement transverse to the normal transport direction of the fiber band when the drawing machine is running.
