Method and apparatus for bundling of a in a drafting arrangement of a spinning machine drafted fiber composite

摘要

The present invention relates to a method and a device for bundling of a in a drafting arrangement 1 of a spinning machine drafted sliver 2, which in the connection to the drawing in of a fiber bundling zone 3 and combined to form a yarn is twisted together, with which a pair of output rollers 10 of the drafting frame 1 and the fibre bundle 2 over the length of the fiber bundling zone 3 a transversely to the direction of transport directed suction air stream and subjected to during the bringing together by means of an essentially flat, perforated conveying means 15 is supported on one side. The suction air stream acts approximately in the width of the desired bringing together by at least one suction opening 20 and through the transport means and onto the fibre structure. According to the invention, the fibers of the fiber strand 2 in the area of the suction opening 20 is moved at least partially inclined to the direction of transport, combined and compacted.
