Abstract
Method of and apparatus for bundling fibers of a sliver in the drafting frame of a spinning machine in which a fiber-bundling zone is provided downstream of the last pair of drafting rollers. The fiber-bundling zone can be formed with a transporter for the sliver, e.g. a belt, provided with an array of perforations having a width which is at least equal to the traversing width of the sliver. The suction orifice juxtaposed with the array of perforations of the belt is inclined to the direction of the travel of the sliver and preferably extends over the full width of the traversing motion. The edge of the orifice can be rectilinear or curved.
