    (54) Device for obtaining the roving in a finisher


    (57) This invention relates to a device for compacting a bundle of fibres into a roving at the delivery side of the drafting assembly (10) of a finisher, wherein said device comprises in its front part a condensing slot (20) for the bundle of fibres and said slot ends with a semi-circular profile, from which extends a spindle (22), around which the bundle of fibres winds and wraps itself so that it assumes a substantially circular shape. In the slide duct (28) for the bundle of fibres, immediately following the said spindle around which the fibres wind, there are provided two or more nozzles (24) which inject air into the slide duct (28) for the fibres in a very sloping direction in the feed direction of the ring of fibres and in the tangential direction with respect to the axis of the said slide duct, thereby substantially effecting the axial feed of the said ring of fibres.
    In the end part of the slide duct (28) for the bundle of fibres, following the said nozzles (24), there are two or more nozzles (26) which inject air in a slightly sloping direction in the feed direction of the roving of fibres and in the substantially radial direction with respect to the axis of the said slide duct in order to compact the ring of fibres into a roving suitable for being supplied to the cop (18) being formed, on to which it is wound.
