Abstract
717,664. Preparing fibres for spinning; drawing-apparatus. BONSER, A. Feb. 22, 1951 [Feb. 22, 1950; Aug. 9, 1950], Nos. 4507/50 and 19760/50. Classes 120(1). 120(2), and 120(3) Impurities in textile fibres are disintegrated by attenuating a sliver substantially into its component fibres, arranged in parallel relation with little mutual overlay, and subjecting the fibres in this condition to the action of crushing surfaces one or more of which is grooved to allow the fibres to lie in the grooves without being acted upon by the portions of the surfaces separating the grooves which operate to crush impurities, thereby preventing damage to the fibres by the crushing surfaces, and subsequently condensing the fibres into web form. As shown, sliver a from an intermediate feed or other source passes between conveyer rollers b revolving at a surface speed similar to the speed of feed of the sliver, between endless control bands e which exert a slight drafting action on the sliver, and thence between crushing rollers f which rotate at a surface speed sufficiently greater than bands e to attenuate the sliver so that the fibres thereof are parallel to one another without being appreciably overlaid by other fibres. One or both of rollers f have, except on their end portions, annular or helical grooves of a width and depth approximating to or slightly larger than the diameter of the fibres so that the fibres can position themselves in the grooves while impurities are subjected to the crushing action of the rollers which are suitably loaded. A slight reciprocating axial traverse between rollers f may be provided. From rollers f the fibres pass to a card-clothed roller g rotating at a surface speed suitably higher than that of rollers f, and thence to a condensing roller h rotating at a surface speed approximating that of conveyer rollers b. The fibres condensed into web form are stripped from roller h by a roller k and passed forward by a pair of compacting rollers n The sliver to be treated may be split up into separate parts which are treated in parallel, and a magnet may be used to remove ferrous material. More than two crushing rollers may be used; these rollers may be heated, and oil, water, colloidal silica &c. may be added and dispersed by the action of the roller. Control bands e may be replaced by a gill box or boxes, and rollers g, h and k may be replaced by a swift and doffer. According to the first Provisional Specification the fibres may be reconstituted into sliver form by passing them between two endless bands travelling at a low speed; the bands may converge and may be clothed with card wire. Also crushing rollers may be provided with card teeth or may be replaced by plane surfaces on roller segments. According to the second Provisional Specification, the fibres may be reconstituted into sliver form by subjecting them, on leaving the crushing rollers, to a cuttling action to lay them in a succession of superposed folds on a suitably traversed conveyer belt so that the resulting mass may correspond to the thickness and density of the sliver before treatment. Specifications 634,388 and 650,029 are referred to.
