Abstract

899,262. Stapling fibres. COURTAULDS Ltd. May 22, 1959 [April 25, 1958], No. 13169/58. Class 120(3) In a fibre-stapling machine, a continuous tow is fed through a nozzle as a flattened ribbon to helical blades of a rotating cutter. The nozzle has an elongated (outlet) mouth parallel to the axis of rotation of the cutter, internal guides running at right angles to the length of the mouth so as to resist lateral movement of the filaments, and one or more passages for entry of fluid and emergence thereof concurrently with the tow through the mouth. A lip of the mouth may form a stationary blade co-operating with the helical blades in a scissors action. The tow which is to be stapled may be supplied vertically downwards to a pair of feed rollers controlling the rate at which tow is supplied to a box containing the nozzle from which tow emerges into the path of the blades of an underlying cutter: compressed air is supplied to the box and the cut tufts of fibres are blown through a guide shoot, Fig. 4 (not shown). The nozzle shown in Figs. 1 and 2 comprises screw-connected blocks 1 and 2 forming a slot 4 communicating with a cavity 5 to which air is supplied via pipes 6, 7. Lips 10, 11, of guide pieces 8, 9, form a venturi orifice for flow of air from cavity 5, and ridges 12 help to align the tow and the air stream. Another nozzle, Fig. 3, comprises a bell-mouthed entrance to a tow guide 20, and air is supplied to each face of a chamber 21. Specification 375,356 is referred to.
