Abstract

<PICT:0740902/IV(c)/1> <PICT:0740902/IV(c)/2> An apparatus for the spraying of textile materials with liquid comprises a spray nozzle mounted within a conduit through which the textiles are passed and in which they are directed downwards onto its floor so that any surplus liquid is removed by the passing materials. Figs. 2 and 3 show a spraying plant comprising a horizontal square conduit 12 through which wool is passed under the action of an air-stream drawn through by an extractor fan. The conduit is first constricted by two adjustable plates 13 which are pivoted about a horizontal axis, this being followed by two atomizing nozzles 23 to which the spraying fluid is fed, the supply system using compressed air as described in Specification 740,889. Ahead of the nozzles is situated a downwardly inclined baffle plate 26 which restricts the conduit to about one quarter of its normal cross sectional area so that the textile material is carried by the air flow along the floor of the conduit and so absorbs any surplus liquid which may have fallen there. The baffle plate 26 is pivoted and counterweighted so that it may compensate for surges in the air stream and it may be manually adjusted for minimum closure. Additional air is let into the conduit via adjustable flap 37 and adjustable openings in the side walls of the conduit. A removable electric light fitting 33 is mounted over an access port 34 and a transparent sight screen is arranged in the side wall.
