in the pile yarns each applicator unit of the applicator assembly further has a dye pick up roll 80 for delivering a uniform film of liquid dye to a coacting doctor blade 81 each having a multiplicity of inclined v cross section gutter extensions 82 by means of which the liquid dye is divided into multiple separate streams or drippings 83 some or all of the gutter extensions 82 may be equipped with flow control plugs whereby the flow from certain gutters may be regulated or stopped completely in the interest of varying the random color pattern for the carpet below the opposing sets of gutter extensions 82 a power driven endless flexible conveyor element 85 such as a sprocket chain carries plural evenly spaced cylindrical horizontal axis stream cutters or interruptors 86 which travel continuously beneath the outlets of the gutter extensions 82 in two horizontal passes moving in opposite directions transversely of the line of movement of the carpet web 12 the moving elements 86 constantly travel through the falling dye streams 83 and cut or interrupt the same so that the drip pattern of the liquid dye is completely random irregular and widespread across the pile face of the horizontally moving carpet web below the stream interruptors 86 stationary inclined combs 87 further intercept and break up the falling dye streams 83 again for the purpose of rendering the drip dye pattern completely random non uniform and non repetitive on the carpet pile face if desired the comb elements 87 which are pivotally mounted can be flipped outwardly from their active positions of fig3 to inactive positions clear of the falling dye streams fig4 7 illustrate the manner in which dyeing of the pile face 16 is effected as shown in fig4 the viscous gum coating.
