Abstract: Apparatus for randomly coloring a pile fabric material includes a preconditioning unit for pretreating the fabric to be dyed with a wetting agent, a conveyor for conveying the pretreated fabric continuously through a series of operating stations including a gum applicator for application of a viscous gum coating and thereafter to a roll dye applicator for application of a first dye color which penetrates the gum coating prior to being set. The first dye color is of a relatively low viscosity, much lower than that of the gum, to allow said dye color to overrun the tips of the yarn. The tips of the yarn remain relatively undyed by the first dye color which settles mostly at the lower base position of the carpet yarn.For application of additional dye colors, additional successive dye applicators may be used. In such event the dye colors applied are different visosities. The first applied dye color is preferably of a viscosity greater than that of the second applied dye color and may be included within the gum.

Abstract: A flexible carpet web having a plurality of spaced apart pressure sensitive adhesive segments disposed in a patterned relationship on the backing thereof, and in which the same are preferably patterned according to certain given parameters involving the relation of the total area of the adhesive segments to the weight and/or the area of the carpet web, the spacing between adhesive segment centers as related to the area of the adhesive segments, and/or the spacing apart of the adhesive segments in relation to the configuration thereof; and a method of manufacture of a carpet web having adhesive segments applied to the backing thereof for facile installation thereof.

Abstract: A continuous process and apparatus for randomly coloring a pile fabric material includes pretreating the fabric to be dyed with a wetting agent, conveying the pretreated fabric continuously through a series of operating stations including a gum applicator for application of a viscous gum coating and thereafter to a roll dye applicator for application of a first dye color which penetrates the gum coating prior to being set.

The tips of the yarn remain relatively undyed by the first dye color which settles mostly at the lower base position of the carpet yarn.For application of additional dye colors, additional successive dye applicators may be used. In such event the dye colors applied are different viscosities.

Abstract: A method for preparation of the final film used for engraving a flat screen, belt screen or rotary screen for a printing machine. The final film is prepared from a photograph of the image to be reproduced and engraved by known techniques on a screen so as to provide a continuous repetitive pattern on the face of a pile fabric dyed in a continuous print dyeing process.Select areas of photographic images are montaged and put into a repeat pattern within a predetermined outline to establish the basic repeat. Four continuous tone color separations are made of the selected pattern to provide yellow, blue, red and black continuous tone negatives which represent the four colors of the original image. Each color separation is posterized and half toned to provide eight positive films. The films are selectively combined, blown up to the desired repeat size to provide a negative or positive which is used to prepare a flat bed screen or rotary screen for an otherwise conventional printing process.
