Abstract A nonwoven pile web is made from differently coloured pile yarns lying side by side, arranged so as to form a colour- figuration, and adhered perpendicularly in a sub-layer. Simultan- eously two rows of differently coloured yarn end portions having a length equal to a multiple of the desired pile height are arranged in the sequence of the desired colour-figuration, between which in cross-direction, and at a mutual spacing of two times the desired pile height, a number of threads extending parallel to each other and disposed in series of two and (having been impregnated with thermoplastic or latex paste) are pressed and joined. so as to form a continuous, multicoloured web. Subsequently the multicoloured web is cut in the direction parallel to the impregnated threads, and between the threads of each pair of impregnated threads, into a number of strips, and the next sections of each individual strip having a length equal to the desired width of the carpet web to be made, and a width equal to twice the desired pile height of said web to be made, are stacked and mutually connected on both edges along the adhered, impregnated threads, with a number of threads and/or a backing layer being provided with a thermoplastic or latex paste.
