ABSTRACT:
The apparatus and the method of the invention dyes the yarn ends of a sheet thereof individually at predetermined positions along their lengths and manufactures tufted carpets therefrom in a tufting machine to provide a predetermined multi-colored complex pattern in the carpet. The invention includes pretreatment of the yarn in a wetting and cleansing bath, removing excess bath liquid in preparation for dyeing, synchronizing the yarn feed at the start with the feed to the tufting machine, simultaneous dyeing of pairs of adjacent yarn ends and separating them for delivery to the tufting machine in an arrangement to produce identical patterns side-by-side in the carpet.
