Abstract: A process of dyeing by deposition of spots of dyebaths of different colors on moving filaments, in a series of application stations, by abrupt cyclic or pseudo-random interruption of the deposition in the application stations, and a device for practicing this process. The process is characterized in that, in each application station, the moving filaments are abruptly taken out of contact with the dyebath by a linear or pseudo-linear actuating device acting on the dyebaths or on the moving filaments. The invention is more particularly applicable to the field of the textile industry, in particular the treatment of filaments, particularly by dyeing of the “spaced dyeing” type.
