Abstract

An apparatus for stamping with dye jets, intended to apply liquid dye on a porous material, such as a pile carpet or hair carpet tiles or plates, to form a pattern thereon, having a plurality of discharge orifices of dye disposed in at least one row through a path along which the material is to be advanced, while streams of liquid dye are continuously being discharged from these orifices, and in which each dye discharge orifice has associated therewith is a nozzle connected to a supply of compressed gaseous fluid, such as air, through an electromagnetic valve governed by a pattern-forming control device, so that, when either valve is open, it will be discharged a stream of gaseous fluid from the corresponding nozzle against the dye stream coming from the associated dye discharge hole, so that it deflects this dye stream in such a direction that it does not impinge on the material, while, when the valve is closed, said dyeing current will impinge on the material to stain part of the drawing on it, characterized in that the valves electromagnetic devices that govern the supply of gaseous fluid to the nozzles of the or each row of dye discharge orifices are mounted on support means in one or more groups, the magnetic axes of the valves of a group being located in a common plane and being oriented in this plane so that the magnetic axis of each valve of a group is inclined with respect to straight lines interconnecting similar points of that valve and of its adjacent valves closest to the group forming an angle or angles of between 35º and 55º .
