Abstract: A powder dye extraction apparatus has an extraction screw with a hollow shaft which receives a push rod. A dye discharge door in the form of a perforated plate is mounted on the end of the screw and delivers powdered dye as the screw is rotated. A scraper is mounted externally of the aperture plate and rotates with the screw to pulverize the powdered dye as it is discharged. An end of the push rod extends out of the screw and carries a lid which is retractable over the aperture plate and scraper.

Abstract: The invention discloses an apparatus for the preparation and distribution of dye solutions to a dyeing apparatus or to a color kitchen, including a unit for the loading of powder-dye into dissolution vats, a collector unit for conveyance of the dye solution to a distributor unit and for pipe flushing, and a distributor unit. The collector unit consists of a selection-plate, which alternatively connects the distributor unit with the dissolution vats or with a flushing water-network, wherein the distributor unit consists of a plurality of outlets supplied by the collector unit, through a rotary collector, the outlets being connected with the dyeing equipment or with the color kitchen, or with sewers.
