Abstract:
1. A beam dyeing machine, comprising: a vessel that can be closed; a beam in the vessel, positioned in a withdrawable manner, which is equipped for acceptance of a wound structure made of textile products, and which has at least one perforated tube in the area of its circumference; a liquor expansion and retrieval chamber which is connected with the inner space of the vessel through excess flow lines, and with a liquor circulation device consisting of a liquor circulation pump, which lies in a liquor circulation loop encompassing the textile beam and the vessel interior; and a pipe branching from the bottom side of the expansion and retrieval chamber; an injector connected to the pipe branching from the bottom side of the expansion and retrieval chamber, for sucking liquor from the expansion and retrieval chamber; and a pipe for transferring liquor from said injector into the textile beam; wherein the pipe branching from the bottom side of the expansion and retrieval chamber, the injector, and the pipe for transferring liquor, form a limited liquor circulation loop through the inner space of the vessel; and wherein the excess flow lines and the expansion and retrieval chamber are characterized in that the expansion and retrieval chamber is located directly in a section of the vessel, separated from the section of vessel containing the beam with the wound structure, further characterized in that the liquor circulation loop encompassing the expansion and retrieval chamber contains liquor transport/conveyance devices, and in that the liquor transport devices include said injector, the injection nozzle of which remains connected with discharge side of the liquor circulation pump and is connected at the suction side to the expansion and retrieval chamber.
