Abstract: An installation is provided for the wet treatment of textile materials disposed on material-carriers, comprising a tank with means for loading or unloading the material-carriers, a means for causing the treatment fluid to flow through said materials and, possible, a heat exchanger, each material-carrier having a box shaped base with an aperture for connection to an aperture of an adjacent material-carrier, or for connection to a first pipe of said fluid moving means which opens into a treatment volume so as to form a first fluid flow in one direction, the flow of said fluid in the other direction following a path which includes at least a second pipe of said fluid moving means also opening into said volume, this latter being limited laterally by walls extending between the floor and the vault of the tank and said first pipe and at least said second pipe each open into said volume through one or more passages formed in the vicinity of the floor of the tank.

Abstract: A machine is provided for the liquid or gaseous treatment of textile or other materials having a material carrier and comprising, in a lower part thereof, a false bottom in which is formed a housing adapted to receive a heat exchanger, the false bottom defining a space or compartment with the bottom of the machine. A pipe having a vertical axis is mounted at the base of the machine, substantially in the axis of the latter. The space may be either isolated from the rest of the machine, or placed in communication with the upper part thereof through external or internal ducts, and inert bodies may be provided in the machine.
