Abstract: A machine for the liquid or gaseous treatment of textiles or other fibrous or porous materials, which comprises a partition (9) located in its end zone opposite its cover (2), which partition (9) forms, with the bottom of the machine (1) and the corresponding part of its side walls (14), a leaktight box which delimits an expansion zone for the treatment fluid, that part of the machine which is located between the cover (2) and the partition (9) forming the actual treatment zone (10), which accommodates at least one holder for the material, the machine further comprising a device for the circulation of the treatment fluid.

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.
