Abstract: An apparatus for dyeing textile materials is provided that includes one or more chambers for dyeing and one or more storage baskets. The apparatus has a first station with a container hydraulically connected with the chamber. The first station is for the drawing and metering of dyeing solutions and for the admission of the dyeing solutions into the container to feed the chamber for dyeing the material disposed inside the storage basket. A second station has a stirrer. The basket is connected in a stable but removable way to the stirrer. The basket is located in correspondence with the chamber.

Abstract: A beaker for a sample dyeing machine comprises a hollow beaker body and a longitudinal sliding cylinder with flanges on both its ends. The outer wall of the cylinder is uniformly perforated for wrapping of a sample yarn or cloth to be dyed. A plurality of grooves is separately formed on the periphery of either one of the flanges to guide the flow of a dye solution. An annular passage is formed in the interior of the cylinder from one end to the other for allowing a dye solution to flow between the passage and the perforated wall of the cylinder. The beaker thus constructed can dye a sample uniformly and efficiently due to sufficient contact between a sample and a dye solution. The beaker also comprises a hollow tube outside the beaker body for one-way flow of a dye solution, and/or a dispensing device screwed on the top thereof for liquid addition to the beaker. A sample dyeing machine comprises a plurality of the beakers in a fixed rack.

Abstract: A treatment device (100) for a textile web (1) comprises a drum (20), rotatable in a container (2) with a treatment liquid (4), around which the web (1) is wrapped. The ends of the drum (20) are supported on bearing plates (10) arranged near the fronts of the container (2). The bearing plates (10) are supported at the upper end on an eccentric (6), opposite the lower end of which there is a torque support (9). As the eccentric rotates, the bearing plates (10) with the drum (20) and the web (1) wrapped around it are caused to oscillate in the treatment liquid (4).

Abstract: Apparatus for dyeing textile materials with a fixed, hollow and substantially cylindrical body intended to contain a dyeing bath consisting of water and dyeing substances in predetermined proportions, comprising in combination:--a basket for holding the materials to be dyed, whose side wall is provided with a plurality of ports or openings for the communication of the basket with the cavity of the body, and with upper and lower bases being provided with corresponding ports or openings, the basket being locatable within the cavity of the container and a transmission driven by a corresponding driving member and connected to the upper base of the basket for the vertical reciprocating movement thereof.
