Abstract

Apparatus comprising a closed circuit through which fabric moves in endless rope form driven by a winch (8) and a jet (10), is modified in that it includes two or more horizontal transport tubes (7a, 7b) forming a fast fabric run so as to allow for the simultaneous treatment of a fabric rope in each tube without causing entanglement. <IMAGE>

Description

APPARATUS FOR THE WET TREATMENT OF FABRICS This invention relates to an apparatus for the wet treatment of fabrics in contact with a treatment liquor, the fabric being disposed in endless rope form, being drawn by hauling means and circulating in an enclosed tubular circuit comprising a fast outward run and a slow return run, the major portion of the fabric being accumulated in the latter run, the apparatus being constituted by a storage and treatment chamber which forms a small angle relative to a horizontal plane; an end body attached to the chamber and tapering away from the chamber and a vertical terminal body attached to the chamber by a lower elbow portion and in which the hauling means is located.

Usually the apparatus of the type described are not capable of treating two or more fabric pieces simultaneously, since the pieces become seriously entangled, particularly during the fast outward run.

Consequently low production throughputs are obtained.

The apparatus according to the invention is characterised in that said fast outward run comprises at least two horizontal transport tubes, located at the same level be'ow tbc- storage chainUer and placing sad vertical terminal body ir. co;naunication with said taper;nir end oc'y.

The present apparatus, in comparison with others of the same type, provides the advantage of a very high production throughput, i.e. for the same operating time it affords a treatment capacity representing multiples of that Of the ordinary time.

Further advantages and features of the'invention will be appreciated from the following description in which, without any limiting intention, there is described a preferred embodiment of the invention, with reference to the accompanying drawings in which: Figure 1 is a schematic longitudinal section in elevation of the apparatus in the treatment stage for a textile material disposed in endless rope form.

Figure 2 is a schematic elevation view, partly in section, of the apparatus across the end provided with the vertical body attached by way of an elbow portion to the treatment chamber.

The present apparatus comprises a storage chamber 1 for an endless rope 2 of fabric submerged in a treatment bath or liquor 3. The chamber forms a small angle with the horizontal plane and is attached at one end thereof to an end body portion 4 tapering away from the storage chamber 1, while the other end is attached to a vertical cylindrical body 5 having a lower elbow portion Sa for attachment thereof to the chamber 1 and a top cover 6.

Furthermore, the apparatus comprises at least two transport tubes 7a, 7b horizontally located at the same level below the said chamber 1 and which penetrate inside the vertical body 5 at one end and communicate with the tapering body portion 4 at the other end.

The vertical body 5 contains the hauling means for providing continuous movement of the fabric 2 during the treatment. Said means comprises a winch 8 caused to rotate by a drive means and an overflow container 9 and jet container 10, connected to the tubes 7a, 7b, through an overflow port 11 and ports 12 respectively. Furthermore, said vertical body is provided with a fluidtight front cover 13 for loading and unloading the textile. material, such that such operations may be effected manually standing on the floor.

The transport tubes 7a, 7b are provided with a chamber 14 connected to a pump 15 for sucking the bath liquor 3 through a further chamber 16 provided with a heat exchanger.

The apparatus is completed by intercommunication means comprising an upper duct 17 connecting the vertical body 5 with the chamber 1, ducts t8 and 19 with respective valves 20 and 21 placing the containers 9 and.l0 in communication with the chamber 16, ducts 22, provided with valve 23 placing the transport tubes 7a, 7b in communication with the pump 15 and a further duct 24, provided with valve 25 and branches connecting various points at the bottom of the chamber 1 with the pump 15.

The chamber 1 forms the treatment zone for the fabrics 2 in the liquor 3 and therein there is accumulated the major portion of said fabrics disposed in vertical folds with a slow return movement.

The transport tubes 7a, 7b allow for the movement of respective fabric ropes 2 in fast outward circulation in flattenEd form.

The treatments may be effected cold or hot, pressurised or unpressurised and at different levels shown in Figure 1, there being a low level N1 in which the liquor 3 in the chamber 1 reaches half way up the textile fabric, an intermediate level N2 in which the liquor almost covers the fabric and a high level N3 in which the liquor fills the chamber. The tubes 7a, 7b are always filled with said liquor 3.

Generally speaking, the apparatus of the present invention behaves in a similar way to other apparatus of this type for the wet treatment of fabrics and the novel feature lies in the fact that it comprises two or more transport tubes 7a, 7b which operate simultaneously with respective endless fabric ropes 2 which, naturally, multiply the machine's production capacity.

The purpose of the chambers 14 in the end portion of transport tubes 7a, 7b before the fabric 2 reaches the treatment chamber 1, is to facilitate suction of the liquor 3 to provide for a slowing down of the speed of circulation of the liquor, thereby facilitating the particular arrangement of the fabric in the treatment stage in the chamber 1, i.e. in the slow portion of the closed circuit.

The small angle formed by the treatment chamber 1 improves the movement of the fabric in the said slow return run until it reaches the vertical terminal body 5 in which said fabric terminates the circuit and from the winch 8 starts out on the fast outward run aided by the overflow 9 and jet 10 containers.

Claims
