Also in this case, the treatment continues for a pre-set time.

- Figures 6 and 7 show further variants of the invention consisting of machines, each of which is made up of a tank container, above or inside which a single reel is set, the reel being motor-driven for feeding the cord fabric; a reservoir 48 containing the treatment liquid bath is in any case set inside the container. Also this, simpler, embodiment envisages crosswise movement of the reservoir with respect to the direction of feed of the fabric, so that the fabric will be set folded inside the reservoir as it drops vertically from the reel.
- the path of the reservoir may be either rectilinear, as in the examples given, or curvilinear, governed by special actuators, and its speed may be either fixed or variable. Variation in the speed of movement of the reservoir enables different types of folding of the fabric to be obtained, if the fabric proceeds at a fixed rate. Likewise, it is alternatively possible to have a fixed speed of translation of the reservoir, and the variation in the rate of feed of the fabric determines a variation in the length of the folds of the fabric in the reservoir.
- Motion may be transmitted to the tank by means of any type of actuator or motor device, whether mechanical, hydraulic, or pneumatic.

Abstract
Description
- The present invention refers to a compact machine for the treatment of cord fabrics, in particular for dyeing.
- In general, these types of machines enable various processes to be carried out, such as dyeing, bleaching, and washing of fabric. The said machines are made up of a tank-type container above which is set a motor-driven reel for movement of the cord fabric and within which a reservoir is set containing the treatment liquid dye. The cord fabric set so as to form a closed loop is made to rotate inside the machine in a single direction of rotation.
- Between the reel and the reservoir, nozzles are set which spray the treatment liquid at high temperature onto the fabric, which is set folded in the reservoir. The circulation of the cord fabric proceeds for a time necessary for optimization of the treatment.
- It is known that a machine of this type involves considerable time for treatment and, notwithstanding this, does not enable a perfectly treated fabric to be obtained. This is due, for example, to the fact that the so-called pile of the fabric, by setting itself in a fixed direction during processing, given the single direction of rotation, enables a fabric to be obtained with a good treatment in a single direction.
- It is also to be noted that in known machines this folded arrangement of the fabric is obtained by means of rod systems, which, albeit bringing about the folded arrangement of the fabric with a certain continuity, are not able to detect possible knots, tears, etc. in the fabric, and to stop the process in time.
- With the said machines, it is therefore necessary to repeat the treatment after reversing the looped fabric inside the machine, with a consequent increase in processing times and costs. In addition, a lengthening of the treatment times involves replacement of the bath, or, in any case, a continuous check on the latter, with the obvious need for topping up in the case of dyeing and bleaching.
- It is also known that existing machines which enable, instead, a treatment in both directions of fabric feed turn out to be particularly complicated in terms of construction and are hence costly, even though they operate well (see for exemple FR-A-2 681 615).
- A purpose of the present invention is to provide a compact machine for the treatment of cord fabrics, in particular for dyeing, which eliminates the problems concerning times and costs referred to above.
- A further purpose is to provide a machine in which the folded arrangement of the fabric in the bath is optimal, without the presence of complicated mechanisms, and in which it is possible to detect any defects and discontinuities in the cord fabric being treated.
- Yet another purpose is to obtain a machine which enables a considerable simplification of the component elements.
- These purposes according to the present invention are achieved by providing a compact machine for the treatment of cord fabrics, in particular for dyeing, as set forth in Claim 1. Further. characteristics are specified in the dependent claims.
- In such a machine, a reservoir is advantageously present, which is provided with a crosswise motion with respect to the direction of feed of the fabric, which makes it possible to fold the fabric both in the case where the fabric is moved according to a clockwise rotation and in the case where it is moved according to a counter-clockwise rotation.
- To achieve this, the reservoir is provided with a crosswise motion with respect to the direction of feed of the fabric, which drops vertically from the reel. The path of the reservoir may be either rectilinear or curvilinear, and its speed of motion may be either fixed or variable. The motion may be transmitted to the reservoir by means of a mechanical, hydraulic or pneumatic device.
- The structural and functional characteristics and the advantages of a compact machine for the treatment of cord fabrics according to the present invention may be better understood from the ensuing description, which is given to provide a non-limiting example, with reference to the schematic drawings attached, in which:
- Figure 1 is a cross section of a first example of a machine according to the invention taken along the trace I-I of Figure 2, in which the reels are set above the container;
- Figure 2 is a longitudinal section of a machine similar to the one illustrated in Figure 1, in which a number of turrets are provided that contain the reels and are set above the container;
- Figure 3 is an enlarged detail of Figure 2 illustrating a device for the crosswise movement of the bath to fold the fabric;
- Figures 4 and 5 are schematic views of a second embodiment of a machine similar to that of Figures 1 and 2, in which the reels are set inside the container, and the movement device is similar to that of Figure 3;
- Figure 6 is a section of a third example of embodiment of a machine according to the invention, in which there is a single reel set above and outside of the container;
- Figure 7 is a section of a fourth example of embodiment of a machine according to the invention, in which the single reel is set inside the container; and
- Figure 8 shows a top plan view of a multiple machine according to the invention.
-
- With reference first to Figures 1-3, a first example of a compact machine for the treatment of cord fabrics, made according to the invention and in particular used for dyeing, is presented. However, the same machine may be used also for other types of treatment, such as bleaching, washing and the like.
- The machine is made up of a tank-
type container 11, the top part of which extends in two protrudingseparate portions 12, 12' of a tubular type, in which twotowers 14, 14' set alongside one another are arranged by means offlanges 13. The saidtowers 14, 14', which are of a basically cylindrical shape, each contain onereel 15. Thereels 15 are motor-driven in both directions of rotation forfeeding cord fabric 17, which is wound so as to form a closed loop, and are connected together by apipe 18 equipped with twonozzles 19 and 19' to form a so-called "jet pipe". - The
nozzles 19 and 19' subject thefabric 17 to the action of spraying of treatment liquid at high temperature. Thenozzles 19 and 19' in fact are divided into two sets which operate according to the direction of translation of thefabric 17 inside thepipe 18 and are selectively fed byrespective pipes 20, which come from acentral manifold 21 supplied by a pump (not shown) and are equipped withclosing valves 22. Thetowers 14, 14' are moreover provided, on their sides, withinspection doors 23 which can be freely opened for arranging thecord fabric 17 that passes inside the machine.Doors 43 are also provided in thetank container 11 to facilitate arrangement of the fabric. Underneath each of thetowers 14, 14', within theprotruding portions 12, 12' of thetank container 11, conveyingcones cones 25 are moreover detached beneath thefirst cones 24 and are each provided with a cylindrical portion which extends downwards supported by anexternal closing wall 29 within theprotruding portions 12, 12', so as to identifychambers 30. It is to be noted how, inside the saidchambers 30, the treatment-bath liquid is introduced, fed in by a pair ofpipes 26 which come from a commoncentral manifold 27. As a result of the transfer, the bath liquid passes within thecones 25, impregnating thecord fabric 17. - The free end of each
second cone 25 is aligned with a length ofpipe 31, which has, towards its bottom end, a cross section shaped like an ellipse or a flattened circle, in a plane which is longitudinal with respect to the machine, and is designed to convey the fabric into anunderlying reservoir 48 set in thetank container 11. In the bottom part of thetank container 11, areservoir 48 is in fact provided according to the invention, the said reservoir having a hollow U shape extending for a dimension beyond a half-circumference of the container itself . - The
reservoir 48 moves inside thecontainer 11 with a motion that enables the fabric in the reservoir itself to be folded. A possible arrangement that enables reciprocating actuation of displacement of thereservoir 48 is illustrated in Figure 3 and consists of aworm screw 35, driven at one end by amotor reducer 36, which is located on thecontainer 11. Theworm screw 35 engages aninternal thread 37 which is fixed to an outer central area and is located above thereservoir 48. In this way, operation of theworm screw 35 determines displacement of thereservoir 48 according to a reciprocating motion. - In this connection it should be noted that on the
reservoir 48, at least laterally,wheels 32 are fixed on opposite sides, the said wheels running on twoguides 33 which are fixed to thecontainer 11 by means of asupport 34. - Thanks to the above arrangement, the
reservoir 48 is suspended inside thecontainer 11 in such a way that it can be displaced inside the latter. It is evident that the oscillating or to-and-fro movement of thereservoir 48 can equally be obtained by means of a pneumatic or hydraulic cylinder actuator, or by means of a direct motor reducer, with possible adjustment of their motion. - On the bottom of the reservoir 48 a pair of
suction openings 49, 49' are provided, which are set on opposite sides of thecontainer 11 and are connected to a bath-circulation pump (not illustrated). Also apipe 50 of the container for maintenance or discharge of the bath is provided at the centre. - Figures 4 and 5 show a second example of embodiment of a machine according to the invention, in which a pair of
reels 16 is set inside thecontainer 11. This is a machine consisting of a tank-like container 11, the top part of which directly contains a pair ofreels 16, the reels being motor-driven in both directions of rotation, for feeding thecord fabric 17, which is wound in closed-loop fashion. As in the previous example, between the reels 16 apipe 18 is set which is provided with twonozzles 19 and 19' and makes up a so-called "jet pipe". Thenozzles 19 and 19' spray treatment liquid at high temperature on the fabric. In points corresponding to thereels 16, at the sides of thecontainer 11, twoinspection doors 23 are provided, which can be freely opened for arranging thecord fabric 17 that passes inside the machine. Beneath each one of the tworeels 16, conveyingcones chamber 30. Thecones 25 are moreover detached beneath thefirst cones 24 and are each provided with a cylindrical portion which extends downwards and which, together with the walls of the containing box, defines the above-mentionedchamber 30. - It is to be noted how, inside the said
chambers 30, the treatment-bath liquid is introduced, fed in by a pair ofpipes 26 which come from a commoncentral manifold 27. As a result of the transfer, the bath liquid passes within thecones 25, impregnating thecord fabric 17. The free ends of thecones 25 have the function of conveying the fabric into areservoir 48 of theunderlying tank 11. - In the bottom part of the
tank container 11, areservoir 48 is in fact provided, the said reservoir being U-shaped or circular and extending beyond a half-circumference of thecontainer 11 itself. Motion is imparted to thereservoir 48, which moves in a basically crosswise direction with respect to the direction of feed of the fabric, inside thecontainer 11. This enables thefabric 17 to be folded inside thereservoir 48. - As in the previous example, actuation of the
reservoir 48 is the same as that illustrated in Figure 3, and the reader is referred to that description, the reference numbers being understood to be the same. - In the examples described and illustrated so far, the machine consists of a
single container 11 and asingle reservoir 48, but, as shown in Figures 2 and 5, machines having a number ofreservoirs 48 may be built. Thesereservoirs 48 are set alongside one another and are fixed to one another inside a singlelarge container 11, are provided with the same motion, and are able to treat even a number of cord fabrics simultaneously. In this way, for example, using the same circulation pump the bath is unified for all thereservoirs 48, thus making possible a considerable saving in costs and a uniformity of treatment of the various cord fabrics wound in loop fashion that are treated in the machine. - Figures 6 and 7 show how machines according to the invention may be made with a
single reel tower 14, or else directly inside the container. In any case, the invention envisages that themobile reservoir 48 should be set beneath the reel with respect to the feed of thefabric 17. - In the said embodiment with a
single reel fabric 17 is in a single direction. - In these arrangements with a single reel, the
pipe 18 provided with twonozzles 19 and 19', which makes up the "jet pipe", has also the function of deflecting the fabric away from the reel towards the opposite end of theunderlying reservoir 48. For this purpose, the pipe is set inclined between the output of thereel reservoir 48. - It is moreover possible, both in the case of reels set inside the container and in the case of reels set outside the container, to make distinct machines, each having one or more reservoirs, which are connected together so that they can work together and carry out the same type of process, or which are separate, and hence can carry out different processes. This enables optimization of production according to the batches to be processed.
- Figure 8 shows how a multiple machine may be built in which it is possible to treat a fabric 117 in the closed loop form or otherwise with different liquids or baths. Also in this case, rotation of the fabric may be in the clockwise direction or in the counter-clockwise direction. In fact, a set of
tank containers 111 contain pairs ofreels pipes 118 which criss-cross between one container and another and enable continuous circulation of the fabric. The ends of composite machines may be separate, so that it is possible to treat a cord fabric the ends of which are open, or else may be connected so as to treat cord fabric of considerable length but closed in loop fashion. The individual containers may contain different types of baths or the same type of bath and are thus able to perform any type of treatment. - There follows a brief description of the operation of the machine according to the present invention.
- In a first treatment step, for example dyeing, the
cord fabric 17 is fed into the machine via thedoors fabric 17 is treated in the clockwise direction. In this first step, thefabric 17 is conveyed by thereels pipe 18 where the set ofnozzles 19 is operated, which carries out a first forced treatment of the fabric with bath liquid. Next, thefabric 17, by means of thesecond reel first cone 24 and then within the second, underlying,cone 25. In this phase, the bath liquid present in thechamber 30, by its transfer inside thecone 25, subjects the fabric to a second impregnation. During treatment of the fabric in the clockwise direction, thereservoir 48 set inside thecontainer 11 containing the liquid bath is moving, so that thecord fabric 17, dropping vertically, is folded in the reservoir itself, as may be clearly seen in Figures 2 and 5. - In this phase the dye is aspirated and made to circulate inside the machine through the lateral or
central suction opening 49 set at the bottom of the container of the machine, so as to favour feeding of the fabric inside thereservoir 48. - Then the
fabric 17 goes back up passing inside the other twocones other chamber 30 which is transferred from thecone 25. This treatment consisting of the various impregnation steps referred to above proceeds for a pre-set time which is controlled by a central electronic equipment (not shown). - Subsequently, the electronic equipment operates the motor means that drive the
reels - The treatment is thus repeated with the sole difference that both the
set 19, 19' of nozzles present in thepipe 18 and thesuction opening 49' or 49 present in thecontainer 11 are actuated, so as to favour treatment and circulation of the fabric. Also in this case, the treatment continues for a pre-set time. - By means of a machine according to the invention it is therefore possible to treat cord fabric according to a plurality of operating steps in which the fabric is made to circulate in opposite directions automatically, without any need for intervention. The
pipes pipes 18, as well as thechambers 30, enable simultaneous operation of these devices with differentiated flow rates of liquid, thus facilitating treatment of the fabric. - The movement of the
reservoir 48 enables optimal arrangement and circulation of the fabric inside the machine. The advantageous provision of a reciprocating motion imparted to the cord fabric inside the machine according to the invention makes possible a considerable reduction in processing times and in production costs, as well as in the amount of treatment liquid bath used. - All this moreover means better and more uniform processing of the fabric, which, undergoing a surface treatment in opposite directions, is processed both with the pile and against the pile.
- The
fabric 17 may drop directly vertically and is not pulled, as, instead, happens when it comes into contact with special folding devices. The absence of contact moreover prevents any possible stretching of the fabric undergoing treatment. - Figures 6 and 7 show further variants of the invention consisting of machines, each of which is made up of a tank container, above or inside which a single reel is set, the reel being motor-driven for feeding the cord fabric; a
reservoir 48 containing the treatment liquid bath is in any case set inside the container. Also this, simpler, embodiment envisages crosswise movement of the reservoir with respect to the direction of feed of the fabric, so that the fabric will be set folded inside the reservoir as it drops vertically from the reel. - In any case, the path of the reservoir may be either rectilinear, as in the examples given, or curvilinear, governed by special actuators, and its speed may be either fixed or variable. Variation in the speed of movement of the reservoir enables different types of folding of the fabric to be obtained, if the fabric proceeds at a fixed rate. Likewise, it is alternatively possible to have a fixed speed of translation of the reservoir, and the variation in the rate of feed of the fabric determines a variation in the length of the folds of the fabric in the reservoir.
- Motion may be transmitted to the tank by means of any type of actuator or motor device, whether mechanical, hydraulic, or pneumatic.
