` In Switzerland April 15,1931 'f 1 Claim. '(Cl.. 8719) The present invention relates to a new and improved dyeing machine for textile fabrics and more especially to that type of dyeing machine which is known asa' jigger.
With the hitherto known jiggers for the dyeing of webs of fabric the disadvantage hasV existed thatwith direct positive4 winding up of the fabric, the tension to which the fabric had to besubjected was too great, and fragile fabrics were und'ulystrained and'very frequently damaged. The
speed of the fabric and with 'it the tension on the fabric was furthermore not constant; creas-v ing frequently took place in both longitudinal and transverse directions of the Web.l
The object of the present invention is to overcome these defects and this is attained by causing the Webs of fabric at no point of its passage through the vat being exposed to any appreciable tension.
Veyed by a drum running in the vat and driven by a motor and is taken up by a rolling-on reel the position and circumferential speed of which isso chosenwith respect to the feed of the fabric that the circumferential speeds of the unwinding and the winding up reels are the same and separate guiding devices for the conveyor drum and the said reels `are used so that the fabric is not subjected to any detrimental degree of tension or stretching.
' All rollers, drums and the like with which the material comes into contact have a special drive without the'fabric being utilized in any way for this purpose, or being stressed with the result that the finest and most fragile fabrics can be dyed without being injured.
Two embodiments are shown, to some extent diagrammatically, in the accompanying drawings and by way of examples:
Fig. l shows a jigger with hydraulic drive, in side View, partly in section.
Fig. 2 is an end View with some parts in section.
Fig. 3 shows a hydraulic driving motor in section and is taken on the line A-A of Fig. 1.
Fig. l shows a second form of construction with friction wheel drive, in side elevation.
Fig. 5 is an axial section of the same machine.
Fig. 6 shows diagrammatically the Working process.
A drum I of comparatively large diameter is fitted on a shaft 2 (Figs. 1-3) which is rotatably carried on ball bearings 3 in the machine frame. The drum I is driven through toothed wheel and chain drive 5, 5, l, 8 by a Water turbine 9 or9a. The wheels of the turbines 9, 9a driven by means According to the invention, the fabric is con? of 4water jets are providedwith oppositely directed bladesV which permit an alteration of direc'- tion of rotation of drum I, the one or the'other being used for driving. A reversible electric motor;l not shown, a'. compressed air motor, or a Weight motor or the like could be provided, in any case onlysuch means for driving are used which allow the direction of rotation to be altered' and ensuring a steady elastical drive; Water is supplied by `a pipe 20 andinozzles directing jetsf on to the wheels ofsaidturbines 9, 9a. vValves are arranged in said pipe 2li-to direct the flow of-water to any of said turbines.
Alongside the drum I", and parallel thereto there are fitted in'ball bearings I2 both a rollingV up and a rolling-off reel lli, I I by means of shafts I3. The bearings are slidably mounted' inslots of the frame running radially with reference to the druml I. The-'reels I0, II 'are'` mounted in such a `manner that the reels Anevercome into contact with the drum I. The reels IIi,` I I"als'o are of Vlarge diameter, andz are easily rotatable on the ball bearings I2'i` A Y` On eachofthe shafts I3 there are two water Wheels I4 one onr each -endl (or a fan or electro-` motor couldVV be` usedf for pneumatic orV electric drive respectively).`
The drum I is driven byone orthe other turbines 9 or 9a, and by varyingthe quantity of'water flowing through', the torque andtthus'the speed at which the fabric passes the machine can be very easily regulated. The water under pressure used furthe drive is, Vaftergiving up` its power, caught at the outlet of the respective turbines in the pipes 2I, 2Ia. In these pipes 2I, 2 Ia, there are light load or overflow connections as 22, which are controlled by regulating cocks 23. These regulating cocks 23 serve to regulate the flow of water to the water Wheels I4 constantly for the rolling-up reel only, and to thus exactly adjust the rotation of the rolling-up reel that the fabric fed by the conveyor drum I is very loosely rolled up Without undergoing tension or stretching. Preferably, the water acts up-on the blades I4 only by gravity.
Slip couplings could also be used in the driving of the reels in order to be able to transmit a definite turning moment capable of adjustment.
1 In order to ensure a uniform dyeing of they length of fabric on the machine even with the 50 most moderate size dyeing bath, and in order to rapidly dye material not easily permeable, by squeezing in the dye, three very light rollers 25, 26, 21 made to float, are arranged easily rotatable in the trough 24; the floating roller 21 is so arcording to experience, the warp threads shrink material, since it is carried over the roller 2, is
held from the drum I, thus giving the dye liquor better access to the fabric length.
In the dyeing of fabrics, as for example crepe and the like, these on becoming wet vat once shrink in length and width. Even with a Smau pull on the fabric caused, for example, by the resistance of the ball bearings or the friction in the dye liquor, creases are produced. In vorder to prevent this creasing, a spreading device: 28, 29, 3D is fitted in front of each fabric reel and in such a manner that this immerses wholly or partially into the dye liquor. Each spreading devicerconsists of two pairs of very light cone rollers 28-30, with the greatest diameter in the point of contact in the centre of the path of the fabric web, and of two pairs of cone rollers 29 which are fitted on a` bent and rocking spindle, the greatest diameter of the cones being at the outside on the edge of the fabric length. Spreading devices of this type are well known, any suitable device can be used.
The cone rollers can be adjusted as desired with respect to each other in order to adjust the embracing arc to the desired spreading out effect. The cones 29 here work as spreaders of the weft threads, and the cones 28, 29, 30, serve to smooth out the uneven warp thread lengths. Ac-
more on wetting at the edges of the material than in the centre of the fabric lengths.
It is of great importance for a successful result that the free fabric running on or running off the course indicated by line a and b between the fabric reel and the spreading out device or the fabric reel and the conveyor drum be as short as possible. In order that this may be attained, known mechanical hydraulic or other means may be used in order to move upward or downward the` reels I0, II in the direction of arrows c. radial to the conveyor drum I, the reels Ill, II
' never, however, being adjusted so low that they 501.1
come into contact with the conveyor drum I duringthe working process 'of the machine. The distance of the reel from the conveyor drum I is regulated according to the quantity'of fabric on the reeling up or unwinding reel.
With electric drive, both the conveyor drum I and the running reels I9, II are driven by means of synchronous three-phase motors, the speed of which may be regulated by known means such as speed reducers, regulating resistances, and the direction of rotation of which may be altered by current reverses.
With the machine with mechanical drive (Figs. 4 and 5), the drive of the reels I0, I I, takes place from the shaft 2 through the toothed wheel gear I5, I9, I'I, and friction discs I8, which are arranged on both sides. The fabric reels IIJ, II are driven through friction discs I9 which bear, according to the angle of inclination, with more or less pressure against the friction discs I8 by their own weight. The rolling-olf reel tends to be always raised by the friction disc I8 and is freely rotatable in ball bearings I2, rotating with minimum unwinding resistance which permits a high speed of the fabric length and consequently a large Output from the machine. The transmission ratio between the shaft 2 and the friction disc I9 is slightlyY greater than that of the circumferences of the conveyor rollers I and of the fabric reels I9, I I when the latter is empty.
yWhat I wish to claim and secure by U. S. Letters Patent, is:-
In a dyeing machine fortreating textile fabrics with liquids, comprising a container adapted to receive the liquid to treat the fabric, a positively driven feed drum larranged to immerse in the liquid in said container, two rollers disposed at both sides of said feed drum, separate and resilient means to drive said feed drum and each of ,said rollers, means to adjust the driving torque of said drum and of each of said rollersA not to exceed a predetermined tension on the fabric, `two buoyant cylinders within said container and disposed below and on both sides of the said feed drum, a frame, guide ways in said frame for said cylinders, the guide ways running in radial direction to said drum, an idle roller arranged between said cylinders at a distance from the mantle of thefeed drum, means to reverse the direction of rotation of each of said rollers and of said drum, the said rollers being arranged to be close to but out of the liquid when fully wound, and a spreading device for the fabric arranged intermediate the drum and each of the rollers.
