' OPEN WIDTH DYEING MACHINE WITH PERFORATED CYLINDERS g Filed Oct. 14, 1950 s Sheets-Sheets INVENTOR. Hermann Hugs BY mum-WM Patented Mar. 25, 1952 OPEN WIDTH DYEING IMACHINE WITH PERFORATED CYLINDERS Hermann Haas, Remscheid-Lennep, Germany Application October 14, 1950, Serial No. 190,124 In Germany January 30, 1950 This invention relates to machines for treatin a web of cloth in open-width form to the action of some desired liquid, which may be a dye liquor for dyeing the cloth or a washing fluid for washing the cloth.
One known means for thus treating a web of cloth in the open-width form is to pass the web around and in contactwith a cylinder or tube having perforations, and to force the liquid with which the cloth is to be treated through said cylinder or tube and through its perforations.
If the liquid is drawn through the perforated cylinder by suction, the lowered pressure in the cylinder will cause the cloth to be held firmly against the perforated portion of the cylinder, thereby making it necessary to apply a strong pulling force to the cloth in order to feed it forward.
On the other hand if the liquid with which the cloth is to be treated is forced into the cylinder and outwardly through its perforations by pressure, it is necessary to subject the, cloth to considerable tension in order to hold it in contact with the perforated portion of the cylinder and to prevent it from being forced away from the cylinder by the pressure of the liquid flowing outwardly through the perforations.
subjecting the cloth to the necessary tension to move it over the cylinder when the liquid is being drawn through the cylinder by suction, or to hold the cloth in proper contact with the perforated cylinder when the liquid is being forced under pressure into the cylinder, is likely to deleteriously affect the cloth.
It is therefore one of the objects of the present invention to provide a construction by which the portion of the cloth which is in engagement with the perforated cylinder is maintained in contact therewith with a gentle touch and under no harmful tension.
In order to give an understanding of the invention I have illustrated in the drawings some embodiments thereof which will now be described, after which the novel features of the invention will be pointed out in the appended claims.
In the drawings,
Fig. l is. a longitudinal vertical section through amachine for dyeing cloth embodying my invention.
Fig. 2 is a side view of the dye vat shown in Fig. 1 looking toward the observer.
2 Claims. (Cl. 68-175) Fig. 3 is a section on the line 3-3, Fig. 1.
Fig. 4 is a fragmentary sectional view on the line 4-4, Fig. 1, showing one of the perforated cylinders around which the cloth is passed.
Fig. 5 is a view similar to Fig. l but showing an adaptation of the invention designed for washing cloth in open-width form rather than dyeing the cloth.
Fig. 6 is a side view of the machine shown in Fig. 5.
Fig. 7 is a diagrammatic view illustrative of the different size of cloth feeding rolls which are used for feeding the cloth through the liquidcontaining vat and around the perforated cylinders.
Referring to Fig. 1, I indicates a die vat containing dye liquor and 2 indicates the web of cloth in open-width form which is to be treated by the dye liquor in the vat l.
Situated within the vat I and submerged in the liquid therein are a plurality of stationary horizontal perforated cylinders, four such cylinders being herein shown and being indicated at 3, 4, 5 and 6 respectively. H
These cylinders may be supported in the dye vat l in any suitable way and as illustrated in Fig. 4 each cylinder is provided with end. or head members 1 which are rigidly secured in any suitable way to the side walls 8 of the vat l. The lower portion of each cylinder 3, 4, 5, and 6 with which the cloth 2 contacts is perforated as shown at 9, but the upper portion with which the cloth has no contact is imperforate.
Means which will be presently described are provided for forcing the dye liquor in the vat l into each cylinder under pressure so that the liquid is forced outwardly from each cylinder into the dye vat through its perforations 9.
The cloth 2 is held against the perforated portions of the cylinders 3, 4, 5 and 6 by horizontal idler guide rolls which are parallel with the stationary cylinders and are located within the vat l and above the perforated cylinders. A pair of such guide rolls is shown between each two adjacent cylinders. The pair of guide rolls between the cylinders 3 and 4 are indicated at l0, those between the cylinders 4 and 5 are shown at II and those between the cylinders 5 and 5 are shown at l2.
The cloth is fed forward through the dye vat and around the perforated portion of each cylinder by means of driven cloth-feeding rolls [3, i4 and I5 which are parallel to the guide rolls. All of these cloth feeding rolls are shown as located within the vat l below the stationary perforated cylinders, and one of the feed rolls is situated to act on the length of cloth between the guide rolls of each pair.
As shown in Fig. 1 the section it of the cloth between the guide rolls l0 passes around and is acted on by the feed roll I3, while the section I! of the cloth between the guide rolls H passes around and is acted on by the feed roll M and the section 18 of the cloth between the guide rolls l2 passes around and is acted on by the feed roll IS.
The cloth is fed into the vat over a guide roll l9 and is delivered from the vat at the other end thereof by means of a delivery roll 20. The stationary cylinders 3, 4, 5, and 6 have a tandem arrangement, and there is a guide roll above and on each side of each stationary cylinder, said guide rolls serving to hold the cloth in contact with the preforated portion of each cylinder.
There is also a driven feed roll between each two adjacent cylinders, which feed roll takes the cloth from the output or delivery side of one cylinder and delivers it to input side of the other cylinder.
There is also a pair of guide rolls for each feed roll, said guide rolls serving to hold the cloth in contact with the feed rolls.
The driven roll l3 takes the cloth from the stationary cylinder 3 and delivers it to the stationary cylinder 4, and the guide rolls l0 serve to hold the cloth in contact with a large portion of the surface of the feed roll.
Similarly, the feed roll l4 takes cloth from the output side of the stationary cylinder I 4 and delivers it to the input side of the stationary cylinder 5, the guide rolls ll serving to hold the cloth in contact with the feed roll M.
One of the guide rolls H3 together with one of the guide rolls I l serves to hold the cloth in contact with the perforated cylinder 4, and one of the guide rolls ll together with one of the guide rolls l2 serves to hold the cloth in contact with the perforated portion of the stationary cylinder 5.
For circulating the dye liquor through each cylinder there is provided a supply pipe 2i which leads into the cylinder through the wall of the vat and which is provided with discharge perforations 22 as shown in Fig. l; Any suitable pump mechanism is employed for withdrawing dye liquor from the vat and forcing it under pressure into the supply pipe 2,! for each cylinder thereby causing the dye liquid to be forced through the cylinder'and not through the perforations 9 thereof. In the construction illus trated in Figs. 1 and 2 there is a, pump 23 for each cylinder, the inlet of the pump communicating with the interior of the dye vat l and the discharge of the pump being connected to the pipe 21, so that the circulation of the dye liquid through each cylinder is caused by an individual pump. It would be within the invention however to employ a single pump which would serve to circulate the dye liquor through all of the stationary cylinders.
In order to provide for feeding the cloth over the perforated portions of the stationary cylinders with a gentle touch and without subjecting the cloth to harmful tension, I have provided the following means The feed rolls I3, M and i5 are all rotated at the same speed, that is, with the same number of revolutions per minute. The feed rolls however are made of different sizes, the first feed roll i3 having the largest diameter, the second feed roll M having a diameter slightly less than the feed roll l3 and the feed roll 15 having a diameter slightly less than that of the feed roll [4. This variation in the diameter of the feed rolls is illustrated diagrammatically in Fig. 7 wherein the largest circle may represent the size of the feed roll l3, the intermediate circle may represent the size of the feed roll [4 and the smaller or inside circle may represent the size of the feed roll i5.
Since the feed rolls are all rotating at the same R. P. M. the larger feed roll I3 will have a greater surface speed than the smaller feed roll 14 and will feed the cloth forward to the cylinder 4 slightly faster than said smaller feed roll M will take the cloth from said cylinder and feed it forward to the next cylinder 5. Hence slight slackness will develop in the length of the cloth between the feed rolls I3 and M which is passing around the cylinder 4. Such slaclmess will gradually increase until the feed roll I3 is ineffective for feeding the cloth forward, and the slackness will remain until the feed roll M has fed the cloth forwardly from the cylinder 4 sufficiently to take up such slackness. When the slack has been removed from the cloth and the latter again becomes taut the feed roll I3 will again be operative to feed the cloth forward and such feeding will continue until sufiicient slack has again developed in the portion of the cloth between the feed rolls l3 and 14 to render the feed roll l3 again inoperative for feeding the cloth. The continued operation of the feed roll [4 will then gradually take up the slack and again render the feed roll !3 operative to feed the cloth. By reason of this action the cloth which is passing around the cylinder 4 will be subjected to a constant rhythm similar to a continuous breathing motion and the cloth will be led around and in contact with the perforated portion of the cylinder l with a gentle touch and will not be subjected to any harmful tension.
Because of the difference in the diameter of the feed rolls M and I5 the same action will occur with reference to the cloth which is delivered from the feed roll [4 to the stationary cylinder 5 and hence the cloth will be led around the perforated portion of the cylinder 5 with the desired gentle touch and without being subjected to any harmful tension. A factor in securing such gentle touch contact of the cloth with the perforated portion of each stationary cylinder is the fact that the dye liquid is being forced outwardly against the cloth through the perforations of the cylinder, thus tending to force the cloth away from the cylinder andassisting to eliminate any friction contact of the cloth on the cylinder as said cloth moves forward.
It is to be noted that only the bottom portion of each stationary cylinder is perforated and that l in passing over each cylinder the cloth covers the entire portion of the cylindrical surface which is perforated. Hence, all the liquid that is discharged from any stationary cylinder passes through apertures therein that are covered by the cloth and, therefore, is forced through the cloth.
The delivery roll 26 which delivers the cloth from the perforated cylinder 6 is drivenby a friction drive so that said delivery roll will apply to the cloth the requisite tension to hold the ferent compartments 35.
cloth against the cylinder 6 with 'the desired gentle touch.
' Any suitable means for driving the feed rolls I3, I4, and I5 at the same speed and for operating the delivery roll may be employed without departing from the invention. As herein shown the shaft 24 for each feed roll is provided with a sprocket wheel 25 and said sprocket wheels are connected to operate in unison by means of a sprocket chain 26. One of the sprocket wheels may be driven by any suitable source of power as indicated by the driving sprocket 21. The delivery roll 29 is driven through the medium of a friction clutch device 28 from a drive shaft 29 that is mounted in suitable bearings 30. The drive shaft 29 has a sprocket 3| thereon connected by a sprocket chain 32 to a sprocket wheel on the shaft for one of the feed rolls as best seen in Fig. 2.
In Figs. 5 and 6 I have shown a construction 6 the vat containing the washing liquid is indicatin which my invention may be used in connection with a device for washing cloth rather than dyeing it. In the construction shown in Figs. 5 and 6 the vat containing the washing liquid is indicated at 33 and it is divided by partitions 34 into dif- Each compartment 35 contains a stationary perforated cylinder and the cloth to be washed is fed through the various compartments one after the other by means of the feed rolls I311, Ma and 15a in the manner described above, there being a pair of guide rolls I002, Ha or l2a between each two adjacent perforated cylinders.
So far as the feeding of the cloth through the various compartments 35 and around the various perforated cylinders 3a, 4a, 5a and Ba. is concerned, the operation of the device in Fig. 5 is the same as that of Fig. 1. In the device of Figs. 5 and 6 however the inlet 36 of the pump 23a for the cylinder 3a is connected to the compartment in which the cylinder 4a is located, While the in- -let 3'! for the pump delivering liquid to the cylinder 4a is connected to the next succeeding compartment 35 containing the perforated cylinder 51:. Similarly the pump for delivering the washing liquid to the cylinder Ed has its inlet 33 connected to the compartment containing the cylinder 6a, while the pump delivering the washing liquid to the cylinder has its inlet connected to a fresh water supply pipe 39.
The vat 33 is provided with an overflow or discharge pipe connection 4%) at the end. thereof into which the cloth to be washed is fed. With this arrangement the fresh water will be delivered to the compartment 35 at the delivery end of the tank and water from said compartment is delivered to the cylinder in the next preceding compartment and so on through the various com partments. The washing water thus circulates through the various compartments successively in a direction counter to that in which the cloth is moving.
In order to provide for effectively treating cloth of different widths, each cylinder 3, 4, 5 or 6 is provided with two discs 4!, 42 situated interiorly thereof and of a diameter to fit the interior diameter of the cylinder. with an opening 48 through which the corresponding pipe 2| passes.
Means are provided for adjusting the discs 4!, 42 toward and from each other, thereby spacing the two discs in each cylinder a distance apart equal to the width of the cloth to be treated.
For this purpose there is provided'a shaft 43 extending axially through each cylinder, and each shaft has at one end a right-hand screwthreaded portion 45 that engages the hub 41 of the disc 42, and at the other end a left-hand screw-threaded portion 44 that has screwthreaded engagement with the hub 41 of the disc 4i.
Ihe shaft 43 extends through one of the walls 8 of the vat and is provided with a, hand wheel 46 or other device by which it may be turned. By turning the shaft 43 in one direction the discs 4!, 42 will be moved toward each other and by turning said shaft in the opposite direction said discs will be moved away from each other.
In treating a Web of cloth the discs 4|, 42 of each cylinder will be adjusted relative to each other so that they are spaced apart a distance corresponding to the Width of the cloth.
Ihe perforations 22 in the pipe 2| for each cylinder are confined within a zone having a length no longer than the narrowest web of cloth to be treated so that under all conditions the liquid forced through the pipes 2| will be delivered between the discs 4|, 42.
