[56] References Cited 3 Claims, 3 Drawing Figures UNITED STATES PATENTS 1,192,903 8 /1916 lefierson 68 /14 0 X DEVICE FOR TREATING DONG FLAT TEXTILE MATERIALS This invention relates to a device for treating flat textile structures, especially webs of fabric, in a rotating drum provided with apertures for the inlet and outlet of a liquid or gaseous treatment medium.
Devices of this type have long been known for the washing and chemical cleaning of garments or laundry. For some time drum machines of this type' have also been used for treating long webs of material in the finishing of textiles. Considerable problems arise however with this last-mentioned application. Irrespective of how the long webs of fabric are laid in the drum, during the course of treatment the web runs together into a cord and becomes twisted and snarled. This leads to irregular treatment of the fabric web, to the formation of folds, and especially to time-consuming and tedious subsequent operations to remove the twists and snarls.
Attempts have been made to prevent this twisting and snarling of the fabric web by limiting the freedom of movement of the material within the drum. For this purpose the flat textile structures have'been packed into coarse-meshedbags, or the cross-section of the drum has been divided by horizontal inserts into a number of chambers. These solutions to the problem are however unsatisfactory, since they greatly affect the uniform changing of the position of the material in the drum, especially the aimed-for free fall of the broadly laid-out web, which is desired in the treatment of the material.
The invention is therefore based on the problem of constructing a device of the type described, which firstly prevents the undesired twisting and snarling of the material and secondly achieves uniform displacement (change of position) of the material in the drum.
According to the invention this problem is solved by the combination of the following features:
a. The length of the drum is at least as great as its diameter;
b. The drum has on its inside at least one radially disposed rib, whose height is 20-50 percent of the drum diameter;
0. The holes for entry of the treatment medium are uniformly distributed over the whole length of the drum.
The tests on which the invention is based have shown that the choice of an adequate length for the drum is the first condition for avoiding the twisting and snarling of a web of fabric treated in the drum. A drum length corresponding to the drum diameter must be considered as a lower limit; in general it is more desirable if the ratio of drum length to drum diameter is greater than about 1.25. In any case the length of the drum must be at least equal to the maximum width of the web of fabric.
The drum can be divided along its length by adjustable intermediate walls to permit adaptation to any particular width of fabric.
An important combinational feature of the device provided by the invention is also the relatively high radial rib which has a particular function in guiding the web. During the rotary movement of the drum this rib provides the necessary shifting of the fabric in the drum, while its height ensures a good positioning of the web during its largely free fall in thedrum.
An important feature for the combination provided by the invention has also been found to lie I in the uniform distribution over the entire length of the drum of the holes for entry of the treatment medium. If the medium is instead supplied irregularly, a force is applied to one side of the web only, and tests confirm that this considerably favors the undesired twisting and snarling of the web of fabric.
The simultaneous application of the features of the invention as explained above provides ideal treatment of the web inside the drum; the undisturbed free fall of the broadly laid web provides excellent treatment quality; through avoidance of twisting and snarling phenomena the quality of the fabric is greatly improved, and subsequent time-consuming work is avoided.
These and further features of the invention appear from the following description of an embodiment shown in the drawings. In these:
FIG. 1 is a longitudinal section through a device in accordance with the invention;
FIG. 2 is a cross-section during movement of the drum; I
FIG. 3 is a cross-section during the rest position.
Inside the fixed drum housing 1 is a perforated drum 3 adapted to receive a long web of fabric 2, and which can be rotated by a-reversible drive, not shown. The length of the drum is considerably greater than its diameter.
On its inside the drum 3 has a rib 4, disposed generally radially and with a height of 20-50 percent of the drum diameter.
On opposite sides of the rib 4 there are disposed on the internal periphery of drum 3 two spray pipes 5,6 which rotate with the drum, and over their entire length have uniformly distributed holes for emergence of the liquid treatment medium. The two spray pipes 5,6 are fed from a conduit 7 which passes through the hollow shaft of the drum and is connected to a device 8 wherein the treatment medium 10 withdrawn from the drum housing 1 via a conduit 9 is prepared afresh. The drum 3 can be divided along its length by transversely extending longitudinally adjustable intermediate walls 12 to permit adaptation of the width of the drum to any particular width of fabric 2.
The drum housing 1 and the casing of the drum 3 are each provided with a slot or aperture extending along each members entire length, and covers are provided to close the slots or apertures when the device is in use. The slots and covers, which are not shown, are constructed in known manner and details thereof are not pertinent to the novelty of this invention.
The mode of operation of the device in FIGS. 1-3 is as follows:
Through the apertures, not shown, in the drum housing 1 and in the casing of drum 3, the web of fabric 2 to be treated is fed flat into the drum. The drum housing 1 is then filled fully or in part with the liquid treatment medium, which is made to circulate by a pump, not shown. The liquid treatment medium, sprayed through the pipes 5,6 in the direction of the arrows 11, comes into intensive contact with the fabric web 2, then passes outwardly through the perforated casing of drum 3, and is withdrawn through the conduit 9.
During this treatment the drum preferably undergoes a reversing movement, with pauses between the separate movements. The rotary movement between two successive reversals covers an angle between 180 and 360. If an angle of about 360 is selected, the rib 4 and the two spray pipes 5 and 6 preferably lie in the upper area of the drum 3 when this is in its rest position (see FIG. 3). As shown particularly in FIG. 2, during the rotary movement of drum 3 the rib 4 has the effect of guiding and stabilizing the web of fabric 2 during its free fall.
The device provided by the invention is obviously also suitable for the treatment of flat textile structures by gaseous treatment media. In this case the fixed housing surrounding the perforated drum is preferably provided with two slots extending over the entire length of the drum, one intended for the entry and the other for the exit of the gaseous treatment medium.
What we claim is:
l. A device for treating flat textile structures, especially webs of fabric, in a rotating drum provided with apertures for the inlet and outlet of a liquid or gaseous treatment medium, the combination comprising:
