Description

Device for the production of a relaxed cloth article des. Patent 577,942 is an apparatus for making a relaxed fabric and other tissues in which the tissue to be treated passes through the opening of steam boxes for steaming, then over a heating device for shrinking (shrinking), then via a spray device and finally via an upwardly directed conveyor belt and an ironing press is guided. The first steam box can optionally be replaced by a damping cylinder.

In practice it has now been found to be necessary through the finishing and, in particular, that has come into the goods through pressing and decating To solve the hardness completely before the cramp treatment and for this purpose by steaming and soak the fabric web to be treated smoothly. According to the invention this is done with the aid of a follower covering the damping cylinder and one on reached the damping cylinder subsequent conveyor belt. The ones with a certain severity still. provided fabric web is thereby between the follower and the felt covering steamed, moistened and smoothed, which at the same time loosens the hardness. Afterwards, the so-soaked goods, decated without pressure, as it were, become tension-free Carried on a slatted table, where the retained moisture has time to soak in takes place in the tissue. The object of the invention is in the drawing in a exemplary arrangement shown. . Fig. I is a vertical longitudinal section, Fig. 2 is a front view, Fig. 3 is a different fabric guide in front of the steaming box.

If the W .If a spreader i in the direction of arrow I to a guide roll 2 a heated damping cylinder or drum 3 supply performed by the drive R, 2g ,. 30 receives its rotary motion. This is perforated on the outer circumference and wrapped with a felt covering 4 and carries the steam inlet 5, .31 in one pin, the condensate outlet 6, 32 in the other pin. The felt covering 4 is applied by an applicator roller 7 with water or a wetting agent Box 8 moistened. The cylinder felt covering 4 is covered on the outside by a follower g, which is guided endlessly over guide rollers io. Due to the steam heat of the cylinder, the moisture brought into the felt covering 4 is converted into cool, wet saturated steam. At the same time, the goods T4 'are pressed onto the wet felt covering by the follower g and are thoroughly dampened and moistened in the process, the goods absorbing the moisture that they can grasp, depending on their severity. Furthermore, the goods are smoothed at the same time, whereby their hardness is broken. The goods are then lifted off the felt covering 4 by a chopping roller ii and placed in folds on a periodically moving, rising slat table 2, whereby the moisture finds time to absorb into the fabric and is carried without tension in the direction of arrow II. At the end of the lath table 12, the goods hang in a fold 13, are picked up by the conveyor roller 14 and guided by this via a steaming box 15 for steaming again, whereupon they slide downwards over the flat, inclined shrinking plate 16 without tension in the direction of arrow III and can shrink on this in length and width.

If the plate is heated with steam, this enters the individual heating elements 17 through line 18. A manometer 1g indicates the vapor pressure, a thermometer 2o the temperature of the shrink plate 16. At the end of the platter, the product is non-shrinkable and still hot. It is wetted by a controllable atomization 21, 22, 23. This consists, for example, of the container 21 filled with the net liquid, in which an applicator roller 22 transfers the atomizing liquid to the roller brush 23. A pump 27 feeds the wetting device 21, 22, 23 from container 28. The wetting liquid is absorbed by the hot goods, thereby cooling them and slightly moistening them, which is advantageous for the subsequent press to ensure that the goods are completely refined.

Then the goods are in a known manner in the direction of arrow IV to the table device 24, 25, 26 and then possibly receives a press.

So that the goods can be brought in and out smoothly on their way, a fold is formed at 13 in front of the roller 14 so that the goods sag. To In Fig. 3, the roller 14 can also be arranged over the leading edge 15 ′ of the steaming box 15 so that the goods also hang downwards before they run onto the steaming box. However, this arrangement does not form part of the subject matter of the invention.

When passing through the device according to the invention, the goods experience following treatment: a) Thorough steaming and dampening while at the same time Keeping the web of fabric smooth, the hardness being broken by the decatur and press and the goods are conveyed smoothly and softly; b) Drawing in the moisture into the web of fabric; c) steaming through again; d) tension-free shrinking; e) cooling and moistening by wetting.

The humidifier for cooling and wetting the web can also consist of a nozzle arrangement or similar humidification.

Only water or that with a chemical can be used as a wetting liquid Wetting agents are used, which further accelerates the penetration of moisture is achieved in the fabric web.

The inclination of the flat shrink plate is arranged so that the on it Goods to be shrunk W in the dry state are downward due to their own weight slips and no significant tensile stress can arise as a result.
