. The briefly measured times in the finishing τοη textiles nowadays do not allow goods to rest in damp rooms for several days or hours, thereby giving them the opportunity to absorb the missing moisture.

The increased production in the equipment is very often at the expense of the material, since, especially with woolen goods, the goods are "chased" ¹ * from one machine to another and have no opportunity to "rest".

Especially after steam and heat treatments, the Risk of tissue drying out.

The fabric webs which run out for the table under these conditions have, due to the various processes during the Drying, pressing, decatizing and shrinking, caused by hot air treatment, heat exposure, steam flow and Duration of exposure, a relatively high intrinsic temperature, which is in the order of 50 ° to 80 ° G.

When starting such a hot product there are considerable disadvantages, which have an effect in particular in Idegefalten and thus adversely affect the failure of the tissue.

Idegfolds arise especially when the goods are in when it is hot, it lies in the stack for a long time and is through the dead weight of the fabric layers, cracks and kinks are generated in the weft direction. For this reason one is already there

passed over, the expiring web of fabric with a cooling roller to conduct perforated surface. This Eühlwalze is in the take-off arm of the goods outlet mounted and "has a connection to a suction fan.

• It has been shown, however, that in the case of economic expiry speeds of the fabric across the chill roll actual time for cooling is too short, and that with this Working speed in no way can one speak of sufficient cooling of the material web.

If you consider that the fabric web is placed on a 220 to 300 mm chill roll with approx. 90 degree offset and therefore only one cooling section for cooling from 173 to 235 mm is available, then remains for the actual Cooling process at a working speed of 40 m / min, only one exposure time of the cooling air from 0.26 to 0.35 seconds. Even if the goods are supported at 180 °, only 0.52 to 0.7 seconds for actual cooling. These values show clearly that it is physically and also practically impossible is, the fabric web to room temperature within this period to cool off. Articles of goods of a certain quality are made with a view to a particularly desirable handle and appearance of the goods in full steam (without cooling on the decating cylinder) thus deducted and served with an even higher intrinsic temperature «., _. Cooling becomes even more problematic for these l? All because the fabric web leaking under steam brings with it steam plumes, which form an insulating layer over the goods and thereby make the thermal exchange during cooling considerably more difficult.

This is where the idea of innovation kicks in. The object of the innovation is to provide a device of the type mentioned create, which in a simple manner in connection with all, on the market, different in their dimensions and structure Finishing machines for wool and wool blend fabrics can be set up and used. According to the invention, this is achieved in that the device can be moved as a unit is, and that the transport device and with this connected blower box and suction box adjustable in height and at the angle of inclination with respect to the horizontal plane -; are pivotable within limits.

The carriers are another embodiment of the innovation

Another feature of the innovation are locks provided with which the transport device and the parts connected to it in a certain height and pivot position being held. ■ -; -

The transport device has an infinitely variable drive. The speed of the conveyor belt this The device can thereby der'Geschitzel the upstream Finishing machine can be adapted so that during transport

of the goods by the cooling and attracteth ζ one no stresses can occur and thereby shrinkage of the outgoing goods is made possible.

The web of fabric leaving the transport device is fed to a tray with two lieitbleehen, which in two end rotatably mounted rollers.

The goal direction according to the innovation can be used in conjunction with Drying machines, bowl presses, decating and shrinking machines and the like. Can be used.
