Abiohtvorriohtung for Druokdämpfor

The invention relates to a Druok steamer for overdruok-Sattdaupfbohandlung continuously durohlaufendor Toxtilbahnen. When known Druokdäinpfern consist of inlet and outlet devices from dioht rollers, which are pressed against the textile web on both sides Dieso Dioht * must roll both at their ends and over their entire length be abodiohtet against the base edge of the Därapferwandung, voffor wan face plates and diaphragm lips resting on the roll shell. These Diohtoittel are due to the temperature influence, the pressure » druok and the friction is so stressed that it only takes time are brewable «They also have a tifcerdruok from höohotens an atmosphere, so are not suitable for a higher pressure * net. To fix synthetic fibers, however, a saturated steam temperature of more than 120 ° Celsius is necessary, which means a pressure of more than alo 1.0 atm. Usually a vapor pressure of 2 atmospheres or more is required necessary, . "

Besides the Diohtv.'dlzensystem is continuously working for sealing Druokdärapfer known the end of endless followers who in general areas of the sin * and auaaaaaaen of the sole seats with the one in between lying Co: ctilbaha angoogle oind. Here is a draifaoho Ab · » seal necessary, namely one room between, the! textile web and the two Followers and twice between these and the diagonal edges of the steam, foi wall. In addition, two V.'ulzen * * paure. This Diohtaysten therefore consists of many components, what about the susceptibility to disturbances is relatively high

Bed a third Abdiohtsystem is the textile ground-au sintering and Off "trittsohlitz the damper av / isohon a bead Diohtlippo and a bofootigten on the opposite side air hose hindurohgeführt" This seal has the llaohteil that they can withstand a little over "· druok and also the Exposure to temperature and friction is not used for a long time

The invention includes a new method of sealing the inlets and outlets Autostrittsohlitae of pressure dampers for a continuous saturated steam

treatment of wide .toxtil groynes at more than 120 Celsius · basw »about 2 atmospheres or more. Bio Diohtvorriohtung according to the invention is rollerless and consists of two or more pairs of hollow, adjustable by a pressure means to a selectable pressure, attached to the sole seat edge of the damper edge, made of materials that have as little friction as possible to the textile web and against temperatures above 120 Celsius as well are resistant to chemicals contained in the textile web, such as fluoropolyasrisate. The spaces between two pairs of diohtlips on either side of the textile web represent pressure chambers, the hinaiohtlioh of the druoke and the temperature on j.iittolv / arto between the interior of the damper and dor outside Umtfobung ainatollbar oind, tronn nan si © with appropriate precautions »

In this way one can work with a much lower pressure dor Dioht * lippanpaare on the Durohlaufanda textile web and therefore with much less friction ala boi dan well-known Abdiohtsyatome ^.
