Abstract: An apparatus for blowing air at a spread-out length of textile fabric being transported onward can be reduced in its dimensions and at the same time made more favorable from an energy standpoint during operation if the blow-out nozzles are embodied as injector nozzles. The injector nozzles can be flexibly adapted, in terms of their distribution in three dimensions, to the width of the length of fabric.

Abstract: The present invention provides a method and apparatus for monitoring the application of dye to a traveling web of textile material. The apparatus includes a color characteristic detecting assembly which is movable between an initial detecting position in which it detects a color characteristic of the textile material web shortly after the web has emerged from a dye liquor bath and a post-drying detecting position in which it detects a color characteristic of the textile material web after the web has been handled in a drying device. The post-drying detection of the textile material web enables the apparatus to detect an out-of-limits color characteristic situation which may not appear or be detectable until after the web has been subjected to the drying process. The color characteristic detecting assembly is connected to a control unit which controls the nip pressure of a pair of nip rollers which remove excess moisture from the textile material web.

Abstract: A method and apparatus are provided for handling the exhaust products produced during a treatment process in which treatment fluid is applied to a length of material. Several types of machines used in the textile industry and in the paper industry are operable to apply treatment fluid to a length of material in a treatment process during which exhaust products are created and some of the exhaust products comprise pollutants while other exhaust products are substantially pollutant-free. The present invention provides an exhaust products handling apparatus including an exhaust manifold connected to all the treatment zones of a treatment fluid applying machine, a discharge assembly connected to the exhaust manifold for drawing exhaust products away from the treatment zones, and a selective communicating device for selectively communicating the discharge assembly through the exhaust manifold, with a respective one of at least two different groups of treatment zones.

Abstract: A textile drying machine includes upper and lower distribution housings for applying streams of drying fluid to a traveling web of textile material from above and below the traveling web. The pair of distribution housings are each mounted to the floor on the same lateral side of the traveling web at a lateral spacing from one another and each provides a distribution opening which extends over the entire extent of the traveling web being treated. Each distribution housing includes an intake conduit for the intake of exhaust drying fluid which has been subjected to a heat exchange operation in which the heat content of the drying fluid is restored.

Abstract: A method and apparatus for converting heat energy of hot exhaust gases from a treatment chamber of a textile machine into electrical energy is provided. Hot gases exhausted from a treatment chamber of a textile machine of the type which uses heated gases such as, for example, heated air, are conducted to the compressor, combustion chamber and gas turbine assembly of an electric generator for driving of the electric generator. The exhaust gases can thereafter be conducted to a heat exchanger for releasing heat to be returned to the textile machine for use in its operation.

Abstract: A roll arrangement for the non-deforming treatment of moving web-type or strip-type products. The arrangement includes at least two rotatable rolls which are adjustable radially relative to each other. The arrangement is used, for example, for drying one or both surfaces of the product. The rolls are axially adjustable in opposite direction and each roll has slightly S-shaped or bottle-shaped contour over the entire length of the roll body, in such a way that the contours of two rolls arranged on both sides of a roll gap complement each other only in a certain relative axial position of these rolls. In other axial positions of the rolls, the roll gap becomes narrower either in the center or at the ends of the rolls, so that a uniform pressing action or other uniform non-deforming treatment of the product is possible over the entire width of the product independently of the bending of the rolls and/or deviations from the plane-parallelism of the surfaces of the product.

Abstract: The cylinder for guiding a web of textile material comprises at least one hollow space which is partly filled with a liquid heat carrier and can be evacuated. The pressure increase in the hollow space if the temperature is increased is to be limited to values below a multiple of calculated safety even though heat carriers with a steeply rising vapor pressure curve such as water are used. The solution consists in that only a quantity of heat carrier which can be evaporated completely in the volume of the hollow space already before a predetermined vapor pressure is reached, is contained in the hollow space.
