摘要:
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. The selective communicating device is movable between a first configuration in which the discharge assembly is communicated with a first group of treatment zones and a second configuration in which the discharge assembly is communicated with a second different group of treatment zones. Accordingly, those exhaust products which are substantially pollutant-free can be routed along one path in which they are directly released to the atmosphere without conditioning while those exhaust products comprising pollutants can be routed along a different path to a reconditioning device which removes or neutralizes pollutants in the exhaust products before releasing the exhaust products to the atmosphere.

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. The intake conduit for the respective distribution housing which is laterally outward of the other distribution housing includes an extension portion passing through the laterally inward distribution housing, thereby making possible the space-saving compact arrangement in which both of the distribution housings are mounted on the floor on the same lateral side of the traveling web. According to one aspect of the invention, separate exhaust drying fluid regions are provided for separately guiding the exhaust drying fluid respectively above and below the dedicated one of the distribution housings.

A method and apparatus is provided for controlling the distribution of color on a web of textile material in a textile dyeing process. The apparatus includes a color sensor for sensing a selected color characteristic of the textile web, such as, for example, the distribution of color, at a sensing location downstream of a nip device of a textile padding machine. The nip device removes excess dye liquor from the textile web to dispose the textile web at an initial moisture content as it exits the textile padding machine. The amount of the dye liquor removal through the nip operation is controlled in response to the color characteristic sensed by the color sensor so that the textile web is disposed at an initial moisture content upon exiting the textile padding machine which facilitates a desired color distribution when the textile web is subsequently dried.

Method of controlling the continuous convective heat treatment of a textile fabric web, which includes continuously remotely monitoring the temperature of a web being transported over a path in a given direction, directing heated air toward the web, and measuring the amount of heat given off to the web, which is proportional to the temperature of the web, as a function of the difference between the temperature of the air impinging on the web and the temperature of the air reflected by the web.

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.

A traveling web transport assembly for transporting a web of textile material includes an endless chain having a plurality of web engaging members which engage one edge portion of the textile material web. The endless chain is formed with a plurality of cylindrical hub members each receiving a pin member therethrough. Each pin member is connected to an adjacent pin member by a pin link component and each hub member is connected to an adjacent hub member by a hub link component, the pin link components and the hub link components being arranged in alternating manner. A guide roller assembly mounted on each hub member includes an outer roller element rotatably supported on a ball bearing assembly. A lubrication conduit component includes a throughbore formed in a selected one of the hub and pin link components associated with each respective hub member and opening into the ball bearing assembly for introducing lubricant to the ball bearing assembly.

An apparatus and method for shrink treating both woven and knitted textile fabrics with essentially equal effectiveness provides a fabric-elevating intake device, a shrinking unit, a calendering device and a cuttling device in sequence for shrink treatment of woven fabrics in conventional fashion. Knitted fabrics bypass the fabric wetting device in the intake device and are wetted only lightly by a steaming cylinder provided at the intake side of the shrinking unit. An auxiliary fabric spreading device having driven rolls is also provided at the intake side of the shrinking unit to insure that knitted fabric is opened to a smooth full-width flat form. A small diameter drying cylinder is provided for partially drying knitted fabric without passage through the calendering device and a conveyor transports the knitted fabric in a relaxed condition to a winding mechanism. Woven fabrics are wetted by both the wetting device and the steaming cylinder and, after the shrinking unit, are calendered and cuttled in conventional fashion. Thus, problems of overwetting, overdrying and elongation of knitted fabrics are avoided, while retaining the capability for full conventional shrink processing of woven fabrics.

An infrared heating apparatus for drying a traveling textile fabric web or the like wherein radiators having a first gas-heated radiator surface and a second electrically-heated radiator surface are pivotably mounted for selective alternating movement of the radiator surfaces into and out of heating relationship to the traveling fabric web. The apparatus enables the selective cost-efficient use of differing energy sources.
