  • Patent number: 4136536
    Abstract: The present invention relates to sealing devices and is most expedient to be applied in dyeing-and-finishing processes involved in textile industry. The hermetic seal of the chamber for treatment of bandlike material at an excess pressure has a hollow shell accommodating a pair of driving rollers for traversing the material under treatment, and a sealing device which hermetically divides, along with the rollers, the shell interior into an excess pressure zone communicating with the chamber, and an atmospheric pressure zone communicating with the atmosphere. According to the invention, communication between the atmospheric-pressure zone and the atmosphere is established through the agency of a check valve provided in the shell and made as a flexible sleeve whose bore is adapted for the bandlike material under treatment to freely pass. Such a constructional arrangement provides for reliable hermetic sealing of the chamber for treating bandlike material under an excess pressure.

  • Patent number: 4136535
    Abstract: The apparatus comprehends a bath and a pad liquor supply charged thereinto, a guide means disposed within the bath for guiding the goods therethrough, and a steam jacket communicating with a steam source. The jacket lies in vertical disposition upwardly of the bath and has apertured top and bottom walls. A partition disposed within the jacket suspends downwardly from and connects to the jacket top wall in registry with the aperture thereof to define a primary passage through the partition which is open at its upper end to atmosphere and open at its lower end into the jacket, through which primary passage, the goods are passed before passage into the jacket. The jacket and partition cooperantly constrain the steam flow through the jacket in a first downward flow direction exteriorly of the partition in a heat transfer relationship therewith and in a second upward flow direction interiorly of the partition through the primary passage in a direction counter to the downward direction of movement of the goods.

  • Patent number: 4122611
    Abstract: An apparatus for the continuous thermal treatment of a product within an atmosphere made up of steam (saturated or superheated) of pure water or of a mixture of air and water vapor is disclosed. The product moves through an enclosed or confined space for its thermal treatment by the steam. The space is provided with entry and exit air-locks for the conveyance of the product into the space and for its removal. There are also means for guiding the product through the air-locks and the space. Additional means is provided to encourage thermal treatment and hence the space is provided with convection, radiation or conduction means to bring heat to the product. A first condensor receives vapor or humid air which is preferably extracted from the enclosed space via the adjacent air locks; it provides heat recovery of the purged vapor from the space. A second condensor is placed within the enclosed space and communicates with the high pressure discharge port of a compressor.

  • Patent number: 4122691
    Abstract: The present invention relates to equipment for treating a band-type material and can be used most successfully in the textile finishing and dyeing industry. The chamber for treating a band-type material under overpressure is formed by hermetically joined arched bottom, arched roof and side walls built into flanges so that the chamber has a crescent cross section and is provided with throats located near the flanges. This layout of the chamber reduces considerably its metal content and allows a number of chambers to be combined into a single installation to be used both for prolonged single-stage treatment and for multiple-stage treatment of the material.

  • Patent number: 4116627
    Abstract: For sealing a high pressure steamer air, pressurized to a level higher than the internal pressurized medium, in the drum body of the high pressure steamer is directed against the mutually contacting portions of rubber seal rolls. Initially, the pressurized air flows over the outside of a cylindrical duct extending between the opening for the passage of textile articles into the drum body of the steamer and the rubber seal rolls and the air serves to block the flow of the pressurized medium within the steamer through the opening. Sealing plates positioned between the interior of the steamer and the seal rolls, are forced into contact with the seal rolls by the pressurized air. Further the flow of pressurized air collides with the internal pressure medium of the steamer within the cylindrical duct preventing the exhaust of the internal pressure medium through the cylindrical duct.

  • Patent number: 4104893
    Abstract: An apparatus is described for continuously dyeing textile fabrics. The apparatus may be best described in terms of its operation as follows: The fabric is preheated in a chamber and then impregnated with a bath consisting of dyestuff dissolved in a solvent in another chamber. Then the fabric is treated in a developing chamber where the dyestuff is fixed thereon by evaporation of the solvent. The excess solvent is then eliminated from the fabric in a water vapor atmosphere. The treatment in the developing chamber is effected by passing the fabric continuously and alternately a plurality of times to and from a zone of saturated solvent vapor and a zone of superheated solvent vapor. The solvent in these two zones is substantially the same as the solvent in the bath.

  • Patent number: 4074544
    Abstract: The yarn entry and exit openings in a container for high pressure gaseous or liquid yarn heating medium are each sealed by means of a plunger mounted to slide in a cylinder extending from the opening. Each plunger is formed with a longitudinal groove of U-shaped cross-section on its surface. Therefore, to thread the yarn, it is only necessary to withdraw the plungers from their cylinders, place the yarn in the grooves and replace the plungers. Substantially to eliminate the escape of medium along the grooves, each may have a depth substantially equal to its width and amounting to between 0.1 mm and 0.5 mm, according to the yarn. However, to accommodate yarn with knots along its length or strechable yarn, this dimension may be increased and the pressure of any escaping medium reduced in a stepwise manner by recesses distributed along the plunger and intersecting the groove, into which recesses any escaping medium can expand.

    Abstract: A vacuum seal designed for the continuous movement therethrough of fibrous materials, such as carpet yarn, into a gaseous-plasma vacuum system while preserving a vacuum of about 1 Torr is described. The seal comprises a lower metal block with an elongated groove formed in the flat upper surface thereof and an upper metal block having an open bottom air chamber formed in its lower flat surface. In its assembled form, a flexible membrane is positioned between the formed, flat surfaces of the blocks. A seal is formed by pressurizing the air chamber in the upper block, thereby forcing the flexible membrane against the groove in the lower block and the upper side of the material passing therethrough, thus forcing the material to conform to the shape of the groove. Continuous variation in the degree of vacuum seal may be achieved by varying the pressure in the air chamber in the upper block.

  • Patent number: 3939576
    Abstract: A chamber seal is provided, which accommodates the entry into and exit from a processing chamber for a web of fabric. The seal serves to minimize the flow of gases into or out of the chamber, while at the same time minimizing frictional drag on the fabric, so that the fabric may be processed without excessive tension. The invention is especially useful in connection with processing of fabrics with liquid ammonia.The low pressure seal includes a guide member which engages and guides one surface of the fabric. The opposite surface of the fabric is contacted by a thin, flexible web of low friction material, such as Teflon-impregnated glass fiber cloth. The sealing web, which is highly flexible and conformable, is urged into contact with the fabric by means of a slightly compressed resilient tubular element, which is supported opposite the fabric guide. To advantage, the resilient element is not inflated, but provides the desired low pressure sealing force by reason of a slight deformation.
