  • Patent number: 5570594
    Abstract: A permeable drum for wet or dry treatment of textile material, paper or such permeable materials of a certain width comprises narrow sheet metal strips or narrow webs. The sheet metal strips extend in an axially parallel direction. Connector members between the sheet metal strips are aligned in the peripheral direction. The connector members, also serving as spacers, are of a one-piece design and connect to adjacent sheet metal strips. Secure connection of the spacers to the sheet metal strips is effected by screws. Radially inward beneath the inner edges of the strips is a sheet metal jacket, provided with apertures, having its axis arranged in parallel to a longitudinal axis of the permeable drum. This additional sheet metal jacket causes a certain dynamic pressure of the air flowing through the permeable drum, so that the treatment result is rendered more uniform. Furthermore, the precision of rotation of the permeable drum construction is increased.

Pulp which has been washed on the upper counter-current washer may be removed and subjected to a chemical action, such as a bleaching action, and then reapplied to a horizontal return run section of the wire by a headbox to form a pulp mat on the inside surface of the wire. This pulp mat is subject to further countercurrent washing by the application of wash water to an upper surface of the mat and by draining of the wash water through the wire by suction boxes. This wash water may advantageously be applied as the wash water to the last stage of the counter-current washer along the upper run.

    Abstract: Multiphase washing of pulp is accomplished on a fully pressurized drum filter by employing compaction baffles to increase the consistency of the pulp mat and by providing a separate pump for each wash zone so that there is no pressure difference between the wash zones and, thus, no need for any mat contacting mechanical seal. This avoids mat disruptions and machine clogging often caused by pulp pile-up at such seals.

The elongated tube is continuously fed lengthwise into a series of liquid baths which include a wetting agent, scouring and washing constituents and rinses and any finish is to be applied to the fabric. The fabric tube is caused to advance into and through the bath in a substantially tensionless state by pushing the fabric into the flow of liquid and through the bath to avoid applying substantial tension. From the washing and rinsing baths, the saturated fabric is flattened, again without application of substantial tension, and is fed through a two-stage dryer. In the initial stage, the fabric is air-dried to a moisture content of substantially less than 40%. Before introducing the fabric into the second stage of the dryer, the moisture content is raised, for example in a steam atmosphere, to substantially 40%.

  • Patent number: 4849261
    Abstract: A saturator of the type comprising a chamber situated between a chamber defining element and a mandrel, in which a web is moved between the chamber defining element and the mandrel to impregnate the web with a saturant contained in the chamber includes at least one saturant delivery port which extends across substantially the entire width of saturation zone which extends only partially across the web if the chamber defines a plurality of saturating zones. In this way, uniformity of saturation across the chamber is improved.

  • Patent number: 4829792
    Abstract: A double drum batch washing machine comprises an inner cylinder, an outer cylinder, an inner helical transfer screw with the inner cylinder and an outer helical transfer screw within the space between the inner and outer cylinders. The inner helical transfer screw has a pitch in one direction and the outer helical transfer screw has a pitch in the other direction so that the compartments formed by the transfer screws within the inner cylinder and the space between the inner and outer cylinders define areas of overlap on the surface of the inner cylinder. The areas of overlap have holes formed therein so that fluid interchange is established between each outer compartment and only the corresponding overlapping inner compartment. Laundry is placed in the inner compartments and wash water is placed in the outer compartments such that it communicates with the inner compartments and the laundry contained therein. Laundry is washed by oscillating the washing machine through a predetermined angular arc.

  • Patent number: 4827741
    Abstract: An air-tight vat under pressure completely encloses a rotatable drum. The vat is constructed so that it may be completely submerged in liquid. The vat has a liquid filled take-off chamber. The pulp is fed to the vat through a pulp inlet. The pulp is formed and compacted to form a pulp mat. Directly following the forming and compacting of the pulp is a washing zone for washing the pulp mat. After washing the pulp mat is again compacted. The pulp mat is removed from the drum at a removal point located in the liquid filled take-off chamber, thus providing a pulp suspension in the take-off chamber. The suspension is removed from the vat through a pulp outlet extending from the liquid filled take-off chamber.

  • Patent number: 4811574
    Abstract: A permeable drum for the wet or dry treatment of textile material, paper, or other permeable materials of a certain width has a screen-like cover supported solely on narrow sheet metal strips or narrow webs. The sheet metal strips extend axially parallel, their extension in width being oriented in the radial direction. The webs are oriented in the peripheral direction and form part of the connecting elements between the sheet metal strips, these connecting elements also carrying the screen-type cover. The connecting elements, also serving as spacers, are formed of one piece and connect two neighboring sheet metal strips. Connection of the spacers with the sheet metal strips is achieved by screws, bolts or the like, of which suitably two in superposition extend longitudinally through bores in the connecting elements.

  • Patent number: 4745935
    Abstract: In apparatus for treating a product in a liquid bath having two different temperature zones separated by a slotted wall and equipped with at least two continuous conveyor belts arranged to transport the product while captured between the belts through one zone, a slot in the wall and the other zone, a plurality of submerged nozzles are positioned with their orifices directed to eject pressurized fluid streams that contact the belts while passing through the slot. The nozzles promote the flow of liquid from one zone to the other and effect scrubbing of the belts. Baffles at the wall slot and parallel to the belts enhance the operational benefits of the nozzles.

    Abstract: A saturator of the type comprising a chamber situated between a chamber defining element and a mandrel, in which a web is moved between the chamber defining element and the mandrel to impregnate the web with a saturant contained in the chamber includes a stencil having at least one impermeable region shaped to cover less than the entire web. The stencil is passed through the chamber at the same speed as the web with the stencil juxtaposed against the web such that portions of the web aligned with the at least one impermeable region are not impregnated with the saturant, while other exposed portions of the web are impregnated with the saturant.

  • Patent number: 4611476
    Abstract: In an apparatus for the continuous washing of a length of textile material, the textile material runs over several guide rolls, at least one of which is arranged below the liquid level in the washing vessel. In order to be able to skip a washing device, in a continuous plant, so that the length of material does not enter the liquid and causes contamination therein, for example, the invention provides to mount the guide element to be movable out of the vessel. Therefore, the length of material still passes around all of the guide rolls of the washing device, but in this case outside of the liquid charged into the vessel.
