  • Patent number: 8756830
    Abstract: A media drying system removes a moistening liquid from a moistened medium, the moistening liquid having a moistening-liquid boiling point. A liquid reservoir contains a heating liquid. A liquid-heating system warms the heating liquid in the liquid reservoir to a temperature greater than the moistening-liquid boiling point. A media-transport system transports the moistened medium along a transport path which passes through the liquid reservoir. The moistened medium is submerged in the warmed heating liquid and heat is transferred from the warmed heating liquid to the moistening liquid. This vaporizes the moistening liquid and removing it from the moistened medium.

  • Publication number: 20140033560
    Abstract: A high efficiency steam box, particularly for the processing of fabrics. The box housing is subdivided into a plurality of steam chambers isolated from each other but communicating with a perforated steam tube which extends throughout the housing. Steam is delivered to the center portions of the steam tube and flows toward the ends. Valve pistons are movably positioned in the opposite end portions of the steam tube to confine the steam. The valve pistons are axially adjustable by a screw shaft extending through the steam tube and can be positioned to isolate outer chambers when processing narrow fabrics to prevent or minimize the discharge of steam from steam discharge slots extending beyond the edges of the fabric. Steam flow control can be integrated with positioning of the valve pistons to provide uniform steam flow per unit length of the discharge slots for optimum efficiency in processing and steam utilization.

  • Patent number: 8615899
    Abstract: Apparatus and method for the non-contact drying of a web of material. The apparatus includes air flotation nozzles for floating the web, and direct air impingement nozzles for enhanced drying of the web. The nozzle arrangement is particularly well-suited to float and dry light weight webs under moderate to high tension. Increased cushion pressure is created to support the web preferably with the same horsepower as conventional arrangements. The increased cushion pressure pad of the nozzle arrangement allows for good flotation with reduced velocities below about 11,500 FPM. Machine direction wrinkles are removed and the result is positive flotation with no marking on the web or ink build up on the air bars. The nozzle arrangement includes pairs of flotation nozzles directly opposing pairs of direct impingement nozzles. A perforated member can be positioned between flotation nozzles within a pair of flotation nozzles to control return air.

    Abstract: In known rack dryers, the drying effect is weaker in the outer area on the side of the air intake into the pipe chambers than in the other areas. Said weaker drying effect is caused by turbulence in this area, which leads to a drop in the static pressure. The aim of the invention is to provide a dryer which ensures even drying of the goods across the entire width, even in the problem areas. The rack dryer is equipped with conductive bodies (20, 26) which are located on the partition wall (5) and which streamline the current in the area of the air intake into the pipe chambers in such a way, that a predominantly even static pressure prevails throughout the entire pipe chamber.

  • Patent number: 6564473
    Abstract: A method and apparatus for impingement of fluid onto a moving surface. The apparatus includes an asymmetric slot nozzle having an opening formed between an upstream wall and a downstream wall. The nozzle is disposed generally adjacent the surface onto which the fluid is to be impinged forming an impingement distance between each of the walls of the nozzle and the surface. The impingement distance of the upstream wall is greater than the impingement distance of the downstream wall such that at least a portion of the fluid is delivered through the nozzle in a direction that is counter to the machine direction.

  • Patent number: 6484418
    Abstract: A method, system and apparatus is disclosed for drying a wet web quickly and efficiently on the surface of a steam heated drying cylinder in a continuous papermaking process. A steam-heated drying cylinder having an exterior surface is rotated under a drying hood adjacent the exterior surface of the drying cylinder. The hood comprises a drying zone of heated air, with nozzles adapted to supply hot air streams into the drying zone. A wet web is adhered to the drying cylinder and rotated through the drying zone of the hood. Then, hot air streams are directed from the nozzles upon the wet web. A hot air stream is provided from a nozzle at a lead angle that deviates from perpendicular between about 3 and about 30 degrees, in a lead direction towards the downstream end of the web drying process.

  • Patent number: 6382100
    Abstract: A roller assembly positioned downstream of a printing station in a web-fed rotary printing press for pneumatically guiding a web of paper after it has been printed upon, without the risk of smearing the printings. The assembly includes a roller in the form of a hollow cylinder defining a plenum chamber therein and having formed in its surface a multiplicity of air outlet openings in communication with the plenum chamber. Air supplied under pressure to the chamber is therefore expelled from the air outlet openings in order to avoid contact with the roller the web traveling over the rollera baffle encloses at least part of the circumferential part of the roller surface for confining the air being expelled from said at least part of the other circumferential part of the roller surface and for redirecting the confined air into a pair of spaces, spaced, between the web and the roller.

  • Patent number: 6298577
    Abstract: A device for enhancing removal of liquid from fabric utilizing mechanical and aerodynamic techniques. A base plate contains one or more apertures to which a vacuum is applied for extracting water from the fabric. The total cross-sectional area of the apertures is selected to be that which will increase, and preferably maximize, the extraction power for the vacuum motor with which said base plate is to be utilized. The number and shape of the apertures is selected to reduce the ratio of the total distance along all the perimeters of said apertures to the total cross-sectional area of said apertures in order to reduce boundary layer drag. The cross-sectional area of each of said apertures is selected to be large enough to permit solid contaminants that can be expected to be in the liquid to pass through said apertures without clogging said apertures. Barriers are attached to the bottom of the base plate to force any liquid in the fabric toward the apertures as the base plate is moved across the fabric.

  • Patent number: 6230422
    Abstract: A method and apparatus achieve a more sustainable lift of a wet or heavy pulp web from a pulp machine to the topmost drying level of a pulp drying, allowing the speed of production to be increased and runnability problems to be minimized. The pulp web is lifted from the last press of the pulp machine to the topmost of the drying levels of the pulp dryer by supporting the web on a support wire. The pulp may be passed through the topmost drying level, and one or two other levels, also supported by a support wire, but in subsequent levels the pulp web is preferably supported only by an air cushion. In each level drying gas is blown toward the pulp web (preferably from both above and below the web) to effect drying, and the web passes around turning rolls between each drying level to enter the next, lower, drying level. The support wire may be of metal or plastic, and has a texture significantly coarser than the texture of wires commonly used in pulp machines.
