Abstract: A method of cooling a material web includes, after drying a material web, moving the material web in a given direction on a meander-shaped web path over a cooling cylinder and at least one other cylinder disposed at a location selected from a group thereof consisting of a location upline and a location downline from the cooling cylinder, as viewed in the given direction of the web path, providing for the moving of the material web to be with at least partial looping thereof over the cooling cylinder and the other cylinder, and arranging the cylinders with respect to one another so as to exclude contact pressure with one another that is in effect between two respective ones of the cylinders; a device for performing the method.

Abstract: Process and apparatus for drying a material web. The process includes guiding the material web to at least one heated area having a jacket surface of a cylinder having a diameter of between about 4-10 meters, setting the material web, having a dry content of between about 45-55%, onto the at least one heated area, maintaining the material web in uninterrupted contact with the at least one heated area at least until the material web achieves a firmness sufficient for detaching the material web from the heated area, and detaching the material web from the at least one heated area with a dry content of between about 55%-65%.

Abstract: Flux management systems and methods are provided for filtering vaporized flux from the gas of a reflow soldering oven. A flux management system includes a cooling chamber having a cooling medium through which the gas passes. The vaporized flux condenses on the surfaces of the cooling chamber and drips into a collection pan, thereby preventing it from dripping onto circuit boards passing through the oven. The flux management system may further include a self-cleaning feature that includes a compressed gas, which is allowed to enter the cooling chamber through a solenoid valve. The compressed gas may then be directed through a heater, which increases the temperature of the cooling chamber, thereby causing a decrease in viscosity of the flux, which allows it to flow freely into a drain tube. The flux may then be transported by gravity into a collection container.

Abstract: The inverted bonnet hair dryer is comprised of a bowl with a closed end and an open end. The bowl is pivotally supported on a stand and is rotatable to a position with its open end facing upward. The bowl is comprised of a hemispherical concave inner wall which is generally spaced from an outer wall. The perimeter of the inner wall is connected to the outer wall to define a space between the walls. A hollow tube is attached to the outer wall. An aperture at an outer end of the tube is in communication with the space within the bowl. The aperture is adapted to receive the head of a conventional hand-held electric blow dryer. When the open end is facing upward, the bowl is adapted to be positioned under the head of a person. The head is inverted to hang the hair under the head. The inner wall of the bowl is adapted to evenly support the hair. When the blow dryer is activated, hot air is forced into the space between the walls and released through holes on the inner wall to dry the hair.

Abstract: The invention relates to a method of drying a fiber web and an arrangement in a fiber web drying apparatus, the fiber web being dried between two tight bands that move in parallel in the same direction and turn around turning rolls. The first band is heated and the second band is cooled. The fiber web is guided through a drying zone, defined by the bands, with at least one felt or wire, so that the fiber web comes into contact with the surface of the first, heated band and the felt or wire is between the fiber web and the second, cooled band. The position of the edge of the band is measured by means of a sliding block which is brought into contact with the edge of the band, the material of the sliding block being substantially harder than that of the band.

Abstract: An offset printing apparatus has a fluid-cooled nip roll which, in use, is placed in intimate contact with a hot, rapidly moving, endless printed and dried paper web so as to improve the cooling efficiency of the first downstream chill roll, permit the use of fewer chill rolls, and avoid condensate streaking. The apparatus takes the form of a nip roll specially designed to press the web into intimate contact with the first downstream chill roll while avoiding damage to the web, nip roll, or chill roll, and while avoiding ink picking by the web surface contacted by the nip roll. Employing the nip roll in the system also permits the use of a substantially shorter dryer and fewer chill rolls as compared to a conventional system operating at the same web speed. The coolant circuit for the nip roll includes a warmup loop which temporarily circulates warm fluid through the nip roll when the system is first taken off-line, thereby preventing condensate formation or frost formation on the nip roll.

Abstract: Web cooling device where liquid is applied to both sides of a hot web to enhance cooling via evaporation of the liquid from the web.

Abstract: An apparatus for transferring heat from a web includes a chill roll having a cylindrical outer side surface. The web moves along a path which extends part way around the chill roll. A nozzle extends between opposite edge portions of the web and extends circumferentially around a portion of the cylindrical outer side surface of the chill roll. A central portion of the nozzle directs a flow of air against a central portion of the web upstream of a location where the web normally engages the chill roll to deflect the central portion of the web into engagement with the chill roll. Opposite side portions of the nozzle extend away from the central portion of the nozzle and extend downstream from the location where the central portion of the web is deflected toward the chill roll. This results in a smoothing action which extends across the web and downstream along the web from the central portion of the web.

Abstract: A method and device in the drying of paper, especially of fine paper or newsprint is disclosed. A paper web to be dried is passed over a mantle face of a large-diameter flow-through cylinder. On the flow-through cylinder, a set of drying-gas jets is applied to the free outer face of the web through a nozzle arrangement. Water is evaporated outward from the outer part of the web by means of the set of drying-gas jets. The water vapor thus evaporated is removed through spaces in the blowing-on hood. By means of the set of drying-gas jets, the interior of the web to be dried is also heated. The mantle face of the flow-through cylinder is cooled by means of a medium flow. Water that has been vaporized out of the web and that has been condensed onto the cooled faces is sucked by means of negative pressure present in the interior of the flow-through cylinder.
