  • Patent number: 11225046
    Abstract: Embodiments of a system and a method for manufacturing a gypsum board can be used to produce a gypsum board having at least one perforated cover sheet via a cover sheet perforator system. The cover sheet perforator system can include a perforator roller is disposed downstream of a forming station along a machine direction, a roller support frame for rotatably supporting the perforator roller such that its rotational axis extends along the cross-machine direction, and a motor arranged with the perforator roller to rotate the perforator roller about the rotational axis. The drive motor can be adapted to rotate the perforator roller with a tangential speed substantially equal to the line speed to produce a series of perforation holes in an upwardly-facing cover sheet as the gypsum board moves past the perforator roller.

  • Patent number: 5055375
    Abstract: A method of forming an image which comprises subjecting an image-forming material comprised of a substrate and a photosensitive layer containing a dye and/or a pigment and a photopolymerizable compound and disposed on the substrate to an image-exposure, thereby to allow the exposure to cause a difference of adhesion between an exposed portion and non-exposed portion in the photosensitive layer, and transferring the image to an image receptor on the basis of the difference of adhesion; wherein the photosensitive layer of the exposed image-forming material and the image receptor are allowed to face each other and directed into the nip between two rollers consisting of an elastic roller and a metallic roller having a surface temperature of between 50.degree. C. and 150.degree. C.

  • Patent number: 4629867
    Abstract: There is disclosed a heated roll for the thermal treatment of formed products. It includes a driven hollow shaft and a hollow roll body of a circular-ring-shaped cross section and closed on all sides to accommodate a heat transfer medium. Power supply lines for heating elements as well as electric wires of temperature probes are led through the hollow shaft. In order to provide a heated roll to be used without problems both in the low-temperature range and in the high-temperature range up to about 600.degree. C. and to reach a uniform temperature profile over the total operation surface of the roll outer shell and a long service life of the heat transfer medium, without excessive temperature prevailing at the bearings of the driving shaft, and to provide for an easy repair, the hollow shaft is connected with the roll body by a hub. One or several saline compound(s) or (a) low-melting metal(s) or metal alloy(s) are contained in the interior of the hollow roll body.

    Abstract: The outer side surface of the drying cylinder (1) is delimited by a plurality of coaxial rims (2) having the same radius, arranged side by side and separated two by two by an axial space (7), and made of a good heat-conducting material. Each rim (2) is heated and cooled independently from the others by a heating member (8) and a cooling member (11) housed into a subrim (3) surrounding by the rim (2). The heating is provided for example by an electric resistance and the cooling by circulation of cold water, the control being provided by means of remote controlled relays (10). Each rim (2) is rotationally integral with a hub (5) wedged to a drive shaft (6). A comb (26) having teeth (27) engaged into the spaces (7) avoids the winding of material around the cylinder (1) which is in depression conditions in order to favor the heat exchanges by suction of the material against the cylinder (1). Applications to the equipment of dry ends and post dry ends of paper-, cardboard- or other web material machines.

    Abstract: The invention concerns variable contour rollers for use in calendering or pressing devices, printing presses and like applications. The rollers include an external element of cylindrical form, for example of cast iron, and in their interior a number of transverse elements which can be made to expand radially by heating. More or less substantial radial expansion provokes directly or indirectly a change in the profile of the exterior generally cylindrical working surface. The interior of the roller may be a shaft carrying heating elements and which is fixed or rotates with the external working surface.

  • Patent number: 4469549
    Abstract: Heat seal apparatus is disclosed which comprises a heater unit having a heater therein and a roller insertable in and removable from the heater unit. The roller, when in the heater unit, is in heat transfer relation with the heater so as to be heated to a predetermined temperature level. When the roller is removed for application on a package for heat sealing purposes, the heat stored in the roller performs the heat sealing function thus obviating the need for a heater located within the roller and for a power cord connected to the roller. The roller is a sealed, hollow tube filled with a suitable heat storage medium, such as paraffin or another low vapor pressure, high heat capacity compound, so as to ensure sufficient heat capacity in the roller for heat sealing purposes, to ensure uniform roller temperatures, and to require only a localized contact with the heater for substantially uniformly heating the roller.
