    Abstract: Conventional art has a structure consisting of a roll axis incorporating a structure of fine pores, and a roll unit provided around the outer circumference of a roll axis, wherein internal pressure of the roll axis is dispersed to the roll unit to make a fluid (gas-liquid) suction action, thus reducing the pressure loss and obtaining even distribution of the fluid (gas-liquid). As such, instead of a tubular roll axis, the structure of a roll axis is made fin-shaped or groove-shaped to maximize the action surface area that works on the inner pressure of the roll axis of the roll unit. However, other problems such as inefficiency of the fluid (gas-liquid) suction action and lack of mechanical strength of the roll axis remains.

The conductive roller has a metallic core, a conductive elastic layer formed on the outer surface of the core to which layer conductivity has been imparted by carbon black, and a surface-treated layer formed through impregnating a surface of the conductive elastic layer with a surface-treatment liquid, wherein the difference ?Hs (Hs1?Hs2) between micro-hardness Hs1 of a surface of the conductive roller and micro-hardness Hs2 of the conductive elastic layer after removal of the surface-treated layer, the hardness being determined by means of a micro-hardness tester, is 5% or less of the micro-hardness Hs2.

  • Patent number: 7914430
    Abstract: A roll is supported at the middle thereof, for a paper, board or finishing machine is composed of two sections, a so-called inner shell (54?) and an outer shell (52?), supported by one another in the middle area of the roll (50?). The nominal stiffness of the manufacturing material of the inner shell (54?) of the roll is substantially greater than the nominal stiffness of the manufacturing material of the outer shell (52?) of the roll.

  • Patent number: 7901751
    Abstract: The interchangeable sleeve comprises: a substantially cylindrical outer surface (105A); a layer of hardened resin (R); a substantially conical inner surface for connection to a conical central core of the roller. The inner surface is formed at least partially of at least one inner component (102) having greater rigidity than said hardened resin. The inner component is constrained to the sleeve by means of said hardened resin.

  • Publication number: 20100292061
    Abstract: in a cylinder and/or a roller and in a method for producing and/or for the maintenance of a cylinder and/or roller, a metal layer (8, 9, 10) is applied, at least in parts, to the outer surface (2) of the cylinder (1, 1?) and/or the roller (1?). The metal layer (8, 9, 10) has a ductile metallic matrix (4) having embedded hard material particles (5). Such a cylinder and/or roller can be used in a device (11) for controlling the wear and tear of a cylinder (1, 1?) and/or roller (1?), the surfaces (2?) of which are subjected to wear and tear. The method for producing the cylinder and/or roller, the cylinder and/or roller, and the device for controlling wear and tear, allow the maintenance, costs and labour of the cylinder and/or roller to be reduced.

  • Patent number: 7722516
    Abstract: A metal rolling pin system includes a metal rolling pin formed from a cylindrical metal body having a hollow core. A removable cylinder is disposed inside the core and is filled with a freezable material such as a cellulose gel material. The rolling pin may also have insulating material inside the core to prevent condensation. A silicone sleeve fits over the metal outside of the pin to keep the dough or pastry from sticking. The rolling pin system has more than one core to assure that there is always a frozen core to keep the pin and dough cold.
