  • Patent number: 5766120
    Abstract: A calender roller includes a cylindrical base body. The base body has a thin circumferential wall, which is not self-supporting, and a support structure made of a thin-wall cellular material is disposed inside of the circumferential wall. At least a part of the walls which form the cells extend approximately in a radial direction, to provide a strong and light calender roller.
    Type: Grant

  • Patent number: 5759141
    Abstract: A calender roller has a cylindrical base body and a covering made of a flexible plastic material. The covering has an inside diameter that is greater than an outside diameter of the base body to define an intermediate annular space therebetween. A support structure is disposed in the intermediate space to transmit load forces from the covering to the base body.

  • Patent number: 4498383
    Abstract: A system of rolls for use in a calender, printer or rolling mill has a pair of rolls at least one of which has a hollow cylindrical shell with an elastically deformable line. The shell surrounds a stationary carrier and confines a row of electromagnetic or hydraulic force applying devices which can be adjusted individually to thereby regulate the pressure between the two rolls and hence the temperature at the exterior of the liner. Such temperature is monitored by one or more sensors, and the signals from such sensors are processed by a computer which regulates an adjusting unit for the force applying devices so that the pattern of temperatures along the external surface of the liner matches an optimum pattern.

  • Patent number: 4171107
    Abstract: A winding-up device for paper webs, especially wide paper webs, on a driven cylinder with a guiding roller which is adapted in response to an increase in the diameter of the wound up web material by means of two cylinder-piston units to be tilted away from the cylinder shaft while a constant distance is maintained between the guiding roller and the surface of the wound-up webs. The device comprises two pitot heads or tubes respectively radially directed toward each end of the cylinder and toward the wound-up webs. The device furthermore comprises two converter containers individually connected to the cylinder chambers on both sides of the piston of the hydraulic cylinder piston units, and acted upon by different pressures. The winding-up device also has a 2/2 way valve and a parallelly arranged check valve while the pitot head and the converter containers are adapted together to be connected to a compressed air network.
