  • Patent number: 9302425
    Abstract: A method and apparatus for sealing a cut edge of a foam board is disclosed. The foam board has a top surface, a bottom surface, a first cut edge and a second cut edge. Each cut edge extends between the top and bottom surface. The method includes heating of at least one of cut edges to raise the surface to a first temperature, applying pressure to the at least one of the cut edges by a pressure source at a first pressure, and cooling the at least one of the cut edges to a second temperature. The first temperature is above the foam glass transition temperature and the second temperature is below the glass transition temperature.

  • Patent number: 6848357
    Abstract: A method for controlling the temperature of a heated roll in a calender is provided. The calender comprises at least one heated roll or thermoroll and at least one backing roll, between which is formed a nip through which the material web is conveyed. To the heated roll is supplied internal thermal power by internal heating means of the roll, and external thermal power by external heating means of the roll. Before changing the heated roll, internal thermal power is minimized within a specific period by control means provided in conjunction with the internal heating means; external thermal power is maximized within a specific period by control means provided in conjunction with the external heating means; and the surface temperature of and/or the thermal power released by the heated roll, which corresponds to the surface temperature and/or thermal power desired for the grade of the material web, is maintained within a specific period.

  • Patent number: 6349637
    Abstract: A magnetic calender comprises a pair of rotatable parallel rolls (1, 2) and an electromagnet provided with two pole pieces (6, 7) extending parallel to the rolls (1, 2) and joined to a common base (5) through a plurality of magnetic cores (8) having an arrangement which is specularly symmetrical with respect to both the transverse mid-plane and the longitudinal mid-plane of the calender. A coil (9) and a control solenoid (10) located adjacent to the relevant pole piece (6, 7) are wound around each of the cores (8), and the intensity of the current circulating in the coil (9) is controlled by an adjusting unit (11) which is in turn controlled by a control unit (12) which receives and processes the magnetic flux reading carried out by the control solenoid (10).

  • Patent number: 6264792
    Abstract: A method and apparatus for producing calendered paper by an on-line manufacturing system comprising at least a paper machine and a multi-nip calender. The method comprises following steps: removing water from a formed paper web by pressing, drying the pressed paper web by at least one dryer, calendering the dried web by the multi-nip calender, measuring a cross-machine moisture profile or a variable relative thereto, and altering the moisture of the web so that the moisture profile of the web in the cross-direction is even when the web enters the first nip of the calender.

  • Patent number: 6244171
    Abstract: Calender and process for operating the calender, calender roll and process for forming the calender roll, and a coating for the calender roll. The calender includes at least one calender roll body, and an elastic coating coupled to the at least one calender roll body. The elastic coating includes a colorant to change a color of the elastic coating depending upon a temperature of the elastic coating. The calender roll includes an elastic coating with a colorant, and the elastic coating is adapted to change color depending upon a temperature of the elastic coating. The process for forming the calender roll includes forming an elastic coating that includes a colorant, whereby the elastic coating changes color depending upon a temperature of the elastic coating, and applying the elastic coating to a calender roll body.

  • Patent number: 6230615
    Abstract: Calender for the treatment of a paper web including a roll stack of at least three rolls and with least one double-soft nip. The double-soft nip(s) are formed by two rolls, each with an elastic surface layer. At least one of the rolls forming the double-soft nip is heated. In a process using the calendar to treat a material web, the web is introduced into a roll stack having at least two rolls formed with an elastic surface layer over a rigid core, agglomerated in an elastic double-soft nip between the two rolls, heated to introduce energy into the material web and promote agglomerating, and smoothed in the elastic double-soft nip.

  • Patent number: 5983787
    Abstract: A method for calendering a paper web, including the steps of passing the paper web through a calendering nip having a profile formed from a pair of calendering rolls, wherein at least one of the pair of calendering rolls includes a soft exterior face at least in the region of the nip, regulating the profile of the calendering nip to compensate for flaws in the paper web passing through the calendering nip including varying the properties of the soft exterior face locally in a direction transverse to the direction of the passing paper web concurrently with the passing step.
