  • Method and apparatus for measuring web tension profile to control the reeling of a web
    Patent number: 6629659
    Abstract: A method and apparatus for reeling or winding of a web in which one or more factors affecting the web in the reeling or winding process are controlled by means of measurement data in order to affect the quality of the reel or roll formed in the reeling or winding process. The is measurement data used is the web tension profile of the web brought into the reeling. The web tension profile is measured by means of a measuring device from which the web tension profile data is transmitted to a data processing unit which adjusts the factors affecting the web during reeling or winding.

  • Method for determination of an irreversible stretch and of a dynamic modulus of elasticity
    Patent number: 6517679
    Abstract: The invention concerns a method for determination of an irreversible stretch and of a dynamic modulus of elasticity from a paper web (W). In the method, the irreversible stretch and the dynamic modulus of elasticity are determined from h paper web (W) by means of on-line measurement. The invention also concerns a method in which the quantities that have been determined are employed in the control of the papermaking process.

  • Method and apparatus for threading of paper or paperboard web
    Patent number: 6395135
    Abstract: In the method for threading of a paper or paperboard web a narrower tail (T) separated from the paper or paperboard web (W) is conveyed between different holding points. On the travel path of the tail (T) there is at least one tension measuring device (1) which is arranged to measure the tension of the tail (T) passing by, said device (1) being connected to a data processing unit (7) which is connected to tension control means affecting the tail (T). The threading can be conducted on a tension level lower than the actual running tension of the full-width web (W).

  • Method for producing calendered paper
    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.
