  • DETERMINING ELASTIC MODULUS FOR CONTINUOUS MATERIAL WEB
    Publication number: 20120029844
    Abstract: A method and apparatus are disclosed for determining elastic modulus for a continuous material web, in which method a continuous material web runs on a roll driven by an electric motor drive. The method includes determining material web speed v2, providing a change in an adjustable characteristic of the continuous material web by the electric motor drive, the characteristic being material web tension T, torque M acting on the material web or material web speed v2, calculating elastic modulus E on the basis of the determined material web speed v2 and speed change ?v2 and torque change ?M or material web tension change ?T.

  • Arrangement and method for starting a machine
    Patent number: 7482942
    Abstract: An arrangement is disclosed for an industrial drive in which at least one machine or part of machine can be started from a location separate from the machine or part of machine. The arrangement includes an alarm device that can be activated before the part of machine is started. The arrangement includes two sources and two devices for controlling a sound source that can be activated before starting the machine so that the alarm sounds from both sound sources are intermittent and jointly include a substantially solid continuous sound.
