  • the invention concerns an equipment and a method in handling of doctor blades for a roll in a paper/board machine.
  • doctor blade is an important part which secures the operation of a paper/board machine, which blade, fitted in connection with a roll, maintains the condition of the roll face and permits the passing of a web portion that is to be passed into the pulper out of connection with the roll.
  • doctor blades have been stored in connection with the paper /board machine on various shelves for doctor blades, from which shelves the doctor blade has been lifted straight into the doctor blade holder construction.
  • a separate storage carriage which comprises at least one roll of doctor blades from which the doctor blade can be unwound.
  • the doctor blade material placed on the roll can be unwound through a separate measurement device and through a cut-off device.
  • the cut-off device comprises a measurement device in its connection, from which measurement device the pulled-out length of the doctor blade and the residual length remaining in the roll can be read. At the desired point, the feed of the doctor blade from the roll is stopped, and the doctor blade is cut off to the desired length.
  • the roll of doctor blades has been fitted around a shaft, which has been mounted revolving, and the band of doctor blades is passed through separate guides to the cutoff device, and a measurement detector of the measurement device is placed in direct vicinity of the cut-off device, which measurement detector measures the blade length 2 that has been fed. From a display placed in connection with a central unit, it is possible to read the blade length that has been fed out, and further, from the display it is possible to read the blade length that remains on the roll of doctor blades.
  • the roll of doctor blades is placed in a separate carriage, which can be shifted into different locations in connection with the paper/board machine.
  • the same carriage can be used in different locations while the carriage comprises a number of different rolls of doctor blades and separate cut-off means and measurement detectors for said rolls of doctor blades.
  • Figure 1 is an axonometric view of a storage carriage for rolls of doctor blades, which carriage comprises, in accordance with the invention, separate positions for different reels of doctor blades or rolls of doctor blades as well as, for each roll, separate cut-off devices and measurement detectors for the device for measurement of the length of the doctor blade.

Abstract

L'invention concerne un équipement et un procédé de manipulation de lames de racloir destinées à une machine à papier/carton. On place la lame de racloir (T) contre la surface d'un rouleau dans une machine à papier/carton de façon à garder cette surface propre et permettre sa maintenance. On prend une ébauche de lame de racloir (T) dans une bande enroulée de lames de racloir (10a1, 10a2, 10a3 ...) formant une bobine. Cet équipement comporte un dispositif de coupe (14a1, 14a2 ...) destiné à couper le matériau de lame de racloir à la longueur de coupe ou de lame voulus.
