Also the machine-direction form profile of the nip can be defined if required. After this, the sensor is reset again and the level of the linear load of the second nip N2 is measured.
  • the sampling rate of 8,000 measurements/second is achieved so several measurements in the same cycle can be implemented with regard to this.
  • the tension profile of both nips Nl, N2 is measured with the same sensoring as shown with arrows II. The measurement is made as above, but the sampled data describing the profile is recovered as the spiral goes through each nip.
  • the spirals are very low, the cover in the direction of the periphery is advantageously shorter than the distance between the nips of the primary and the secondary reeling. Also the total profile of the linear load can be calculated from the signal of the spiral sensor.
  • Fig. 19 shows the measuring of a web tension profile with the measuring arrangement utilised in connection with the method and the reel-up according to the invention.
  • the measurement can be performed using the installation alternative according to Fig. 15, in which the total level of web tension is measured before the secondary nip or by using the installation alternative according to Fig. 16 in which a tension profile is measured.
  • web tension or a web tension profile can be measured depending on the construction between the primary and the secondary nip or before the primary nip. The sampling can be focused on the periphery to the point in which the measurement is wished to be made.
  • a new operational area enabled by a large-diameter reeling cylinder according to an advantageous embodiment of the invention becomes evident.
  • the proportion of the diameter of the reeling cylinder to the width of the web being reeled is on the vertical axis y of the figure and the web width is on the horizontal axis.
  • This embodiment also provides extra space for change devices especially when the reeling nip is closed, and there is also more space for different actuators in the frame.
  • a brake 60 has been arranged into connection with the reeling cylinder 10 which brake is available for use during reeling for damping the nip vibration so that no effects are created in the nip force measuring.
  • the brake 60 prevents the reeling cylinder 10, which moves on an inclined surface, from uncontrollably moving downwards.
  • the brake 60 is positioned into connection with the loading/moving actuator of the reeling cylinder 10 between the nip-force measuring and the loading actuator 65, whereby it has no effect on nip-force measuring nor causes problems in adjusting the nip force.
  • the brake force of the brake 60 can be adjusted so that during reeling the brake 60 is used with a set small, nip-vibration damping force and in failure situations if required with a force preventing the uncontrollable movement of the reeling cylinder 10.
  • the brake 60 can be e.g. a spring-loaded hydraulic brake.
  • a brake according to an embodiment comprises a friction shoe which is arranged for braking against an arm of the actuator or along a sliding block fastened in the loop of the actuator.
  • the brake can also comprise a combination of a screw and a hydraulic cylinder which comprises an active brake part/damper.
  • Brake-force measuring can be arranged into connection with the friction surfaces of the brake, whereby e.g. there is a brake part between the loop of the hydraulic cylinder and the force sensor from which braking is done with brake shoes.
  • brake-force measuring is also applicable to be utilised in other paper- and board-machine devices, such as e.g. surface-gluing, pigmenting or coating film-transfer presses, calenders, on the press and in reel-ups utilised in connection with slitter-winders.

Abstract

L'invention concerne un procédé de bobinage de bande de papier ou de carton, selon lequel la bande (W) est enroulée autour d'un arbre de bobinage (21; 24) pour former un rouleau de bande (22; 20) à l'aide de la ligne de contact entre un cylindre de bobinage (10) et le rouleau de bande formé (22, 20), le bobinage s'effectuant dans un étage primaire dans une position primaire et dans un étage secondaire dans une positon secondaire. Dans ce procédé, le cylindre de bobinage (10) est sensiblement transféré dans la direction correspondant à la direction d'arrivée principale (SlO) de la bande arrivant au cylindre de bobinage et le rouleau de bande formé (20, 22) est transféré de l'étage primaire à l'étage secondaire dans un mouvement sensiblement horizontal. De plus, l'invention concerne un procédé dans lequel la bande de papier ou de carton est enroulée à l'aide d'un cylindre de bobinage à grand diamètre (10), la proportion du diamètre du cylindre de bobinage (10) par rapport à la largeur de la bande en cours de bobinage étant définie de manière ce que la zone opérationnelle sélectionnée se situe au-dessus de la courbe définie par l'équation y=- 0,0009x3 + 0,025x2 - 0,2567x + 1,0903, dans laquelle y = diamètre du cylindre de bobinage/largeur de la bande en cours de bobinage et x = largeur de la bande en cours de bobinage. L'invention concerne en outre une enrouleuse qui sert à enrouler une bande de papier ou de carton en un rouleau de bande, et qui comprend des moyens pour transférer le cylindre de bobinage (10) dans une direction (SlO) qui correspond sensiblement à la direction d'arrivée de la bande (W) arrivant au cylindre de bobinage (10), ainsi des moyens pour enrouler le rouleau de bande dans la position primaire et des moyens pour enrouler le rouleau de bande dans la position secondaire, lesquels moyens sont disposés de sorte que le déplacement du rouleau de bande formé (22) de la position primaire à la position secondaire soit sensiblement droit dans la direction horizontale. Par ailleurs, l'invention concerne une enrouleuse dans laquelle la proportion du diamètre du cylindre de bobinage (10) par rapport à la largeur de la bande en cours de bobinage soit définie de sorte que la zone opérationnelle corresponde à l'équation y=-0,0009x3 + 0,025x2 - 0,2567x + 1,0903.
