Claims
- 1-12. (cancelled)
- 13. A method in connection with the manufacture of a paper web or the like, or in a reeling up process of said web taking place in connection with an on-line or off-line finishing treatment of the same, in which a continuous web is reeled up on a centre-drive assisted reeling core to form a machine reel, in which reeling process the reeling core moves when the centre drive is coupled to the end of said reeling core, wherein the rotating movement and torque necessary in the centre drive are transmitted from the stationary drive motor to the end of the reeling core by means of power transmission equipped with one or more joints.
- 14. The method according to claim 13, wherein the rotating movement and the torque are transmitted from the drive motor to the end of the reeling core by means of power transmission utilizing belt drive.
- 15. The method according to claim 14, wherein the rotating movement and the torque from the output shaft of the drive motor to the end of the reeling core is transmitted by means of power transmission utilizing one intermediate shaft.
- 16. The method according to claim 15, wherein the speed of rotation of the output shaft of the drive motor and the shaft of the reeling core are adjusted to be suitable in relation to each other by changing the mutual size of the diameters of the belt pulleys.
- 17. The method according to claim 15, wherein the location of the output shaft of the drive motor and the location of said shaft and the intermediate shaft in relation to each other and the reeling core are selected in such a manner that the force effects substantially in the direction of the nip force that are caused by the transmission of the torque of the centre drive and the rotating movement are minimized.
- 18. A centre-drive device in connection with the manufacture of a paper web or the like, or in a reel-up used in connection with an on-line or off-line finishing treatment of said web, in which reel-up a continuous web is reeled up on a centre-drive assisted reeling core to form a machine reel, in which reeling process the reeling core moves when the centre drive is coupled to the end of said reeling core, wherein the centre drive device comprises a stationary drive motor as well as power transmission equipped with one or more joints to transmit the rotating movement and torque necessary in the centre drive to the end of the reeling core.
- 19. The centre drive device according to claim 18, wherein the power transmission comprises at least one power transmission belt to transmit the rotating movement and the torque of the centre drive from the drive motor to the end of the reeling core by means of a belt drive.
- 20. The centre drive device according to claim 19, wherein the centre drive device comprises at least:
a stationary drive motor; a first belt pulley arranged in the rotating output shaft of the drive motor; an intermediate shaft; a supporting member between the output shaft and intermediate shaft of the drive motor; a belt/belts for transmission of the rotating movement and torque of the first belt pulley to a second belt pulley arranged on the intermediate shaft; a third belt pulley arranged in the intermediate shaft and rotating at the same speed with the second belt pulley; a shaft whose rotating movement and torque are arranged to be coupled to the end of the reeling core by means of a coupling member; a supporting member between the intermediate shaft and the shaft; a belt/belts for transmission of the rotating movement and torque of the third belt pulley to a fourth belt pulley arranged on the shaft.
- 21. The centre drive device according to claim 9, wherein the mutual size of the diameters of the belt pulleys is selected in such a manner that the speed of rotation of the output shaft of the drive motor and the shaft of the reeling core are suitable in relation to each other.
- 22. The centre drive device according to claim 20, wherein the location of the output shaft and the intermediate shaft of the drive motor in relation to each other and the reeling core is arranged in such a manner that the force effects produced by the power transmission in the direction of the nip force and caused by the transmission of the torque and the rotating movement and that are parallel to the nip force are minimized.
- 23. The centre drive device according to claim 18, wherein said centre drive device is a primary drive device of a primary reeling device in a reel-up.
- 24. The centre drive device according to claim 18, wherein said centre drive device is a secondary drive device of a reel-up.
