  • Patent number: 5102238
    Abstract: In a device for the quick change of a shaft, e.g., the shaft of a coil in web coating apparatus, the shaft of the coil is equipped at the ends with ball bearings which, after the change, are fixed in a bearing holder. To be able to perform the change simply, the seat of the bearing is multipartite. The two upper halves of the bearing holder are shaped so that the bearing automatically opens and closes when the shaft is changed. The lock-up of the bearing holder is signaled electrically at the switchboard.
