In order that the grinding could be carried out easily and rapidly and with only a short downtime of the paper machine, the carriage of the device is formed by a frame carriage (1) which is provided with supporting elements (13) for the support thereof both against a drying cylinder (9) of the paper machine and against a second cylinder (10) of the paper machine so that it is positioned between said cylinders (9, 10) when the device is in operation. There are preferably eight supporting elements (13, 14) provided, four of which are arranged to be positioned against the drying cylinder (9) to be ground and the other four against the second cylinder (10). The supporting elements (13, 14) are provided with rotating balls, roller wheels or slide surfaces so that the cylinders (9, 10) of the paper machine are rotatable during the grinding process. |
