A drive gear for a group of cylinders and a method in the drive of cylinders in which the drive gear has a box frame including a front plate, a rear plate, and side plates, and to which box frame, rotational drive is introduced from outside the gearbox through a shaft. Rotation of the shaft causes rotation of a cogwheel and further, two other cogwheels are rotated which are in contact with this cogwheel, and the drive is transferred to both sides of the gearbox and further to the cylinders. The box frame of the gearbox is stationarily supported on a foundation which receives the weight of the gearbox shafts and cogwheels and the weight of the box frame. The load arising from the weight of the gearbox is transferred to the foundation through the box frame of the gearbox. Two cylinders and their shafts can be operated so that, between the shafts and the gearbox, there is a floating coupling which permits certain angular changes for the shafts of the driven cylinders. In this manner, torsion arising from faults in the directions of the shafts is not transferred from the cylinders to the gearbox or from the gearbox to the cylinders.
