[origin: US4908958A] PCT No. PCT/EP88/00018 Sec. 371 Date Oct. 5, 1988 Sec. 102(e) Date Oct. 5, 1988 PCT Filed Jan. 12, 1988 PCT Pub. No. WO88/05478 PCT Pub. Date Jul. 28, 1988.A drive for the guide roll of a drying felt or wire in the drying group of a paper machine, or the like. A gear transmission drives a selected one of the paper web guide rolls, which may be a drying cylinder, in a first group of rolls. The felt or wire is wrapped around a second group of rolls comprising felt or wire guide rolls. The one felt or wire guide roll located nearest the gear transmission is connected to the shaft of a drive gear of the gear transmission via a belt drive connection. Thus, rotation of the drive gear of the gear transmission via the gear transmission drives the one selected driven roll of the first group, and via the belt drive connection drives the driven felt or wire guide roll.
