Abstract
An apparatus and method for guiding the transverse position of a fabric in a paper machine, such as a drying wire, a press felt, or an equivalent fabric having an alignment roll for the fabric. The axial alignment of the alignment roll is regulated by a guide apparatus. In the guide apparatus, a sledge is arranged in connection with one or both of the bearing supports of the alignment roll. The position of the sledge in relation to the frame part of the apparatus is regulated by an actuator motor. The sledge of the guide apparatus is arranged on linear guides in the frame part of the apparatus and is guided by guides. The apparatus further includes a self-holding power transmission arrangement operated by the actuator motor.
