Abstract
A paper making machine for producing a continuous traveling fiber material web includes a roll having a longitudinal axis and two longitudinal ends. Each end has a concentric first circular gear with a plurality of radially outwardly facing teeth. A felt is carried by the roll. The paper making machine also includes a pair of parallel lower elongated racks extending substantially perpendicular to the longitudinal axis of the roll. Each lower elongated rack includes a plurality of teeth carrying and meshing with the teeth of a respective first circular gear. The roll is rotatably movable with respect to the lower racks in two opposite directions along and parallel to the lower racks and transverse to the longitudinal axis of the roll. A first of the two opposite directions is toward the felt. The paper making machine further includes a device for rotating and thereby moving at least one first circular gear along a respective lower rack such that the felt is stretched in the first of the two opposite directions.
