DEFINITION

Classification: 162/257

(under subclass 256) Apparatus in which the controlled motion of the foraminous forming surface is in a plane normal to the length of the surface.

(1) Note. In this subclass may be found, for example, devices for either causing or preventing lateral shift of a traveling Fourdrinier wire.

101+, and in particular subclasses 102+ for mechanism in which the invention relates to devices for maintaining a flexible band in predetermined paths of travel. This class (162) provides for devices in which positive cyclical shifting motion is imparted to a forming belt to prevent wear on the surface over which it slides, and in addition to control the tracking of the forming belt.
