Open the CIPO recordAbstract From the Canadian patent
An apparatus which controls the lateral alignment of a belt arranged to move in a pre-determined path. A pivotably mounted belt support is frictionally driven to move in unison with the belt. Lateral movement of the belt applies a frictional force on the belt support. The frictional force tilts the belt support in a direction so as to restore the belt to the predetermined path of movement.
