Abstract: A tracking assembly for tracking belts and webs comprises a support frame which is adapted to be mounted below a traveling belt or web. A straight or angled support shaft is pivotally mounted at its center via a post which is rotatable within bush on the support frame. A selected arc of rotation of the post within the bush is determined by an adjustable limit stop arrangement which can take the form of a pair of grub screws. A roller is mounted onto each end of the shaft. The two rollers have tapered ends. When the belt or web travels off center it will come into contact with the tapered end of the roller on the side to which the belt has moved. This will cause the shaft to pivot about a vertical axis of the post and thereby steer the belt back to a central position.

Abstract: A tracking assembly for mounting to a support frame of a conveyor belt installation in order to keep the conveyor belt which travels thereon centrally aligned includes a sub-frame adapted to be mounted to a support frame of a conveyor belt installation. A plurality of independently rotatable idlers are mounted for rotation on the sub-frame to support the conveyor belt of the installation in position. The idlers are aligned generally parallel to each other spaced apart from each other across the width of the belt, with the sub-frame and idlers being mounted to the support frame generally transverse to the length of the belt. Each of the idlers include a support shaft, an outer drum rotatably supported on the shaft, and a pivot assembly located within the drum defining a pivot axis about which the drum is pivotable relative to the shaft, the pivot axis being perpendicular to the belt which in use travels on the idler.
