Abstract: A tracking apparatus and method for urging a mistracking conveyor belt back towards a correct travel path are provided. The apparatus and method both utilize downstream shifting of an end portion of an idler roller due to mistracking of the conveyor belt for directing or steering the belt back toward its correct travel path and a reaction force from the belt due to the steering thereof for energizing a tilting action of the idler roller to raise the downstream end portion thereof. In this manner, the tilting of the idler roller is not mechanically coupled to the downstream shifting of the roller end portion allowing the belt tracking apparatus herein to be bi-directional for use with conveyor belts that may be run in opposite travel directions.

Abstract: A conveyor belt tracking apparatus is provided for correcting the travel path of a laterally mistracking conveyor belt. In one form, an elongate tracking roller is rotatably mounted at end portions thereof to a pivotal support frame and extends across and below the belt. The pivotal support frame is mounted to a downstream pivot member so that belt mistracking toward one end portion of the tracking roller causes the one end portion to shift downstream and laterally outwardly to urge the belt toward the correct travel path. In one approach a downstream pivot connection between the pivot member and pivotal support frame is inclined upstream so that the end portion also shifts upwardly as it shifts downstream to urge the mistracking belt edge toward the correct travel path.

Abstract: Hitch guards are provided for spanning a gap formed in a conveying surface between two adjacent rollers. In one aspect, the hitch guards include hitch guard members positioned side-by-side along the gap. An elongate mounting member extends across the conveyor belt and has the hitch guard members releasable mounted thereto. In another aspect, an elongate hitch guard member extends across the belt width in the gap and includes a laterally elongated recess to capture debris.

The upper elongate member can be releasably latched to the lower elongate member for quick connection and removal therefrom. A cutting blade of the apparatus is preferably provided with upper and lower guides to increase the rigidity thereof for increasing cutting accuracy and allowing thicker belts to be cut therewith without increasing blade thickness.

Abstract: A belt lacer uses a power drive carriage for clinching hook or C-shaped belt lacing elements to a belt end. Optionally, the carriage may be driven in a manual mode or a power mode. A detachable power drive such as from an electric drill may be used for the power mode. The power drive of the carriage may be stopped short of an end wall and a return mechanism may return the carriage to the power drive. A moveable belt support in a hand space position allows for working on the lacing elements and may be shifted to a belt supporting position. The belt clamp exerts a forwardly directed force on the belt as it is being clamped. Face plates or combs may be stored on the belt lacer. A latch secures the face plates against lateral sliding during clinching by clinching rollers on the carriage.
