A belt conveyor includes a conveyor belt configured to move in a longitudinal direction. The conveyor belt has two large faces, and a number of support stations distributed longitudinally along the conveyor belt. The support stations are configured to support the conveyor belt by one of the large faces. At least one support station includes a drive motor configured to drive the conveyor belt in the longitudinal direction relative to the support stations.

A conveyor system and related methods of operation for using two or more conveyors to treat at least two separate sides of food items with a chemical intervention solution. The conveyor system can include two or more conveyors arranged in an angled relationship relative to a horizontal plane such that a first side of a food material is presented on a first conveyor and a second side of the food material is presented on a second conveyor. A chemical intervention system including two or more spray assemblies can apply a suitable chemical intervention solution to the first and second sides of food. The two or more conveyors can be arranged at an angle from 20-45 degrees relative to a common horizontal plane.

A packaging machine for packaging products to be packaged using a stretchable film has a film transporter supplying the film. The film transporter has first and second belt conveyors that each have first and second transport belts, which are synchronously driven and arranged next to one another in a film transport direction. A belt conveyor is movable in a direction perpendicular to the film transport direction, and has a movable film guide to insert the film into the film transporter. The film guide has a guide plate for guiding the film. The guide plate has first and second recesses in an upper edge in the vertical direction facing the belt conveyors. The belt conveyors are to be inserted into a respective one of the recesses. The film transporter has cleaners for the belt conveyors.

A roller for a conveyor system comprises a nonlinear bore hole to facilitate retention of the roller on a roller-receiving portion of a corresponding shaft. A nonlinear bore hole comprises a central cylindrical portion for receiving a roller-receiving portion of the shaft and unaligned slots in communication with the central cylindrical portion to prevent migration of the roller from the roller-receiving portion.

A conveyor employs a low-tension, direct drive conveyor belt, and a position limiter assembly. The position limiter assembly includes a primary position limiter and a secondary position limiter. The primary position limiter provides line of contact engagement with the conveyor belt while the secondary position limiter has an extended, static limiting surface for engaging the conveyor belt if the conveyor belt disengages from a drive sprocket prior to the line of contact with the primary position limiter.

A belt conveyor includes: a belt which is supported, rotated and moved by a plurality of rollers, and which moves ore and a product; skirt means which are installed on both sides over the belt along a longitudinal direction, and which prevent the ore and the product from being scattered; impact bar means which are installed beneath both sides of the belt, and which rub against the belt and also support the bottom surface of the belt; and impact bar fastening means which are installed beneath the impact bar means, and which support the lower ends of the impact bar means; wherein the impact bar means are installed in transverse directions along the longitudinal direction of the belt, and the impact bar means are detachably installed in left-right directions.
