Abstract
An inversion apparatus uses a first pair of bend rollers to twist a conveyor belt 90.degree., and a second pair of bend rollers to twist the conveyor belt an additional 90.degree.. The two bend rollers of each pair are rotatably mounted at rotational axes which are perpendicular to each other. Preferably, stabilizer rollers are provided between the bend rollers of each pair, and cylindrical rollers are provided to feed the conveyor belt to and from the bend rollers. The stabilizer rollers and bend rollers are preferably curved so as to equalize the tension across the width of the belt.
