Conveyor unit for moving flat objects has conveyor path restricted relative to second of two endless conveyor belts through a third endless conveyor belt which can be driven at same speed

摘要

The conveyor unit has a first and second endless belt (4,6) whereby the first belt extends along part of the circumference of a cylinder (7) whilst the conveyor path is restricted relative to the second endless belt (6) through a third endless belt (5). The third endless belt can be movably coupled to the second belt and can be driven at the same speed as same. The second and third belts can be coupled to the cylinder through a transmission ratio.
