The unit has lateral guides provided in guiding plates (15) via a spiral-like recess (16), where the guiding plates are arranged at a distance of approximately 25 mm from a lateral pit wall. The spiral-like recess is formed such that guiding rollers (17) are adjustably provided in a cover. The spiral-like recess is formed in the guiding plates by laser cutting, where the cover includes a girder with a connecting unit i.e. conveyor chain. |
