Its other end is linked to a supply tube (42). There is a cleaning aperture (80) near the end of the feed tube or in a sector outside the hopper.A cleaning cartridge (86) can be connected to the cleaning aperture. This cartridge has a compressed air or water connection (90,92). The feed tube and/or the turning tube can be closed off by a lock (94,96,98) on the feed cylinder side.
