Transfer lock for a tabletting plant

A transfer lock for a tight-locked casing of a tabletting plant, particularly a tabletting press, wherein the casing has side walls where at least one wall has an aperture which is adapted to be closed by a first flap which is pivotable inwardly into the interior of the casing and is adapted to be locked by an operable locking device, wherein the aperture is externally surrounded by a connection profile which is adapted to be sealingly brought together with a counter-profile of a lock channel and the flap externally has a driver profile which interacts with a counter-driver profile of a second flap mounted at the end of the lock channel when the counter-profile of the lock channel is connected to the connection profile, thus allowing to pivot the two flaps into the interior of the casing when the locking device is unlocked, characterized in that the connection profile (32) is integrated into the material of the casing wall (10, 16).
