Abstract
A filling device for bulk materials includes a filling hopper, a housing surrounding an open end of the filling hopper and two hopper outlet doors which are pivoted in the the housing. In order to achieve the object of further developing the filling hopper so as to enable loss-free operation to take place, the filling hopper or, respectively, a casing surrounding the same has an external encircling section. Furthermore rubber sealing strips are provided on the hopper outlet doors, which come into sealing engagement with the encircling section when the hopper outlet doors are moved by a control system into the open position thereof.
