Apparatus and method for filling cavities with particulate material

The apparatus for filling cavities with particulate material comprises a conveyor belt (1) comprising an orifice (10). The orifice is adapted for accommodating particulate material and for dispensing the particulate material through the orifice. The apparatus further comprises a first and a second guiding wheel (2,3) for transporting and guiding the conveyor belt. The first and second guiding wheels are arranged at a distance to each other and such that the conveyor belt comprises a straight belt portion (12) arranged between the first and the second guiding wheel. A retention element (15) is arranged adjacent the lower side (11) of the conveyor belt for keeping the orifice closed before the orifice reaches a transfer location (100) at the first guiding wheel. The retention element and the straight belt portion are further arranged to allow particulate material in the orifice to be dispensed through the open orifice at the transfer location, wherein the particulate material is transferred to the conveyor belt through the first guiding wheel.
