PCT No. PCT/FI92/00267 Sec. 371 Date Aug. 8, 1994 Sec. 102(e) Date Aug. 8, 1994 PCT Filed Oct. 2, 1992 PCT Pub. No. WO93/07056 PCT Pub. Date Apr. 15, 1993.An apparatus for filling a sack with a flowable material, comprising a container having an inlet and an outlet and a sack holder to fasten the sack to be filled to the outlet of the container. The object of the invention is to provide a new apparatus for effectively filling a sack with a flowable material, eliminating the drawbacks of the known apparatuses. This is achieved by making the cross-section of the container (1) at least essentially correspond to the cross-section of the sack (5) in a filled condition; by making the wall (7, 8) of the container (1) enclosing the flowable material at least to an essential part permeable to air; by arranging means (13, 14) to suck air out of the flowable material through the air permeable wall (7, 8); and by arranging means (15, 16) close to the sack holder (4) below the outlet of the container to keep the sack closed during the suction of the air, with the exception of the mouth (6) of the sack fastened to the outlet of the container, and to open the sack to receive the flowable material after completed suction of the air. |
