PCT No. PCT/SE87/00338 Sec. 371 Date Jan. 23, 1989 Sec. 102(e) Date Jan. 23, 1989 PCT Filed Jul. 16, 1987 PCT Pub. No. WO88/00908 PCT Pub. Date Feb. 11, 1988.A method and an apparatus for emptying packages, especially bags, of their contents is described. The bags are introduced through a casing (2) to a rotatable cutting, tumbling and feeding screw (4) for cutting, the contents of the cut bags (54) being removed through perforations (28) in the casing or wall portions (6) associated therewith. Separation is achieved by rotating the screw (4) in a first direction (B) for advancing the cut bags (54) to an end wall (6) of the casing (2) adjacent a rear end (62) of the screw where the bags are caused to tumble about within the casing (2) under the action of the screw rear end rotating in said first direction (B), for separating the contents from the cut bags (54). After the separation at the screw rear end has been concluded, the screw (4) is rotated in a second direction (F) for advancing the emptied bags (33) in a direction toward the screw front end to a bag discharge opening (36) which is provided in the casing (2) and through which the emptied bags (33) are discharged from the casing (2). |
