发明名称 BALING PRESS WITH PREPRESS VALVES
摘要 A baling press provided with a pressing box, a feed chute connected with the pressing box via a passage, at least two prepress valves. The prepress valves are each pivotable about pivotal axis, provided with a flat wall which in closed position closes off the passage from the feed chute to the pressing box and in opened position is disposed in the wall of the feed chute, and with a surface substantially curved about the corresponding pivotal axis, which surface in closed position bounds the feed chute in axial direction. One of the prepress valves is provided with a connecting surface which in the closed position is curved about a pivotal axis of one other of the prepress valves. In that closed position, the connecting surface is disposed at a distance from the curved surface of said other prepress valve which is at most minor and substantially constant. The invention provides a possibility of avoiding material to be pressed getting stuck between the prepress valves when the prepress valves are being closed.
