Abstract
Abstract The subject matter of the present invention is a feed door for a baling press with a vertical work direction, where at one press case there is fastened a press door tiltably at hinges, in order to bring material to be pressed into the work room of the baling press. The invention has the object to improve the feed door such that a large dimensioned feed opening is created upon formation of a lower support table attached horizontally tiltable at the press case, without that the feed door required for this purpose leads to a hindrance for the user of the press. For resolving the object set forth, the invention is characterized in that the feed door is separated along a horizontal line and comprises a lower and an upper part.
