Abstract
Abstract Inturned lips alongside the wire slots provide ''''selfcleaning'''' slots which prevent cardboard flaps and the like from extending upwardly between the edge of the platen and the baling chamber at the slot to obscure a wire channel on the underside of the platen. A notch in the platen to accommodate each pair of inturned lips also assists in providing the self-cleaning slots. Thus, the compressed bale may be tied without releasing the pressure of the platen and also before any wall of the baling chamber is opened. A latch having a hook-shaped cam is adapted to latch the pivoted front door in closed position, the cam engaging a cam roller mounted on a front post. Lock pins on a side door interfit with holes in the front door, so that the latch may hold both doors in closed position.
