Description

TRUE COPY LODGED « 0 9 0 358 Baling Press for Tyres This invention relates to h baling press and in particular to a baling press for compressing ( **«·? ί Τ'. ** ‘‘ T'iJ C 9? ! and baling waste tyres. | c,.«<,,- . . ... · 4.«» <. j * Waste material baling prg^^'ffiWn^orWmpressfhglndtalin^ waste material for disposal or transportation whereby the waste material is compressed to take up less volume.
Such presses typically comprise a press box delimited by a base, upstanding side walls and a 10 press platen defining an upper wall of the press box and being arranged to be moveable into the press box under the action of an actuator means, typically one or more hydraulic rams, to compress material placed into the press box.
Slots are typically provided in the boundary walls of the press box to allow the compressed 15 material to be wrapped with straps to retain the material in its compressed configuration.
Inwardly projecting retaining fingers or teeth are typically provided in the side walls of the press box for retaining the material in its compression state during said wrapping operation. Such retaining fingers are pivotally mounted to permit passage of the press platen there past and are typically spring biased to their extended position. Typically one side wall of the press box is openable in the manner of a hinged dKoTtoperpnf rernbv'al11 WYtK^baled waste therefrom. I . , ’ MP, ! c 5¾i 00 , Such known balers are typically used for baling fibrous and cardboard wasfe/Tor example waste cardboard boxes.
It is particularly desirable to compress waste tyres for transportation and/or disposal, since uncompressed tyres take up a lot of space due to their shape, construction and the resilient nature of the materials used. Furthermore, the resilience of such materials makes the materials resistance to compression. The resilient nature of such materials causes problems where convention baling presses are used to compress and bale waste tyres. In particular, the compressed tyres tends to rebound when the press platen is withdrawn, jamming the bale against the walls of the press box and against the underside of the retaining fingers, preventing removal of the bale from the press box.
IE Ο 9 Ο 3 5 8 According to the present invention there is provided a baling press for compressing and baling waste tyres comprising a press chamber for receiving waste tyres, said press chamber being define by a base, first and second end walls extending upwardly from opposed first and second sides of the base, first and second door members for closing front and rear openings between said first and second end walls, and a press platen moveably mounted above said base to be moveable towards and away from said base by means of an actuator, wherein both of said first and second door members are openable to permit removal of a bale from the press chamber. The press platen is arranged substantially parallel to said base to be moveable in a vertical direction.
