Abstract: An apparatus for loading and unloading a multiopening press for manufacturing fibreboard comprises a first endless conveyor movable through an upper opening of a press having upper and lower openings with an intermediate plate therebetween. The first endless conveyor is formed of a plurality of conveyor sections which are spaced along the first conveyor and connected together by at least one drive member. A second endless conveyor is movable through the lower opening of the press. The first and second conveyors move along first and second feed paths through the upper and lower opening of the press respectively. The first conveyor however intersects the second feed path with the at least one drive member positioned on the first conveyor to permit passage of a mat for making a fibreboard on the second feed path to the second conveyor when each of the conveyor sections is spaced away from a location of intersection of the first conveyor and the second feed path.

Abstract: An apparatus for a double opening press useful in manufacturing particle board comprises an upper and intermediate movable plate and a lower fixed plate and a chain of levers connected between the upper and intermediate plate. Upper and lower spaces are defined between the intermediate plate and the upper and lower plates respectively. A driving unit is connected to the upper plate which lowers the upper plate and which, simultaneously, through the action of the chain of levers, also lowers the lower plate at a rate which is chosen so as to close the upper and lower openings at the same speed.
