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.
