Abstract
A platen press, especially a multiplaten press has peripheral seals around the press platens to seal off the pressing gaps containing the wood material mats to be pressed on suction passages formed between the platens and communicating suction ducts at the upper or lower sides of the press, whereby fibers are evolved from the mats and are drawn off through these passages and conduits without significant dilution with ambient air or air serving to cool the platens for destruction by combustion.
Claims24
A platen press comprising:
- a press head at an upper side of the press and a press bed at a lower side of said press, one of said press head and said press bed being fixed;
- a plurality of platens disposed one above another between said upper and lower press sides and defining press gaps between them for receiving wood-containing mats and pressing said mats to form boards;
- seals between said platens all around peripheries of said platens and said gaps for sealing said gaps upon closing of the press;
- passages formed in said platens and communicating with one another and with said gaps inwardly of said seals for forming at least one upright evacuating duct;
- and
- at least one suction conduit on one of said sides of said press and communicating with said duct at least in a closed position of said press and through a passage for said passage in a respective one of said platens proximal to said one of said sides for evacuating gases evolved from said mats during pressing thereof.
