Square-type sheet machine press 40cm square press

This press couches and squeezes water out of paper sheets produced on a sheet machine. A plunger-type pump is employed, which sends stored glycerin to the rubber diaphragm at the press section when the pump handle is operated. The diaphragm then pushes up the lower pressure board to compress the specimen. Improvement has been made with the stability while applyingpressure to achieve squeezing with a higher pressure.
