Filter/moulding press - for fabricating concrete building slabs

摘要

The press comprises two parallel spaced plates supported on a chassis across one of which plates is a chamber for containing the material to be pressed. An inflatable device is located between the plates and comprises a first diaphragm attached to one plate forming a chamber between itself and the other plate. A second diaphragm back to back to the first, and a third diaphragm serve to press the article against its support on the other plate. Fluid lines are connected to the diaphragms for inflating them.
