Process for dewatering wet cardboard and the like like
The subject of the invention is a further development of the method according to patent no.115901: it is essentially characterized in that the heat is supplied to the pressed material by means of electrical resistance heating using the sieves or full shed as electrodes that divide the stack of pressed material.

In the case on which the illustration is based, a hydraulic press 1 is used for dewatering, on the table 2 of which the wet cardboard panels are placed. 3 can be set up. this happens
