Abstract
A machine for molding plates, especially plates of plastic materials, provided with one or more pairs of rollers that rotate synchronously in opposite directions, between which the plates to be processed pass, essentially characterized in that the rollers present their curved surfaces cut longitudinally , or circumferential, or mixed, in such a way that the rollers that make up the same pair present conjugated male-female carvings, rotating permanently in suitable relative arrangement due to the aforementioned synchronism effect, achieved for example by means of gears, being able to vary the distance between them. rollers that integrate each pair by transverse displacement of their bearings by suitable means such as spindles, a preheating chamber being provided for the plates, or preferably a train of appropriately heated rolls.
