Abstract

For the manufacture of high pressure laminates, the pressed laminate (4) consisting of a stack of artificial resin impregnated paper sheets is fed into a single daylight hot press. The pressed laminate is held and guided along both longitudinal edges (6) by transfer clamps (7), which are connected to an endless rotating chain (8) and are conveyed on guide tracks (15). The transfer clamps (7) remain closed during the transfer into the single daylight hot press, during the pressing process and during a following cooling process in a cold press.
