Abstract

A press and a method to laminate board-shaped work pieces via pressure and heat is provided. The press includes an upper press table 1 having an upper press plate 7 and a lower press table 2 having a lower press plate 10, and the upper and/or the lower press plate can be heated. The press further includes a one or two-part encircling gasket 16, 17, arranged at the upper press table 1 or the upper press plate 7 and/or the lower press table 2 to form a vacuum pressure chamber when the press is closed, an actuator 4 to open and close the press, as well as a vacuum source connection to evacuate the vacuum chamber formed by the seal 16, 17. According to the invention the lower press plate 10 can be raised in reference to the lower press table 2 and is arranged such that a work piece 6 located in the press initially does not contact the heated press plate 7, 10 when the vacuum pressure chamber is closed. The lamination method according to the invention is therefore embodied in two steps: first the vacuum pressure chamber is evacuated and only then is the work piece hot pressed.
