Abstract
The invention relates to a device for vacuum-pressing of disk-shaped substrates, in particular DVD substrates into a finished DVD, wherein the device has a vacuum chamber with two substrate holders and an intermediate element that can be displaced inside the vacuum chamber; and wherein the intermediate element divides the vacuum chamber into a first low-pressure chamber and a second chamber that can be alternatingly connected to vacuum or to an overpressure, which makes the device particularly suited for use with a hot-melt thermoplastic adhesive.
