Abstract

This novel method adheres two substrates (3, 6) together, forming a disc (23). This product is especially a digital video disk (DVD). Adhesive is coated onto a surface of the first substrate (3), and the second substrate (6) is laid upon it. Specific sides are joined together in this way. The novel feature of this process, is that the combined substrates are rotated about their central axis, to eject adhesive. Also claimed is the corresponding equipment.
