发明名称 METHOD FOR GLUING OPTICAL DISC SUBSTRATES TOGETHER
摘要 A method for gluing two disc elements together, in particular substrates for digital audio, video or data discs, such as Digital Versatile Discs (DVDs). The disc elements are held essentially horizontally and coaxially with one another so that a gap is formed between the disc elements, after which, in an inner area of the gap, a liquid adhesive is applied in the form of separate strands in the circumferential direction on the facing sides of the disc elements. The disc elements are brought together against one another and made to rotate rapidly in conjunction with the bringing together in order, by the gravitational force of the upper disc element and the capillary force of the adhesive, in association with the centrifugal force on the latter during the rapid rotation, to form a homogeneous and bubble-free adhesive layer of predetermined thickness between the disc elements.
