Abstract (en)
[origin: WO9907542A1] The invention relates to a method for sticking two halves (23, 24) of a dvd (digital versatile disc). Said halves are held at a distance from each other so that a gap forms between them. The adhesive (36) is then introduced into said gap and is spread over both halves. The invention is characterised in that the adhesive is introduced via the central hole in the DVD by means of e.g., L-shaped metering needles (63) which are pivotably guided in a central pin, said pin dipping into the central hole (51), or flexible plastic needles which are guided in a guiding tube in such a way that they can move. Introducing the adhesive via the central hole means that the adhesive can flow freely out of the metering needle as the DVD halves (23, 24) turn. There is no build-up of adhesive in front of the metering needle and the sticking process can continue until the spinning process is complete, without any interruption of the application of adhesive.
