Abstract
A method for bonding two DVD halves ( ) which are so held at a distance as to form a gap therebetween, includes introducing into the gap an adhesive ( ) and spreading the adhesive across both disc halves. The invention is characterized by introducing the adhesive via a central opening of the DVD by means of e.g. L-shaped metering needles ( ) which are pivotally guided in a central pin that engages the central opening, or flexible plastic needles which are slidably guided in a guide tube. Through introduction of the adhesive via the central opening enables a flow to the outside, without interference from the metering needles, when the DVD halves ( ) rotate. There is no buildup of adhesive in front of the metering needle. The bonding process can be carried out without interruption of the application of adhesive until the spin-off has concluded.
