A method of bonding together a first disc element (1) and a second disc element (2) with the aid of glue (10) to form a DVD comprises applying a quantity of glue (10) in the form of a ring on the first disc element, said ring being disposed concentrically with a center hole through the first disc element (1), and moving a second disc element, which also has a center hole and which is parallel with the first disc element, towards the glue ring in parallel with said first disc element and with the centre holes of said disc elements in coaxial alignment, such as to enable the glue to spread between the surfaces of the disc elements through the effect of pressure and capillary action. A center peg (14) is inserted sealingly in the centre hole of the first disc element and the glue ring is applied in contact with the perimeter surface of the peg.
A method of bonding a first disc element to a second disc element with the aid of glue to form a composite disc, comprising inserting a center peg sealingly in a center hole of the first disc element, applying a quantity of glue from a dispenser on the first disc element in the form of a ring in contact with a peripheral surface of the peg, the ring being disposed concentrically with said center hole through said first disc element, and moving a second disc element, which also has a center hole and which is parallel with the first disc element, in parallel with the first disc element during coaxial alignment between the center holes of said disc elements such as to enable the glue to be spread between the surfaces of the disc elements as a result of pressure and capillary action.
A method of bonding a first disc element to a second disc element with glue to form a composite disc, comprising the steps of:
