A process for producing a DVD from two DVD substrates A and B, wherein the first substrate (A-disc) of the DVD is produced by a first injection unit A and the second substrate (B-disc) of the DVD is produced by a second injection unit B, wherein one or both DVD substrates are coated, in particular metallised, in a coating station, wherein one or both DVD substrates are provided with an adhesive in an adhesive application station and wherein the DVD substrates A and B are supplied to at least one joining station for the purpose of joining the A-disc and B-disc to form a DVD. The invention is characterised in that at least one walking beam (12) is provided for transporting the DVD substrates A and B through the production line, in that the A-disc and the B-disc are alternately located behind one another in a row (A-B-A-B-A-B- . . . ) on the walking beam (12), and in that the walking beam is operated in double step fashion. In this way, the A substrates are always in the one same position, whereas the B substrates are always in the other same position which makes title tracking possible without sensor and software expenditure. |
