The invention relates to a cooling station for disk-shaped substrates, especially for injection-moulded substrates of optically readable data carriers such as CDs, CD-RS, DVDs, CD singles, DVD singles and similar. At least three cooling spindles (2, 3, 4, 5) are provided and are set apart from each other and arranged parallel to each other in such a way that one substrate is contact with all of the cooling spindles simultaneously. Driving means (6, 7, 8) are also provided for rotating the cooling spindles. The invention is characterised in that each cooling spindle has at least two threads (9, 10) with thread undercuts of different widths. In this way, substrates of different thickness can be accommodated in the same cooling station, e.g., CD and DVD substrates. Alternatively or additionally, four or more cooling spindles can be provided and arranged in such a way in relation to each other that three cooling spindles are each provided with a particular diameter for transporting substrates. In this way, substrates with a different diameter, e.g. standard CDs and CD-singles, can be accommodated in the same cooling station. |
