| description | The present invention refers to a laminated optical disc manufacturing apparatus (ODB) for manufacturing an optical disc (OD) by laminating at least a first substrate (6) and a second substrate (9). This apparatus (ODB) comprises adhesive coating means (100,300,400,500) for coating an adhesive (PP) between said first and second substrates (6,9) and forming an adhesive layer (CA,AS) having a specific thickness (Da) and a defoaming means (13) for removing bubbles intermixed with the adhesive (PP) at a second specific temperature (T2) that is higher than the first specific temperature (T). Moreover, an adhesive supply means (100) is provided to supply the adhesive (PP) controlled to have a first specific temperature (T) to said adhesive coating means (100,300,400,500). In another aspect a laminated optical disc manufacturing apparatus is provided that comprises means for suctioning the adhesive layer formed between the substrates. In another aspect a laminated optical disc manufacturing apparatus is provided that comprises centering means having at least two pins of a length sufficient to contact simultaneously the inside edges of the substrates such that the offset may be corrected. |
