ADHESIVE APPLYING DEVICE FOR ADHERING OPTICAL DISK

摘要

PURPOSE:To improve the flatness of optical disks after sticking by applying an adhesive thereto always at a specified thickness regardless of the thicknesses of the disks. CONSTITUTION:The adhesive for adhering the optical disks of the adhesive applying device for sticking the optical disks to each other is deposited on the surface of a revolving upper roller 23. The optical disks are transported into a spacing part between this upper roller 23 and a lower roller 24 and the adhesive is supplied from the upper roller 23 and is applied on the surfaces of the optical disks. The thicknesses of the optical disks are detected by a disk thickness detecting section 30 and the distance of the spacing between the rollers is controlled by the detected signal, by which the spacing between the surfaces of the optical disks and the upper roller 23 is maintained always constant.
