    • A method for gluing two disc elements together, in particular substrates for digital audio, video or data discs, such as Digital Versatile Discs (DVDs). The disc elements are held essentially horizontally and coaxially with one another so that a gap is formed between the disc elements, after which, in an inner area of the gap, a liquid adhesive is applied in the form of separate strands in the circumferential direction on the facing sides of the disc elements. The disc elements are brought together against one another and made to rotate rapidly in conjunction with the bringing together in order, by the gravitational force of the upper disc element and the capillary force of the adhesive, in association with the centrifugal force on the latter during the rapid rotation, to form a homogeneous and bubble-free adhesive layer of predetermined thickness between the disc elements.
    • 用于将两个盘元件粘合在一起的方法,特别是用于数字音频,视频或数据盘(例如数字通用盘(DVD))的基板。 盘元件基本上水平地并且彼此同轴地保持,使得在盘元件之间形成间隙,然后在间隙的内部区域中,在圆周方向上以单独的股线的形式将液体粘合剂施加在 光盘元件的面对面。 盘片元件相互靠在一起,并随着上盘元件的重力和粘合剂的毛细作用力一起顺序旋转而快速旋转,与后者的离心力相关联 快速旋转,以在盘元件之间形成预定厚度的均匀且无气泡的粘合剂层。
