    • A method for manufacturing cardboard corner pieces from at least one cardboard web (1a, 1b, 1c) and two or more coating webs (2a, 2b) consisting of another material. Said method is characterized in that it involves supplying and glueing the cardboard web or webs (1a, 1b, 1c) on top of each other and onto a first coating web (2a) which is broader than said cardboard webs; folding the longitudinal edges of the coating web (2a) until they are folded over the free side of the last cardboard web (1c); glueing a second coating web (2b) having substantially the same width as the cardboard webs over the folded-over portions of the first coating web (2a) and the free side of said last cardboard web (1c); and folding the assembly thereby obtained along its length to form a substantially right-angled corner piece (7). A device for implementing the method, and the product thereby obtained, are also described.
    • 一种由至少一个纸板织物(1a,1b,1c)和由另一种材料组成的两个或多个涂覆织物(2a,2b)制造纸板角件的方法。 所述方法的特征在于它包括将纸板幅(1a,1b,1c)彼此顶部供给并粘合到宽于所述纸板幅的第一涂布幅(2a)上; 折叠所述涂​​布网(2a)的纵向边缘直到它们折叠在最后的纸板网(1c)的自由侧上; 在第一涂布网(2a)的折叠部分和所述最后纸板网(1c)的自由侧上粘合具有与纸板网基本相同宽度的第二涂布网(2b); 并沿其长度折叠由此获得的组件以形成基本上直角的角件(7)。 还描述了用于实施该方法的装置以及由此获得的产品。
