发明名称 Method and device for producing cases with rounded corners
摘要 The invention pertains to a method and apparatus for producing cases with rounded corners. According to this method, the corner edge (10) that protrudes in the region of a rounded corner (9) is initially uprighted and turned over and subsequently pressed on the cover boards (7a, b, c) together with the turning-over and pressing-on of the lateral edge (11a) of an adjacent lateral border, in the same station (1). The apparatus comprises at least one rounded corner tool (3) that is arranged in the same station (1) in the which the lateral edges (11a, b) of opposed lateral borders that lie parallel to one another are uprighted, turned over, and pressed on the cover. The rounded corner tool (3) can be moved (b) toward the center of the case and out of the effective range of the lateral turn-in device (24) immediately before the turning-over and pressing-on movement (c, d) of the lateral turn-in device (24).
