折り目付け装置
Document Type and Number:
Japanese Patent JP6616835
Kind Code:
B2
Abstract:
A creasing device is provided that includes a counter-rotating male drum and female drum. The male drum carries a conventional creasing ring with a central rib flanked by shoulders. The female drum comprises a central channel aligned with the creasing rib on the male drum; and a pair of projecting lateral ribs on each side of the central channel that are aligned with the shoulders on the male drum. The lateral ribs press a sheet of the card or paper stock against the shoulders of the creasing ring to better define the edges of the crease and to reduce the tendency of a printed coating on the stock to crack during subsequent folding. The pair of lateral ribs may be provided by a pair of inserts. Alternatively, both ribs and the central channel may be provided by a single insert.
