Device for displacing layers of ink on printed material

摘要

At least two oppositely moving rollers (26,28), preferably of a non-deformable material are provided spaced from each other and with their radial outer sides facing one another. The distance between corresponds to the thickness of the printed material (18) passing between the rollers. The rollers can be moved and adjusted across the direction of movement of the printed material. The device can be formed by a base member (1) with groove (24) tapering inwards so that a slit (5) is formed extending in the direction of movement of the material. The cross section of the rollers can taper outwards and be rounded.
