Abstract:
The device for satinizing and embossing packaging foils comprises at least two embossing rollers that are each provided with a toothing consisting of individual teeth, the pyramidal teeth having an essentially rectangular horizontal projection, and the sides of the teeth being essentially parallel and perpendicular, respectively, to the longitudinal axis of the embossing roller. In contrast to the prior art, the opening angle (α) between the radially aligned adjacent tooth flanks is smaller than the opening angle (β) between the axially aligned adjacent tooth flanks, and the tooth height in the radial direction, measured from the tooth tip to the tooth bottom, is greater than the tooth height in the axial direction measured from the tooth tip to the tooth bottom. This dimensioning and arrangement of the teeth provides an improved gearing with a reduced specific pressure as well as an improved processing of the paper part of the foil that results in its better folding, curling, and tubing behavior.
