Cutting device for trimming printed paper packages in a packaging machine

摘要

A cutting device for trimming printed paper packages in a packaging machine. A cutting unit includes an upper part and a lower part which are movable relative to each other when a paper package passes between them. The package originates from paper material on a reel and is formed into a flat tube with glued edges with an unprinted neutral strip. One of the parts of the cutting unit carries two blades spaced apart by a distance equal to the width of the neutral strip and interacts with two counter blades on the other part. An elastic presser is positioned on one of the parts of the cutting unit to hold the package while the neutral strip is being cut by the blades. Spacers are provided so that the distance between the blades can be varied to match the width of the neutral strip.
