Abstract:
A device for cutting film-like material as a result of a shearing action performed by a blade and a counterblade provided with respective cutting edges acting in a cutting plane, said blade having a first blade end and a second blade end, said device comprisingan actuating assembly for actuating said blade and adapted to control movement of said blade such that said first blade end moves along a first path and said second blade end moves along a second path, wherein said first path and said second path are substantially parallel to one another, and wherein said blade is thereby moved between a separated position, in which said respective cutting edges define a space through which said film-like material is adapted to advance, and in which said cutting edge of said blade is located at a first distance from said cutting edge of said counterblade at said first blade end, and in which said blade is located at a second distance from said cutting edge of said counterblade at said second blade end, wherein said first distance is greater than said second distance; and a closed position, in which said blade and said counterblade are closed on one another after cutting of said film-like material with a cooperative movement of said cutting edges, wherein said cooperative movement is performed in a gradual way starting from said second blade end toward said first blade end; and a pressure element for applying on said blade a pre-loading toward said counterblade, wherein said pressure element comprises an adjustment member for selectively adjusting said pre-loading.
