Patent ID: 7757594

Claim:
A longitudinal cutting machine, comprising: a first longitudinal guide, an upper blade that is held and is displaceable on said first longitudinal guide; a second longitudinal guide; a lower blade that is associated with said upper blade, wherein said lower blade is held on and is displaceable along said second longitudinal guide; a displacement device associated with said lower blade, wherein said displacement device is provided with an extendable driving rod that bridges a gap to that said first longitudinal guide of said upper blade, and wherein said driving rod, when extended, acts on said upper blade such that said displacement device is adapted to displace said upper blade and said lower blade together; wherein said driving rod has a guide mechanism projecting laterally therefrom, wherein said guide mechanism in the extended position of the driving rod is adapted to act on said first longitudinal guide of said upper blade such that the driving rod held on the displacement device of said lower blade is centered and stabilized by action of the driving rod on said upper blade and simultaneously by action of said guide mechanism on said first longitudinal guide of said upper blade, thereby forming a rigid system for displacement of said lower blade and said upper blade, respectively.
