   "Dual PROFI" by LVB - double action system drive mechanism completely in oilbath

General features: It is a simple and efficient system (euro patent) completely in oilbath, which makes possible to drive two cutting knives in horizontal opposed movement. The force of inertia of each one of the knives is mutually balanced even though their relative stroke is bigger than the one of any single knife system. This brings a drastic reduction of the vibrations and an important increase of work pace.

Advantages of the system:

The system brings a substantial working comfort to the operator, due to a drastic reduction of vibrations. Less effort and more efficiency.

Wears and derangement resulting of vibrations decrease, with consequent saving in terms of spare parts and deadlocks of the machine. The investment cost will be amortised over a short time.

Through the important augmentation of the stroke it is possible to obtain a considerable increase of the machine productivity, for it is possible to work with a lower motor's rotation speed and higher feed rate.
