Cutting arrangement having a tip-to-tip blade arrangement

A method for longitudinally cutting or dividing material, comprising the following steps:

• providing a cutting assembly comprising two blades that are disposed across from one another and that during a cutting process cooperate with one another, wherein each of said blades is embodied as a circular blade having a sharp cutting edge and supported by an adjusting or placement mechanism;
• cutting said material, wherein during said cutting said circular blades are positioned by means of said adjusting or placement mechanisms in such a way that said cutting edges overlap one another to form an overlap zone and a center of said overlap zone coincides with a middle of the material that is to be cut or divided;
• providing an adaptive control assembly configured for compensating load fluctuations, said adaptive control assembly comprising separate, individual drive motors for driving each of the two blades;
• means for constant side load force control;
• and blade diameter sensors for sensing automatically a respective diameter of said blades;
• monitoring of a blade side force and adjusting in real time side load pressures in response to changes in web speed, web tension, and blade condition by said means for constant side load force control;
• and
• automatically calculating a zero point of a cut, automatically determining a blade speed for said blades that is suitable for said material being cut, and automatically setting the overlap zone by said blade diameter sensors.
