Abstract:
1. 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; and 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, matching rotational surface speeds of said blade; and setting differential speeds for said blades via said individual drive motors.
