Only when taking into account a possible change in the parameters the current detected torque value from the calculated setpoint torque for sharp knives deviates, the must then according to a further preferred embodiment at least one knife is pushed forward of the knife drum. It is further preferred if only when this deviation a predetermined Tolerance amount exceeds, a feed movement of the knife is triggered.
  • the cutting force is reached by a sensor for the cutting force detects and causes adjusting means to move the knives, the knives readjust and thus regrinding the knives using the grinding wheel cause.
  • Example 2 There are small foreign objects in the clippings.
  • example 1 The situation mentioned in example 1 is shown by a short increase in cutting force (in the range of 2 seconds) with subsequent cutting force disruption.
  • the knives are partially destroyed by the foreign bodies and are located Foreign matter no longer engages with the grinding wheel.
  • Example 3 There are large foreign objects in the clippings.
  • example 1 The situation mentioned in example 1 is characterized by a rapidly increasing Cutting force disturbed. If the upper threshold is exceeded, the Tobacco cutting machine turned off and a foreign body message by sound or Light signal emitted.
  • Example 4 The tobacco moisture of the clippings is reduced.
  • the situation mentioned in example 1 is proportional to the sinking Cutting force rising tobacco disturbed. This is done by a corresponding Signal to the moisture change of the clippings and advanced the knives depending on the detected torque until that Torque remains constant again. When the knife feed the cutting force cannot stabilize, if the upper threshold is exceeded the Tobacco cutting machine turned off.
