Abstract
A method for the cutting of material is to be cut by means of a cutting machine which includes a horizontal cutting support for material to be cut, a horizontal cutting blade displaceable in height above the cutting support for cutting the material to be cut supported on the cutting support, a drive motor for the height displacement of the cutting blade, a manual control for the drive motor, and a protection device safeguarding the working region of the cutting machine. The method has the steps of: lowering the cutting blade, when the protection device is not interrupted, by actuating the manual control; and stopping the cutting blade which is being lowered when the protection device is interrupted. Immediately after stopping the cutting blade which is being lowered, the drive motor is operated to reverse the cutting blade under safety monitoring into a nondangerous upper safety location.
