摘要： A cutting machine with a cutting support for material to be cut has a vertically movable, horizontal blade bar which bears a blade for cutting the cut material located thereon. A vertically movable, horizontal clamping bar is for pushing down the material to be cut. Two guide plates are arranged adjacent to one another, spaced apart in parallel in the same vertical plane, and in each case said guide plates have an inclined linear slot in which the blade bar is guided, and on the front faces thereof facing one another in each case have a vertical guide on which the clamping bar is guided.

摘要： A cutting machine includes a cutting support for material to be cut, a vertically movable blade bar which bears a blade for cutting the cut material located thereon, a cutting drive for vertically moving the blade bar, a vertically movable clamping bar for pushing down the material to be cut and a pressing drive for vertically moving the clamping bar. The cutting drive and the pressing drive are formed by a single drive which rotates a cam disc to and fro, wherein the blade bar is motion-coupled to the cam disc via a first coupling mechanism which acts on the cam disc eccentrically to the axis of rotation thereof. The clamping bar is motion-coupled to the cam disc via a second coupling mechanism, the one end thereof acting on the outer contour of the cam disc.

摘要： A cutting machine has a cutting support for material to be cut, with a vertically movable blade bar which bears a blade for cutting the cut material located thereon. A cutting drive is for vertically moving the blade bar. A blade depth adjustment is for vertically adjusting the blade bar relative to a vertically movable drive element of the cutting drive. The blade depth adjustment includes a deflection lever which is pivotably mounted about a horizontal axis on the blade bar. The drive element can be articulated thereon at a first radial distance to the horizontal axis. An adjusting mechanism may act on the deflection lever at a second radial distance to the horizontal axis, for rotating and fixing the deflection lever.

摘要： 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.
