<p>The underside of the cutter (15) has a straight, L- or U-shaped part with blades. It moves up and down on rockers or vertical guides. The cutter oscillates or rocks by at least one vibrator (20), and is connected to the appliance on elastic holder points (7,8) in the form of rubber pads or sleeves or rubber and metal connections. The oscillations produced by the vibrator are directed towards the transverse blade (18). The vibrator is driven mechanically or electrically or by pressure medium.</p> |
