ABSTRACT:
A cutting apparatus for heated stock in the form of metallic bars of finite length, includes a transport device for moving the bars back and forth in longitudinal direction of the bars along a transport path, a heating device upstream of the transport device along the transport path, a cutting device downstream of the transport device along the transport path for cutting the bars to a given bar section length at a cutting position, a stop downstream of the cutting device along the transport path for limiting movement of the bars, a clamping device disposed between the cutting device and the stop along the transport path for holding bars of at least a given minimum remnant length in the cutting position, a device in vicinity of the cutting device for carrying away cut bar sections and end remnants of bars out of the cutting position, a repulsion device in vicinity of the cutting device for moving the bar remnants into the heating device after cutting, a sensor disposed along the transport path for sensing presence and absence of the bars, the sensor having a sensing region disposed at a spacing substantially equal to twice the given bar section length plus the minimum remnant length upstream of the stop, and a control device connected to the sensor for delivering control signals for the further treatment of the bar remnants as a function of the absence and presence of a portion of a bar section in the sensing region of the sensor.
