ABSTRACT:
A panel cutting machine having a table with an endless belt conveyor and a pair of rollers mounted thereon for advancing a fabric to be cut to a desired length across and beyond a line of cut of a cross-cutter and along the table toward a sensor located a preselected distance from the line of cut. The sensor, which may be the usual microswitch or a photo-electric sensor switch, responds to the arrival of the leading edge of the fabric to activate a roller revolution counter to count a predetermined number of further revolutions and fractions thereof of one of the rollers, corresponding to a further distance of advance of the leading edge of the fabric beyond the sensor. Upon completion of the count, the counter activates a control circuit to stop the rollers and conveyor and start a cross-cutter to cut the fabric along the cutting line to form a panel of the desired length.
