ABSTRACT:
A sheet cutting apparatus comprising a sheet feeding table, a cutting table and a sheet take-up table. Air lines, filters in the lines and air pumps draw air from the cutting table to collect any dust, etc. The air passes through filters, then to the blowers and from the blowers air is directed outwardly to the sheet feeding table and take-up table which lifts the material from the table. First and second pressure sensors are provided to detect the pressure to the blower and when a pressure difference exceeds a specific level an alarm is sounded to provide a warning. Then the filters can be cleaned.
