Abstract
A cigarette perforating device for filter cigarettes in which the cigarettes are rolled between a drum and a rolling plate carrying perforator pins. The rolling plate is mounted on a pivot arm which is held in the operative position by an adjustable permanent magnet latch so that when a predetermined increase in pressure occurs in the device, due to a jam, the rolling plate can move away from the drum. This action also operates a switch controlling an electromagnetic catch retaining a conveyor carrying cigarettes away from the perforator so that damaged cigarettes are then dropped to waste.
