ABSTRACT:
Cigarettes are perforated by being rolled along a row of pins which are excited, for example by being vibrated. Vibration may be towards and away from the cigarettes so that the pins penetrate as a result of the vibration; the depth of penetration may be varied to control the size of the perforations. Alternatively the vibration may be in a direction transverse to the axes of the pins. In either case the pins may be mounted on a flexible member having a resonant frequency equal to the frequency of vibration. The vibratorary drive may be an electro magnetic device or a piexoelectric crystal. An alternative form of excitation of the pins involves passing compressed air through the pins and into the cigarettes, the pins being tubular for that purpose.
