Abstract
A piercing device for piercing holes in cigarettes or similar smoking commodities, in which a laser beam emitted by a continuous laser source is directed, by a mobile reflecting and focusing unit, mounted in a rotary manner around an axis a fixed reflecting member is arranged on the axis and the beam is reflected on to the cigarettes for piercing, while the latter turn round their own axis and travel crosswise in relation to the axis of the beam. The mobile unit receives the laser beam in a direction coaxial with the axis and diverts it first outwards and then towards the latter. The focused beam is derived on to the cigarettes by a ring of mirrors with which the reflecting member is provided.
