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 each cigarette for piercing, the latter being arranged essentially coaxial with the axis and being carried crosswise in relation to it on a rotary drum. The mobile unit receives the laser beam in a direction coaxial with the axis and diverts it first outwards and then inwards to a fixed point on the axis. The focused beam is diverted on to each cigarette by the fixed reflecting member which is provided with two rings of fixed mirrors.
