Abstract
A cigar, cigarette or similar smoking product is perforated immediately prior to wrapping by a set of needles mounted in a block arranged to be moved onto the cigar or cigarette to be perforated. The needles are guided and protected by an apertured stripper plate which is mounted on the block for movement in the direction of the needles. The stripper plate is provided with spring loading between itself and the block so as to urge the stripper plate away from the block.
