<p>A cutter reciprocatingly drivable in opposite directions and adapted to co-operate with the shear foil of a dry-shaving apparatus comprises support means and a plurality of pairs of arcuate cutter lamellae mounted on such support means. The distance between the two cutter lamellae of each pair is smaller than the distance between either cutter lamella of such pair and the adjacent cutter lamella of the adjacent pair at the location of the top of the cutter lamellae. The two cutter lamellae of each pair respectively include angular portions oriented towards each other at the location of the top of the cutter lamellae, the angular portions of the two cutter lamellae of each pair being urged against each other under pre-load. The cutter lamellae of each pair are elastically movable in both directions of reciprocation of the cutter, the leading cutter lamella of each pair, viewed in the direction of reciprocation of the cutter, acting as an elastic hair-pulling blade and the trailing cutter lamella of such pair acting as a rigid cutting blade.</p> |
