Hair-cutting apparatus having a toothed cutting device, and toothed cutting device for a hair-cutting apparatus

A toothed cutting device for an apparatus for cutting hairs, which toothed cutting device comprises a first toothed cutter with a first cutter-tooth row, which extends in a tooth row direction and comprises a plurality of cutter teeth, and a second toothed cutter with a second cutter-tooth row, which also extends in the tooth row direction and comprises a plurality of cutter teeth, in which:

• said first toothed cutter is reciprocatingly drivable relative to said second toothed cutter in accordance with a given stroke H, by a reciprocating bridge driven by said drive mechanism of the apparatus,
• both toothed cutters lie against one another in the area of their cutter-tooth rows,
• both toothed cutters have two supporting limbs each in their areas which, in directions transverse to the tooth row direction, are remote from the cutter tooth rows, which supporting limbs face one another pairwise and each are spaced apart in the tooth row direction,
• one of the two toothed cutters carries an intermediate element of a low-friction material, which intermediate element comprises at least one intermediate element portion interposed between said two facing supporting limbs, via which portion at least one supporting limb of this one toothed cutter acts upon at least one supporting limb of the other toothed cutter and has a given dimension in the tooth row direction,
• wherein the at least one intermediate element portion of the intermediate element carried by one of the two toothed cutters has a smaller dimension in the toothed cutter direction than the at least one supporting limb of the other one of the two toothed cutters, which last-mentioned supporting limb faces the at least one intermediate element portion.
