Power-operated sheep shears - have fixed and rapidly oscillating comb cutters, with latter including undulating cutting edges

摘要

The power shears have fixed and rapidly oscillating comb cutters, the teeth (4) of the latter having undulating cutting edges (5, 6). The undulations reduce the likelihood of clogging and have a depth exceeding the thickness of the hair of the animal concerned. The undulations may be symmetrical and the troughs may be triangular, curved or polygonal. Triangular troughs may have the isosceles form.
