Abstract
A bladeset for a hair clipper includes at least one stationary blade having a plurality of stationary blade teeth, and at least one moving blade having a plurality of moving blade teeth and being configured for laterally reciprocating relative to the at least one stationary blade for cutting hair therebetween, the moving blade having a set of long teeth configured for cutting hair across a width of said moving blade, and a set of short teeth configured for cutting hair across said moving blade width when a clipper feed rate exceeds a given speed.

A bladeset for a hair clipper, comprising:
- at least one stationary blade having a plurality of stationary blade teeth;
- and
- at least one moving blade having a plurality of moving blade teeth and being configured for laterally reciprocating relative to said at least one stationary blade for cutting hair therebetween, said moving blade teeth including a plurality of long teeth alternately arranged with a plurality of short teeth, said plurality of long teeth and said plurality of short teeth each being configured to cut across at least an entire width of said moving blade at relatively high hair feed rates;
- and
- said stationary blade teeth are each separated by a stationary blade teeth cavity and wherein a horizontally oriented first cutting zone is formed in an area where said short teeth and said stationary blade teeth cavities overlap, and a second horizontally oriented cutting zone is formed in an area where said long teeth and said stationary blade teeth cavities overlap, said first and second cutting zones extending along the entire width of said moving blade, and said cutting zones overlapping each other, so that said first cutting zone is within said second cutting zone, such that said short teeth and said long teeth cut hair in the same area of the bladeset at said high hair feed rates.
A bladeset for a hair clipper, comprising:
- at least one stationary blade having a plurality of stationary blade teeth each having a substantially rounded tip;
- and
- at least one moving blade having a plurality of moving blade teeth and being configured for laterally reciprocating relative to said at least one stationary blade for cutting hair therebetween, said moving blade teeth including a plurality of long teeth alternately arranged with a plurality of short teeth, each of said long and short teeth having a substantially flat moving blade tip and a continuous square cross-section from a root to said moving blade tip, said moving blade has at least twice as many teeth as said stationary blade;
- where said stationary blade teeth are each separated by a stationary blade teeth cavity, and wherein a first cutting zone is formed in an area where said short teeth and said stationary blade teeth cavities overlap, and a second cutting zone is formed in an area where said long teeth and said stationary blade teeth cavities overlap, said first and second cutting zones being parallel to each other and extending along a width of said moving blade, said first zone being included in said second zone;
- wherein said long teeth are configured for cutting hair across at least an entire width of said moving blade, and said short teeth are configured for cutting hair across at least an entire moving blade width when hair is fed to said bladeset at relatively high feed rates.
