ABSTRACT:
A hair trimming head for slow rate hair trimming and thinning having a stationary blade with cutting teeth and a movable blade with cutting teeth, the blades being mounted in effective cutting relation with the teeth of the movable blade projecting beyond the ends of the teeth on the stationary blade, whereby hair first engages the teeth of the movable blade and is agitated and fed in controlled manner between the movable teeth into cutting engagement with the teeth of the stationary blade.
The relative longitudinal positioning of the two blades is non-critical, it being necessary only to position the blades such that the effective cutting lengths of the teeth on the stationary blade lie within the limits of the effective cutting lengths of the teeth of the movable blade. The effective cutting length of the teeth of the stationary blade is of the order of about one or two times the diameter of human hair, thereby providing control over the amount of hair cut so overcutting and uneveness are avoided.
