Abstract
A blade set assembly for a hair cutting appliance includes a stationary blade and a movable blade. The movable and stationary blades are arranged one on top the other and movable relative to each other. A guide unit is formed between the movable blade and the stationary blade, where the blades engage each other. The guide unit includes longitudinally spaced, laterally extending guideways, each defined between a stationary blade guide surface and a movable blade guide surface that overlap each other. Rolling elements are arranged at the guideways between the guide surfaces. The guide surfaces have a height extension greater than a radius of the rolling elements such that the guide surfaces overlap in a vertical direction. The guide surfaces provide for coupling in a longitudinal direction between the blades such that the guide unit provides for a set longitudinal distance for any force applied in the longitudinal direction.
