Provided is a method of producing an outer blade for a hair cutting device from a material including bars that each have a shape of a rectangular stick and are arranged at predetermined intervals. The material is placed on a base. Next, a first tool having a leading end that has a gradually increasing width in a direction away from the material is used to press at least one part of each of the bars in a direction from a counter base-side first face of each of the bars toward a base-side second face of each of the bars. An edge of the first face of each of the bars is caused to project widthwise and to move toward the second face to be farther from an intermediate part of the first face.

The present disclosure relates to a blade set (26) for a hair cutting appliance (10), said blade set (26) being arranged to be moved through hair in a moving direction (38) to cut hair, said blade set (26) comprising a stationary blade (42) comprising a support insert (70) and a metal component (68), wherein the metal component (68) and the support insert (70) are force-fitted to one another, wherein the metal component (68) is at least sectionally deformed to define at least one toothed leading edge (32, 34) having double-walled stationary blade teeth (44), wherein the metal component (68) forms a first wall (100) that is arranged to serve as a skin-facing wall when in operation, and a second wall (102) that is facing away from the first wall (100), and wherein a guide slot (60) for a movable blade (62) is defined between inwardly facing inner surfaces of the metal component (68) and the support insert (70), and a movable blade comprising a plurality of movable blade teeth (64), wherein the movable blade (62) is movably arranged between the metal component (68) and the support insert (70) in the guide slot (60), and wherein the movable blade (62) is, in the mounted state, preloaded and movably arranged in the guide slot (60) between the metal component (68) and the support insert (70). The disclosure further relates to a corresponding manufacturing method.

The present invention relates to electric appliances for personal care, in particular electric shavers, comprising a magnetic linear drive unit having first and second drive components supported for linear displacement relative to each other by a spring device and adapted to magnetically interact with each other. Said spring device includes a ring element made in one piece from plastic including at least one pair of leaf springs and a pair of cross-bars extending crosswise to said leaf springs and connecting said leaf springs to each other.

A stationary blade for a blade set in a hair cutting appliance and method of manufacturing the stationary blade. The stationary blade comprising a first wall portion arranged as a skin facing wall in operation, a second wall portion at least partially offset from the first wall portion. The first and second wall portions defining a guide slot therebetween, arranged to receive a movable cutter blade. At least one toothed leading edge comprising a plurality of teeth jointly formed by the first wall portion and the second wall portion. The stationary blade being an integrally formed metal-plastic composite blade. The first wall portion being at least partially made from a metal material. The second wall portion being at least partially made from a plastic material. The first and second wall portions being arranged to receive the movable cutter blade in the guide slot in a defined mating manner.

A method of manufacturing a blade set (20) of a hair cutting appliance (10) includes forming a stationary blade (22). The stationary blade (22) comprises a first wall portion (100) arranged to serve as a skin facing wall when in operation, a second wall portion (102) at least partially offset from the first wall portion (100), such that the first wall portion (100) and the second wall portion (102) define therebetween a guide slot (96) arranged to receive a movable cutter blade (24), an intermediate wall portion (44) arranged between the first wall portion (100) and the second wall portion (102), and at least one toothed leading edge (30) jointly formed by the first wall portion (100) and the second wall portion (102). The at least one toothed leading edge (30) comprises a plurality of teeth (36), wherein the first wall portion (100) and the second wall portion (102) are connected at a frontal end of the at least one leading edge (30), thereby forming tips (86) of the teeth (36).

A cutting appliance and a blade set that includes a cutter and a stationary blade. The stationary blade has a guide slot. A cutter is movably arranged within the guide slot. The cutter includes, at a side thereof facing away from a skin facing wall of the stationary blade, an elevated spacing arrangement associated with a toothed leading edge of the cutter, and being configured for spacing a substantially flat bottom surface of the at toothed leading edge of the cutter away from the skin facing wall.

A stationary blade for a hair cutting appliance and a method of forming the stationary blade includes providing tooth components obtained from metal material, where the tooth components are arranged in a substantially flat fashion and are at least partially tapered towards a tip end. The method further includes arranging the tooth components next to each other to form a series of spaced apart teeth, where neighboring tooth components are arranged at a distance from one another; providing a blade base acting as a support receptacle, arranged to receive the tooth components; and interconnecting the tooth components and the blade base in a direct or mediate fashion, thereby forming teeth of the stationary blade.

The present disclosure relates to a hair cutting appliance (10), a blade set (20) for a hair cutting appliance (10), and to an integrally formed metal-plastic composite stationary blade (22) for said blade set (20). Said stationary blade (22) may comprise a first wall portion (58) arranged to serve as a skin facing wall when in operation, a second wall portion (60) at least partially offset from the first wall portion (58), such that the first wall portion (58) and the second wall portion (60) define therebetween an inner guide slot (116) arranged to receive a moveable cutter blade (24), at least one toothed leading edge (30) jointly formed by the first wall portion (58) and the second wall portion (60), and a plastic component (114) comprising at least one mounting element (36), wherein the at least one toothed leading edge (30) comprises a plurality of teeth (90), wherein the first wall portion (58) and the second wall portion (60) are integrally made from a metal component (56), particularly from a sheet metal component (56), wherein the first wall portion (58) and the second wall portion (60) mutually define an inner metal shell of the stationary blade (22), and wherein the plastic component (114) is molded to the second wall portion (60).
