  • Patent number: 11213963
    Abstract: 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).

  • Patent number: 9126359
    Abstract: A method of producing a device comprises at least one displaceable operating member, wherein a foil (2) is placed into a mold and at least one polymer is injected into the mold to form a housing wall (3) adhering to the foil (2). The displaceable operating member comprises at least a flexible part of the foil (2) extending over a hole (5) in the housing wall (3). The foil is inserted into the mold, after which said polymer is injected into the mold to form the housing wall (3) with the hole and to form a support element (6) located in the hole (5). A gap (7) is provided between the support element (6) and the housing wall (3). The support element (6) is, at least at an outer area (9) near the gap (7), adhered to the foil (2) with a reduced adhesion force compared to an adhesion force between the housing wall (3) and the foil (2). After removing the device from the mold, the support element (6) and the flexible part of the foil (2) are mutually disconnected at a location of said reduced adhesion force.
