  • Patent number: 10384359
    Abstract: A shaving head is provided that includes one or more cutting blades and actively driveable skin stretching device arranged behind said cutting blade. The actively driveable skin stretching device operates to reduce the possibility of causing nicks and cuts or skin irritation during a shaving operation. The shaving head provides a pivot axis between the shaving head and a handle that is either attached or attachable to the shaving head. The pivot axis is arranged to be essentially parallel to the cutting blade. By providing the pivot axis, the force ratio between a force applied to the actively driveable skin stretching device and forces applied to other parts of the shaving head may be kept constant for different angles of the handle. This improves the functioning of the actively driveable skin stretching device.

  • Patent number: 8397604
    Abstract: A method of manufacturing a cutting member (6) of a shaver (1) includes the steps of providing a plate-shaped carrier (10), cutting at least one cutting element (9a, 9b) free from the carrier except for a residual connection between a base (15, 23) of the cutting element and the carrier, and bending the cutting element relative to the carrier. The steps of cutting free and bending are performed simultaneously using a tool (11) having a combined punching and bending effect. By using such a tool, the action of cutting free is obtained by a tearing process which does not lead to a free space and a loss of material between the cutting element (9a, 9b) and the carrier (10). As a result, the strength of the carrier is not reduced by such a free space or loss of material.

  • Patent number: 8056238
    Abstract: The invention relates to a shaving head (5) comprising at least two bladeshaped cutting members (7, 7?, 7?) each having a straight cutting edge (9, 9?, 9?) extending parallel to a longitudinal direction (Y) of the shaving head. Each cutting member is supported in a cartridge (11) of the shaving head by means of a supporting member (17) which supports the respective cutting member in a supported area (23) on the respective cutting member. Said supported area extends over a predetermined distance (D) perpendicular to the longitudinal direction. Each supporting member has a first portion (25) in contact with the supported area at a location remote from the cutting edge of the respective cutting member and a second portion (27) in contact with the supported area at a location near the cutting edge of the respective cutting member. The first portion has a basic cross-sectional area, seen perpendicularly to the longitudinal direction, and the second portion has a reduced cross-sectional area.

  • Publication number: 20070089297
    Abstract: The invention is directed to a shaving head (8) comprising at least one cutting blade (10, 12) and actively driveable skin stretching means (14) arranged behind said cutting blade (10, 12) relative to a cutting direction (16) of said cutting blade (10, 12). The actively driveable skin stretching means (14) are provided to reduce the possibility that ni cks and cuts or irritations of the skip to be shaved are created during the shaving operation. In accordance with the invention the shaving head (8) comprises means (18) for providing a pivot axis (20) between the shaving head (8) and a handie (22) attached or attachable to said shaving head (8), said pivot axis (20) being arranged at least essentially parallel to said cutting blade (10, 12). By providing the pivot axis (20) the for ratio between a force applied to the actively driveable skin stretching means (14) and forces applied to other parts of the shaving head (8) may be kept constant for different angles of the handle.
