METHOD OF FOLDING METAL BLANK MADE OF HIGH-STRENGHT MATERIAL WITHOUT CRACKS

A method of manufacturing a component from a high-strength blank metal strip or sheet (MS) having a tensile strength of at least 850 MPa. The method comprises reducing the thickness (T) of the strip or sheet (MS) in a folding section (FS) so that a shaped section (SS) having a predetermined shape is obtained in at least a part of the folding section (FS). The strip or sheet (MS) is then folded along the shaped section (SS), so that a surface of a first section (1S) becomes arranged adjacent and parallel to a surface a the second section (2S) of the metal strip (MS). Finally, the first and second sections (1S,2S) are joined, so that the strip or sheet (MS) remains folded. With this method, it is possible to use high-strength steel, e.g. AISI 301 stainless steel, and still fold a thin strip or sheet (MS) without undesired cracks in the folding section. For example, the invention is applicable for manufacturing of plate-shaped hair-pulling elements (HPE) for a cutting unit (CU) of a shaving apparatus.

SUCTION ATTACHMENTS FOR SURGICAL HAIR CLIPPERS AND METHODS OF USING SUCH SUCTION ATTACHMENTS

A surgical hair clipper assembly includes a clipper body and a blade assembly connected to the clipper body. The blade assembly includes a moveable blade configured to reciprocate to remove hair from a skin area and a blade housing that houses the moveable blade. The blade housing has a guide surface that faces the skin area during a hair removal process. A suction attachment includes a clipper attachment connected to the clipper body and a nozzle structure connected to the clipper attachment and extending distally to an end. The end is located no more than about ten millimeters proximal of a plane defined by the guide surface.

OUTER BLADE FOR HAIR CUTTING DEVICE AND HAIR CUTTING DEVICE

An outer blade for a hair cutting device, the outer blade being mounted to an end of a main body of the hair cutting device, includes bars that each have a shape of a rectangular stick and are arranged at predetermined intervals. The outer blade also includes, at a skin-surface-contact-side first face of each of the bars, an agent holding part configured to hold an agent that is a substance having a predetermined effect on a skin surface, the agent holding part being a surrounded recess heading from the skin-surface-contact-side first face of the bar toward an inner-blade-side second face of the bar. Thus, the agent such as foam or gel can be held by the agent holding part at the skin-surface-side face of the outer blade, and friction can be reduced between the outer blade and the skin surface by the agent held by the agent holding part.

METHOD OF PRODUCING OUTER BLADE FOR HAIR CUTTING DEVICE, OUTER BLADE FOR HAIR CUTTING DEVICE AND HAIR CUTTING DEVICE

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.

BEARD TRIMMER WITH ONE OR MORE ROTARY HEADS HAVING A FIXED BLADE WITH A PARTICULAR SHAPE
20180222066 · 2018-08-09 · ·

The present invention relates to a beard trimmer having one or more rotary heads (1), said rotary cutting heads having a moving blade (2) and a fixed blade (3), each head being surrounded by a crown-shaped comb (4), said comb being adjustable in height in order to adjust, in use, the distance between said blades and the skin, and thereby to adapt the cutting of the beard to the desired length, characterized in that the trimmer comprises a fixed bade having a shape characterized by: a tooth length L3 of 1 to 3 mm, preferably 1.5 to 2 mm; an opening angle between the teeth of 20 to 30?, preferably 22 to 28?, and more preferably 24 and 27?; a tooth width L2, at the end of the teeth, of 0.3 to 1 mm, preferably 0.4 to 0.9 mm.

Carrier for a shaving device, comprising pairs of a cutting element and a hair lifting element

A carrier is adapted for use in a shaving device and includes at least one pair (15) of a cutting element (8) and a hair lifting element (14). At least one of the elements (8, 14) of the pair (15) has a bent shape, wherein the bent element (8, 14) is provided with at least two bending lines (17, 18). The bent shape of the at least one of the elements (8, 14) is such that in a functional arrangement of the elements (8, 14) with respect to each other, edge portions (11, 16) of the elements (8, 14) are located at a distance with respect to each other. Thus, a space (22) is present between the elements (8, 14) at the side of their edge portions (11, 16), which can be used for receiving cut-off hair stubbles which might otherwise hinder a movement of the hair lifting element (14).
