摘要： A razor blade is provided comprising a substrate comprising a first portion and a second portion. The first portion may comprise first and second generally parallel outer surfaces. The second portion may comprise first and second sections separated by a split line. The first section may comprise a first facet extending directly from the first outer surface of the first portion and an end facet extending directly from the first facet. The second section may comprise an end facet. The end facets of the first and second sections may converge at a tip to define a cutting edge. The split line may pass through the tip and is generally parallel with and extends between the first and second outer surfaces of the first portion.

摘要： A razor blade having a substrate with a cutting edge being defined by a sharpened tip is provided where the substrate is comprised of a molybdenum (Mo) content of about 1.6% to about 5% by weight of composition and thicknesses of 1.60-1.75 μm and 9.25-10.00 μm measured at a distance of 4 and 40 μm from the blade tip, respectively. This thickness ratio is between 0.165-0.185. The substrate thickness is about 2.70-3.00 μm at 8 μm from the blade tip, about 4.44-5.00 μm at 16 μm from the blade tip with a thickness ratio measured at 4 μm and 8 μm between 0.56-0.62, and a thickness ratio measured at 4 μm and 16 μm between 0.32-0.40. The edge shape may be defined by equation w=adn with “a” between 0.50-0.62 and “n” between 0.76-0.80. A semi-included angle less than 7° is measured at a distance of 40 μm or greater from the blade tip. This substrate will have substantially no cracks.

摘要： A razor blade having a substrate with a cutting edge being defined by a sharpened tip. The substrate has thicknesses of 1.60-1.75 micrometers and 9.25-10.00 micrometers measured at a distance of four and forty micrometers from the blade tip, respectively. A ratio of the thickness measured at four micrometers to the thickness measured at forty micrometers is between 0.165-0.185. The substrate thickness is about 2.70-3.00 micrometers at eight micrometers from the blade tip, about 4.44-5.00 micrometers at sixteen micrometers from the blade tip with a thickness ratio measured at four micrometers and eight micrometers between 0.56-0.62, and a thickness ratio measured at four micrometers and sixteen micrometers between 0.32-0.40. The blade edge shape is defined by equation w=adn where “a” is between 0.50-0.62 and “n” is between 0.76-0.80. An included angle of less than 7° is measured at a distance of forty micrometers or greater from the blade tip. A nitrided substrate may also be provided.

摘要： The invention discloses a novel application of standard printed circuit board (PCB) assembly modules, electronic assembly, and/or semiconductor assembly equipment for the assembly of consumer products, such as razor cartridges. In addition, nozzles of the pick/place component placement machine of the present invention may be desirably adapted to operate on type of razor cartridge component (e.g., blade, lubricating strip) disposed on a pallet. The adapted nozzle may include adaptors which may have an elongated portion, an angled portion, a tapered portion, a gripper portion, a curved portion, a rounded portion, a pointed tip, a stamper, a marker, a printer, a guide portion, a spring portion, a moveable leg, or any combination thereof, for operating on a razor cartridge component.

摘要： A razor cartridge is provided comprising: a housing and a blade assembly mounted to the housing. The blade assembly may comprise at least one razor blade defined by a substrate comprising a first portion and a second portion. The first portion may comprise first and second outer surfaces. The second portion may comprise first and second sections separated by a split line. The first section may comprise a first facet and an end facet. The second section may comprise an end facet. The end facets of the first and second sections may converge at a tip to define a cutting edge. A shoulder may be positioned between the first facet and the end facet of the first section and define a skin-contacting surface.

摘要： This invention relates to a novel application of hard, low friction aluminum magnesium boride (AlMgB14, also known as BAM) based ceramic coatings to surfaces of razor components and in particular to blade edges of razor blades. On razor blade edges, these coatings may elevate blade performance, while also simplifying the manufacturing process.
