Abstract: A method of joining a razor blade to a blade support to form a razor blade assembly, the method including: directing a laser beam having an adjustable power output at an upper surface of the razor blade; and while advancing the laser beam along the razor blade: a) applying the laser beam at a first power output to the razor blade; b) reducing the first power output of the laser beam to a second power output; and c) applying the laser beam at the second power output to the razor to form a weld area joining the razor blade to the blade support. The weld area may be elongated and may include (i) a ratio of depth:width that is greater than about 2:1, and/or (ii) a ratio of length:width that is greater than about 5:1.

Abstract: A razor blade assembly including: a razor blade; a blade support; and one or more weld areas joining the razor blade to the blade support, each weld area having a length and a width, in which the width is about 0.05 mm to about 0.15 mm. Also provided is a razor blade assembly including: a razor blade; a blade support; and one or more weld areas joining the razor blade to the blade support, each weld area including a depth and a width, in which the depth is about 0.10 mm to about 0.20 mm.

Abstract: Cutting members for razors are provided that have a blade portion and a base portion, the blade portion having a cutting edge region terminated at a free end thereof and an opposing non-cutting edge region, the blade portion being bent relative to the base portion in a bent portion spaced from the cutting edge region and adjacent to the non-cutting edge region, wherein the bent portion extends about 108 degrees to about 115 degrees from the base portion, the bent portion having a radius of about 0.30 mm to about 0.45 mm, at least part of the cutting member having a hardness of about hardness of about 540 HV to about 750 HV, and a thickness of the bent portion is less than the average thickness of the cutting member.

Abstract: Cutting members for razors are provided that have been subjected to a localized heat-treating process, e.g., application of laser energy. In some cases, the cutting members include a bent portion, and the localized heat-treating process is used to enhance ductility and thereby facilitate formation of the bent portion.

Abstract: This invention relates to methods and systems for attaching components to strips of material to form assemblies, e.g., a system for fastening pre-sharpened razor blades to individual support strips on a continuous band of material, such as a metal, to form discrete blade assemblies.
