CA 2236890

A razor blade construction is manufactured of a thin element of blade stock forming the cutting edge portion which is welded or otherwise attached to a more rigid support member. A plurality of support members are produced from a coil (20) of flat sheet material by a cutting and forming process, each of the supports being retained at its edge to an adjacent support to provide a coil (20) of blade supports. The coil of supports is then fed into a device (26) for severing each support from the coil and registering it with a blade element for attachment thereto.

Une structure de lame de rasoir est constituée d'un élément mince de matière pour lame formant la partie marginale tranchante qui est soudée ou fixée selon un autre mode à un élément de support plus rigide. Une pluralité d'éléments de support sont produits à partir d'une couronne (20) de tôle plane à l'aide d'un processus de coupe et de formage, chacun des supports étant retenu, au niveau de son bord, sur un support adjacent en vue de constituer une couronne (20) de supports de lame. Cette dernière est ensuite acheminée dans un dispositif (26) destiné à séparer chaque support de la couronne et à l'aligner avec un élément lame pour l'y fixer.
