Abstract
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 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 of blade supports. The coil of supports is then fed into a device for severing each support from the coil and registering it with a blade element for attachment thereto.
Claims9
A method of manufacturing a plurality of razor blades each having a cutting edge portion affixed to an elongated support member, including the steps of:
- providing an elongated strip of sheet material, said elongated strip being in the coiled condition and having opposite edge portions;
- forming a plurality of discrete support members between said opposite edge portions at a first work station and rewinding said coiled strip with said support members retained between said opposite edge portions;
- introducing said coiled strip at a second work station having means to feed said strip of material into said second work station;
- employing said feed means to feed said strip of material along a path into said second work station;
- severing each of said support members sequentially from between said opposite edge portions and;
- removing each said support member from said second work station in a direction transverse to the path of said strip feed and transferring each said support member to a third work station for attachment to a cutting edge portion of a razor blade.
