Method for manufacturing barber scissors, and barber scissors

Abstract

The invention relates to a method for manufacturing barber scissors, wherein the scissor blades are pre-shaped from blanks by a predetermined degree of curvature in the direction facing away from the edge. This is followed by a step of welding on a hard metal material in the form of a welding bead on respective mutually facing faces of the scissor blades in order to form the edges, wherein the preliminary curvature of the scissor blades is neutralized owing to the influence of heat during the welding process. Subsequently the welding beads are ground so as to form the edges, and the scissor halves are pre-set and hardened. Then the barber scissors are hard-set in the assembled condition. The invention furthermore relates to barber scissors having such a configuration. Here the edges are present as massive material over the entire thickness of the scissor blades, so that even severally repeated re-grinding or re-setting of the barber scissors is possible without any loss of functionality.

1 . Barber scissors comprising two scissor halves each including a scissor blade, a shank, and a ring and articulatedly coupled with each other in an articulation by means of a lock, and including edges of hard metal on each scissor blade, wherein the edges:
 are formed by welding application of a hard metal and a subsequent grinding step,   are formed as massive elements,   extend over an entire thickness of the scissor blades, and   are provided on mutually facing front faces of the scissor blades.   
   
   
       2 . The barber scissors in accordance with  claim 1 , wherein the insides of the scissor blades and of the edges have a fine-ground surface. 
   
   
       3 . The barber scissors in accordance with  claim 1 , wherein the insides of the scissor blades and of the edges have a matted surface. 
   
   
       4 . The barber scissors in accordance with  claim 1 , wherein the hard metal of the edges is comprised of a cobalt-based alloy. 
   
   
       5 . The barber scissors in accordance with  claim 4 , wherein the cobalt-based alloy comprises 30% of Cr, 12% of W, 2.5% of C and the remainder Co, the cobalt-based alloy having an HRC hardness between 51 and 58.
