Problems solved by technology

[0010] A further disadvantage of the hair clippers described in DE 19909887 A1 is that resharpening the blade by grinding is generally only possible at most once, since the applied hard metal material is removed during processing, and the blade is then formed again from an unsuitable base material

Embodiment Construction

[0034] Such as figure 1 with figure 2 As shown in , the hair clipper 1 comprises two scissor halves 2 and 3 which are pivotally connected to each other by means of a locking pin 4 . The scissors half 2 includes a ring 21 , a handle 22 , a scissors edge 23 and a blade 24 . In addition, a knife edge stop 25 and a finger strut 26 can also be arranged on the ring 21 . The scissors half 3 includes a ring 31 , a handle 32 , a scissors edge 33 and a blade 34 .

[0035] The following will refer to Figures 3A-3C The manufacturing steps of the hair clipper 1 are explained by taking the scissor half 2 as an example, and the manufacturing steps of the scissor half 3 are similar.

[0036] First, the two scissors halves 2, 3 are provided and handled in their known conventional manner. Specifically, at the beginning of the work, while cutting the threads and drilling the threaded holes for the locking pins 4 in the form of bolts on the assembled part, the grinding and polishing of the...

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.

Description

technical field [0001] The present invention relates to a method of manufacturing hair clippers. Background technique [0002] Scissors traditionally consist of two halves hingedly interconnected by a locking pin, and the two scissor halves and their blades are usually formed from stainless steel or a rust resistant steel alloy. However, such scissors present the disadvantage of losing their sharpness in the area of ​​the blade after a relatively short period of use. The technique of applying a hard metal layer in the region of the cutting edge is also known for this purpose. The service life of the scissors can thus be considerably extended and the blades will remain sharper for longer due to the strength of the hard metal. In contrast, however, hard metals are relatively brittle, making the manufacturing steps to assemble the clippers more difficult to perform than scissors with traditional steel alloy blades. Excessive machining and the resulting deformation can create...
