Patents Assigned to TIM Tuttlinger-Instrumenten-Manufaktur GmbH
  • Publication number: 20080155836
    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.

  • Patent number: 7322262
    Abstract: The invention relates to a method for manufacturing barber scissors (1), wherein the scissor blades (23, 33) 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 (23, 33) in order to form the edges (24, 34), wherein the preliminary curvature of the scissor blades (23, 33) is neutralized owing to the influence of heat during the welding process. Subsequently the welding beads are ground so as to form the edges (24, 34), and the scissor halves (2, 3) are pre-set and hardened. Then the barber scissors (1) are hard-set in the assembled condition. The invention furthermore relates to barber scissors (1) having such a configuration.
