Abstract
A coating of the cutter parts of an electric dry shaver with a solid lubricant is accomplished by positioning a meshed member over the surface of the cutter parts and then penetrating the meshed member with a solid lubricant preparation. The meshed member is then pulled from the coated cutter parts.
Claims9
A process for coating the cutter parts of an electric dry shaver comprising:
- positioning a meshed member having polyester threads over the surface of the cutter parts;
- penetrating the meshed member with a solid lubricant preparation which includes molybdenumdisulphide in a binder capable of hardening in air;
- and
- pulling off the meshed member.

A process coating the underside of a shear-foil with raised perforated edges comprising:
- positioning a meshed member of polyester threads with a mesh opening of approximately 49 microns and a thickness of approximately 93 microns on the undeside of the shear-foil;
- applying a solid lubricant preparation containing 25% to 45% weight and preferably 40% by weight of molybdenumdisulphide in a binder capable of hardening in air, the solid lubricant preparation having a viscosity of 10 Pascal/Second;
- pressing the solid lubricant preparation through the meshed member;
- pulling off the meshed member;
- and
- appling circulating air at approximately 100.degree. C. to the shear-foil for approximately 20 minutes.

A process for coating the blades of a long-hair cutter comprising:
- positioning a meshed member made up of polyester threads with a mesh opening of approximately 27 microns and a thickness of approximately 70 microns on the upper side of the blades of a long-hair cutter;
- applying a solid lubricant preparation containing 40% by weight of molybdenumdisulphide in a binder capable of hardening in air, the solid lubricant preparation having a viscosity of 10 Pascal/Second;
- pressing the solid lubricant preparation through the meshed member;
- pulling off the meshed member;
- and
- applying circulating air at approximately 100.degree. C. to the long-hair cutter for approximately 20 minutes.
