METHOD FOR MANUFACTURING OF RAZOR BLADES AND SYSTEM OF AUTOMATIC CONTROL OF RAZOR BLADES PAINTING PROCESS DURING THEIR MANUFACTURING Russian patent published in 2010 - IPC B26B21/54 C23C8/10 

FIELD: technological processes.

SUBSTANCE: invention relates to manufacturing of colour razor blades. Blades colouring is carried out using hardening furnace with zone of oxidation, where oxidant gas is supplied, including air. System of automatic control of colouring process comprises spectrometre, controller and processor. Spectrometre is intended to measure spectrum of reflection from blade steel directly after its colouring. Controller provides for adjustment of process parametre, changing blade colour. Processor identifies value of colour parametre, complying with measured spectrum of reflection, difference between this value of parametre and specified value, and generates control signal from controller of air mass flow in zone of furnace oxidation, if specified difference exceeds established threshold value.

EFFECT: improved quality of produced razor blades.
