METHOD FOR CONTINUOUS CONTROL OF PRODUCTION OF MACHINES FOR APPLYING CONCEALED MARKS TO PAPER AND DEVICE FOR REALIZATION OF SAID METHOD

摘要

FIELD: equipment for applying concealed marks.;SUBSTANCE: paint mixer 1 is held and guided by stationary means under supports 2 and 3 above paint box, containing paint for applying concealed marks. Paint mixer is driven by changing direction on guiding means meant for it, and its end is dipped in paint. Into aperture 11 detector head is inserted in form of transformer with primary winding, meant to generate zero magnetic field, with adjustable ferrite core, mounted so that zero magnetic field is received for standard magnetic characteristic of printing paint for applying concealed marks, and with secondary winding, quitting balanced state and outputting a signal, if magnetic characteristic of printing paint, into which paint mixer end moves, changes. Output signal is sent to line 4 for transferring signal via sliding contact 6, while grounded pole is connected by means of wire 5 and sliding contact 7.;EFFECT: higher efficiency.;2 cl, 10 dwg
