Manufacturing apparatus of flat type film resistors

Claim 1

A PRINTING APPARATUS FOR MANUFACTURING FLAT TYPE FILM RESISTORS TO PREDETERMINED SPECIFICATIONS, COMPRISING A ROTARY OFFSET PRESS HAVING AN IMPRESSION ROLLER, A BLANKET ROLLER ROLLING AGAINST SAID IMPRESSION ROLLER, A PRINTING ROLLER ROLLING AGAINST SAID BLANKET ROLLER, AND AN INK ROLLER ROLLING AGAINST SAID PRINTING ROLLER, MEANS FOR SUPPLYING A PREDETERMINED PATTERN OF INK TO SAID INK ROLLER FOR TRANSFER TO SAID PRINTING ROLLER AND TO SAID BLANKET ROLLER, MEANS FOR FEEDING SUBSTRATE SHEETS OF A GIVEN SIZE BETWEEN SAID BLANKET ROLLER AND SAID IMPRESSION ROLLER FOR PRINTING SAID PREDETERMINED PATTERN OF INK THEREON TO PRODUCE FLAT TYPE FILM RESISTORS, A PRINTING LOCATION CONTROL DEVICE ATTACHED TO SAID IMPRESSION ROLLER FOR POSITIONING SAID SUBSTRATE SHEETS BETWEEN SAID BLANKET ROLLER AND SAID IMPRESSION ROLLER PRECISELY WITH RESPECT TO THE DIMENSION IN THE DIRECTION OF MOVEMENT OF THE SUBSTRATE SHEET, WHEREBY THE PRINTED RESISTORS HAVE A HIGH DIMENSIONAL STABILITY IN SAID DIRECTION, A PRINTING LOCATION CONTROL DEVICE FOR POSITIONING SAID SUBSTRATE SHEET PRECISELY WITH RESPECT TO THE DIMENSION IN THE TRANSVERSE DIRECTION OF MOVEMENT OF THE SUBSTRATE SHEET, WHEREBY THE PRINTED RESISTORS HAVE A HIGH DIMENSIONAL STABILITY IN SAID DIRECTION, A HEATING FURNACE POSITIONED ADJACENT THE OUTPUT SIDE OF SAID ROTARY OFFSET PRESS AND HAVING A CONVEYOR WITH PALLETS THEREON RECEIVING PRINTED SUBSTRATES AND CONVEYING THEM THROUGH SAID FURNACE FOR SETTING THE BINDER COMPOSITION IN SAID PRINTED RESISTORS, AND AN AUTOMATIC RESISTANCE CONTROL DEVICE, A RESISTANCE INSPECTION DEVICE ADJACENT THE OUTPUT SIDE OF SAID APPARATUS AND ELECTRICALLY CONNECTED TO SAID RESISTANCE CONTROL DEVICE AND AN INK SUPPLY CONTROL DEVICE COUPLED TO SAID INK SUPPLY MEANS AND ELECTRICALLY CONNECTED TO SAID RESISTANCE CONTROL DEVICE, WHEREBY THE ELECTRIC RESISTANCE OF PRINTED RESISTROS IS AUTOMATICALLY CORRECTED BY ADJUSTING THE AMOUNT OF INK SUPPLIED BY SAID INK SUPPLY MEANS IN RESPONSE TO A DEVIATION OF THE RESISTORS IN ELECTRICAL RESISTANCE FROM A PREDETERMINED VALUE.
