Title: Improvements in or relating to a method of and apparatus for drying printing ink containing a volatilizable inflammable solvent after such ink has been applied to a material
IPC: B41M7/00
Filed: 1939-05-02
Abstract: 528,270. Gas burners; electrically igniting burners. INTERCHEMICAL CORPORATION. May 2, 1939, No. 13093. Convention date, May 3. 1938. [Classes 75 (i) and 75 (iii)] [Also in Groups XIII, XVI and XXIX] Ink is dried on a printed material, by passing it beneath gas burners 40 and supplying secondary air at 80 to cool the burners and aid combustion of volatilized ink solvents, and varying the rate of supply of secondary air and of mixed air and gas to the burners, which give a long flame striking the printed surface, in accordance with the speed of travel of the material, burnt gas being continuously withdrawn at 90. Additional cooling air is supplied when the press stops. Printed paper. passes over a roller 10 under the burners to a water cooled roller 18 where cool air passes over the paper at 94 to a rewind roller 22. The burners 40 comprise a sectional metal tube 44 with a lower gas distributing chamber 46 with ceramic plates '52 grooved to form jets; a piston 68 on a screwed rod 70 may be used to control the effective width of the burner by cutting off gas from the end jets. The burner is lit electrically by a spark continuously flashing about 20 times a second and may be arched over the paper. The flame in the centre may be cut out by a T-block fitting in a trough combustion chamber of the jets if there is no printing in the centre of the paper. Baffles direct the cooling air from the pipe 80 over the burners on to the paper. The rate of feeding fuel to the burner is controlled in accordance with the speed of the paper by a diaphragm valve 104 actuated by pressure in a pipe 106 of a fluid circulated by a pump 110 driven at the speed of the press. The fluid passes from the pump through a pressure relief valve 108 to the pipe 106 and through a manual regulating valve 114 to an expansion chamber 116 and through a pipe 118 to the pump. A second control valve in the circuit may vary the supply of cooling air to the pipe 80. A pipe 122 supplies extra cooling air when the press stops and the burners are extinguished. Dampers 128 in the air supply pipes are then fully opened by a solenoid 134 energized when the press stops. In a modification the burner casing has tubes therethrough collecting burnt gases, which pass off centrally and at the ends. Specification 522,654, [Group XIII], is referred to.
