I 22 Claims. (c1. 101-416) g This invention relates to printing and aims to provide improved apparatus for setting printing There are so-called quick-drying" inlrs'on the market at present containing solvents which are non-volatile at ordinary press room temperatures (25 C.) and which become highly volatile liquids at about 150 C. Such inks are dried and set by causing the material upon which they have been printed to travel through a furnace where the printed surface of the material is subjected to heat of such-great intensity that the solvent is volatilized instantly and solvent vapors are burned in-the furnace. Such furnaces are heated by means of a series of gas burners fixed to manifolds mounted within the furnace through which fuel consisting ,of a mixture of gas and air is supplied to the burners. These burners have not been operated at maximum efliciency in the past because it has been necessary to supply an excess of air in the fuel mixture to support combustion of the vapors of the ink solvent within the furriace. Furthermore, the heat to which the burner manifolds are subjected "in the furnace cause them to-beco'me dangerously hot. I have discovered that the burners of a furnace may be operated at maximum efliciency to supply.

dried by moving the material past a heater pro-" vided with a .gas' burner directed toward the printed surface of the material. A substantially co'r'n'pletely' combustible mixture of gas and air is burned in the heater volatilizing the solvent of the ink and burning the solvent vapor. The heater is cooled and. air is provided for,,combustion of the solvent vapor by projecting a current of air over the heater and then into admixture with the solvent vapor;

My invention includes also apparatus bymeans of which the heater is cooled and air necessary to support the combustion of .solvent vapors is 'sup- "plied while the burners of the heater are operwhich contains a heater adapted to direct intense pace.

21, communicates with the burner compartment solvent vapor.

heat upon the printed surface of the material and means are provided for distributing air from the air duct over the part of the printed surface which is adjacent the heater.

A specific embodiment of the apparatus for carrying out my invention is illustrated in the accompanying drawings in which:

Fig. 1 is a side elevation of the furnace attached to the frame of a printing press;

Fig. 2 is a plan view of the furnace; and

Fig. 3 is an elevation of the air duct.

In the apparatus illustrated in the'drawings, inlr is applied to a web of material 6 by means-oi an ordinary web press I. The material fi'merges from the .press with its printed surface uppermost and travels, in the direction indicated by the arrows, through the furnace and over rollers 8, 9, Hi and I! to rewindv roller it. The furnace through which the printed material t travels is enclosed in a casing of insulating material it attached to the frame of the printing press 1' and is supplied with heat through a series of burners fuel chamber ll. Fuel is supplied to the respective burners l5 from their manifolds It by needle.

valves IS. The burners l5 are contained in a compartment I9 which is separated from the compartment containing manifolds l6 by strips of insulating material 2| having slits 22 between their adjacent edges.

The end of the furnace which is adjacent press I is equipped with end plate 24 and a narrow opening 25 through which the printed material 6 enters the burner compartment IQ of the fur- A suction duct 26, provided with damper E9 of the furnace at its other end and communication between the suction duct and manifold compartment 20 is prevented by the member 28.

A controlled amount of fresh cool air is supplied to the manifold compartment 20 of the fur-- nace: A row of conduits and a row of conduits 3i, which communicate with manifold compartment 20,- project from end plate 24 into a tapered air duct 32 attached to that end plate. The larger end of air duct 32 communicates with blower 33 and is provided with a'dar'nper 3d.

As the printed material 6 travels through the burner compartment 19 of the furnace, its printed surface is subjected during-a very'brief period to heatfrom burners ii of suiilcient' intensity to volatilize the solvent of the ink'and ignite the At the same time, fresh cool air is supplied from blower 33 to themanifold com- I5 fixed to manifolds l6 which extend across the interior of the furnace and communicate with a partment 2U ofthe furnace. The taper of air,

duct 32 eifects a uniform distribution of air from= blower 33 to conduits 20 and 3| extending into that air duct, and it will be noted that the diameter of the conduits 30 in the upper row is larger than the diameter of the conduits ii in the lower row, thus insuring circulation of fresh, cool air over burner manifolds IE to the far end of the furnace. After the air from duct 32' passes over the burner manifolds I 6, it flows through slits 22 to the burner compartment 1 9 where it is distributed over the printed surface of the material 6 adjacent the burners i5. The air from duct 32 not only cools manifold it, but, in'passing down through slits 22, counteracts the tendency of gases contained in the burner compartment l8'to rise.

to the manifold compartment 20, and the distribution of this air over the printed surface of the and any solvent vapors which may not be burned, are withdrawn from burner compartment i9,

The amount of air through suction duct 28. supplied to the furnace through air duct 32 is controlled by damper 34, and the rate at which gases are withdrawn from the burner compartment i8 is controlled by damper 21 in suction duct 26. The adjustments of these dampers will vary with the material printed, the rate at which it is printed,'etc., and ean'best be effected by observing conditions within the furnace. The fresh air damper is most desirably adjusted so that the tail of the flames caused by combustion of the solventv vapors appears to travel along the surface of the material 8 at a speed which is substantiallythe same. as the speed of that material. Suction damper 21 is most desirably opened to a point just beyond that at which products of combustion are observed to cease traveling ,over roller 8'.
