4 Claims.
' heat in the sheets will not cause sticking when the sheets are piled one upon the other.
A further object is to produce a device of this character which will effect an even drying of the sheets, thus eliminating warping or wrinkling.
A'further object is to produce a machine of this character which is economical to manufacture and economical to operate.
A further object is to provide means for con- ;trolling the flow of air over the sheets during the drying process and to control the suction below the sheets during its travel through the machine.
Other objects and advantages will be apparent durin'gthe course of the following description.
In the accompanying drawings forming a part ofthis specification and in which like numerals are employed to designate like parts throughout the same,
' 'Fig. 1 is a side elevation of my machine;
' 2 is a top plan view of Fig. 1 having a portion thereof broken away;
Fig. 3 is a cross sectional view taken on the line 3.4 of Fig. 2;
Fig. 4 is a cross sectional view of the cooler pipe and distributing nozzles;
Fig. 5 is a fragmentary cross sectional view taken on the line 5-5 of Fig. 2.
In the printing of labels, and particularly lithograph work, the sheets are varnished and stacked.
It'has been customary to pass these varnished sheets through a long heated chamber, and it often occurs that due to the sudden changes in temperature as the sheet passed into thechamber that the sheet would fold over upon itself through a curling action, not only spoiling that particular sheet but often'the sheets ahead and the sheets following. As these sheets are quite expensive it is obvious that such a condition results in a heavy. loss.
I have, therefore, devised a machine wherein these same varnished sheets are conducted into a dryer, passed therethrough, and delivered to a stacking machine in dried and cooled condition and without curling, as above described.
This I accomplish in a machine in which ,an
elongated box like structure 5 serves as a drying chamber. By referring to Fig 3 it will be noted that this drying chamber 6 has a table surface I which is raised, so as .to form channels -8 and 9 at the sides'thereof. This table 1 has a plurality of slits ll diagonally arranged therein, which slits open into 'a vacuum box [2.
Entrance to the chamber 6 is through an open- 1 ing 13; an exit therefrom is through an opening M. The slits II are regulatedtbyi dampers l6 connected to handles 11. .Mounted at each end of the chamber '6 are rolle'rsfliland idlers 1'9."
Over these rollers and idlers are arranged belts 2| which serve'to carry sheets through the chamber 6. Conveyor belts 22 serve to: deliver sheets from the varnishing machine to the conveyor belts 2| and belts 23 receive the "sheets from the belts 2| and deliver the same to the table 24'. A
I The result of this construction is that when a sheet of varnished or coated material is delivered to the belts 22 thesebelts will advance the sheet to the opening l3 and onto the belts 2i, and it will be here noted that, two of the slits ll, designated by the letter A in Fig. 2, project beyond the chamber 6 and consequently a down draft will hold the sheet against rising as it enters the chamber. As the sheet proceeds through the chamber it will be progressively helddownwardly by the slits H 'over which it passes and at the same time the jets of air issuing from the pipes 3|, which air is heated, will expel the moisture from the sheets, which moisture will be carried to the channels 8 and 9. As the sheet leaves the chamber 6 it will pass onto the belts 23 where it will receive a down draft of cold air from the pipes 46 which may be adjusted up or down as best suits the condition encountered. The slits 43 will function in the same manner as those described at II.
It will be apparent that with my device I can I perform all the objects above set forth.
It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes relative to the material, size, shape and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.
Having thus described my invention, I claim:-
1. In a device of the character described, an elongated box-like structure, a second box-like structure forming a vacuum box positioned in said first-mentioned box-like structure in such a manner as to form channels at the side of said said first mentioned box-like structure, slits formed in the top of said vacuum box, said slits being diagonally disposedwith relation to the length of the chamber, means for conducting sheets of material through said machine and over said vacuum box and slits therethrough, and means for directing a current of air downwardly on said sheets, said means including a plurality of longitudinally arranged pipes havsaid structure, a vacuum box positioned in said structure, the top of said vacuum box supporting said belts, slits formed in the top of said box, said slits being diagonally arranged with respect to the longitudinal dimension of said structure, pipes longitudinally arranged above said vacuum box and capable of directing jets of air downwardly against sheets carried by said belts, means for rotating said pipes to change the angle of said jets issuing from said pipes, a channel formed at each side of said vacuum box, and exhaust means communicating with said channels, whereby air from said jets will pass over said sheets of material toward the edges thereof and to the channels, thereby holding the edges of said sheets against curling.
4, In a device of the character described, the combination with an elongated chamber having openings at both ends thereof, conveyor belts passing through said openings whereby a sheet of material may be transported through said chamber, a vacuum box positioned in said chamber, the top of said vacuum box supporting said belts, slits formed in the top of said box, said .slits being diagonally arranged with respect to the longitudinal dimension of said chamber, pipes longitudinally arranged above said vacuum box and capable of directing jets of air downwardly against sheets carried by said belts, means for;
rotating said pipes to change the angle of said jets issuing from said pipes, and means for cooling the sheets passing from said box to a remote point, said cooling means including a header pipe suspended above the delivered sheet, said header pipe having a plurality of angularly disposed pipes connected thereto, each of said last mentioned pipes having downwardly directed nozzles, and a vacuum box positioned beneath said header, said vacuum box having slits formed in the top thereof whereby a suction will be exerted on the bottom of the sheet being delivered.
