SHEET-FED ROTARY PERFECTING PRINTING PRESS Filed July 21, 1957 INVENTOR W %/yraky ATTORNEY S ?tented QFFICE SHEET-FED RQTY PERFECTING at an PSS Howard M. arber, Pawcatuck, Conn assignor to C. B. (lottrell & Sons Compan R. I., a corporation of Delaware Application July 21,
In sheet fed rotary perfecting presses where quick drying inks and drying units are employed, it is very desirable that the several units be so located with respect to one another as to '5 produce the best results while being arranged so that access to the several units may easily be attained.
The object of my invention is to so locate the printing units, drying unit, the sheet supply, sheet A practical embodiment of my invention is represented in the accompanying drawing which is a diagrammatic side elevation of so much of a printing press as will give an understanding of my invention.
The first printing unit comprises an impression cylinder I, its diametrically opposed sheet taking devices 2, form cylinder 3, and inking mechanism 3.
The second printing unit comprises an impression cylinder 5, its diametrically opposed sheet taking devices 5, form cylinder 6, and inking mechanism 6.
These two printing units are located in difl'erent horizontal planes and in line with each other.
The drying unit comprises a heating device i (in the present instance a series of gas burners), a cooling device 8 (in the present instance a series of cold air blast nozzles) said devices being arranged over and to coact with a horizontally disposed traveling endless carrier 9 having sheet taking devices It.
Said drying unit is located below, between and 45 in line with the printing units.
A horizontally disposed insulated sheet guide it is located within the traveling endless carrier and beneath the heating .and cooling devices of the drying unit.
A shield i2 is interposed between the drying unit and the impression cylinder ii of the second printing unit to prevent the vapors from the drying unit from having any efiect on the impression cylinder t or the sheets carried thereon.
A sheet supply I3 is located at one end of the feeding means, transfer carriers and sheet dey, Westerly,
1937, Serial No. 154,706
press, and rotary sheet feeding means l4 having a sheet taking device it is arranged to coact with a sheet feeding table it to feed the sheets in the well known manner to the sheet taking devices 2 of the impression cylinder I of the first printing unit.
Said sheet supply l3 and feeding means it are located in line with the several other units of the press.
A rotary carrier ll, having a sheet taking device it, is interposed between the impression cylinder l of the first printing unit and the traveling endless carrier 9 of the drying unit. The sheet taking device it of the rotary carrier ii is arranged to transfer sheets from the sheet taking devices 2 of the impression cylinder 5 to the sheet taking devices ll] of the traveling endless carrier 9 of the drying unit.
A second rotary carrier l9 having a sheet taking device 20 is interposed between the impression cylinder 6 of the second printing unit and the sheet delivery endless carrier 2| having sheet taking devices 22. Said sheet taking devices 22 are arranged to take the sheets from the sheet taking device 20 of the rotary carrier l9 and deliver them to a sheet delivery pile 23 located at the opposite end of the press from the sheet supply it.
Said rotary carriers ll, It, said sheet delivery endless carrier 2!, and said delivery pile 23 are all located in line with one another and with the several other units of the press.
It is to be understood that any suitable heating medium, such as gas, may be supplied to the heating device i of the drying unit and that any suitable cooling medium, such as cold air, may be supplied to the cooling device 8 of the drying unit.
It will also be understood that any well known or approved means may be employed for driving the several units of the press.
It will also be understood thatthe sheets are controlled on the surfaces of the cylinders of the respective units by means of sheet guides and/or other well known or approved means, not shown. i
It will also be understood that any well known or approved quick drying inks may be used in the printing units.
It will be seen that the sheets as they pass from the first to the second printing unit are subjected to the action of heating and cooling devices I and 8 while being held on the traveling endless carrier 9 of the drying unit.
The parts shown, described, but not claimed herein form the subject matter of my copending application, filed July 21, 1937 Serial No. 154,705.
It is evident that various changes may be made in the form, construction, and arrangement of the several parts without departing from the spirit and scope of my invention, hence I do not intend to limit myself to the embodiment herein shown and described.
What I claim is:
1. In a. sheet fed rotary perfecting printing press, first and second printing units, means for feeding sheets to the first printing unit, a drying unit located between the printing units and comprising a heating device and a cooling device and a horizontally disposed traveling endless carrier coacting with said heating and cooling devices, a delivery and two rotary transfer carriers, one located between the first printing unit and endless carrier and the other between the second printing unit and delivery, said units and transfer carriers having sheet taking devices for forwarding the sheet through the printing and drying units.
2. In a sheet fed rotary perfecting printing press, first and second printing units, means for feeding sheets to the first printing unit, a drying unit located between the printing units and comprising a heating device and a cooling device and a horizontally disposed traveling endless carrier located beneath and coacting with said heating and cooling devices, a delivery and two rotary transfer carriers, one located between the first printing unit and endless carrier and the other between the second printing unit and delivery, said units and transfer carriers having sheet taking devices for forwardingthe sheets through the printing and drying units.
3. In a sheet fed rotary perfecting printing press, first and second printing units, means for feeding sheets to the first printing unit, a drying unit located between the printing units and comprising a heating device and a cooling device and a horizontally disposed traveling endless carrier located beneath and coacting with said heating and cooling devices, a sheet guide located within the endless can'ier beneath the heating and cooling devices, a delivery and two rotary transfer carriers, one located between the first printing unit and endless carrier and the other between the second printing unit and delivery, said units and transfer carriers having sheet taking devices for forwarding the sheets through the printing and drying units.
4. In a sheet fed rotary perfecting printing press, first and second printing units, means for feeding sheets to the first printing unit, a drying unit located between the printing units and comprising a heating device and a cooling device and a horizontally disposed traveling endless carrier located beneath and coacting with said heating and cooling devices, a shield located between the drying unit and the impression cylinder of the second printing unit, a delivery and two rotary transfer carriers, one located between the first printing unit and endless carrier and the other between the second printing unit and delivery, said units and transfer carriers having .sheet taking devices for forwarding the sheets through the printing and-drying units.
