ROTOGRAVURE PRINTING MACHINE Filed March 22, 1930 Patented June 21, "1932 UNITED STATES QPATIENT or FICE' HANS FISCHER, F AUGSBUBG GERMANY, ASSIGNOR TO MASCHINENFABRIK A'UqsBURG-NURNBERG A. G., 01'' AUGSBURG, GERMANY, A CORPORATION OF GER- MANY ROTOGRAVURE PRINTING MACHINE Application filed March 22, 1930, Serial No.
The object of this invention is a perfecting sheet-fed rotogravur'e printing machine in which the impression which the sheet initially receives upon one of its sides is subjected Y to a drying process before the sheet is printed lar parts, thus lending itself upon the other side, with a.view to produce multicolor prints by coupling this machine with a second one of similar design and working the two machines in conjunction. In the novel machine the feed board is disposed above the firstimpression cylinder and foregrippers or other equivalent means convey the sheet thence to special delivery members, a delivery cylinder, delivery grippers or the like in such manner that, contrary to usage, the perfecting side of the sheetis printed first, the sheet is next carried around a drying drum and after receiving another impression fromthe second form cylinder upon the other side is delivered, last printed side face up. The term perfecting side is here used'to indicate the under side of the sheet (while on the feed board, previous to printing). A machine is thus evolved which comprises a great number of erfectly simipeculiarly to the serial mode of manufacture. Agreeable to the purpose both impression cylinders are disposed on the same level and the form cylinders obliquely below them.
Fig. 1 is a side view of a preferred form of the novel machine.
Fig. 2 is a. side view of a multicolor showing two units thereof.
The sheet arriving from feed board 1 is gripped by the grippers 2 of the delivery cylin er 3 and passed by them to-grippers 4 of the impression cylinder 5. While passing form cylinder 6 it receives an' impression upon theperfeeting side. Grippers it-hen seize it and pass it to the grippers 7 of impression cylinder 8 which convey it to .the grippers 9 of the drying drum 1 0.= Drying drum 10 takes the sheet round once, printed side up. The sheet is thereupon transferred to the second set of grippers l1 of impression cylinder 8 and while passing between surface press sectionl2 of the impression cylinder and 438,068, and in Germany March 25, 1929.
The non-print- The sheet may be conveyed from the feed board to grippers 2 in various ways, for instance, foregrippers may be provided which seize it from the feed board in order to pass it to the grippers 2. Or cylinder 3 may be a so called stop cylinder performing one complete revolution during one half revolution of the impression cylinder 5 and standing still during the second half revolution of the lmpression cylinder, thus enabling the sheet to be fed to the cylinder during its stoppage.
Or a rotating or swinging set of grlppers maybe provided in place 'of the stop cylinder; the essential feature being that in any case the sheet is conveyed to the first impresfecting side of the sheet receives the first impression by contacting with form cylinder 6.
In Fig. 2 is shown a multicolor press comprising a plurality of units, operating side by side, each printing a different color and similar in all other respects to the unit shown in Fig. 1. It will be understood that any number. of such units may be used in a series to.
produce the desired multicolor printing.
What I claim is 1. A rotogravureprinting machine" comprising two form cylinders of equal diameter, a first and second impression cylinder mounted on the same level and double the size of the form cylinders, tween said feed board and said first impression cylinder adapted to deliver a sheet to said first impression cylinder in such a manner that the side of the sheet toward the feed board is first printed, a drying cylinder cooperating with said second impression cylinder and upon which the sheet is supp rted wit sion cylinder 5 in such manner that the pera feed board, a conveyor beimpression cylinder adapted to deliver the its printed side out, said sheet thereafter bein delivered to said second impression cylin er for another printing operation, and a sheet ejector arranged at the upper side of the second impression cylinder and adapted to receive the sheet from'said second impression cylinder with its freshly printed side upward.
2. A perfecting sheet fed rotogravure printing machine comprisingtwo form cylinders, two impression cylinders mounted on the same level and of double the diameter of said form cylinders, grippers on said impression cylinders, a feed board, means for conveying sheets grippers of the first of said impression cylinders for a first printing operation, said first printed sheet directly to the Second of said impression cylinders, a drying cylinder, means on said drying cylinder for receiving the sheet from said second impression cylinder, said sheet thereafter being delivered to said second impression cylinder for a second printing operation, and means above said second impression cylinder for receiving and conveying away the printed sheet.
In testimony whereof I have aflixed my signature.
