Definitions

  • 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.
  • 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 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.
  • 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.
  • 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.
  • Fig. 2 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.
  • 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.
