  • Patent number: 4402265
    Abstract: There is disclosed, printing apparatus including a drum having oppositely facing semicylindrical saddles mounted thereon with elongated spaces between the edges of the saddles. The longitudinal edges of the saddles are beveled radially inwardly on themselves and an elongated laminated alternate pole magnet array is mounted in the space between the saddles. A flexible printing plate is provided along one edge thereof with an inwardly bent angle for engaging the beveled edge of the saddle and the opposite edge of the plate is provided with a lockup pad for magnetically engaging the elongated magnet in the space.

  • Patent number: 4178097
    Abstract: Method and apparatus for automatically producing finished lithographic plates from supplies of blank plates and negatives. The apparatus provides automatic sequential steps of coating and punching the blank plates, exposing the plates through the negatives, developing and bending the plates, and delivering them to an exit station. Vacuum locks are utilized for registration throughout the apparatus to provide positive registration and prevent injury to the plates or negatives. A vacuum locked registration carriage provides positive registration between a plate to be exposed and a negative and vacuum locks are provided in the exposure station which cooperate with the carriage. The apparatus is completely enclosed to prevent contamination by dust or the like.

  • Patent number: 4154167
    Abstract: There is disclosed, a printing saddle lockup including a saddle mounted on a rotary printing cylinder and having a floating biasing bar disposed at one edge thereof. A recess is formed in the cylinder beneath the biasing bar and a cavity is formed in such bar over the recess and receives a rotary cam having an eccentric peg projecting downwardly therefrom to engage a hair pin shaped spring projecting longitudinally into such recess, such that rotation of the cam in one direction contacts such peg with one leg of such spring such that continued rotation urges the biasing bar in one circumferential direction on the cylinder and rotation of such cam in the opposite direction contacts such peg with the opposite leg of such spring whereby further rotation of such cam urges such biasing bar in the opposite circumferential direction.

  • Patent number: 4144811
    Abstract: A form roller compensator is provided for use in mounting a printing form roller in a publication printing apparatus in proper orientation relative to a printing cylinder. The form rollers in a printing machine control the amount of ink transferred to the printing surfaces of a printing cylinder for printing alphabetic and numerical characters and pictorial illustrations. The invention allows the amount of ink transferred by printing form rollers to be varied to compensate for the inordinately heavy or light supply of ink which results from pressure variations of the form rollers against impression cylinders. These pressure variations are caused by thermal expansion or contraction of the various rotating cylinders involved.

  • Patent number: 4145135
    Abstract: Method and apparatus for processing lithographic plate which includes two sprayer/scrubber stations separated by a water rinse. The fluids to be sprayed are continuously circulated through fluid feed tubes provided with externally actuable metering orifices. The valve operators for the orifices are pneumatically operated in a periodic manner to provide even dispersion of the fluid.

  • Patent number: 4064803
    Abstract: There is disclosed a printing saddle including a semicylindrical shell formed interiorly with a rocker arm recess projecting axially from the mid-portion thereof to one end thereof and also a circumferentially extending link recess projecting from the inner extremity of the rocker arm recess to one side of the shell. A biasing bar is mounted along such one side of the shell and is biased thereaway from by means of biasing springs. An elongated rocker arm is received in the rocker arm recess and pivotally mounted medially from the shell and has its inner extremity connected with the biasing bar by means of an arcuate link received in such link recess. A lock is mounted from the shell adjacent the free end of the rocker arm and is engaged by such free end upon rotation of the rocker arm to retract the biasing bar to its retracted position to thus lock such biasing bar in its retracted position. A lever handle may be provided for engagement with the free end of the rocker arm to retract such rocker arm.
