Abstract There is disclosed a printing press comprising an ink reservoir above the plurality of ink feed rollers in communication with said reservoir, at least one inking roller disposed below and in communication with said feed rollers, a plurality of ink application rollers displaceable into communication with said at least one inking roller by swing arms connected at one end to said ink application rollers and having tension springs attached to their other ends, a printing roller beneath said ink application rollers having a horizontal center support laid in a center notch or a carrier frame, a plurality of rollers supporting said frame for reciprocating movement towards and backwards on a horizontal rail, a paper feeding device arranged to feed paper periodically and in sequence with said movement of the frame beneath a printing block on the printing roller, entrainment means for said printing roller to rotate it at the same peripheral speed as the speed of the frame movement, and driving means for driving the frame and printing roller through a crank and a gear sector said driving means being coupled directly or indirectly with a mechanism for displacement of said swing arms of the ink application rollers.
A printing press, comprising: a plurality of ink feed rollers; an ink reservoir disposed above said ink and in communication with feed rollers; two inking rollers disposed below and in communication with said ink feed rollers, and arranged to rotate in opposite directions; a plurality of ink application rollers, including at least one respective ink application roller for each of said two inking rollers, each arranged to rotate in a respective single direction then engaging the respective of said inking rollers; a plurality of swing arms respective ones of said swing arms being connected at respective one ends thereof to said ink application rollers mounting the respective ink application rollers for displacement into communication with said ink feed rollers; a plurality of tension springs attached to the respective opposite ends of said spring arm; a printing roller disposed horizontally beneath said ink application rollers, and having a centre shaft; a carrier frame; means defining a centre notch in said carrier frame; said printing roller centre shaft being supported by said carrier frame in said centre notch; a horizontal rail; a plurality of rollers supporting the carrier frame on the horizontal rail for reciprocating movement of the carrier frame backwards and forwards along said rail; a printing block disposed on the printing roller; a paper feeding device for feeding paper beneath said printing block periodically and in sequence with said movement of the frame; means for rotating the printing roller at such an angular rate as will give the printing block the same peripheral speed as the speed of reciprocating movement of said frame and including drive means including a crank means coupled with a gear sector linked to said swing arms for providing said displacement of said ink application rollers.
