PRINTING 7 Application filed March 9, 1927, Serial No This inventio n is for improvements in or relating to printing machinery, and more particularly to intaglio engrave ployed.

a printing unit in which and printing roller is eming unit which rotatable printing comprises in combination a roller, an ink duct arranged to supply ink to said roller, a rotatable furnishing.

roller spaced apart from said rinting roller and arranged to supply roller,

to said printing ing roller from the drive of the printing roller.

Further, the present invention consists of the use, in a printing unit employing a rotat- ,p able printing roller, having inwardly of a furnishing roller directed bevelled flanges arranged at either end thereof and adapted to engagewith the ends ofthe printing roller and hold the two rollers in spaced relationship.

The invention is more particularly described withreference to the accompany in which Fig. 1 illustrates a side elevation of a prmting unit constructed according to the present invention.

Flg. 2 is an end roller, furnishing elevation of the printing roller and ink duct of the device illustrated in Fig. 1.

. Referring to the drawings which illustrate a printing British Patent is arranged to unit constructed according to No. 190,202,,a web of paper 1 receive an impression from an engraved printing roller 2 mounted above an ink duct 3.

The engraved roller 2 1s arranged to receive ink from a. furnishing roller 4 rotatably mounted in the ink duct 3, and the surplus-ink printing roller 8 in a perfectlywell known manner.

The bevelled flanges 5 are arranged to engage with the ends of the roller 2 so as ing' roller 4 in spaced relationship to the en graved roller 2. mountedupon a spindle 6 so axially relativel thereto. adjusting the.

and one flange are moved relatively to the spindle6 so as to adjust the axial position of the roller 4 to the roller 2, whereupon one of the flanges is screwed upon the spindle 6 so as to correctly space'the two rollersapart from one another.

1 Due to the fact that the faces of the flanges 5 are bevelled, the space between the surface of the furnishing roller and the engraved printing roller may be accurately regulated, and further, the bevelled flanges mounted on the furnishing roller oflt'er very simple and "efficient means of driving the furnishing roller by friction from the engraved roller,

which ofler's the advantage'of enabling the two rollers to be easily dismantled from the rinting unit.

Thus it will be seen that according to the present invention there is provided a furnishing roller adapted to be driven by the engraved roller, without the surfaces of the printing roller and the furnishing rollercontacting with one another.

Further, with a furnishing roller of the above character, it is found that the em graved rolleris provided with a constant 'film of ink which is easily removed from the non-engraved portions roller by means of the doctor blade. V
