PATENT OFFICE.
CARL WINKLER, OF BERN, SWITZERLAND.
PLATE CYLINDER FOR nornnr mrAGmo PRINTING.
Application filed February 5, 1927, Serial No. 166,226, and in Germany August 28, 1925.
My invention relates to an improved plate cylinder for a rotary intaglio printingmachine, the characteristic feature of which consists in providing the interior of said cylinder with water cooling means.
It has been suggested to cool the outside or packing of the impression cylinder of an intaglio printing machine. By so doing the overheating of the packing is prevented, but the ink on the plate cylinder is but little influenced. 'By cooling the plate cylinder itself, as provided by the present invention, the first object is to keep the ink in proper condition, although, at the same time. of 1 course, the packing, by rotating in contact with the cold plate cylinder, is also continuously cooled.
,In a device for printing from gelatine fdrmes, produced by a photographic process,
I with fat inks, it has been suggested to cool the forme itself. A printing process of this character cannot however be compared with intagli o printing, because the conditions for the two processes are quite different. la 1 one case a gelatine coating and fat inks have to be dealt with,v whilst in the other case metal for'mes' and mostly thin water or benzol inks are used.
On the accompanying drawing a plate cylinder constructed according to my invention is shown, by way of example, in Fig. 1 in longitudinal section, and in Fig. 2, in cross section.-
The cylinder a consists of a light metal,-
preferably of high conductivity, and is surrounded by a mantle of sheet metal b (for example aluminum), which serves as a support for a coating 0 of copper, or other metal. This cylinder is carried by a hollow shaft d which is provided with holes towards the ends of the cylinder and is divided by a middle piece 6 into two chambers f, g. The water introduced into the shaft, at one end, fills the entire cylinder and then" passes out through the shaft, on the other side of the partition 6.
What I claim and desire to secure by Letters Patent of the United States is:
1. A plate cylinder for rotary int-aglio printing, comprising in combination, a hollow shaft, and a partition in said hollow shaft approximately at the center of length of the cylinder, the shaft being provided with a plurality of perforations on each side of the partition. substantially as, and for the purpose, set forth.
2. In an intaglio printing machine, a 1'0- taryplate cylinder formed of light metal provided with a mantle of sheet metal having a coating of copper thereon, and a hollow shaft carried by the cylinder and having its ends projecting from the cylinder, said shaft having a partition at approximately the center of the length of the cylinderand provided on each side of the partition within the cylinder with a plurality of perforations.
In testimony whereof I have signed my name to this specification.
. CARL WINKLER.
