GOTTRELL 86 p SONS COMPANY, OF WESTERLY, RHODE I SLAND, A CORPORATION DELAWARE DOUBLE MULTICOLOR WEB PERFEC'IING ROTARY PRINTING PRESS Application filed April 16,

This inventioncomprises a double multicolor web perfecting rotary printing press in which the first and second printing units are arranged at right angles to eachother, with the provision of an interposed web turning device. 4

This invention further comprises a printing press of the above character in which the printing units are located in the same horizontal plane so that the corresponding inking mechanisms of both printing units Wlll be subjected to the same temperature. for ensuring the proper distribution and laying of the inks.

This invention furthercomprises a press of the above character in which the plate cylinders of i posed around their impression cyllnder at one side of its horizontal central plane.

This invention further comprises a press of the above character in which the plate cylinders of each printing unit are disposed around the upper cylinder so that the web may be located under the inking mechanisms for sald plate cylinders, thereby causing all web paper dust to drop away from rather than into the inking mechanisms. This arrangement of the plate cylinders also permits a downward pressure at all times on the impression cylinder shaft bearings.

A practical embodiment of my invention is represented in the accompanying draw ings, in which Fig. 1 represents diagrammatically a top plan view of the press with the inking mechanisms removed;

Fig. 2 represents diagrammatically a View of the press with the first printing uni-t shown in side elevation and the second printing unit in end elevation; and

Fig. 3 represents diagrammatically a detail view showlng the second printing unit in side elevation. I

In the first printing unit of the press the impression cylinder is denoted by 1 and its 2, 3, 4, 5, which plate plate cylinders by cylinders are shown as arrangedaround the impression cylinder.

ing mechanisms 6, 7, 8, 9 of any well knqwn or approved form. I

In the second printing unit of the press the impression cylinder is denoted by 10 and its plate cylinders by 11, 12, 13, 14, which plate cylinders are arranged around the upper side of. the impression cylinder.

These plate cylinders are provided with inking-mechanlsms 1 5, 16, 17 18, of any well known or approved form.

Thetwo printing units are arrangedfi'n' substantially the same horizontal plane'so "that the eorrespondmg inking mechanisms of the two printing units will be subjected to the same temperature for faci'litating th e distribution and laying of the inks.

The two "printing units are arrangedat substantially right angles to each other and a web turning device 19 is placedbetween the two printing units, to change the direc-, tion of travel of the web after first printing unit. r I

The web 20 to be printed'in multicolor on both sides is shown as passing ;from its over a roll 22 'and undera supply roll21 p around the upper side of the roll 23 to and impression cylinder 1 of the first printmg From thence the web printed in multicolor unit under the plate cylinders 2, 3, 4, 5.

11,12, 13, 14. From thence the web printed: in. multicolor on both sides is led under a roll 26 and througha cutting mechanism, such, for instance, as a pairof coact-' ing rotary cutters 27, 28.

An offset web 2% is shown aslbeing fed. from its supply roll 30 to "and around the impression cylinderlO of the second printing unit and from thence to its take-up roll 31. I

The two printing units of the-press may be driven from a common source of power, such, for instance, as an electric motor 32 which is herein shown as having a pulley I and a belt drive connection 33. 34, 35, with a cross sh'aftl36 connected through a train it has left the the same horizontalplane and by locating the plate cylinders of the two printing units around the upper sides of their respective impression cylinders "a number of advantageous results are obtained. As hereinabove set forth, this arrangement permits the use of two similar printing units with corresponding members in the same horizontal plane. It also permits the web to be located under the inkingmechanisms of the two printing units so that all paper dust will drop away from rather than into the inking mechanisms. It will also permit the corresponding inking mechanisms of the two printing units to be subjected to the same temperature, to facilitate the distributing and laying of the inks. This arrangement also ensures a downward pressure at all times on the impression cylinder shaft bearings.

It is evident that various changes may be resorted to in the construction, form and arrangement of the several parts without departing from the spirit and scope of my invention, and hence I do not intend to be limited to the particular embodiment herein shown and described, but

What I claim is 1. In a double multicolor web perfecting rotary printingpress, first and second multicolor printing units located at substantially right angles to each other, and a web turning device located between the printing units, each printing unit comprising an impression cylinder and a plurality of plate cylinders arranged around the impression cylinder at one side of its horizontal central 7 plane.

2. In a double multicolor web perfecting rotary printing press, first and second multicolor printing units located in practically the same horizontal plane and at substantially right angles to each other, and a web turning device located between the printing units, each printing unit comprising an impression cylinder and a plurality of plate cylinders arranged around the impression cylinder at one side of its horizontal central plane.

3. In a double multicolor web perfecting rotary printing press, first and second multicolor printing units located at substantially right angles to each other, and a web turning device located between the printing units, each printing unit comprising an impression cylinder and a plurality of plate as my invention, I have signed my name this 11th day of April,.l930.
