WEB PERFECTING ROTARY PRESS FiledAug. 10, 1935 Q ATTOBNEYS INVENTOR.
BY i" Patehted Apr. 13, 1937 PATENT OFFICE WEB PERFECTING ROTARY PRESS Howard M. Barber, Pawcatuck, Qomn, assignor to C. B. Cottrell & Sons Company, Westerly, R. 1., a corporation of Delaware I Application August 10, 1935, Serial No. 35,585
. i 2 Claims. (01. 101-179) In high speed web perfecting rotary presses I where quick drying inks and web-heating and cooling units are employed, it is very desirable that the several units be so located with respect to each other as to produce the best results while occupying a minimum amount of space.
The object of my invention is to so locate the printing and combined heating and cooling units,
minimum travel of the web. I
My invention comprises, generally, first and a second multicolor printing units, located in line with each other at the opposite ends of the press, each printing unit consisting of an impression cylinder and form cylinders (in the present in-- stance four form cylinders) arranged around its upperside, inking mechanisms for the form cylinders, first and second combined heating and cooling units located in substantially the same horizontal plane, between and below the printing units, each combined heating and cooling unit comprising a heating cylinder and one or more (in the present instance two) cooling cylinders, and a web supply roll located between and in line with the combined heating and cooling units;
means being provided for passing the web from the supply roll to and through the first printing unit, then to and through the first combined heating and cooling unit, then to and through the second printing unit, then to and through the second combined heating and cooling unit, and finally directed in the desired direction as, for instance, to a point offset from and at right angles to said units.
A practical embodiment of my invention is represented in the accompanying drawing, in whichthe figure represents a diagrammatic side elevation of my' invention. The first printing unit is herein represented as a four-color unit, the impression cylinder being denoted by I and its four form cylinders by 2, 3, 4, 5, which form cylinders are arranged around-the upper side of the impression cylinder. The inkingmechanisms for the four form cylinders are 'denoted by 2a, 3a, 4a, 5a,'which inking mechanisms apply the inks to their respective form cylinders in the usual manner. This first printing unit is located at one end of the press.
The second printing unit for perfecting the web is herein represented as a four color unit, the impression cylinder being denoted by 6 and its form cylinders by I, 8, 9, III, which form cylinders are arranged around the upper side of 55 the impression cylinder. The inking mechanisms for the form cylinders are denoted by'la, 8a, 9a, Illa, which inking mechanisms apply the inks to their respective form cylinders in the usual manner. This second unit is located'at the opposite end of the press.
These twofprinting units are located in line with each other at the opposite ends of the press at the required distance apart and they are also preferably located in substantially the same horizontal plane.
The first combined heating and cooling unit is herein represented as comprising a large heating cylinder II and two small cooling cylinders l2, l3,
arranged between the heating cylinder II and the impression'cylinder I of the first printing unit.
The second combined heating and cooling unit is herein represented as comprising 'a large heating cylinder l4 and two small cooling cylinders l5, I6, arranged between theheating cylinder i4 and the impression cylinder 6 of the second printing unit.
These two combined heating and cooling units -are located in substantially the same horizontal plane between and below the printing units.
The Web supply roll is denoted by l! and it is located between the first and second heating an cooling units in line therewith. v I
The web is led'through the press as follows:
The unprinted web passes from the supply roll I! to and .through the first printing unit where the web is printed in multicolor upon one side thereof. The web is then led to and around the heating cylinder H and cooling cylinders l2,
l3 of the first combined heating and cooling unit. 'From thence the web is led to and through the second printing unit where the web is printed that'the first and second units may be driven separately either for the purpose of "inaking ready or for permitting a single or two separate non-perfected multicolor products to be produced.
It is to be understood that guide rolls are provided for passing the web in prescribed paths from the web supplyroll I! to the delivery.
It will also be understood that any suitable heating medium, such as steam, may be supplied to the heating cylinders II and I4 and that any suitable cooling medium, such as watenmay be supplied to the cooling cylinders i2, i3 and l5, l6.
It will also be understood that any well known or approved quick drying inks may be used in the printing units.
From the above description it will be seen that I have provided an arrangement of the several units 01' the press whereby the'inks on the i'reshly printed sides of the web may be thoroughly dried with a minimum travel of the web, the form cylinders of the two printing units at the same time being so'positioned that ready access thereto may be obtained.
What I claim is:
1. In a. web perfecting rotary press, first and second multicolor printing units located in substantially the same horizontal plane in line with each other. at opposite ends oi! the press, each printing unit comprising an impression cylinder v and form cylinders arranged around the upper side thereohilrst and second combined heating and cooling units located in substantially the same horizontal plane between and below the printing units, said heating and cooling units comprising a heating cylinder and one or more cooling cylinders interposed between the impression and heating cylinders, a web supply roll, and means for leading the web through said units and directing the web therefrom.
2. In a web perfecting rotary press, first and second multicolor printing units located in substantially the same horizontal plane inline with each other at opposite ends of the press, each 'printing unit comprising an impression cylinder and form cylinders arranged around the upper side thereof, first and second combined heating and cooling units located in substantially the same horizontal plane between and below the printing units, said heating and cooling units comprising a heating cylinder and one or more cooling cylinders interposed between the impresslorr and heating cylinders, a web supply roll, and means for'leading the web through said units and directing'the web therefrom at right angles thereto.
