Barber, Pawcatuck, Conn, assignor to C. B. Cottrell & Sons Company, Westerly, R. l, a corporation of Delaware Application March 2,1938, Serial No. 193,399 5 Claims. (Cl. 10l-179) In high speed web perfecting rotary printing presses where quick drying inks and web drying units are employed in connection with the web .printing units, it is most important that the several units be so located 'with respect to one another as to produce the best possible results with a minimum amount and best arrangement of the occupied space and a minimum travel of the web. This is particularly desirable where a press of this type is combined with slit-f ting, associating, cutting, and sheet collecting mechanisms. v v This invention includes first and second printing units'arranged at right angles to each other,
a dryingunit being providedfor the first print-v ing unit and, if so desired, a drying unit being,
also provided for the second printing unit. Means arealso provided for passing the web through said printing and drying units in a predetermined path and delivering the web to a predetermined Poi t- This invention more particularly includes a first printing unit, a second printing unit extending substantially at right angles from the front end of the first printing unit, drying units for the first and second printing units, a web reversing means between the first drying unit and the second printing unit, and means for. passing the web from the sheet supply rearwardly under the first drying unit, through the firstprinting unit, forwardly through the first drying unit, forwardly'under-the first drying unit to the reversing means,- rearwardly under the second drying unit, through the second printing unit, forwardly through the second drying unit, and finally forwardly under the second drying unit to a predetermined point.
A practical embodiment of my invention is represented in the accompanying drawings, in
which a Fig. 1 represents in diagram, a plan view of thepress together with the slitting, associating, sheet cutting, and collecting and delivery mechanisms associated therewith;
Fig. 2 represents in diagram a verticaLsection, taken in the plane of the line II-lI of Fig. 1', looking in the direction of the arrows; and
Fig. 3 represents in diagram, a vertical section, taken'in the plane of the line III--III of Fig. 1, looking in the direction of the arrows.
The first printing unit is herein represented as,
adapted to print in five colors upon one side of the web, the impression cylinder being denoted by I, itsfive form'cylinders by 2, 3, 4, 5, 6 and their inking mechanisms by I. 8, 9, H], II.
The second printing unit is herein represented as adapted to printin five colors upon the opposite side of the web, the impression cylinder being denoted by 12 and its five form cylinders by l3, M, l5, l6, l1 and'their inking mechanisms,
relative positions, means such as a turning bar 23 being provided for reversing the first side printed web between the printing units.
.The drying unit for the first printing unit is herein represented as comprising a large heating cylinder 24 and two small cooling cylinders 25, 26. Steam may be applied through the pipe '21 to'the heating cylinder 24 and water may be 20 supplied through the pipes 23, 29 to the cooling cylinders 25, 26. I
The drying unit for the second printing unit is herein represented as comprising a large heating cylinder30 and two small cooling, cylinders 35 3t, 32. Steam may be suppliedthrough the pipe 33 to the heating cylinder 30 and water may be supplied through the pipes 34, 35 to the cooling cylinders 3|, 32.
The web supply is denoted by 36, and it is shown as being located to the front of and in line with the first printing unit.
The delivery 37, which may be of any well known and approved form, may be located at any Convenient point. In the present instance 35 the delivery is shown as being located to the 7 printing unit.
Web slitting, turning, associating and sheet cutting and collectingmechanisms of any well 40 known or approved form may be provided for receiving the perfected web from the second printing unit .and for forwarding the product to the delivery -31 a In practice, the web is passed from the supply, rearwardly through the first printing unit, forwardly through the first drying unit around the reversing means, rearwardly through the second printing unit and forwardly through the second drying unit, when one is employed, to the slitting, associating, sheet cutting and collecting mechanisms, and thereby to the delivery.
It will be understood that suitable guide rollers may be provided wherever necessary for leading a the web in the desired path from the web supply through the printing anddrying units.
It will also he understood that any well known or approved means (not shown herein) may be employed for driving the several units 'and mechanisms, a
It will also be understood that any well known or approved quickdrying 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 printing and dryingunits of the press whereby the inks on the freshly printed sides of the web may be thoroughly dried with a minimum travel of the web, the several units at the same time being so positioned that ready access thereto may be obtained.
It will also be seen that the web, after it has I been dried dn each side thereof, is passed beheath the slitting press of the drying units, thereby eliminating the tendency of the ink to become soft because of the heat rising from the said heating members of the drying units.
It is evident that various changes may be resorted to in theconstruction, 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
7 What I claim is:
1. In a web perfecting rotary printing press, flrst'and second printing units arranged at substantially right angles to each other; drying units for the first and second printing units, each drying unit being in line with its printing unit, a web supply, and means for passing the web therefrom rearwardly under the first drying unit and through the first printing unit, then forwardly ing unit being in line with its printingunit, a web supply, means for passing the web therefrom rearwardly under the first drying imitr and through the first printing ,unit, then forwardly and through the first drying unit, then forwardly under the first drying unit, then rearwardly under the second drying unit and through the second printing unit, then forwardly through the second drying unit and then forwardly under the second drying unit to a predetermined point, and means for reversing the' web between the printing rmits.
3. In a web perfecting rotary printing press, a; first printingv unit, a second printing \mit extending at substantially right angles from the .Iront end of the first printing unit, drying imits comprising heating and cooling cylinders for the first and second printing'units, each drying unit being in line with its printing unit; a. web supply,
' and means for passing the webirom the web supply rearwardly through the first printing unit,
'then forwardly through the first drying unit,
then rearwardly through the second printing unit, then forwardly through the second drying unit and to a predetermined point. a
4. In a webperiecting rotary printing press, a first printing unit, a. second printing unit extending at substantially right anglesrfrom the front end of the first printing'unit, drying units comprising heating and cooling cylinders for the flrst and second printing units, each drying unit being in line with its printing unit, a web supply,
means for passing the web from the web supply rearwardly through the first printing unit, then forwardly throughthe first drying unit, then rearwardly through the second printing unit, then forwardly through the second drying unit' and to a predetermined point, and means for reversing the web between the printing units.
5. In aweb perfecting rotary printing press, first and second printing units arranged at substantially right angles to each other with their impression and form cylinders in similar relative locationsdrying units for the first and second printing units, each drying unit being in line with its printing unit, and means for pasing the web through said printing and drying units and to a predetermined point.
