Filed Oct. 23, 1957, Ser. No. 691,954 6 Claims. (Cl. 101-181) The present invention relates to a device in printing machines designed for aniline printing in order to render them serviceable for rotogravure printing through interchanging of the inking devices with a minimum of work expenditure. By aniline printing is meant a surface printing with raised forms similar to the customary printing of books, but using an aniline of watery consistency. Rotogravure printing" refers to prints obtained from a cylinder on which the design is etched below the surface.
It is an object of this invention to make possible such a combination without enlarging the machine, in order thereby to solve the attendant problems of space requirement, power requirement, simplicity and clarity of arrangement.
It is a further object to pro 'de'a machine which has economical operation and will satisfy higher artistic demands made on the print. v
Machines have already been known where both types of devices are incorporated in one and the same machine so that each of the two inking devices may alternatively be operated. It is quite obvious that this duplicity oi inking devices in such a machine will its simplicity and clarity of: arrangement, while their advantage consists only in the simple conversion which usually takes some considerable time for setting up and adjustment.
Compared to the known systems, the present invention oifers the advantage that for the inking devices, which as a practical matter can be used only alternatively, only a single space will be required and that for change-over from aniline to rotogravure printing several rollers of each inking device need but be interchanged, which performance is effected quickly and in a simple manner.
Other objects, features, and advantages of the present invention will become apparent from the subsequent description, taken in conjunction with the accompanying drawings.
In the drawings:
FIGURE 1 is a schematic side elevational view show-- ing the essential parts of the machine;
,' FIGURE 2 is an enlarged fragmentary side elevational view showing the inking device for aniline printing;
FIGURE 3 is a view similar to FIGURE 2 showing the inking device tor rotogravure printing; and
FIGURE 4 is a plan view of the block or rotogravure roller with a longitudinal section of the two bearings.
Referring more particularly to the drawings, FIGURE 1 illustrates how the paper web 1 is passed through the machine, in the direction indicated by the arrow, i.e.
H 3,007,405 Patented Nov. 1961' in the ink trough 7. Below the latter,-there is pivoted a pair of levers 8 carrying the transmission roller sothat this may be swung into or out of its operating positionbe'tween rollers 4 and 6. printing roller 4 may be displaced and adjusted in guides 9 toward and away from a line connecting the axes of rollers 3 and 5.
If-the inking devices are to be changed over from aniline printing to rotogravure printing (FIGURE 3), the transmission roller 5 is swung out, with the aid of levers 8, towards the right, after which the inking roller 6 taken out together with the ink trough 7. The print ing roller 4 is replaced by a rotogravure roller 4, which has been etched in the conventional manner, and below which an ink box 10 containing rotogravure ink is suspended carrying the conventional adjustable rasparatory doctor 11 designed to scrape off the excessive ink from roller 4'. p I
Replacement of rollers 4 by 4 is effected through a special construction of the bearings, shown in FIGURE 4. The shafts 12 of rollers 4 and 4' carry Slotted expansion collars 13 [are mounted at the outer ends of shafts 12 and can. be expanded by means of rings 14 onto cones 15 so as to become clamped in the interior races of antifriction bearings 16. Rings 14 are threadably mounted in bushings 17 for Bushings 17 carry bearings 16 andare slidably mounted in frame members 18 onopposite sides of the machine. Bushings 17 carry shouldered portions 21 which engage the outer surfaces of frames 18 to limit inward axial movement of thebushings. Since relativeaxial movement ofthe inner and through the various inking devices over a plurality of further rollers which are intended partly to stretch the paper web and, partly, with rollers 3, to convey the web and to hold the register. The inking devices are, as a rule, provided for aniline printing, as shown in FIGURES l and 2, having more rollers for aniline printing than for rotogravure printing. Each inking device incoporates one printing roller 4 carrying the printing form, e.g. a block, or clich, and resting against counterpressure roller 3. Below roller 4, there is a transmission roller 5, which also is in contact on either side, under which roller 5 thereis an inking roller 6 which is partly submerged outer races of each bearing 16 is prevented by the inherent construction of the bearings, clamping of the inner hearing races to shafts 12 by expansion of collars 13 will lock the shafits and bushings 17 together, preventing the bushings from being slipped out. On one side of the frame (at the top of the drawing in FIGURE 4), two set collars 19 are screwed into bearing bushing 17 from opposite sides, and between these collars the outer race of bearing 16 is clamped. By advancing or withdrawing set collars 19, printing roller 4 or 4 can be axially adjusted with respect to the paper web. For replacing the aniline printing roller by rotogravure roller 4', or vice versa, collars 13 are allowed to contract by backing oft rings 14, after which the bearing 17 are withdrawn and the printing roller 4, or 4' respectively, can be removed. To mount the other roller, the order of operations is reversed.
With a machine constructed in accordance with the present invention which incorporates, for instance, tour printing devices each tor printing paper webs on both sides, various operations can be performed through the above-mentioned interchangeability of the printing elements for aniline and rotogravure printing, which otherwise would 'be impossible in this quantity and diversity without enlarging the size of the machine accordingly. For example, longitudinal and transverse lines may be printed in aniline in several colors with two inking devices each. Furthermore, instead of one, two adjacent paper webs can be printed, in which case the diversity would naturally be limited for apparent reasons. Through the simple and quick interchanging from aniline to rotogravure printing, it will be possible to make use of half tones in rotogravure printing, and this moreover in diiferent colors.
While it will be apparent that the preferred embodiment of the invention disclosed is well calculated to fulfill the objects above stat-ed, it will be appreciated that the invention is susceptible to modification, variation and change without departing from the proper scope or fair meaning of the subjoined claims.
What is claimed is:
1. In a machine with interchangeable inking devices adapted for alternative use in aniline or rotogravure printing, a counter-pressure roller, printing roller mounting means adjacent said counterpressure roller for removably supporting a printing roller, whereby an aniline printing roller and a rotograwre printing roller may be interchangeably mounted adjacent said counterpressure roller so as to receive a paper web therebetween, an arm pivotally mounted on an axis parallel to and spaced from the axis of said printing roller mounting means, and a transmission roller rotatably mounted at the outer end of said arm, the effective length of said arm being substantially greater than the diameter of said transmission roller, the arm being swingable between a first position in which said transmission roller is adapted to engage a printing roller;
