PRINTING APPARATUS.

Application filed June 6, 1925. Serial No. 35,283.

The primary purpose of this invention is the production of apparatus for printing and numbering manifold continuous forms in an eflicient economical, and highly satis- & factory manner.

A further object is to arrange the printing and transfer cylinders of the apparatus in such position that they are readily accessible from a convenient location at all times.

In the drawing accompanying and forming a part hereof the figure is a diagrammatic representation of a. printi apparatus embodying the invention, an wherein the above mentioned objects are attained.

Manifold continuous forms of the kind produced b the apparatus herein disclosed are shown in United States Letters Patent No. 1,509,525, issued September 23, 1924.

Briefly, in the tinting of forms of this character, the printed matter of each form is repeated longitudinally of the web, and each form, being ultimately made ucp of superposed connected sheets bearing uplicate copies, is repeated transversely of the web a number of times corresponding to the number of sheets which go to make up the completed article. Ad'acent sheets are printed on opposite sides 0 the web so that when subse uently fan folded, the printed matter of all sheets faces in the same direction. Such forms are so wellknown that further detail description is deemed unnecessary. It may be added, however, that usually the web of aper is perforated transversely between adjacent forms of sets of forms, and lon itudmally between the adjacent sheets of t e res ective forms. Also, as brou ht out in the a oresaid Letters Patent, certain or all of the sheets of each form are unched for filing devices or loose leaf inders.

With reference to the ap aratus represented by the diagram of the rawing, a web W of receiving material, such as paper, is drawn from a suppl roll '1, over ides 2 and 3 through so ca led infeed rol s 4, between two cylinders designated and 5 which constitute parts of my improvcd rinting couples. he web is carried thence tween out-feed rolls 6 and com ensatmg rolls 7 to a printing couple comprised of a plate 0 linder 10 and a tympan or impression cy inder 11, the former cylinder having associated with it the usual inking mechanism 12. Besides the plate cylinder 10 which cooperates with the impression c linder 11, there is a cross perforation cylinder 13 which perforates the web transversely. The web passes from the impression cylinder 11 between numbering heads 15 which are equipped with inking mechamsms 16. The numbering heads are of usual construction and function automatically to successively number the forms as the web 1s fed between them. The web next asses between punching rolls 17 which perorate the sheets of the forms for loose leaf binders or filing posts and from thence the web is carried about guides 18, 19 and 20 and between perforating rolls 21 that perforate the web longitudinally, to rewind mechanism designated 22.

The previously mentioned cylinders 5 and 5* are combined transfer and impression cylinders. Each is an impression cylinder in the sense of sustaining the web for the reception of an impression from the other cy inder and each is a transfer cylinder in the sense that it carries from the cylinder contacting with it an impression to the web. Cooperating with the respective cylinders 5 and 5" are cylinders 25 and 25. All of these cylinders are preferably rubber jacketed and are commonly known as blanket cylinders. Cooperating with the cylinders 25 and 25 are what I shall term type cylinders 26 and 26, respectively. I employ the term type in its broadest sense. As a matter of fact the type are referably in the nature of plates precisely Ike those used in rotary presses for direct printing and are made by the same rocess. They are distinguished from ofi set printing plates by the fact that their printin surfaces are in relief. Each of the cylin ers 26 and 26 is provided with inking mechanism 30.

It will be understood that the various cylinders, rolls, inking mechanisms, etc. are geared to ether according to the usual prac-. tice, so t at the printing. numbering, perforating and punching c linders will travel at the same surface speed The type cylinders 26 and 26' are shown as carrying diametrically opposed type 105 plates p, and upon each rotation of the cylinder, said plates receive ink from the mechanism 30 and transfer it, accordin to the printed matter or designs on the p ates to the cylinders 25 and 25, and these cylinders in turn impress it upon the cylinders and 5 which impress it upon the opposite sides of the web W. As the web continues on its way it passes through the printing couple comprised of the cylinders and 11 Where a color may be laid on the web, and from thence the web passes between the numbering heads 15 where the forms are consecutively numbered.

.It will be observed that the type and transfer cylinders are arranged in a vertical line and that the inking mechanism for both type cylinders are disposed on the same side of the respective printing couples. From the other side the type and transfer cylinders may be readily reached for inspection pur oses at any time.

aving thus described my invention, what I claim 1s:--

In printing apparatus, the combination of two combined impression and transfer cylinders between which a continuous web of material is adapted to be fed, said cylinders simultaneously contacting with the opposite sides of the web on the same transverse line, means for positively feedin the web at the surface speed of said cylin ers immediately in advance of and be 0nd the line of contact between said cylin ers and the web, two transfer cylinders, one cooperating with each of the first mentioned cylinders, two printing cylinders, one associated with each of the second mentioned cylinders, a relief type plate bearing a form composition carried by each of the printing cylinders. inking mechanism for. each of the printing cylinders, and numbering mechanism to which the web is subjected for serially numbering the forms impressed thereon.

In testimony whereof, I hereunto aiiix my 40 signature.

GEORGE A. MAYER.
