To all whom it may concern:

Be it known that 1, Alarm. BRosormK, of Hamburg, a subject of the King of Prussia, and whose post-oflice address is 38-50 Grosse' Bleichen, Hamburg, German Empire, have invented new and useful Improvements in or Relating to Intaglio-Printing -Machines, of which the following isa'specification.

This invention relates to intaglio printing machines, particularly those for producing large editions of illustrated papers and mag azines of any desired size and having a large number of pages.

The object of this invention is to produce such papers or magazines in a single machine in which the intaglio printing prooem, cutting, folding and binding of thepapers is effected in one operation.

Rotary intaglio perfecting machines printing from engraved copper cylinders hitherto constructed are always combined 'with fixed, size rotary typographic relief printing machines in cases where the'paper rinted thereby are subsequently fed to a olding apparatus. -The intaglio machine in this case produces'the illustrations and the fixed size rotary machine produces the letter-press. Intalio machines for printing illustrations and letter press on both sides ofendless-webs, which are then cut up into single sheets and distributed by a folding apparatus have not hitherto been made, owing to the great difliculties in their construction due to the intaglio printing process. As is well known, printing insuch machines is effected from engraved copper surfaces mechanid'lly connected to or depaper web with reference to, that atwhich the folding apparatus is designed to work becomes excessive, and it is then impossible to deal the web in the folding apparatus. This difliculty can only be overcome which with is an exact multiple. The paper is gen- 7 "whlch the paper is then like t by so apparatus that'it can: receive and deal with endless webs at whatever speed they are introduced. v

All folding apparatus hitherto known in which the work is supplied in an endless web are intended for-a fixed sizedfleh they only cut and fold sheets of given lengths of the greatestlengththat can be dealt erally supplied to the folding apparatus at the same speed. which corresponds to the circumferential speed of all its members. In intaglio printlng machines however the circumstances are different since the speed at which the web advances changes with each edition that is printed, not only for a different size of sheet, but also when the same size is to be supplied, owing to the cylinders having to be ground for each new form as above described and thus being redu'eedin arranging the cutting and foldingdiameter. Thus the endless paper webs which leave the printingmechamsm at different speeds have to enter the cutting and folding apparatus which work with a constant circumferential speed. Preferably the same means areemployed for cutting off single sheets as are used in the so-called all-- size machines. 7

According to this invention the web, which is printed onboth sides in the intaglio printing machine before reaching the cutting cylinders, is passed between rolls the circumferential speed of which is brought into exact accordance with that of the form cylinders by means of some known mechanism such as change speed gearing. 1n the present case however the feed rolls for the variable cutting cylinders are arranged between the printing mechanisms and cutting cylinders or the folding apparatus for such cutting cylinders and are not, as inthe all-size machines above mentioned disposed between the roll of paper and the cutcylinders or printing mechanism to tin delivered. According to this invention the feed rolls which'rotate at the same speed as the form cylinders, carry the-paper web between the cutting cylinders into a system of bands or cylinders are therefore constructed e so-called all-size ders i. 6. they do not fit closely together but have a space or gap through which the web cutting .tapes leading to the folding cylinders. The

cutting cylinlongitudinal cutting an enlarged sectional view of ing folding cylinders. i

i The paper passes from the reel 1 through 'trated paper, large size is ratus 8 and 9, which has cut oil the length of two pages, between the vari-.

is free to pass. At each revolution they cut from the endless web a sheet the length of which corresponds to the speed of the 7 sheet which is entering. Only at that mo ment is the sheet taken over by thefolding apparatus and folded in the required mam ner.

An intaglio printing machine according to this invention is diagrammatically illus-' trated by way of example in the accompanying drawings, in whic Figure 1 is a vertical longitudinal" sectional view, partly diagrammatic, of part of a machine embodying my invention, and Fig. 1 is a similar view of the other part of said machine; the two views taken together representing the whole machine. Fig. 2 is two cooperatthe moistening or damping apparatus 0 thence into the mechanism for intagl'io printing on the fa'ceside consisting of the cutting cylinders 8, 9 i. 6. those which allowthe paper web to passfreely, or through the feed rollers 22' over the turning over'rods 23' by means of which the cut webs are placed on the top of each other in front of the all-size cutting apparatus. From' the latter the cut sheets pass through a system of bands or tapes passing over the rollers- 24 where they are-to be placed'flat on the delivery table 20. If instead of this an illusforinstance of eight pages of to be produced in which the webs cut into two strips by-the longitudinal cutter 21 and placed in two superimposed layers'by means of the turning'over rods 23, theypass from the variable cutting appasheets of able transverse folding cylinders 13 14 in order there to receive the. first transverse folding. If the newspaper or'periodical is to be delivered bound, the transversely folded sheets pass from the folding cylinder 14 over the binding cylinder 12 'so as to be folded again transversely between .the'cylinder 14 and cylinder 15, that is to sa the third variable folding cylinder. T ence the -paper, transversely folded twice. and bound, passes into the longitudinal folder 17 'into the cylinder 15. From well and 18 and thence into a fan-like discharge 19. If binding is not required, the newspa ers pass from 13, 14 direct to 14, 15.

he change speed gear for driving the feed rollers 10, 11 with a speed corresponding to the varying diameter of the printingcylinders 2 and 3 consists of 4 wheels 91, 111, 112 and 113 changeablein a well known manner for the purpose to give the cylinder 11 the desired circumferential speed.

24 are the nipping rolls of the folding apparatus.

As soonas the cutting cylinders 8 and 9 have perforated the paper web the latter is ripped off by means of the nipping rolls 24, and the separated sheet is caught atthe rolls 243 "by the grippers 13.2. of thecylinder 13.

Then the further operation may vary according to the circumstances. grippers 132 of the cylinder 13 open after a certain number of" revolutions and deliver the sheets collected on cylinder 13 to the band system 201, a rake 202 laying the sheets onto the table 20, or the grippers 132 deliver the single sheets to the folding knife 131 folding the sheet into the cylinder 14, the

folding blade 141 catching the sheet and passing it along the binding cylinder 12, the bindingdevice12l binding the, folded sheets by one or more wire staples, whereupon the folding knife 142 folds the sheets this cylinder, the folded and bound sheets pass through the rotating fan delivery 16 or through the band system 181 between two rollers 18 and the 'rocking'folding knife. 17, whereu on the fan 19 lays the longitudinally folde onto the delivery band 161. If nolon 'tu:

Either the sheets dinal folding is required the fanl6 dellvers the sheets immediately onto the delivery band 161. The members 131-and 132 of the cylinder 13 and the members 141 and 142 are adjustable relatively to each other as shown in Fig. 2. a

' For illustrated newspapers of smaller .variable size, the operation is as-follows:-

For an eight page-newspaper, the web, after it has passed the twoprinting mechanisms is longitudinally divided in the longitudinal cutter'21 into three strips, whereupon these three adjoining strips are cut by the variable cutting gear 8 and 9 into sheets of four page length. These sheets folded for the first time between 13 and 14 and at the same time out at the fold, the folding cylinder 13 being arranged in the known manner as, a cutting cylinder. Thereupon binding is effected between 12 and 14, and then the bound edge is folded for thesecond timebetween 14 and 15 and dellvered through thefan-like discharge 16.

"If the same newspaper-is to be supplied in sixteen pages, the dprinted endless web is longitudmally'divi ed by the longitudinal cutter 21 into two strips, one of which conare then transversely, I

tinues to advance in a straight ath while the second one is placed on the rst by the turning over rods 23. The rest of the operation is the same as'in the case of eight pages. If the same paper is to be supplied in twenty four pages it is divided by the longitudinal cutter 21 into three strips and two of. the same are placed by the turning over rod 23 on the third strip, the process being the same as in the case of eight pages. For changing the size the copper cylinders of the two printing mechanisms are exchanged and the speed gear for the feed rollers of the variable cutting cylinders adjusted accordingly.

What I do claim as my invention, and de-' sire to secure by Letters Patent of the United States, is

1. The combination with suitable intaglio perfecting web printing mechanism, and suitable cutting and folding mechanism, of

adjustable compensating web feeding mechanisms arranged between said printing .mechanism and said cutting and folding adapted to maintain the speedcf the .sheet entering the cutting mechanism in conform-' ity with the surface speed of said intaglio printing couples.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
