26 Claims. (01. 270-68) abandoned October 6, 1934. r

This invention relates to improvements. in

paper handling machines, particularly machines wherein paper sheets are cut apart by slitters, the divisions of the original sheet being fed in one given direction and then in a direction at right angles to the originaldirection, the slit edge of each division becoming the leading edge 7 during the right angle travel.

The invention in some respects constitutes an improvement over Hitchcock Patents 1,831,245 and 1,831,246, whereinthe edge of the original sheet opposite the guide edge is trimmed in order to make it parallel with the guide edge and provide an accurate leading edge for one of the sheet divisions, accurate leading edges being essential for the purpose of maintaining the sheet divisions square for their travel through the balance of the machine and consequently'for securing accuracy in the further operations performed upon the sheet divisions.

In the Hitchcock patents referred to above, the

two sheet divisions are moved laterally away from each other, the original guide edge and the trimmed edge becoming the leading edges of the divisions in their lateral travel. In my invention on thecontrary, the slitter formed edgesof the divisions of the original sheet become the leading edges in the lateral travel of the sheet divisions and as the slitting knives produce a cut which'is absolutelyparallel to theoriginal guide edge of the sheet, the slitter formed edges of the sheet divisions are satisfactory both for leading and guide edges.

One of the objects of the invention therefore is the production of a machine in which divisions of an original sheet may be fed through afolding or other paper handling machine accurately and economically through utilization of the slitter or. cutter formed edges .of said divisions as leading and guide edges.

Another object is the provision of a machine of the class described which shall be simple in construction and shall occupy a minimum of floor space.

Other objects and features of novelty will appear as I proceed with the description of that embodiment of the inventionwhich', for the pur-v poses of the present application,'I have illus-X in the accompanying drawings, in

trated which:-

1 driving connections, and

Fig; 1 is a plan view oi a folding machine embodying my invention; i I Fig. 2 is a vertical section one larger scale, the section being taken substantially on the line 2-2 of Fig. 1; 5

- Fig. 3 is a transverse'vertical sectional view taken substantially on the line 3--3 of Figs. 1

and 2-; a 1 o Fig. 4 is a diagrammatic plan view showing 10 carries a cross fold section, a further cross car- 20 rier, a final fold section; and a stacker.

The primary feed table is shown at H, and comprises a series of diagonally arranged driven rollers 12 and a side guide 13 which is preferably adjustable. An adjustable mounting for'the guide 25 is indicated at M, and it is to be understood that at least one other mounting of the same kind will be utilized, it being possible by means of these mountings to move the side guide bodily toward and away from the edge of the table and to vary' 30 its direction in such manner as to insure accurate feeding of the sheet. Atthe' forward end of the feed table I i there are feed rolls l5 and H5 which direct the sheet through a pair of guide plates H and 18 into the first or. primary foldsection 35 of the machine.

The-primary fold section is of the buckle fold type and may be entirely conventional in con 7 struction, embodying fold plates 59 and 20 and v feeding and folding rolls 2!,22, 23, 2 4 and 25. .40 Itwill be understood thatin thisfirst fold sec tion of the machine the sheet may have im-' I parted thereto one or more folds'in parallel, provision being made, as isusual, for disabling any part or all of the fold plates.

' a central pair of slitter knives 29 and one or more additional pairs of slitter knives 30 spaced 50 away from the central pair. In the drawings there are three pairs of knivesillustrated, but it is to be understood that this number may be varied to' suit therequirements of the particular job in hand, that is to say a centralpair only I 575:

built preferably in three 15 Somewhat below and somewhat forward of the slitter shafts 2i and 28 I mount a square rod 32 which extends transversely of the central unit of the machine frame and is rigidly secured to the frame members. Upon this red I mount deflector elements 33 each of which, as shown particularly in Fig. 5, comprises an inclined deflect ing surface 35 and a pair of clamp plates 37, through one of which extends a clamping screw 38 by means of which the deflector element may be fastened in place upon the rod 32. It will be understood that these deflector elements may be positioned at any desired points along the length of the rod. On one side of the vertical plane through the middle set of slitter knives 29 the deflector elements are mounted on the rod 32 in the relation shown in Fig. 5. On the other side of that plane the deflector elements are turned over to position the surfaces 36 on top, the,

clamping plates 2? then straddling the rod 32 and the screw 33 engaging the rear side of that rod, as indicated in dotted lines in Fig; 2. The deflector elements at the right-hand side of "Fig. 1 therefore direct the sheet divisions on that side of the machine downwardly into the grip of a pair of feed rolls 3%, while the deflector elements on the left-hand side of the machineguide the sheet divisions onthat side forwardly in a more or less horizontal direction into the grip of a pair of feed rolls 5G. The divisions which pass through the feed rolls sestrike a deflector plate &5 and are guided thereby into the grip of a further pair of feed rolls d2.

Slightly below the level of feed rolls 4!] and extending transversely of the machine in front of said rolls, there is a cross feed table 33 comprising a series of driven rollers 34 arranged diagonally at a proper angle for the feeding of sheet divisions toward the right, as viewed in Figs. 1, Sand 4. Below the table 33 and slightly below the level of feed rolls i?! there is mounted in the machine frame a second cross feed table 45 carrying a series offeed rollers d5 arranged diagonally at a proper angle for the feeding of sheet divisions toward the left, as viewed in Figs. 1, 3, and i of the drawings.

On each of the cross feed tables 43 and 45 there will be one or more side guides, depending upon the number of divisions being handled upon such table. These guides are removable and adjustable. In the present case, where the original sheet is cut into four divisions, two side guides are provided for each cross feed table. On the upper table 43 I have shown an outer long guide 47 and an inner short guide 63. The left end of guide 48 stops short of the plane through the left-handed pair of slitter knives 36, so as not to interfere with the travel across the table of the sheet division A, see Fig. 1. On the lower table 45 there are similarly a long outer guide 4e and a shorter inner guide 58. All of these guides may be provided, if desired, with balls 55 loosely mounted in circular openings in flanges of the guides, for the purpose of improving or otherwise affecting the traction of the table rollers on the sheet divisions. 1

In the right-hand unit of the machine, at

the delivery end of the cross feed table 13, there is positioned a ross folding section which may comprise fold plates 52, 53 and 5 1 and feeding and folding rolls 55, 56, 5?, 5S and 59. These rolls and plates are wide enough to receive and fold both of the sheet divisions A and A and as is well known'in the art they are adapted to make theirfolds without regard to the timing of the sheets. Hence the fact that the sheet division A will reach the fold section slightly in advance ofthe sheet division A is of no moment. When a sheet division is delivered from the fold section by the rolls 58" and 59, it is directed by a guide plate 653 into feed rolls 6% and delivered by those rolls onto a cross carrier 62, having diagonal rollers 63 and two sheet guides 66 and 65. The table may also be furnished with a set of driven rollers 56 for assisting the travel of the sheet division A crosswise of the table.

The sheet divisions traveling on the lower cross feed table d5 enter a fold section which may comprise a fold plate 68 and feeding and folding rolls 6}, 53 and 69. The sheet divisions after passing through this fold section are directed by a guide plate lfi through a pair of feed rolls it onto a cross feed table '52 carrying diagonal rollers l3 and a set of straight rollers Ml similar to the rollers 56 above referred to. There are sheet guides '55 and It on this table also for stopping the transverse motion and directing the longitudinal motion of the sheet divisions B' and B It will ben-oted that I have illustrated the cross fold sections at the left and right-hand sides of the machine as of different capacity, that is with respect to the number of folds which may be imparted, but it should be understood that sections of th same capacity may be employed if desired.

The cross carrier l2 delivers heet divisions B and B in two parallel paths to a further fold section which may comprise a fold plate i? together with feeding andfolding rolls i8, i9 and The sheet divisions after passing through this fold section are directed by guide plate 65 through a pair of feed rolls 82 onto a stacker belt 83 driven at'slow speed, and from this belt the completed divisions or signatures are or may be collected upon a tray 84.

At the right-hand side of the machine, the sheet divisions delivered by the cross carrier 62 may be caused to pass through a further fold section, not shown in detail, but illustrated as including feeding and folding rolls 85 and 86. From this fold section the divisions are delivered onto a stacker belt 82- and thence onto a tray 88.

While the details of the driving mechanism may be varied more or less, I have illustrated diagrammatically in 4 the main features of one driv ing system which I consider satisfactory for the purpose. In this system two motors 85 and fi l are employed partly for the purpose of simplifying the driving connections, and partly for t e purpose of making it possible to eliminate the drive to part'of the machine quickly and easily when the job inhand does not require the operationof that'part. For the sake of clearness the portions of the machine which are driven from motor -96 are shownse'parate from the remaining portions of the machine.

The rollers E2 of the primary feed table are shown as driven by an endless belt 9! through a shaft 92 and bevel gears $3 and M, the bevel gear 95 being fixed upon a shaft 55 which may be a continuation of the motor shaft. The belt Si engages the lower surfaces of the rollers I2, drivingthern byfriction, as is well known in the art. The first roll 2 l of the primary fold section may be driven by bevel gear 98 from a bevel gear 9'5 fast on shaft s5, and the other rolls of that fold section may be driven by a gear train 95 which Attached to one of the gears of the train all is a bevel S9 meshing with a bevel gear not on a short shaft iiil which carries at its opposite enda bevel gear, 58?. that meshes with a bevel gear Hi3 a shortshaft for driving an endless belt this belt contacting the lower surfaces of rollers to drive them in a manner well known in the art. I V

The rolls of the fold section at the delivery end of table d3 are driven through a train of gears L15, one of which be directly connected with shaft 95. A shaft tilt, driven by bevel gearing from shaft may operate, as. shown-through bevel gearing to drive: an endless belt which contacts against the lower surfaces of rollers 53 to drive the latter. A further shaft its is rotated through bevelgearing by shaft l 55, and this shaft E53 is oper-atively connectedtoendless belt N39 for the d ing of rollers 63 and for the rotation of folding rolls 85 and 8t. 7, a

Motor 98 drives shaft l ilhwhich in turn drives shaft ill, by means of which endless belt H2 is operated'to drive rollers 46 in table 15. roll 59 is driven by bevel gearing from shaft H6, and the other rolls of that fold section are operated by a train of spur gears i if; Rollers it of table E? are driven by, a belt MS from shaft Mil "by a short shaft l M'and bevel gears. The shaft H5 extends along one side of the table '52, being driven from shaft Hi3 by bevel gearing. This shaft operates through bevel gears and a short shaft H5 to drive an endless belt ill by means of which diagonal rollers i3 are driven. The roll 'E8 of the final fold section on this side of the machine is also driven by bevel gearing from shaft 555, and the other rolls of this fold section are driven through a gear train 5 l8. -t will be appreciated that some. of the elements of the above described driving system have been omitted for the sake of .clearness, it being my intention merely to show themcre or'less essential features of the system. 'f

When the original sheetis to be folded without being separatedinto divisions, or when two divisions only are required, all of the deflector elements 36, 3? may be set to direct the sheet or the two divisions thereof, asthev case maybe, onto the, upper cross food table 53. In that event the lower cross feed table and the parts carried by the left-hand frame unit are not required. Hence the motor 9% will be permitted to remain effected. Of course this feature of the invention may be omitted if desired, andthe entire me'ohae nism connected together by suitable means for 7 taking driving energy from a single motor, it be cross folder.

original sheet, after passing'through the primary fold section, will have their movement stopped by The fold idle, and a corresponding saving in power will be This shaft is folded sheet divisions A for the purpose of, assisting their travel across the table and into engagement with the side guide ll.

Operation-Assuming that it is desired to divide the originalsheet into two, thrceor four di only the'short guides 43, 58,65 and it will be removed from the tables d3, 35, 62 and it.

I The lefthand sheetdivision will then be carried onto table 53 against'guide ll and caused to travel toward the right into the right-hand cross folder, while the right handsheet division wiil'be carried onto cross feed table 5.5 up against guide Wand caused to traveltoward the left and into theleft-hand In'both'cases the divisicnspof the the guides at and so respectively, the original leading edges or folded edges becoming the guide edges of the divisions for their travel uponthe cross feed tables. l 1

The guide edge and leading edge of theoriginal sheet are assumed to be at right angles to each other. The cut made in the sheet by the slitter Knives 2% isnecessarily parallel to the guide i3 and theside and guide edge of the sheet,'and

will be exactly right angles to the leading edge of the original and the folds-impartedthfieto'by theprilnary fold section, provided, the leading and guide-edges of the original sheet were squarewith eachother. Whenthe folded sheet divisions strike against the guides ll and 39 their folded 'edges'becorne' the new" guide edges-for the lateral travel of the divisions upon the cross feed tables,and the .slitter or cutter f ormed edge of each division becomes its leading'and' front registering I edge.

The new guide 'edgeand leading edge-of each sheetdivision are therefore square with each other, and further operations performed upon the sheet divisions will be square with the previous folds. In order that the slitter'formed edge in each case become the leading and front registering edge on the cross feed table, the divisions are preferably fedso as to pass each other in their travel, that is the right-hand division moves'to the left and the left-hand division moves to the right. v

, When the original sheet into four divisions, all of the slitter knives 2d and till illustrated in'the drawings are utilized, and all of the sideguides are used. The four sheet divisions are then delivered onto tables 3 and i5, asi ndicatedat A, A B and B 'in Fig. I

1, each cross feed table carrying two sheet divisions either into'the right'or into the left-hand cross fold sections. The leading edges in every case, it will be observed, are 'slitter formed edges.

After beingfolded in the cross fold sections, or

I passed'through those sections without folds, as

the case'rnay be, the sheet divisions are delivered onto the cross carriers 52 'and'iZ and the slitter formed edges of the divisions engage the two side guides thereon. The slitter or cutter formed edge of each division then becomesa side registering andguideredge and said divisions are delivered to the final fold sectionsby the cross carriers 62 and'lZ and'passed therefrom onto the stacker belts 83 and 8f in separate piles,*each pile containing signatures of. one kind only.

work to be done calls for slitting the I If three signatures only are printed on the full-sized sheet, one pair of knives 38 is removed. Assuming that the right-hand pair of knives is removed, then the side guides 50 and 76 are also removed. Two signatures then travel over the upper cross feed table 43 and through the balance of the machine illustrated. at the right in Fig. 1, while one signature travels over cross feed table 25 and through the balance of the machine illustrated at the left in that figure. While it will seldom be necessary, it is within the purview of the invention to employ more than three sets of slitter knives, and more than two side guides on some or all of the cross feed tables, the arrangement and operation of the machine when so equipped being readily apparent to those skilled in the art from the foregoing description.
