Referring now .to the drawings in detail, the machine embodying the present invention comprises asupporting frame Ill on which is mounted a bearing frame for a pair of metal rollers l4 and i6 (Figs.'2 and 4). each journalled. at its opposite ends for rotation in suitablebearingscarried by frame I2. Roller I4 is spring pressed toward roller l5 bysprings l8.which are adjusted by threaded. rods LZ i mounted. in bracket arms 22 forming a part .of frame. I2. .Saidrollershave a peripherally continuous bight relation, during the rotation thereof. Therollers I4 and t6 have gears 24- 25, respectively, fixed thereto for rotating said rollers at thesame speed, said, gears being in mesh with each other. A driving gear 28 meshes with gear 26 and is driven .bya pulley 3!} connected by a belt 32 to anelectric motor 34.

When rollers 14 and I6 are rotat-edthey draw oneor more webs W of sheet material therethrough, and in accordance with the present invention the web Wis marked or printedupon and is cutinto strips of equallength and more specifically, in the present form of the invention, into lengths approximately equal to thecircumference of roller [4. Referring to Fig. .'5 the manner of marking and cutting the web is illust ated, and it will be seen that the web is marked along transverse lines spacedfrom 'each other longitudinally of the web,v namely as here shown along lines Ll andLZ adjacent the cut edges Cl and G2 at the opposite ends, respectively, ofthe strip S cut from said web. Other marking lines L3, L4, L5, L6, and L! are .appliedduring the operation of roller I4 to the portion of the web constituting said strip S, said lines being, as here shown, spaced equally from each other along the length of theweb. The means for thus marking and cutting the web will now be described.

First, with respect to the marking. means, the

latter comprises a plurality of marking bars 36 which apply the lines L3 to L6, inclusive, and a pair of marking bars 38 which apply the lines LI and L2. As illustrated in Fig. 4 said marking bars 36 and 38 are spaced from each other peripherally of roller [4 and extend longitudinally of the roller, i. e., in a direction parallel to the axis of said roller. As here shown, (Fig. 2) there are a plurality of sets of said marking bars, one for each of a plurality of webs W which is fed between the companion rollers l4 and I6. As illustrated in Fig. 2 roller I4 is provided with a plurality of peripheral grooves 48 spaced from each other longitudinally of the roller to accommodate the thickened portion 42 formed on the web when the latter is folded as illustrated in Figs. 5 and 5A.

As all of the bars 36 and 38 are of the same construction, a description of one of the bars 36 will be sufficient, reference in this connection being had to Fig. 6. Each marking bar is formed of a strip of suitable metal, for example, brass, and is provided with a plurality of longitudinally spaced projections 42 so that the lines marked by the bar are dotted or interrupted lines as illustrated in Fig. 5, thus reducing the quantity of marking material applied to the web by the marking bars so that when the lines of stitching are applied, the marking material will be sub stantially invisible. The intermediate part; of each bar is provided with a portion 44 devoid of projections 42, said part 44 of the bar being located at the peripheral groove 46 acros which the bar extends. Each bar 36 and 38 is positioned in a slot 46 in roller l4 adjacent the outer I periphery thereof and is movable in said slot radially of the roller. The bar is urged outwardly in-a radial direction by a pair of springs 48 positioned in holes 58 extending inwardly from the outer surface of roller I4. The outward movement of bar 36 is limited by the screws 52 the heads of which engage the adjacent end portions 54 of the bar. It will be understood that screws 52 permit the inward movement of bar 36 against the pressure of springs 48 and allow a limited outward movement of said bar due to the action of said springs.

.As illustrated in Fig. 6, the head of each screw 52 is arranged to engage the adjacent edges of longitudinally adjacent bars 36, when, as described herein, there are a plurality of sets of marking bars. Bars 38 are mounted in the same way as bars 36 but as illustrated in Figs. 2, 4, and are disposed closer to each other than to bars 36 and are disposed at opposite sides of the cutting member 56 so that as the web is cut into strips by said cutting member 56 line L2 is applied to the web in advance of the action of cutting member 56 so that line Ll is applied to the web adjacent the leading end thereof after the strip SI had previously been cut from the web. More particularly, referrin to Fig. 5 it will be observed that line L2 applied to strip S cut from the web W is applied to the web at the portion thereof forming said strip by one of the marking bars 38 just before the cutter member 56 engages the web and cuts the same along the line C2 after which the other marking bar 38 engages the web at the strip forming portion S2 thereof and applies on the latter the line Ll. It will be understood that this marking and cutting process is continuous at regular intervals alon the length of the web W while the latter is fed between the'rollers. It will be understood, also, that while the web passes between the rollers bars 36 act thereon to apply to each strip forming portion the marking lines L3 to L1, inclusive.

The cutter member 56 is held in a groove 58 adjacent the outer peripheral surface of roller l4 by screws 68 the heads of which engage adjacent end portions 62 of longitudinally adjacent cutter members 56 there being as here shown a cutter member 56 for each set of marking bars 38. It will be understood, however, that one cutter member can be utilized instead of a plurality of cutter members 56 in which case the single cutter member will be of sufficient longitudinal extent for cooperation with a plurality of sets of marking members.

As illustrated in Fig. 10 the marking members 38 normally extend outwardly beyond cutter member 56 and, it will be understood that each marking member 36 likewise extends radially outwardly beyond cutter member 56 whereby to permit marking members 36 and 38 to engage the ink-applying roller 64 without engagement of the latter by the cutter member 56 during the rotation of roller l4. Further, it will be understood that as the marking members are brought into engagement with the ink-applying roller 64 the outer surfaces of the projections 42 of the marking members engage said roller resiliently by reason of the pressure of springs 43 and that in passing said ink-applying roller the marking members 36 and 38 are moved inwardly toward the center of the axis of roller l4 against the pressure of the companion springs 48. Ink is applied to the roller 46 by a transfer roller 66 which, in turn has the ink applied thereto by the supply roller 68. Said rollers 64, 66, and 68 are mounted for rotation in an auxiliary frame 18 supported by bracket arms 22. Roller 68 is driven by a pulley 12 rotated by a belt 14 driven by a pulley T6 fixed to the shaft of roller l4 and rotated thereby. The set of rollers 64, 66 and 68 is of the type utilized in printing machines and as usual roller 68 is formed of metal while rollers 64 and 66 are provided with outer layer of resilient material, all as well known in the printing art and, therefore, requiring no further description. Ink may be supplied to roller 68 from the box 18 in which roller 68 operates, or in any other suitable way. 7

From the above description it will be apparent that durin the rotation of rollers 14 and I6 they draw the web W therebetween and that while said web passes between said rollers l4 and I6 it is marked and cut into strips of predetermined lengths, the lengths of the several strips being equal to each other and substantially equal to the circumference of roller M. It will be understood that marking members 36 and 38 are moved inwardly against the pressure of springs 48 when each of said members is positioned, during the rotation of rollers l4 and I 6, at the bight of said rollers, it being noted in this connection, that springs I8 are, of course, much stronger than spring 48 and hold roller l4 firmly against the web W or other work which passes between the two rollers. Further, it will be noted that roller l4 can move upwardly, if such movement is required when the work is engaged by the cutting members 56, such movement, if any, being slight so that gears 24 and 26 always remain in mesh.

Thus, the mounting of marking members 36 and 38 for movement radially of roller I4 not only permits said marking members to engage the ink-applying member 64, but also allows for the engagement of the marking members with ttheiwork without subjectingtsaidrmarking membersi toctheqicomparativelyir high pressurefexerte'd on-roller ltbyrSprings 8. "Moreover, in the case of one of themarkingmembersffl, namely the tone at theleft of the cutter member 56' (viewing Figs-4 and the normal' projection ofsaid marking member "outwardly beyond the cutter 'member 56 enablessaid markingmember to engage theend. of the-web immediately after the latteris cut by the cutter memberrfifiand holds .feedingaction of-rollers Mand it.

A chute'BU is provided atthe delivery end of rollers l4 and I6. forguiding the'strips cutfrom the web-W to. a receiving receptacle (not shown). As indicated in Fig.2 .guideSWSZ -are provided on table 8 l, which forms. a part of. frame -lli, for guiding the webs W to the bight between rollers M and I5 and. to thecorrect point. longitudinally of the roller Mlfor engagement in correct relation with the cutter and marking members.

In accordance with the present invention, as indicated above, the present machine .is constructed and operates'to fold a flat webWl into folded form of .the web W illustrated inFigs. 5 and 5A, the latter being-cutinto strips of suitable lengthier makingbandoliers. According- A ly, as here shown, the present machine comprises nleansfor folding the web-WI longitudi- .nally thereof .intothe cross-sectional formation illustrated in Fig, 5A. The means provided-for this purpose comprises a :pair of calender 'rolls 8% and -88 journalled for rotationinbearings formed in a frame member w 95' mounted on 117118 supporting frame it. The folding means -:also

includes a folder .92 of any suitable construction, which many-are -welhknown, through which the flatwveb W! passesand which folds the web into the form illustrated; in --Fig. "5'A,the

calender rolls 8%; and 88 serving 1 -tocrease the folded side edges- 52a andAZblFig. 5A) To 'improve the creasing or ironing effect of the calender rolls, roller 86 is'preferably heated and for this purpose is previded withia gas burner (not shown) dispesed internally thereof, in a wellknown way, andsupplied with :gas through a supply pipe "94. As heated calender 'rolls are well-known and do not per *se form--partof the present invention further description of said-rolls is unnecessary. It may be noted, -however,"that means including a screw-threadedrod'rhifi Joperable by a hand wheel 98*are provided'att'each end of the calender rolls'for-ad'justingthe-ipressure thereof on the folded web'whilethelatter therebetween.

Rollers Stand 88 are driven in timed relation to rollers M and l5 preferably "at such speed that the feed ofthe web 'bylthe calender rolls is substantially equa1"to"the speedof the .webby the rollersltand'lii. Ferthistpurpose'roller i3 is connected to and drives roller 83' by means of sprecliet wheels Hit and Hi2 on the shafts of rollers it and "t5, respectively, said sprocket wheels being connecte'dby a sprocket chain 103. .Calenderroller 85 isdriven from calender roller 38 by the meshing gears IM and" W5 fixed to the shafts of said calender rollers, respectively, there being a set of thesegears atea'ch end of the calender.

Thus, in'the operation of the: machine, one or more flat webs WE are supplied to thewmachine and l are drawn continuously through the folder i9 2 :by .the calender rolls can-d .are;.ironed by ,the

The machine operates continuously tofoldthe webrand'to mark 'and cut the sameall substantiallyrinzone:operation.

It will be understood :that after the strips .are

marked and cut away :from the 'webthey 'are stitched along the lines :marked on saidfstrips andthat-byrreason of :theaccuracy of this machine in locatingthe marked lines'onthe'strips, the stitching of-the 'stripswhen conformed to said :marked lines is "very accurate, this "being very. important :in' the manufacture of numerous articles and especially fbandoliers in which it is important that the pockets formed between successive lil'lESlOf stitching. be of correct width conforming tormilitary specifications.

In Fig, 11" there .is illustrateda modification'o'f the invention. As here shown, provision"v is made l4 since 'by .mOVingfthe cutter member"56 inwardly and outwardly? attheproper .timesduring therotation of roller M, said cutter member will clear the ink-applying roller 1'64 without engagingthe latter and'can'rbeprojected beyond the outer surfaces'of the marking mer'nbersfor engaging" the "web eatthe" bight between the companion rollers. .As illustrated, cutter member has a lowersinclinediedge' )8 which engages the inclined'upper surface I I'll OfTthG groove" 58 so that whencutter-- member 56" is moved 1on- .gi-tudinally-of said groove itis projected radially woutwardlyif moved -to -the right (viewing Fig.

111) .and it is. projectedradially inwardly if moved to the left .(viewing .Fig. :11). Any .suitable means may be provided for thusmoving cutter member 56. in timed relation to the rotation of roller .I4 as,.for example, cams H2 andJM properly "designed as will be readily understood td'engage the adjacent-ends H6 and H8 of cutter memberEB' for-effecting the necessary movements of cutter member 56 longitudinally of groove 58. 'It" will be understood that cams H2 and I M are stationary and are slidably engaged by the ends'llfi and H8, respectively, of said cutter member. Further, it will be understood thatcams- I12 and H4 are the reverse of each other so that one cam allows the longitudinal movement of the cutter member when the latter is acted upon by the other cam for moving the cutter member in" the proper direction longitudinally in the groove 58'.

As indicated above when the cutter member is not movable radially of the roller, the marker members-36' and"'38 are movable radially of the roller- M from projected positions outwardly the cutting edge .of cutter member 56 to retracted positions in whichthe outer surfaces of marker members BBta-nd 3B lie flush with the outer surface ofroller 'l Lzassfor exampleto the position of the" right hand marker member 38 shown in '-Fig "10. lt'will beunderstood that each of the marker members-36 and '38"are moved into the retracted positions atthebight of rollers l4 and H5. 'When thermarker member isnotin the form of the'narrow barillustrated herein but is of substantialwidthg. such: as 'for.exampleaprinting plate, such marker member need not be mounted for movement radially of the roller l4 and. the outer surface of the printing plate can be positioned a short distance outwardly beyond the outer periphery of roller l4 since the pressure between the rollers l4 and I6 would, in that event, be distributed over a sufficient area of the marking member, in this case the printing plate, to prevent injury to such marker member.

It is within the scope of the present invention, however, to mount the marker members for radial movement, as described above, when the latter are wider than the bars 35 and 38 or when the cutter member is radially movable.

While we have shown and described the preferred embodiment of our invention, it will be understood that the latter may be embodied otherwise than as herein disclosed and that various changes in the details of construction and in the arrangement of parts may be made in the present described embodiment. For example, instead of a single cutter member, a plurality of cutter members can be mounted on roller M in equal or unequal spaced relation peripherally of the roller so that during the rotation of said roller strips of equal or unequal predetermined lengths are cut from the same web. Thus, for example, two cutter members can be mounted on the roller in peripherally spaced relation either diametrically opposite each other, for cutting two strips of equal length during one revolution of the roller, or at a different peripherally spaced relation, for cutting two strips of unequal length during one revolution of the roller. Further, it will be understood that the machine can cut and mark materials and articles other than sheet materials or articles formed from material. Also, it will be understood that it is possible to utilize certain parts of the machine without others. Accordingly, we do not wish to be limited to the invention as herein shown and described except to the extent which may be required by the scope of the appended claims,
