of each group are secured to each other along'an edge which is at right angles-to the edges of the exposed portions. The number of sheets in a group may be varied to'fit the particular purpose 15 for which. the sheets are used. The sizes of thev sheets may be varied., also.

The present invention has for its principal object 'the provision of an .apparatus and method whereby units composed of a plurality of sheets may be rapidly assembledfrom webs of paper or like material as a continuous process. The invention contemplates the assembling of a plurality of webs from suitable spools into overlapped relationship, the securing of the webs together at longitudinally spaced intervals, and subsequent cutting of the webs along lines adjacent to the points of securement so that each cut will `produce a unit strip comprising the several sheets in overlapping relationship.

It is also a purpose of the present invention to provide a sheet assembling apparatus of the character described wherein a no vel means is employed for securing the several sheets together, the novel means comprising an adhesive apply'- 35 ing device adapted to apply adhesive to the sheets in small areas or dots which are placed adjacent to one edge of the sheet and are spaced from each other lengthwise of the edge.

It is a further purpose of this invention to provide a machine of the character described lwith means whereby adhesive material may be f applied in rows extending transversely across the webs which are assembled, the rows being A spaced uniformly lengthwise of the web. In this connection, the invention contemplates an adhesive applying device having vfingers, which .are adapted to engage the web at spaced points along a line extending across the web and means are -provided whereby the operation of the'fingers is 50 timed to occur while the web4 is stationary.

More specifically, it is the purpose ofthe present invention to provide a sheetassembling apparatus wherein the several webs are supported andguided into overlapping relationship so that (ci. zic-sz) a portion of each web is exposed when the eral webs are brought into engagement with each other, together with .means for applying an adhesive between the webs before they are brought into overlapped relationship, and means for cutting the overlapped webs to provide units -of sheets.

The features and advantages of the present -invention will appear more vfully as the description proceeds, reference being had to the accompanying drawings wherein a preferred form of the invention is shown.

. of the frame 28 carries a spring pressed bearing pin. 88 which is adapted 4to engage in a conical seat 48 in the end of the shaft 28. The bearing pin 88 is housed in a shell 4| that is ilxed to the Fig. 21 is a fragmentary plan view-.of anl` assembled unitcf sheets such as are'produced by the present apparatus and method.

Referring now in detail to the drawings, andparticularly to Fig.- 21, there is lshown inthis figure a plurality of'sheets 22 which sheets are arranged' oneupon the other in overlapping relationship so that a portion 23 of each sheet is exposed. 'Ihis portion of the sheet is adapted to receive a legend such as a line of printed It will be evident, of course, that the width of the exposed portion 28 will of neces-I i sity be different for different uses of the unit of sheets, and the size of each sheet inthe unit may be different for different purposes. The several sheets 22 are adaptedto be secured together along their side edges 24 Vby applying an adhesive material 25, such as glue.. between the several sheets. This adhesive material is preferably applied in small areas along a line adja cent to the edge 24 of each sheet. The small areas 25 are shown in Fig. 21 as'being arranged in a row running lengthwise. of the edge 24, the

several small areas or dots being spaced apart uniformly.

The method of making the unit strips from the sheets 22, as lspeciflcally'shown in the present application, comprises .the supporting and guiding of a plurality of webs of paper or like sheet material so that the several-webs are placed one upon the other with a longitudinally extending portion ofeach web exposed'. The several. webs receive transversely extending rows .of the small areas of adhesive 25 before they are brought into engagement `with each other. The adhesiveis applied to the undersurface of each web except the bottom web. This web adheres to .the next web above it because of the adhesive on the lower surface of said next web.' The rows of adhesive areas'are spaced at uniform distances lengthwise of the several webs so that when the webs are brought together the rows of adhesive arel superposed. The several overlapping webs arefad-` form'the unit strips.

In Fig. 1 there is-shown a web supporting y frame 28 having a multiplicity of web carrying spools 21 removably mounted therein. 'Ihe construction of the spools is that'shown in Figs. 16 and 1'1. A shaft 28 -has a -longitudinal key-way yof the adhesive container 54.l

28 thereon. A plurality o f discs 88 and 8| are keyed to the shaft 28 by` keys 82 and 88. Between the discs 88 and 8| a webA carrying sleeve 84 is rotatable upon the shaft 28. 'A collar 85 acts as a shoulder to limit the endwise movement of the disc 88,'while aspring and a collar .81 arearranged topress thefdisc 8l toward the disc 88. Y,The pressure-'of the spring 88 is fairly light.'l but Y is sufilcient to snugly hold the discs against the Aweb retaining sleeve 84. It-will be understood -that it is a simple matter to replace a web by removing one ofthe discs 88 from the shaft 28 and threading a new web carryingsleeve .uuponthe shaft is.

The shaft- 28 is removably mounted ln'the frame 28.

It has a pin 88 engaging in an openframe 28. The pin 88 has a groove'42 therein; and a screw 48 in the shell 4I rides in the groove 42 to limit the outward movement of the pin 88.

Thepin 88 has a reduced shaft 44 which pro` jects through the end of the shell 4I.

v A spring 45 is seated in the shell 4i so as to pressv the pin 38 outwardly.

Referring now to Figs. 1 and 1l, it will be noted that from the several web supports 21 the webs are carried forward over suitable guides in the frame 28, and threaded between a multiplicity of guide rods 48. The guide rods 48 are mounted upon and extend between two semi-circular side . frame members 41 and 48 of the frame 28. It

will be noted 'from Fig., 1 that the several rods 48 are so arranged with respect to the approachingl webs that all of the webs bear on the lower surfaces of the rods. This is for yconvenience in placing the-V webs at the vdesired position. It

will also be observed from Fig. l1l that the several web supports 21 are so positioned endwise the brackets 48 is preferably aligned with' one 35 ofthe discs 8| of the several web supports. The

collars 58 are set to align with the discs88 of ship so as to give the'desired amount of exposed portions 23 on the ultimate sheets.

v'I'he brackets 48 and 58 are each adapted to removably support an adhesive container 54 (see Figs. 14, 15 and 20).I The containers 54 seat in recesses 55 and .'58 which are cut in the brackets 48 and 58. fEach container has a concave socket 51 adapted to receive a pointed screw 58 that is threaded in the bracket 58. A thumb screw 58 is threaded in the bracket 48 and has a pointed end adapted. to engage in a similar conical socket .88 provided in.the adjacent end (Each container 54 has an opening 8i in the top thereof and a rock shaft,v 8,2 is journalled in the ends of the container 84. This rock shaft carries a pluralityl A of fingers 88 which are adapted to swing between a position shown in full lines in Fig. l5 within the adhesive material in the container 54 to a will beounderstood that there is a lever arm 81 and a rock shaft 88. foreach ofthe pairs of brackets" 48 and 58. The rock shafts 88 are rotatablyjournalled in the brackets 48 and 88 and in the Viside frame members" and 48. By

actuating the rock shafts 88. the ngers 88 'are causedto alternately' dip into the adhesive ma- I terial in the containers 54 and move up into- 4 l `position to engage thewebs' which pass beneath ing in one side of the frame 28. 'Ihe other side 15 the 48. Y l

thereto adjacent the shaft 84. These yracks mesh with two gears 88 and 88a. which are carried by the frame 26 there are two rubber covered guide vrolls 13 and 14 to which all of the webs are led after they pass from the rods 46.v These rolls are adapted to press theseveral webs tightly together in overlapped relation. The rolls 13 and 14 alsov act to force the adhesive between the webs into the material of the webs and to spread it. This prevents the adhesive carrying parts of the overlapped webs from becoming excessively thick as compared to the combined thickness of the webs, where there is no adhesive between them. yThe rolls 13 and 14 are approximately at the center of the circular path in whichv the adhesive applying fingers lie.

The several webs, after being placed in overlapped relation, pass between two web advancing means 15 and 16 whichv supply the necessary force to pull the several vwebs from their supports-and through the path `just described.

The means 15 and 16 are supported by a plurality of standards 11, 18. and 19, the standards being connected by three tie'rods 19a,.19b and 19c. These standards-also lsupport; a guillotine shear 80,. a unit lifting and removing suction mechanism 8| and the driving mechanism for the machine, including a drive motor 82. Before explainingthe detailed operation of the advancing means 15 andv 16, the driving mechanism for the several parts of the machine will be explained.

The motor 82 has a pinion 83 which meshes with a gear 8.4 upon a shaft 85. The shaft 85 is journalled in the standards 11 and 18 and carries a small pinion 85 adjacent the standard 19. This pinion meshes with Va gear 81 upon a main operating shaft 88 that extends from the stand-A, ard 11 to the standard 18 and is journalled for.

rotation in the three standards. The shaft 88 carries a pair of cams 89 and 88, which cams are adapted to control the operation of the shear 80. The shaft 88 also carries an eccentric 9| 'which is adapted to control the operation of. the suction mechanism 8|. l yond the standard 18 andat its outer end has The shaft 88 extends bea shaft 88 that has a hand wheel |80 thereon. The shaft 89 is journalled in the lower web advancing means 16. The shafts 83 and 84 have sprocket wheels |8| and |02 thereon, there being three sprocket wheels for each shaft, one at each end thereof andl one adjacent to the cross bar. 96a. The several sprocket wheels are engagedv by three sprocket chains |03,|04 and |05. The chains are connected by al plurality of separate cross rods |08 so as to form a conveyer structure. lA plurality of chain guide bars |81 are carried on the bars 85, 86 and 86a. As the conveyer structure passes beneath the framework composed of the shafts 83 and 84 and thebars 95, 96 and 96a, it is directed by the guide bars4 |01 gradually downward from the point where it leaves the sprocket wheels |82 and then in a provided for holding fa plurality of sprocket ily attached to the machine so as to double its capacity. ,All'of the operating'mechanism carried by the standards'11, 18 and 18 isso arranged to operate the same, whether the machine is asshown in Fig. 2 or is of the double capacity type.

Referring now to the 15 and 16l and the means for operating the same,

. the "web,l advancing means 15 comprises two spaced shafts 9,3 and 94 which are connected together by three bars 85, 96 and 96a. The bars 95 and-86 have lifting racks 91 and 91a pivoted web advancing means straight line to the point adjacent the shaft 93 where it leaves the guides |01 and is directed upwardly. 'The several cross rods |86 have rubber coverings |88 thereon, these coverings beingrubber tubesl which are slightly stretched when they are placed upon the Vrods |86. The rods are connected to the chains.|03, |04 and |05 by a plurality of brackets shown best in Figs. 9 and 10. The brackets comprise special links |09 for the chains, which links have extensions ||8 bent horizontally beneath the chain and riveted to the rods |06, the rods being cut away, Aas indicated at,` ||I, to provide flat surfaces for the extended portions ||0 of the links. which control the direction of the chains |03, |09 and |85, are bolted to their adjacent cross lbars 95, 86 and 88a by bolts, one of which is shown in Fig. l0 at ||2. 4 n

`The means 16 is substantially a duplicate in construction of the means 15 with the exception that it is stationary. The means 16 comprises two shafts ||3` and ||4 connected by three cross bars similar to 95, 96 and 96a. Only one of the cross bars I5 is shown in the drawings, since the others are hidden by the corresponding cross bars of the upper means15.' Suitable guides |.|6 are chains i|1 exactly like the chains |03, |84 and in proper opposed relation to the chains |03,

|84 and |05. The sprocket chains ||1 are connected by a plurality of cross rods |24 that have rubber vcoverings |24a like the coverings |08. 'I'he means 16 is supported from the standards 11 and 19 by two horizontally extending extensions I I8 and I9 ofthe standards and by two brackets |28 and |2| which are carried -by the extensions ||8 and ||9. The' shaft 3 is journalled in the standards 11, 18 and 19 and is adapted to be driven by the arm 92 through a suitable mechanism to be described. The shaft 93 also extends through the standard V19l and is journalled in the standard 18. The two shafts 93 and ||3 are connected together by two gears |22 and |23 (see Fig. 4).

The function of the rubber covered cross rods |06 and- |24 is 'to grip and move the several overlapped webs step by step to the shear 80. All of the advancement of the Webs from their supports 21 is caused by the step by step advancement given the overlapped webs by the rubber covered bars |86 :and |24. It is highly essential that this advancement be accomplished without in any way disturbing the overlapped arrangement of the several webs,l since uniformity and The guide bars |01,

'i 08 and |24 also serve to apply pressure to the overlapped webs suicient to causethem to adhere rmly to each other at the points where the adhesive is placed 4between the webs. It has been found necessary, in order to Iavoid slippage and" distorted alignment of the webs, to have the rods |08 and |24 brought gradually into engagement with the webs. This isfaccomplished by the guides |01 and ||8 which are soshaped as to direct :the chains toward each other along gradually approaching lines.` Since the overlapped webs are always engaged by several lpairs of rubber covered rods, there is no opportunity .-for relative slipping, and the yielding of the rubber is sufficient to accommodate the irregularities due to the overlap.

Rotation of the shaft ||3 and t-he shaft 83 is accomplished by the mechanism shown most clearly in Figs. 4, 7 and 8. A rack |25 is mounted on an arm 82 by means of a clevis |28 which is pivoted about a bolt |21. `The bolt |21 is thre'ad-v ed to receive an adjusting screw |28'which is i carried in a-slot |28 of the arm 82. Rotation of the screw |28 is utilized to adjust the position of the rack |25 lengthwise of the arm 82 and to thus control the stroke imparted |to the rack |25. The rack |25 is adapted to mesh with a gear |30 (see Fig. 7) which gear is iournalled on the shaft H3. A sleeve |3| is interposed between the gear |30 and the shaft II3. The gear |23 which is keyed to the shaft ||3 abuts 'the gear |30.

The gear |30 has a hub portion |32 which ex-` tendstoward the free end of the shaft ||3 and has an enlargedvannular head |33 thereon. The annular head |33 surrounds a clutch member |34 that lis keyed to the shaftA I I3 by a key |35. A. cover plate |38 is mounted over the open end of the head |33. The member |34 has a reduced extension |31 which projects through the plate |38, the reduced portion, of course, being cylindrical. The head |33 and the member |34, to-

gether with a plurality of spring pressed rollers |38 and notches |38 in the member |34, constitute what is usually termed an overrunning clutch or one-way drive connection between the head |33 `and the member |34. The head |33 is, of course, oscillated by reciprocation of ,the rack'l25 in engagement with the gear |30. The head |33 is therefore the driving element which, when movedin the direction indicated by `the arrow in Fig. 8, causes rotation of the member |34 and the Yshaft I3. When the head is driven in the opposite direction, the rollers |38 recede toward the deeper portions of the notches |38 and the head is rotated on the. member |34. In this way, step by step movement is communicated to the shaft ||3 and through the gears The Shafts sa and ns drive the web advancing mechanism comprising Ethe means 15 and 18.

there is mounted a cutter bar which removably supports a movable knife |45. The knife |28 is secured to the ba-r |45by suitable screws 1. bar |45 alongside the knife |48, these pins being spaced at frequent intervals lengthwise 0f the bar. 'The pins |48 terminate somewhatabove the cutting edge of the knife |48, as shown clearly in Fig. 5. The standards 11, 18 and 18 have guide grooves |48, and |5| respectively for receiving the bar |45 Vand guiding it in its vertical reciprocation.

Suspended from the bar |45 by a plurality of bolts |52 is a presser bar |53 which is adapted to -engage severed portions of the overlapped.

webs as the bar |45 descends. The bolts |52 are slidably mounted in the bar |45, as shown in Fig. 6 at |54. A plurality of springs |55 are interposed jbetween the presser bar |53 and a ledge |58 provided on the bar |45. When the bar |45 f is pressed downwardly, the bar |53 at first moves down with the` bar |45 until it engages the top of the plate |42. Further descent of lthe bar |45-then results in compressing the springs |55 as the'kniie |48 is moved by the bar |45 to shear the webs which are fed across the base plate |42. As the cutting stroke of the knife |48 -continues. .the pins |48 come into engagement with a supporting plate |51 which is mounted on a plurality of pins |58 that are slidably mounted in the base plate |42. 'I'he pins |58 have coiled springs |53 thereon which normally holdfthe plate |51 in its raised position. The base plate |42 has arib |80 thereon/through which the pinsf|58 extend. i

The bar |45 is adapted to be operatedlby the cams 88 and 80. A shaft |8| is mounted in the'standards 11, 18 and 18. Adjacent the' standqard 11 the shaft |8| has an arm |82 pivoted thereon. This arm carries a roller |83 which engages the cam 88. At its free end, thearm |82 supports a rod |84 which extends through a slot |85 in the standard 11. Outside the standard 11 the rod |84. which is rotatably mounted .in the arm |82, connects with a rod |88 which is secured toone end of -the bar |45.

Adjacent to the standard 18, the shaft |8| has a lever arm |81 pivoted thereon. This lever arm carries a roller |88 which is adapted to engage the cam 80. The .rod |84 extends through the lever arm |81 and through a. slot |88 provided in the standard 18. A rod |10 connects the rod |84with the end of the bar |45,-as

. shown best in Figs. 3 and 4. The rodl |84 1s |13and |14 tothe base plate |42. When the The degree of advance imparted .to the webl is controlled'by adjusting Ithe effective length of `the rack is adjusted by means of the screw |28.

Referring' now to .thefshea-r 80, the construcf non' of the shear 1s shown best in Figs. 3-6 inelusive. The .shear comprises a base plate |42 which is carriedby the standards 11, 18 and 13.

cams 89 and 80 engage the rollers |83 and |88 with their extended portions, they push the. levers |82 and |81 downwardly so as to move the rod |84 downward against the tension of the springs |1| and |12. This lowers the cutter bar |45 so .as to cause the knife |48 to cut the overlapped This base plate mounts a stationary knife |43 webs which are fed across the plate |42.

The lever |82 also -operates the adhesive ap/ 12a and 12b, as shown in Fig. 6, these sections being overlapped and held by' two collars` |18 A plurality of pins |48 depend from the roller being mounted upon air cylinder and |91 on the link |94,

-An additional valve 'the arm |92.

i are] advanced each step in order tov have the and |19` which are fastened by two screws |80 and |8|. It is thus possible whenever desired toadjust the length of the bar 12.

The shaft 88 is adapted, through the eccentric 8|, to actuate the suction device 8|. The eccentric 9|` engages-a roller |82 (see Fig. 5), the an arm |83 which is formed on a lever |84.A The lever |84 is rotatably mounted on the shaft |6|. At its upper end, thevlever |84 has a piston rod |85 pivoted thereto. |86 which operates in an air cylinder |81. The |81 is carried by the standard 19. |88 for the cylinder |81 is conhose |88 to the suction An inlet pipe nected by a flexible air device'8l.

An exhaust valve |90 is mal exhaustion of the cylinder |81 as the piston moves toward the closed end of the cylinder. |'9| is provided for admitting to break the suction sud- |89 at the proper time. The

air to the cylinder denly in the conduit valve |9| is carried by an arm |92 which is'pivotally supported by a bracket |93l that is mounted on the standard 19. The free end of the lever arm |92 supports a link |94 which has an elongated slot |95 in the end thereof remote Afrom The arm |92 and the link |94 are loosely connected byV means of Ispaced collars |96 the link, of course, being extended through an opening in the arm |92.` The link |94 is secured to the lever |84 by a headed pin |98 which extends through the slot |95. The lost motion provided by the slot |95 allows thelever |84 to draw the piston |86 rearwardly far enough 8 I, but just before the lever .|84 reaches its limiting position, shown in dotted lines in Eig. 5, the pin |98 engages the outer end of the slot |95 so as to pull the 'link |94 to the left and thus open the valve |9| and release the suction in the conduit |89. The lever |84 and the pin 98 also actuate an` arm |99 which is fixed on a rod 200 by a pin 20|. A spring |99a tends to pull the arm |99 into the position shown in full lines in Fig. 5. The pin |98 engages the arm |99 near the end of the suction stroke of the lever |84 and moves the arm |99 to the dotted line position shown in Fig. 5. The rod 200 extends lengthwise of themachine and is supported by suitable lugs 202-provlded on the standards 11 and 18. Two links 203 and 204 arexed on the rod 200 and at their upper ends are connected to horizontally running levers 205 and 206. The levers 205 and 206 are upstanding posts 201 and 208 which are provided on the standards 18 and 11 respectively. k The levers 205 and 206 carry the suction device 8|. The suction device pipes 209 and 2|0 which -are connected together at the center by connecting piping 2|| which also is connected to the flexible conduit |89. xThe pipes 209 and 2|0 carry' a plurality of suction nozzles 2|2 (see Fig. 3) each of which is provided with a valve 2|3. The nozzles have rubber tips 2|4 which vare adapted to engage the overlapped webs and slide :them off of the plate |42 onto a conveyer 2 l5 (see Fig. 4)

Means are provided to adjust the frame 26 towardv and away from the web advancing means and 16 vto accommodate the apparatus to the making of different widths of unit strips. It is necessary that the distance from the adhesive applying means to the shearing means be a multiple of the distance' the overlapped webs The piston rod |85 carries a piston slidably supported by 8| comprises two provided for the norto actuate the suction device eral webs into overlapped other, the cutting of the overlapped webs, and

'ard 11. I-t has a ing with a worm -side portions 2|9 and adhesive on the overlapped webs occur at the proper place on theunit strips.

The trarne `adjusting means includes a U- shaped framework' 2|8 which is adapted to receive the brackets 26a and 26h on the front of the frame 28. The frame 2|8 and the brackets 26a and 26h have openings therein to receive two pins 2|1 and 2|8; The frame 2|6 has side portions 2|9 and 220 which are adjustably secured to the standards 11 and 18 and which may be moved together to move the frame 26 to and from the standards 11 and 18. A shaft 22| extends between the standards 11 and 18 and is journalled in bearings 2.22 provided on the standards 11, 18 and 19. A screw threaded shaft 223 v(seel'ig. 6) is journalled in the standworm gear 225 on the shaft 22|. Also, a screw threaded shaft 226 is journalled in the standard 18. It carries a worm gear 221 which meshes with a worm 228 on the shaft 22|. The 220 are connected to two screw threaded blocks 229 (see Fig.' 18) which receive the screw threaded shafts 223 and 228.

The shaft 22| has a hand wheel 230 thereon. The frame-26 is adjusted with respect, to the web advancing means by turning the hand wheel 230 and thereby rotating the shafts 223 and 226 to move the blocks 229 endwise of said shafts.

The general operation of the apparatus .which has been described comprises the loading of the frame 26 with necessary spools of paper, the setting of these spools so as to give the proper overlapping of the webs as they are brought together, the application of the' securing means (adhesive) to the webs, the bringing of the sevengagement with each the removal of the unit strips cui? from the webs.

capacity of the apparatus may be fed to the adhesive applying means. I f some of the adhesive applying devices are not to be used, they may be removed frorn 'their supports.

All of them are easily removed for cleaning, fillpossible to use the apparatus same width because all of the. webs are advanced the same amount. f

It is desirable to have two frame is loaded with spools and adhesive material while the' other is in the process of making unit strips. For the maximum capacity of the machine shown there should be four frames 26' and two sets of advancing means 15 and 18. The one shear and the one suction device can take care of the webs advanced.

It will be noted that the parts are arranged so that the adhesive is applied while the webs are stationary. Thus there is a clean cut row of small dots or areas of adhesive between each pair of adjacent sheets in a unit strip. The' advancing means 15 and 16 have their cross bars oppositely disposed and close together so that 224 thereon mesh- It will be appreciated' that as many webs as.
