22 Claims.

This invention relates to the preparation of laminated products, and moreparticularly those in which a layer of. special surfacing material may be included, so asto obtain a surface hav- 5 ing a special .finish on one side or having ,re-

sistance against particular material with which it may contact. As a further refinement also, such composite sheet material may be formed into structures of tubular character to present a desired facing material internally or externally. Other objects and advantages will appear as the description proceeds.

To theaccomplishment of the foregoing andrelated ends, the invention, then, comprises the features hereinafter fully' described, and particularly pointed out in the claims, the following description and the annexed drawings set-.

ting forth in detail certain illustrative embodi-. ments of the invention, these being indicative 20 however, of but a few of the variousways in which the principle of the invention may be employed.

In said annexed drawings: Fig. 1 is a diagrammatic plan view illustrat- 25 ing the assemblage of a plurality of layers of taken'on aplane substantially indicated by line 5V, Fig. 2; .Fig. 6 is a diagrammatic plan view showing the feed movements between the severing means a'ndthe mandrel; Fig. '7 is an enlarged detail on a plane substantially indicated- -at line VlI, Fig. 2; and Fig. 8 is an end view thereof. In accordance with'the invention, sheet material is laminated together, a special facing layer as desired being assembled with abody layer, and for illustration a web of cellulosic material 45 as supplied from a roll 2, Fig. 1, has an adhesive applied to one surface and is brought into assembly with another web of cellulosic material from a roll 3, the assembled sheets forming a composite, which is then further handled in accordance with the invention. Depending upon may be obtained in the further assembly; and

the composite as formed from the webs from rolls 2'and 3 in glued together relation may be considered as traveling in the direction of the arrow 41, Fig. 1, the composite being then for instance severed into transverse strips 4 which 5 will have the peculiarity of two layers at one end, the under layer as viewed in Fig. 1, being the special surfacing material, which extendsfrom the edge in to the dotted line 5, while the remainder .of the sheet I is of the general body 10 material. As readily seen, various effects may be had, depending upon the particular materials introduced by rolls 2 and 3 respectively. As an illustration, the roll 3 may be of cellulosic material particularly resistant to oils and greases, and the roll 2 may be of cellulosic material of lower grade paper stock suitable for body usage. Thus, the roll 3 may be of oil-proofed paper, hydrated cellulose, parchmentized paper etc., and the roll 2 may be of 'kraft, chipboard, chestnut board or other relatively cheap paper stock. By employing a water-proof material as the stock roll 2,

a water-proof faced composite material may equally well be assembled, as readily seen. And by one roll of facing material on one side having oil-proof properties, and another roll in application for the other side having -water-proof properties for instance, a composite of corresponding respective surfaces may be had. And, byadvancing the sheets 4 for instance in the dimotion of the arrow b to a further laminating means bringing thematerial together in'the form of a wound-up tube, the latter may correspondingly have a-special facing inside or cut,-or both,

as may be desired. The mechanism 'efiecting these functions may vary in its detail, but one desirable form is illustrated, in which, as seen in F g. 3,'the roll'of paper 3 is placed in a suitable framing from which it is fed forwardly, while a roll '2, suitably supported in the framing at a 40 point in advance of the roll 3, is fed to contact one surface with a gluing roller 1 and is then brought together into assembly with the web from roll 3; This portion of the mechanism may involve adhesive applying means including an adhesive supply-pan 8 of suitable character in association with the gluing roller 1, and the web of paper 9 proceeding from the roll 2 passes over such gluing roller and receives an application of the adhesive therefrom, and thence is diverted by guide rollers Ill, II, also passing a doctor scraper 8a, into assembly with the web l2 from the roll 3. Beyond the point of assembly, an adhesive applicator is arranged to apply adhesive across the exposed face of the composite traveling thereunder, and such applicator may comprise a glue-supplying roller .15 arranged to pick up the adhesive from a suitable pan IS in association therewith, and then feed the adhesive by means of distributing rollers l1, It, to the paper traveling thereunder. By mounting the rollers l5, l1, l8, in a pair of arms I 9 which may be pivotally mounted at in a pair of brackets 2|,the rollers may be rocked away from the paper. Such movement may be effected by link 22 and lever 23 and any suitable operating means therefor, such as a cam on shaft 26 to give the small movement required. Conveniently a hold-down arm 230. may also be operated by lever 23 through a link 23b, and thereby the paper is prevented from slipping when a cutter operates upon it. The rollers l5, l1, 18, may be driven through suitable gearing from a sprocket chain receiving its drive in turn from the shaft 26.

Beyond the gluing means" is a cutter, which may be in the form of a knife or rather a pair of knives 30, 30a, Fig. 3a, extending across the width of the composite sheet material and being workable shear-wise by suitable means, as for instance a rack 3|, Figs. 3, 3a, operated by a link 32 through the bell crank lever 34 fulcrumed on the frame at Ma and having its free arm operated by a cam 34b on shaft 26. The severing blades, urged apart by a spring 3Ia between projections on the respective blades,

may be moved together by cams 3lb on cross shafts carrying pinions 3lc operated by the rack 3|, the cams being set appropriately. By cutting the composite sheet material into transverse strips of adapted width 9. suitable dimension thus may be had for further laminating in wind-up operation to the formation of a tubular body. To carry the cut strip for the further operations, a.gripper is provided which is movable to a position adjacent and parallel to the severing knife, the gripper G being suitably mounted to then move in primary path, asindicated in Fig. 6 back to a position remote from the cutter and parallel, and then be moved axially in a secondary-path tocarry the cut sheet into the jaws of the mandrelfeeder'F, which being in a position to receive the end of the cut sheet then moves forwardly to present it to the windup mandrel m, Fig. 2. Thus, as seen in Fig. 6, the gripper G in its dotted line position seizes the web and carries it back to the position at the left of Fig. 6, in dotted line, and the knife means 30, etc., severs the web, then the gripper G moves axially to the full line position shown, whereby the end of the cut sheet is put into the feeder F in its full line position shown, and thereupon the feeder F advances forward to the dotted line position, adjacent to the mandrel, to carry the, sheet to the mandrel-gripper. The S ipper G, Figs. 2, 7 and 8, may involve a movable carriage assembly and comprise a lower jaw ii, an upper jaw 52 movable relatively thereto in gripping and releasing action, and operating mechanism; the latter being of detail as desired. For instance, spring means 53, Fig. 8, at the back beyond the pivot fulcrum of the upper jaw in lugs 54 may serve to close the upper jaw, while a rack bar 55 movable axial-wise of the jaws and carrying inclined wedges a which slide against coacting wedges on the back of the jaw 52 may be provided to effect release. The jaw structure or gripper can slide axial-wise in the guide carriage El and the carriage can slide bodily in frame guide 1. While the gripper carriage is mes es going through its travel movement from the cutter 30 back and across to the mandrel-feeder F and return for a new charge, undesirable prolonged action of the glue roller l8 on the paper is prevented by the roller being raised from the paper bycam 34b, lever 23 and mounting l9, etc. At the same time, the lever raises the holddown 23a so that the paperis'feedably pulled along infeed-movement in timed cycle; and it will be observed that the end of the paper (the cutter 30 being now open), is in position to be seized by the gripper G appropriately and be then pulled out thereby, whereupon the cutter 30 operates again, and the gripper goes across with its cut strip tothe mandrel-feeder F, thence to return to the end of the paper web again for a repetition of the cycle. The movement of the gripper carriage G back and forth in the slide guides ,f is effected in timed relation by suitable means, as for instance the carriage having a rack 56, Figs. 2 and 3, operated by a pinion 51 whose shaft-is rotated' ior movement of: the carriage toward the cutter by sprocket 58 and unwind chain 59 pulled by a tension spring 60, while for reverse movement the shaft of the pinion 51 is turned by gear segment 6| which is fulcrumed at 62 on the frame and its extending arm has a cam follower 63 operated by a suitable cam 64 on shaft 65. The carriage desirably has guide rods 6 slidable in the frame. Movement'of the gripper axial-wise in the carriage is effected by a suitable means, as lever arm 68 having its lower end pivoted and its upper end to be received between idler rollers 81 projecting from the gripper, the leverv arm 68 part of the time resting passive, the timing being such that the end 'of the lever arm 68 is in a position to come between the idler rollers 61 when the gripper is moved from the cutter to its remote position. Reversely, the lever arm 68 is thrown back by thecam 69 and slides the gripper back to a position away from the mandrel-feeder F, and the gripper carriage may then be moved bodily back to the cutter in repetition of the cycle with the lever-arm 68 in readiness for use. In detail further, for actuation of the movable jaw 52 of the gripper, while the jaw-closing spring 53 has a constantly-acting tendency, the jaw-opening in timed relation may be provided by movement of the rack 55 by means of pinion 14 carried with the upperjaw and having on its stub shaft a. crank IS in position to be appropriately turned by tripper-arms I6, 11, these being mounted for suillcient slide movement in slideway 18, Fig. 2, and the tripper-arms being connected to a slide rod 19 having operating lever 13a on a short vertical shaft 19b whose lower end is provided with a cam-arm 19c engaging cam 19d. With this, after the gripper presents its out strip to the mandrel-feeder F, the tripper-arm It is pulled back by the mechanism recited, it having been sufficiently advanced toward the mandrel-feeder F to allow free transit of the gripper-crank l5, and then in such movement in the direction away from the mandrel-feeder F the arm I6 turns the crank I5 and the pinion I4 and thereby moves the jaw-rack 55 to release jaw 52 of the gripper so that the mandrel-feeder F can maintain the out strip. Further movement of the arm 16 shoves the crank I5 and the gripper with it back to position remote from the mandrel-feeder, ready for bodily movement of the gripper carriage G back to the cutter 33. After the gripper has received a new charge and is ready to be returned back away from the cutter, the arm 'I'I comes into operation and in its may set the gripper jaw and hold the cut strip while the carriage is then moved away from the cutter, the cutter being open. Continuing movement of the arm 11 now shoves the crank 15 and grippermechanism in its carriage G forward to position adjacent the mandreLfe'eder 'Reof the carriage away from thef mandrelv feeder is eifected by the cam 69 operating the and s 'gle layer thickness at the other edge, is'advancedfunderthe adhesive applicator l6, l1,

lever 66 through the cam-lever I0 and compensating link I l. The feeder F may involve a pair of fingers 35, 36, Fig. 5, the latter being openable relative to the former, and both being carriedby suitable bracket. means 3T on slide. rodsl36, whereby in retracted position of the finger-carr I ryingbracketmeans- 31, the fingers may. receive f .length,l,th eir, length in this case being transverse of the originally-directed travel of the sheet material, such .dimension, as indicated,, being parthe cut sheet, and carry it forwardlyto the windup mandrel m. The reciprocating movement of the feed fingers may be provided by suitable drive means, such as a lever 39 which may be operated in turn through a slot-wise connection by a link ,46 which is reciprccated by a camll operating on cam- followers 42, 43, on the link. The movable feed finger 36 is opened and closed in timed relation with the movement of the slide, such asto be open at the moment of being in position to receive the end of the cut sheet, that the latter may ride into the opening between the fingers, but on the starting of the return movement of the slide the finger 36 is pressed against the sheet, and from its shape and relative weight, frictionally engages the sheet during the moving in the feed-direction, toward the left as illustrated in Fig.5. Operating means for this may be for instance a pressure arm 36a bearing upon other arm 36b extending angularly, pressure may normally be'applied to the feed finger 36, but on periodic engagement of the arm 361 by a release lever 360 the holding pressure on the feed finger 36 may be momentarily released to allow feed of a fresh sheet inappropriate timed relation. with the lever 36c fulcrumed at 36d, its movement may be controlled by a link 44, pulled down by cam operating against cam-follower 46 on the link, while the. reverse or raising movement Y may be accomplished by tension spring 41 extending from the link 44 to, a fixecl point, on the framing. If-the feed finger 36 be a pair of feed' fingers arranged side by side, as shown in Fig. 2,

two strips as split by a s l'itter i49-maybe fed to .the mandrel m simultaneously and two tubes may be wound up atthe same time, instead of one, if preferred- Arrived at the wind-up mandrel m, the timing issuch that the latterpresents open gripping means ready to seize the advance end of the sheet. Such gripping means may comprise gripper elements having intermeshinggearteeth, and driven through intermediary gear elements from anaxially-extending"internal stem which at its outer end receives'interrnittentmotion oscillatingly 'at appropriate timed intervals to open and close the gripper elements.- An advantageous construction is set fortl'r'in' detail in' my copending applicationSeruNo. l60,029,..filed August In 'the operation of making up a laminated ticularly detailed here.

'1, is brought into contact with the sheet material from the stock roll 3, and if the width of the latter is greater than thatof the former, as is desirable in the case of makingup composite sheet material tobe further laminated into tubular bodies such as to give a special lining,

the assembled material .now inthe stage of .two ,layer thickness atone edge,.as,seen in Fig. 1,

l8, and elves a coating of adhesive on the a e opposite from the special surface ence proceeding to the cutter 30, the

po e heet material is cut into strips, which are relatively.narrow' as compared with their ticul'arly; suitable for feed to a tubular winding- .iip mandrel, and to this end,the cut strip is carried by the gripper carriage G to the feed fingers 35, 36, which'then carry it into the" gripper jaw of the mandrel m suitably positioned at thatmoment, and the latter in its rotation winds the strip over and upon itself, the special facing layer being internally against the mandrel surface, while the adhesive-coated surface is' on the outside and thereby the successive layers as laid on are joined v together into 'a" laminated tubular structure. Further compacting may be had if desired by a pressure roller which may be springtensioned against the mandrel and material thereon. At thevcompletion of the winding operation, a slide-collar 80 pushes the woundtubular body axially along the mandrel one step, in order to clear the mandrel for the next oncoming strip to be wound. .The collar 80 may be reciprocatively moved by any suitable means, for

instance a cam and lever and link connections to a slide carrying the collar, as need not be par- If desired, the tubular body may be further surface-finished exteriorly by application of a cover layer, or the surface may be treated by liquid, or both, in accordance with particularly-desired character and intended usages.

As a'further refinement, in assembling the sheet material from the stock-roll 3',with that from the stock-roll 2, it is advantageous in some instances to so relate the respective layers that a special surfacing layer fromthe roll 2 slightly extends beyond the margin of the sheet material from roll 2, as indicated in dotted line at the lower edge of Fig. 1. Then, in being directed into assembly with the web I2, such projection in the margin is turned up and over in traveling against a suitable guide 86, Fig. 3,"and is flattened into place by ninningunder smoother i and is pasted down, covering and guarding the winding-up starts on the mandrel, is such-"that there is no possible exposure of the poorer body 'stock'la'yer, but-only-thespecial liner material is in exposure, and thereby when used as' a-con-' tainer, with suitable-closure heads, liquid contents as for" instance oils, may be-excluded from working into the backing layers by any possible exposure of, unprotected material, 'even" in "very slight extent, at the seam.
