' Harmon ,or AND MACHINE Fon MAKING LAMINATED Drums.

, Application lled August 31, '1921, Serial No. 491,211. Renewed April 1Q, 1926.

'lhis ,invention relates to a method of and machine for winding'and forming laminated drums, particularly paper drums, which may be used in containersof cylindrical or other hollow form.'

An object of the invention is to provide. a machine in which the paper will be wound true in the form of a drum without the need of any further adjustment than the initial adjustment of the laminated material on the machine.

Another object resides in the provision of means whereby adhesive is constantly and uniformly applied between the layers or laminations and an outside surface suitably coated with 'the adhesive, which maybe a waterproof material or not as desired.

A further object resides in the provision of means whereby the pressure applied to the material being wound is regulated in a predetermined manner and thereafter operates automatically .in-proportion and in accordance with the'variations of working conditions in the machine.

Another object resides'in the provision.

of means whereby drums of different diameters, lengths and cross-sectional shapes, may be readily .wound on the one machine, and whereby to change the parts of the machine to laccommodate one drum' or another involves a minimum expenditure of` time and labor.

A further object resides in the provision of means whereby after a drum has been wound and formed it may be very' readily and quickly` removed from the machine.

A still further object resides in the provision of means whereby the application of adhesive to the selected parts of thematerial on the winding drum can be achieved.

Another object resides in the particular construction and arrangement of parts which are hereinafter described and claimed and shown in the accompanying drawings.

It has been found that in winding and forming cylindrical laminated fabric'drums by machinery', the fabric having once been disposed accurately in the machine will not necessarily be wound accurately and true un,- less the application of pressure on the fabric as it is being wound on the winding drum,

so that in .effect the linear speed of the adhesive pressure roller is the same as the linear` speed of the winding drums with -whichit is in contact. It is to 'be understood that in this 'machine the proper function of the pressure roller is not only to reguf late the thickness of the adhesive on the -winding drum but also .to insure thei true rolling of the paper or fabric. In other words, the adhesive may be actually applied to the winding drum by some .other means than through the medium of this roller with. out departing from 'the spirit of the invention.

Itv has been found particularly needful tov the success ofthe operation of this machine i that the 'flexible ,characteristics vof the adhesive regulating and pressure-applying roller should be such that the roller not only can be brought into heavy pressure contact with the winding drum but also that the adhesive roller be so flexibly mounted that its axis can assume .angular positions with` respect to the surface lineand axis of the winding drum. By thus permitting either end-of the adhesive roller to yield in accordance with the overcoming of regulated and predetermined resistance, an automatic and accurate allowance for the above-mentioned variable characteristics of the adhesiveand theI paper' is made,whereby the paper will run. absolutely true at the edges and will, therefore, not necessitate trimming, and the adhesive will be applied regularly over the entire surface between laminations. This is true even though the collapsible winding I .of a bell crank lever pivoted at 23.

drum may not be in exact and true circular form or not exactly trueon its outside surface, due to the collapsible mechanism and to the method of supporting the winding drum at one end only.

The invention is illustrated in the `drawings of which- Figure 1 is a plan view of the machine;

Figure 2 is a front veleyation;

Figure 3 isa side elevation;

Figure 4 is an end view of the winding drum;

' Fi ure 5'is a sideelevation of the winding rum;

Figure 6 isa side elevation of another end of the winding drum;

Figure 7 is a detail view of the winding drum showing the auxiliary winding surface applied thereto; and

Figure 8 is a diagrammatic perspective view of the machine.

As shown in the drawings, the preferred formof the invention comprises a machine having a base or bed frame 1 with vertically extending supporting members 2, 3 and 4 and horizontal top frame members 5 and 6. These members may be of any material and any shape, the proportions and dimensions of this frame being a matter of good mechanical design rather than being an essential part of the invention.

On this machine I provide a winding drum 7 on which any suitable laminated material 8, such as Lpaper, can be wound to form laminated drums. This winding drum 7 is mounted on the end of a-'shaft 9 which is journalled in bearings 10 and 1,1 on the frame members 2 and 3. It will be noted that the shaft 9 extends across the top of the frame and'that .theright-hand end of the winding drum, as viewed in Fig. 1, is free, so that the drum 7, by means not shown, may be drawn or taken off of the shaft 9 as desired. lThis provides ready.v

means for replacing one drum with another when necessary. On the shaft 9 is provided a gear 12 keyed thereto. This gear is adapted7 to mesh with another gear 13. This gear 13 is mounted loosely on a shaft 14, the shaft 14 being suitabl journaled in brackets 15 and 16 attache to the frame members 2 and 3. nA clutch member 17 is keyed to the operated by a suitablev connection with a' lever 19 pivoted at 20 on the frame member 2 and at its lower end connected'to a link 21 which in turn is.connected to one endri2l2 e other end 24 of the bell crank lever is provided with a foot pedal 25 whereby the pedalk .when depressed will cause the engagement of the clutch membe'rs 17 and' 18, and may be locked in the operating position under a latch bar 25.

Keyed to the shaft 14 I 'also provide a gear 26 which meshes with a pinion 27 on the shaft 28. This shaft 28 is journaled in brackets 29 and 30 connected to the frame members 2 and 3. The shaft 28 is provided with a pulley 31 keyed thereto. A belt 32 .connects the pulley 31 with a small pulley 33 on the shaft of a motor 34. This motor may be suitably mounted on channel bars 35 and 36 and in any desired mannerconnected to the frame members 2 and 3.

On the 'shaft 14 to the right of gear 26 I provide a pulley 37 over which a belt 38 is disposed. This belt connects with another pulley 39 mounted on a hub 40 at the other end of which is a sprocket 41. Over this sprocket extends a chain 42 the other end of which connects with a larger sprocket 43.

-This sprocket 43 is mounted-on a shaft 44.

This shaft is journaled in bearin blocks 45 and 46. Between these journale boxes an adhesive and pressure roller 47 is disposed. The hub 40 is mounted loosely for rotation on a crossbar or shaft 48 which is journaled in suitable brackets inthe frame members 3 and 4. Between the frame members 3 and 4 a pair of bearing brackets 49 and 50 are attached to vertical bars 51 and 52 and have apertures through4 which shaft 48 extends and on which shaft these vertical bars and brackets are free to move. In Fig. 2. the small pinned sleeves 49 and 50 fastened to shaft 48 are placed in their proper position` shaft 48 extends, and at their upper en'd are suitably connected with pivoted'bearings 45 and 46' to the bearing blocks 45 and 46 supporting the shaft 44 and the winding drum 7. These vertical bearings on which the bearing blocks 45 and 46 rest are necessary to prevent cramping of the ends of shaft 44 in the blocks when .A one end of the roller 47 moves back independently ofthe other. The lower ends of the bars 51 and'152 are connected respectively and separately to springs 53 and 54. These springs at their other ends are connected to a common actuating bar The adjustment of the springs 53 and 54 vmayV be accomplished by means of winged nuts 56. 'A connection or cable 57 is attached t0 the bar 55 and extends over pulleys 58 and 59, and at its other end is connected to the Aupper end of a portion 53 of a bell crank lever 54. This bell crank lever 54 has on vits outer end a foot pedal 55 which is also adapted to be hooked on to the latch 25.

in Fig. 8, therefore, whenever the :foot pedal is depressed the clutch member 17 is moved into engagement with the vclutch Lnember 18 and at the same time, if the depressed, a bar pedal is Simultaneousl i5 is pulled back against t e bracketsGO and 51 which are mounted on theframe.

In the operation of the device the oper-4 ttor, by depressing the pedal 55 will force :he roller 47 against the drum 7.. If the operator finds that the paper is rolling true, ao adjustments are necessary. If the `op zrator finds, however that the paper is running olf true, to one side or the other. he can properly manipulate the wing nuts 56 connected to the springs-53 and 54 so as tollin- :rease or decrease the pressure applied tothe ands of the roller 47 and as-this pressurev is ncreased or decreased the paper, if it is rollng off true, can be brought b-ack to roll true.

With regard to the theory upon which the pressure roller operates across the mandrel 1nd the ibre which is being wound up into i drum, my conceptionof the theory is as follows: `When a roller of material is being wound into a shell under the pressure sys- 3cm, whereby the shell is `wound over a manirel under heavy pressure, andthe slightest difference in the thickness of the fibre across :he sheet will cause the thickness of the .aminated shell at. one edge to be greater than it the other, thus causing the fibre towind iff. With my invention, whereby the pres- ;ure along the surface of contact between the )ressure roller and the mandrel can be reguated, it is possible to reduce the pressure where the fibre is thinner and increase the pressure where the fibre is thicker. This ac- ;ually compresses the fibre at the points where the pressureis greater and simultaneijusly reduces the thickness of the coating of idhesive. There the pressure is lighter the ihre is not compressed and simultaneously a ieavier coating of adhesiveis allowed to Flow between the laminations, tending to swell the fibre. The combination o f these :onditions can, by the proper regulation of :he pressure, cause the laminated shell, even lnder heavy pressure, to beof exactly the same thickness throughout-7 thereby causing t to roll true with clean uniform edges.

The clutch member ,17 is held normally Jut of engagement with the clutch member 1 8 by means of a spring 62, and the barsil fonsequently, the adhesive roller 47, turned oack away from the winding drum 7 ,by means of springs 63 and64.-

A U-shaped metallicframe 65 is rigidly.

connected at one end to the bearing blockl 46 in any suitable manner, and at the other end is adapted to be looselymounted on the 'shaft 44, adjacent the bearing block 45 to permit of relative movement between this end of the frame and the bearing block 45. Thisframe has a portion 66 extending rearwardly along the edge of the adhesive roller 47- but spaced therefrom. Supported ofrom .this frame 65 are adjust-able blocks 67 and 68 adapted to support Va scraper 69 which extends across the entire length of the adhesive roller 47. Auxiliary Scrapers 70 and 71 disposed adjacent each end of the adhesiveroller 47 are supported by springs 72 and 73 from the portion 66 of the frame 65. These springs 72 and 73 may be adjusted along the length of the portion 66 by means of wing nuts 74 and 75. This scraper 69 is ordinarily disposed a little distance from lthe drum 47 and regulates the thickness of applications of the adhesive on the roller 47. On the other hand, the Scrapers 70 and 71 are generally disposed closely against the surface of the drum 47 so as to scrape all the adhesive from the drum-.47 along those portions of its area which do not contact with the paper 8. Beneath the drum 47 I provide and support in any suitable manner an adhesive trough 76 into which the drum 47 dips constantly. It will be noted that as long as the motor 34 is rotating, the drum 47 is moving regardless of whether the Winding drum 7 is in operation Ior not. This operation is provided so that the adhesive has no time to dry on the drum 47, it being constantly in rotation and dipping into the fresh adhesive. 1t will be observed, therefore, that as one end of the roller 47 moves with respect to the face of the drum 7 its bearing block is permittedto turn on the lation with the pressure roller, so that the yScrapers may always be accurately spaced from the surface of the roller and yet permit the flexible movement of either end of the pressure roller. This-accurate relative alignlnent is achieved by reason of. the fact that only one end of the scraper frame is rigidly fixed with relation' to the pressure roller. Asy shown in Fig. 3 particularly, the'paper 8 extends between tension pulleys 77, 78 and 79 suitably journaled in a frame 80 supported on a bracket frame 81 from the main frame ot themachine. v With respect to the winding drum 7 it will be noted, particularly from Figs. 3, 4, 5,

6 and 7, vthat this drum is split along its and 52 are held with their upper ends andm length to provide slightly spaced abutting roo llt',

'liu

edgeportions 82 and 83 which are cut at an Yacute angle. VV-ithin the drum, adjacent the slit and the edge 82, are disposeda plate \or a plurality of plates 84 which extend across the slit and are suitably bolted adjacent the edge 82. These function in a manner hereinafter to he described. This drum, merely by'reason of its iexibility and by reason of-being split, may be collapsed by any suitable mechanism adapted to draw the edge 82 downwardly, as viewed in Fig. 4, away from the edge 83. In this manner the average diameter of the drum is reduced s uliciently to permit the wound drum or cylinder thereon to be removed very readily. The plates 84, of which there may be a plurality provided along the length of the drum between the edge 82, are provided to prevent the edge 82 from moving outward beyond the edge 83. In other words, when these plates are ,contacting with the inner plates of the drum beneath the edge 83, the drum has assumed substantially its proper curvature, as illustrated in the drawings, a true circle. On the ends of the winding drum 7, I provide cam plates 85 and 86 suitably connected thereto, which are adapted to be engaged by` cam levers 87 and 88 connected to the shaft 89 which extends through the winding drum 7. This shaft, at one end, is provided with an operating handle .90 whereby the cam levers 88 may be engaged -with or disengaged from the cam plates 85 and 86.. As vlewed in Fig. 4, the handle 90 -is in a position to cause the engagement of the lever 88 with the plate 85 and the corresponding engagement of the cam lever 87 with the plate 86. .In this engaged position the plates 84 are in their normal position bearing against the under face of the drum adjacent t e edge 83, and the drum in this condition is in a true circular form.-

As shown in the drawings, andas comprising one preferred form of the invention, the flexibility of the drum is provided not only by splitting it, as above'mentioned, but by making it of two sections 91 and 92 which may be connected together by hinges, such as 93, a plurality of which may be provided throughout the length of the adjacent hinged edges of these two sections. However, it is to be understood that the drum may be made of material flexible enough to giveA at the edges 82 and 83, without being made'of two independent hinged sections'as shown. When the handle 90 is properly moved, the levers87 and 88 release the plates 85 and 86, whereby the edges 82 and 83 draw apart to collapse the drum and reduce the average ydiameter suiciently to permit the removal of the cylinder readily therefrom. By this meansI have provided a cylinder .which is readily collapsible and yet when in its normal operatiyeppositionlis absolutely true and strong. As shown in Fig. 7, the end ofl the paper 8 can anywhere be fed in between the edges 82 and 83 and gripped between the under-face of the drum and the plates 84.- When the handle 90 i.r` moved to its operative position, the end of the paper is thus firmly locked; and when the drum is completed, the turned-over end of the paper will readily slip out with the drum.

In Ithe event that I desire to wind drums of dierent diameters, it becomesnecessary to provide a simple and readily applicable attachment whereby these drums may be wound. I may provide different, separate drums. which can be mounted on and removed from the shaft 9 as above mentioned, but I prefer to use the attachment shown in Fig. 7. This attachment comprises an auxiliary drum 94 of the desired diameter which is also split similar to the drum 7. auxiliary drum 94 is slipped on over the drum 7 and-'is provided with a plurality of bolts or set screws 95 which extend from the drum 94 to the drum 7 and engage in any suitable predetermined apertures therein. These set screws extend through bores in spacing` sleeves or spacer bars 96, of which there is one for every set screw. These spacing sleeves .96 are of the exact length to position the auxiliary drum 94 the proper diametrical distance from the drum 7. It becomes, therefore` merely necessary to align the apertures in the sleeve with the apertures in the drum and to tighten up the set screws 95 in order to attach the auxiliary drum to the normal drum 7.

I have, therefore, provided an attachment which may be made in many sizes, whereby this machine can be adapted to wind and form cylinders of diameters varying over a wide range. I have also provided means whereby the paper or other laminated material is firmly and accurately gripped by the winding drum. I have provided means whereby the winding drum, either with orwithout the attachment, can be very quickly and easily collapsed to permit of the withdrawal of the cylinders therefrom. I have also provided an adhesive 4and pressure roller the end portions of the axis of which and connected to resilient pressure producing means in such manner that each end of this roller may be forced against the winding drum with any desired and redetermined pressure independent of t e other end. By reason of this accurate and .independently' regulated pressure-applymg means, the adhesive and pressure roller will not only yield as a whole but will oscillate yieldingly due to variations in the quality or thickness of the paper and variations 1n the consistency of the adhesive, so that"al though one end may momentarily move *are independently and pivotally mounted away from the winding roll, nevertheless, 1 substantially the whole roller is still 1n effective action. It is found that this oscillating flexible contact is the only one which will accurately and .truly produce a lami I .as

nated wound cylinder without the necessity of trimming up the redges thereof after winding and in which the adhesive is-ap plied and the laminations are connected firmly and uniformly throughout their entire length. n

By reason of the fact thatthe sprocket 41 is mounted on the pivotal point for the bars 51 and 52, and in View of the fact-that the sprocket. 43 is mounted on the same shaft 44 with the adhesive roller 47, the power transmission between the motor 34 and the adhesive roller is uninterrupted regardless of the movements of the adhesive roller. Furthermore, the belt connection between the power system and the adhesive roller permits the adhesive roller to be moved at any desired speed when it is turned away from the winding drum 7 but causes it to move with the same linear speed as the winding drum 7 when in contact therewith by reason ot' the slippage of the belt 38. In this manner the pressure is properly applied and the adhesive is consistent throughont. In other words, the pressure at each end of the adhesive roller may be regulated and varied regardless of the pressure applied at the other end of the adhesive roller. This regulation is determined by the circum'tances and conditions of operation of the machine and also by reason of the characteristics of the particular material being wound and adhesive being applied. It will also be noted that Whenever the clutch members are engaged that the adhesive roller may be simultaneously brought into contact or engagement with the winding drum 7.

For the purpose of the easy cutting of the paper w ich is being wound i-nto a drum, the clutch, by being operated by separate pedal, can be released without withdrawing the pressure roll upon the winding drum. This thereby stops the winding drum with-` out releasing the pressure roller, although the complete. operation ofl both pedals will either release or engage both the clutch and the pressure roller. This separate operation is useful when the paper is being run. from the roll and it is desired to cut it olf close to the machine. vIn this case it is important that the adhesive and' the pressure rolls remain in their pressure relation, in contact, so that the winding drum can again be started and finish the laminated drumwithout any interruption of the adhesive on the surface ofthe paper. This isparticularly true since it is necessary to roll the winding"v drum an vadditional revolntion'sothat the adhesive can bel applied tothe outsidefcoat.

The' provision of the above-mentioned mechanical features and 'their combination with each other to perform-the functions described,.lhas resulted in a machine compara-4 tively simple in construction and operatim, 'inexpensive temanufacture and operate,

'and on which manyfks-iz'c-s-of drums can he quickly and etiicientlyfmadewith a mininum of adjustment ofA- the parts during operation and Aattention on- Athe -part of `the operator. f c ,l

In Fig. 8 I.. have shown a vpipe 97, swiveled at 98 and suitablywsupported in any manner, from which depending p ipcs 99 extend to a perforated pipe 100. This erforated pipe 100 "extends along paralle to the surface of the windingf'drum and is provided with a plurality-fof apertures through which adhesive may flow yon to the paper. An adjustable rod or plug 101 is disposed in each end of thepipe'lOO to control the width of apertures permitted to remain open in accordance with the width of the paperl being cut and wound. By this simple device I can provide a separate adheslve ap-` plying means independent of the roller 47,

the major purpose of which roller is to regulate the pressure being applied to the paper and the thickness of t c adhesive thereon. This se arate adhesiveapplying means may also e used fory app heavy coating of waterproof adhesive on the outside `of the completed drum or cylinder.
