MACHINE FOR FACING CORRUGATED PAPER.

Specification of Letters Patent.

Patented Nov. 23., I915.

Application filed October 28, 1911. Serial No. 657,376.

To all whom it may concern:

Be it'known that I, JOHN N. HAHN, a citizen of the United States, and a resident of the city of Cleveland, county of Guyahoga, and State of Ohio, have invented certain new and useful Improvements in Ma-- chines f'or Facing Corrugated Paper, of which the following is a specification.

This invention relates to machines for applying one or more facing strips to a strip or strips of corrugated paper in the manufacture of so-called faced corrugated paper or cellular board. In the manufacture of this cellular board, a strip or web of paper is usually first run between a pair of interfitting corrugated rolls to corrugate said strip or web, paste being applied to the crowns of the corrugations on one side of the corrugated web and a facing strip applied thereto. When the paste has set and dried, this single-faced corrugated paper is generally run through another machine which applies a second facing strip to the -crowns of the corrugations on the other side thereof, thus making a comparatively strong, stiff and resilient yet very light paper board which is used for cartons or packages, or for partitions in cartons and packages, and for many other purposes.

It is well known that in order to produce first-class corrugated paper board, the facing strip or strips must be held in close contact with the pasted crowns of the corrugations until the paste has become thoroughly set and dried. Where the strips are run continuously through the machine, the drying operation is facilitated by the application of heat, otherwise the machine would necessarily have to be of unduly great length.

yond their normal elastic limit-otherwise the strength and resiliency of the finished product would be impaired if not wholly destroyed.

One objection to the use of friction rollers to advance the strips has been that these rollers parallel the corrugations in the corrugated strip, whereby there is-theoretically, at least-only a single corrugation receivingthe pressure of the rollers, this pressure belng received along the line of least strength, yet in spite of this objectionfeed ployed on account of other advantages which -doubtless outweigh the disadvantage referred to.

The principal object of the present invention is the provision of a machine in which feed rollers may be employed to advance the strips, said rollers being so mounted and adjusted that instead of the pressurebeingexerted along the line of a single corrugatlon, that from each roller or from each to materially reduce friction and render posslble the employment of a comparatively much shorter machine with a consequent.

economy of power. I have further in View a machine which is otherwise simple in construction and dependable in operation.

My invention will be more readily understood by reference to the accompanying drawings, forming a part of tion, in which Figure 1 is a sectional side elevation of a complete machineembodying my invention, partly broken away; Fig. '2 is a top plan View, with the top or cover of the casing removed, of one end of the double-facing machine proper, partly broken away to show the lower feed rollers; Fig.3 is a cross-section taken substantially on the line 3--3 of Fig. 2; Fig. 4: is an enlarged fragmentary section, taken substantially on the line 4-41; of Fig. 2, andFig. 5 is a side elevation of a modification of the mechanism for feeding the paper strips into the machine, show1ng the 105 manner 1n which second facing. strips may this specifica- 65 rollers of this character continue to be embe simultaneously applied to a plurality of single-faced corrugated paper strips.

Referring now to the drawings in detail, numeral refers to a. roll of single-faced corrugated paper, as the same has been received from the corrugating and single facing machine, this roll being preferably "mounted upon a spindle (3 carried by the movable frame 7 which is provided with rollers or casters 8 in order that the same may be readily transferred from place to place and adjusted in position to direct the I strip from said roll to the pasting mechfrom. A second roll 13 of plain paper is rotatably mounted in the standards 14 and is adapted to supply the strip 13 therefrom around the roller 13 and against the pasted crowns of the corrugations of the single-faced corrugated strip 15. From this point, the juxtaposed strips are directed substantially horizontally into the box or casing 16. This box or casing 16, which contains the double-facing mechanism, is suitably supported at any preferred height by the legs 17 and is preferably provided with a hinged or otherwise removable cover 18 to afford access to the interior thereof. I have shown a coil 19'of steam pipes in the lower part of said case, in order to facilitate the drying operation through the application of heat, although it will be apparent that the superposed strips may be heated in many other well-known ways.

' The most important feature of the present invention is the employment of gripping or friction rollers between which the superposed strips are directed and which are positively rotated to advance said strips, said rollers being obliquely instead of rectangularly disposed with reference to the direction of movement of said strips. Inasmuch as the corrugations run transversely of the moving strips, it will be apparent that if the gripping or friction rollers are obliquely disposed with reference to the direction of movement of said strips, they will also be obliquely disposed with reference to the corrugations, whereby each roller, or each pair of rollers if arranged in pairs, will exert pressure against a plurality of the crowns of said corrugations, instead of along the line of a single corrugation. It will furthermore be apparent that if an obmenace liquely-disposed advancing roller extended across the entire contiguous face of the strip, rotation thereof would have av tend ency to drag the moving strip to one side or the other, according to the disposition of the roller, and I therefore provide two rollers instead of the usual single roller, each of these rollers extending substantially half of the distance across the advancing strips, and each being oppositely inclined with reference to the direction of movement of said strips, whereby the laterally-directed advancing forces are counteracting and the strips will be advanced in the desired forward direction only, the same as if a single rectangularly-disposed roller were employed. In view of the fact that upper and lower bearings for these rollers must be provided, one series of bearings extending along the middle line of the strips, it will be apparent that the middle bearings for the upper rollers must be suspended, in order that the moving strips may pass underneath the same. In mounting the upper rollers, therefore, I provide a series of transversely disposed I-beams 2O 20, which are supported from the floor of the casing 16 by means of legs or standards 21, one at each end of each beam, each of these legs or standards being screw-threaded into a base 22 and a cap 23, whereby the height of said beams 20 20 from the floor of the casing may be varied to adjust the space between the upper and lower friction rollers to accommodate the same to slightly varying widths of corrugated strips. Secured to the bottom flanges of the I-beams 20 are the longitudinally arranged I-

beams

24, 25 and 26, the Lbeam 25 being located along the middle line of the casing and the I-beams 2 1 and 26 at the sides thereof. Secured to the bottom flanges of the middle I beams 25 are the blocks 27 on one side and the blocks 28 on the other side thereof, providing bearings for the axles at the inner ends of the rollers 29 29 and 30 30, respectively. The Lbeams 24: and 26 are similarly provided with

blocks

31 and 32, respectively, forming bearings for the axles at the outer ends of said rollers. These bearing-blocks are so located and disposed as to incline the rollers 29 29 and 30 30 in opposite directions from a line rectangular to the longitudinal axis of the machine, as clearly shown in Fig. 2. It will also be noted that these bearingblocks are so located that the rollers are in staggered arrangement, which is necessary memos M in location and arrangement to the I-beams .24, 25 and-26. Upon the top of the middle I-beam 34 are mounted two series of

blocks

36 and 37, corresponding in location and arrangement with the

blocks

27 and 28 on the beam 25, and similarly providing bearings for the inner axles of the lower rollers 38 38 and 39 39. The

beams

33 and 35 are similarly provided with

blocks

40 and 41, respectively, which provide bearings for the outer axles of these rollers. The arrangement of these bearings on the

lower beams

33, 34 and 35 corresponds in all respects to the arrangement of the bearing-blocks suspended from the

beams

24, 25 and 26, whereby the lower rolls 38 38 and 39 39 have the same inclination with respect to the axis of the machine as the upper rollers, also insuring the location of each one of the lower series of rollers immediately underneath and adapted to coiiperate with one of the upper series of rollers. This arrangement of rollers in cooperating pairs is not essential, although it is believed that it will produce the best results.

To the outside faces of the

upper beams

24 and 26 are secured the downwardly-projecting

brackets

42 and 43, respectively, in the ends of which are journaled the

shafts

44 and 45, one a each side of the machine. Similarly secured to the outside faces of the

lower beams

33 and 35 are the

upwardlyprojecting brackets

46 and 47, journaled in the ends of which are the

shafts

48 and 49. The main drawing" shaft 50 is provided with the usual fast and

loose pulleys

51 and 52, and is provided with bevel-

gears

53 and 54 in mesh, respectively, with a gear 55 on the shaft 48 and a gear 56 on the shaft 49. The

shafts

44 and 48 are intergeared together by means of gears 57 and. 58, and the

shafts

45 and 49 are similarly intergeared together through the gear '59, its counterpart of the shaft 49.

The outside end of each roller in the upper series thereof is provided with a bevel-gear 60 in mesh,'on one side of the machine with bevel-gears 62 on the shaft 45. Similarly, the outer end of each roller in the lower series is provided with a bevelgear 63 in mesh, on one'side of the machine, with a gear 64 on the shaft 48.and on the other side of the machine with a gear 65 on the shaft 49. It will be apparent that when the main driving shaft is rotated in the usual manner from any convenient source of power, both the upper and the lower series of rollers will be positively rotated at uniform velocities, the upper and lower series in opposite directions, whereby the paper strips therebetween will be advanced. I In order toproperly direct the strips into the machine, I prefer to provide an initial pair of

friction rollers

66 and 67, the axles of these rollers being journaled in bearings in blocks similarly secured to the

beams

24 and 33 at one side of the machine, and the disposed with respect to the direction of movement of said strips, whereby said strips are initially subjected to forces oflesser degree which act in a direction parallel to that of the moving strips. The upper 75 roller is driven by means of bevel gears 68 and 69 in mesh, respectively, with similar gears 70 and '71 on the

shafts

44 and 45, while the lower roller is similarly driven by means of gears 72 in mesh with similar 0 gears 73 on the

shafts

48 and 49, respectively. I also prefer to provide a similar pair of correspondinglydisposed and arranged rollers 74 and 75 at the other end of the machine, these rollers being "mounted 5 and driven in a manner precisely the same as the

rollers

66 and 67. While the frictional forces generated by the obliquely disposed rollers, which tend to drag the strip toward one side or the other of the machine, are substantially counteracting, and, therefore, tend to preserve the alinement of.the strips and their movement in a forward direction only, it is not so easy to secure such a nicety of adjustment of these oblique rollers as to equalize the forces generated by each pair thereof. I therefore provide the initial and final pairs of rectangularly disposed rollers in order to insure the preservation of the desired alinement and direction of movement.

It will be noted with respect to the effect of the employment of obliquely disposed rollers, that not only is the pressure from each roller distributed over the plurality of corrugations, thus permitting of the applicationof greater force or pressure without crushing the corrugated strip, whereby a fewer number of rollers may be employed, and a machine of this character materially shortened, but the strips in advancing must necessarily-have a relative lateral movement with respect to the face of each roller, the rollers thus having what is termed an ironing' effect, which is not only in itself much 15 to be desired, but in which renders unnecessary the employment of presser plates intermediate the rollers and between which the strips must be drawn subject to nov small degree of frictional resistance. While the employment of presser plates is unnecessary in a machine embodying the present invention, the fact that the oblique rollers in each of the lower and upper series must be spaced at some distance from each other, due to the overlapping of the ends thereof at the middle of the machine, I have found it desirable to mount upon the

Ibeams

33, 34 and 35 a series of plates 76 76, preferably in the form of T-bars, as best shown in Fig. 4, the upper 139 and horizontal faces of which provide supports for the advancing strips and prevent any sagging of the combined strips or the lower strip alone.

In view of the fact that through the employment of my machine I am enabled to exert such comparatively great gripping pressure against the strips, I have found that I may simultaneously apply the second facing strip to each of two strips of singlefaced corrugated paper. Under ordinary conditions, the presence of two corrugated strips between the gripping and advancing means, would so diminish the resistance of the. strips to the gripping forces that the latter would have to be increased to the point of destructiveness in order to overcome the frictional resistance of the strips to movement. With the disposition and arrangement of rollers as herein described, however, I find that the capacity of the machine may be doubled with little if any increase in the power required to drive the machine.

In Fig. 5 I have shown two rolls 7? and 7 8 of single-faced corrugated paper, mounted on movable frames 79 and 80, respectively, and so arranged with reference to each' other as to permit of the unrolling of the respective strips in superposed relation and Withthe corrugated strips on the outside. Obviously, two pasting devices will be required, both ofwhich I mount upon a suitable stand or support 81. The strip 82 from the roll 78, with the corrugations on the underside thereof, is directed under the idler roller 83, thence between the rollers 84: and 85, thence to the pasting roller 88 where paste is applied in the manner described to the crowns of the corrugations, and thence to the roller 8?, where it meets the facing strip 88 from the roll 89.

- The strip 90 from the roll I? of singlefa'ced corrugated paper is directed over the roller 78, thence around the idlers 91 and 92, thence to pasting roller 93, around the roller 94 and between the rollers 84: and 85, where it meets the strip 95 of facing paper from the roll 98 thereof. From these rollers 84 and 85, the strips are passed in superposed relation to the strips from the rolls 7 8 and 81 into the machine hereinbefore described.

I I Vfith respect to the simultaneous applicationof two facing strips totwo single-faced corrugatedstrips, it will be noted that the second facing strip, which has just been ap-' plied, is on the outside ineach case, and therefore in position where evaporat1on 1s facilitated and the drying operation hastened. This being the case, the corrugations of the single-faced strip from one of the rolls must be on top, and it has been found impracticable, if not impossible, to satisfactorily apply paste to the crowns of the cormenses rugations from above the strip. Therefore, in connection with the upper web, I have employed a number of idlers, as shown in Fig. 5, in order to reverse the direction of movement of this web for the pasting oper ation.

As the double-faced corrugated paper passes out from the end. of the machine, it is cut at regular intervals to form the same into sheets of suitable size. The mechanism for performing this cutting operation forms no part of the present invention, and I have therefore only shown fragments of a pair of coiiperating cutting knives 97 and 98 to suggest this adjunct to a machine of this character.

Many modifications of minor details of my improved machine for double-facing corrugated paper will doubtless readily suggest themselves to those skilled in the art to which it appertains, and I therefore do not desire to limit my invention to the specific construction herein shown and described.

In a machine of the character described, the combination, with means for directing a corrugated strip with and between plain facing strips into the machine, and means for applying an adhesive to crowns of the corrugations, of upper and lower feed and presser rollers obliquely disposed to the direction of movement of said strips through the machine, means for equalizing the compressive forces of each roller throughout the length thereof, said rollers being arranged to collectively contact with the entire area of each face of the traveling compound strip, and a series of supporting plates intermediate the lower rollers.

33. In a machine of the character described, the combination, with means for directing a corrugated strip with and between plain facing strips into the machine, and means for applying an adhesive to. the crowns of the corrugations, of feed and )resser rollers obliquely disposed to the direction of movement of said strips through the machine, means for equalizing the compressive forces of each roller throughout the length thereof, said rollers being arranged to collectively contact with the entire area of the contiguous face of the traveling compound strip, all of said rollers being included within a suitable casing, and means for heating the interior of said casing.

In testimony of the foregoing, I have hereunto set my hand in the presence of two witnesses.
