MACHINE FOR FACING CORRUGATED PAPER.

Application filed January 12, 1911.

- specification, reference being had to the ac companying drawings.

My invention may be advantageously employed in machines of the class described in Letters Patent of the United States #917,503 granted to me April 6th, 1909, which being supplied with a web of corrugated paper having plane paper webs upon opposite sides thereof and adhesive material at the contiguous surfaces of said webs, progresses said plane webs in contact with said corrugated web and contemporaneously dries the same; thus producing a multiple web which is a plane faced cellular paper board. The machine described in said Letters Patent includes endless belts of flexible sheet metal having opposed runs between which the paper webs are fed; means for driving said belts in unison; means for varying the space between said runs to fit webs of different thickness; and means for drying said webs, comprising opposed normally stationary heaters embracing said belt runs and relatively adjustable in correspondence with variations in the space between said runs. Said stationary heaters are plane faced steam boxes over which said belt runs are drawn, in frictional contact therewith, to maintain the belt runs in engagement with the paper webs so as to maintain and progress the latter in proper relation during the drying operation.

It is the object of my invention to provide such heaters with means to support such belt runs, or the paper webs without frictional contact with the plane surfaces of the heaters, and, as hereinafter described, my invention includes opposed steam boxes which are relatively adjustable to vary the space between them in accordance with the thickness of the fabric which is to be produced, having recesses in their respectively opposed and otherwise plane surfaces in which are mounted cylindrical rollers which may be co-extensive with the width of the steam boxes transversely with respect to said webs, or may consist of cylindrical sections transversely spaced upon a common shaft, but in either event each roller projects slightly beyond theplane face of the box in Specification of Letters Patent.

which it is mounted sons to support the contiguous belt run or web without frictional contact with the box.

. My invention comprises the various novel features of construction and arrangement hereinafter more definitely specified.

In the drawing: Figure I is an end view of a series of heaters embodying my invent1on, having means to simultaneously move the axes of the upper rollers, to vary the space between the upper and lower rollers. Fig. II is a sectional view showing the interior construction of a pair of heaters having a pair of flexible metal belts and the cellular fabric embraced between them. Fig. III is an inner face view of one of the adjustable roller bearings shown in Fig. I.

In said figures; the opposed'heaters 1 and 2 are separable metal boxes, the former being maintained in stationary position on the frame of the machine and said boxes beins. vertically adjustable to vary the space between them and the boxes 1 by means of the set screws 3 which extend through the lugs 4'and bear upon the upper surfaces of the lugs 5. Steam or other calefactive fluid may be conveniently supplied to and condensate drained from said

heaters

1 and 2 by means of the stationary pipes 8 and 9. Said pipes, 8 have stationary branch connections 11 "tn the boxes 1 and have stufling boxes 12 through which lhe branch connections 13 leading to the boxes 2 may be reciprocated without disconnection, so to not only permit of such variation in the space between the upper and lower heaters as is necessitated by the differing thicknesses of the cellular board products of the machine but also to permit the upper heaters 2 to be raised to an abnormal extent so as to afford access to the space between the heaters and thus permit removal of any obstruction from said space. As shown in Fig. II said

boxes

1 and 2 have respective recesses 15 and 16 in their opposed plane faces in which are mounted

respective rollers

17 and 18 which are journaled in the

detachable bearings

19 and 20 at the opposite ends of said boxes so that said rollers project slightly beyond the plane faces of the respective boxes in which they are mounted and respectively engage the

proximal runs

22 and 23 of the flexible metallic belts aforesaid, so as to prevent contact thereof with the opposed plane faces of said boxes while maintaining said belt runs in predetermined close relation to fit the cellular fabric comprising the corrugated web 26 and opposite plane webs 27. It may be observed thatv in the form of myinvention'shown in Figs. I and II, the space between the upper and lower rollers and the space between the upper and lower heaters may be contemporaneously increased or diminished by the rotary adjustment of said screws 3; the telescopic arrangement of the branch pipes 13 permitting such adjustment without breaking the connections to the steam supply and drain. However, I find it advantageous under some circumstances to provide means to increase justed by the bushings aforesaid, I find it convenient to provide means to simultaneously operate all of said levers 31 and as shown in Fig. I such means includes a rod 32 connected in common to said levers 31 by the adjustable couplings 33. It may be ob- ;served that the space between the

rollers

17 and 18 may be increased by moving said rod '32 in one direction to simultaneously raise {all of said rollers 18, or, said space may be jadecreased by moving said rod 32 in the op posite direction to simultaneously lower all of said rollers 18.

I do not desire to limit myself to the precise details of construction and arrangement above described, as it is obvious that yarious inodifications may be made therein without 'liieparting from the essential features of my invention as defined in the appended claims.
