In `the manufacture of'paper for cartons and lexiblegcontainers' or goods OtVarious kindsfdiliieulty has been experienced in obf tainingl paper stofcl which will not "tear made up into manufactured articles. This clilliculty is clue to the fact that the fiber orf.

the rnat'eriallusetl lor making comme/rea' paper stock of 'thiskind is always in the .le direction of travel of the sheet through the j machine and hence oersvery little reslstance to tearing strain in the direction of A the grain.v 1

The object, therefore,`of` my Ainvention is to provide' an attachment for a paper .in achine by means of which a part ol the fibers are caused to assume -a position c'rossvvise of the sheet -While it is in a p'ulp 'or semi. liqui'el "form, so that When compressed to ormthe inished paper stockya part of the fibers will lie crosswise to the ordinary grain of thestock and equalize'the strength of the stoel; in any direction.

'lhe invention consists generallyrv in. va rions constructions and combinations, all as 'hereinafter clescriberl. andl particularly pointed out in the claims."

ln the accoinpanyiijip,n drawings forming part ol this specilicatioinj Y llligure l' is a detail sectional View, showing the application ol my inventionto yone of the clrums of a paper making machine,

Figure 2 'is a `sectional view on the line 2-2 et' Figure. 1.,

vFigure 3 is a detail sectionalview of the to the stream ot tlruins therein.'

ln the (lrairing7 Q represents a trough hath ingl pocli'ets 2 anel l tliorinetl hv battles 5 anal C. To these pockets theserni-liuuicl pulp is teilte-reel. the usual manner. Drums-l are rnountetl in the trough enel spaced troni a curvetl Wall e therein in which space the pulpis clelivererl to engaged and inthe-.reel

,up by theisuraceof 'theirevolving drum. A belt .9, usually of, ilannel, ismounted to -mov above the drums, pressure. being en ertecl on the upper side of the belt' by means of'suitable rollers 1t) supported on pivotecl arms 11: All this is ordinary construction 1n machines of this type.

.I have found in making-ordinary paper or carton stoclrsthat .the tendencvI of the fiber, due to the movement of the web or sheet in a semi-liquicl form through the inachine, is to assume a position lengthwise of the web or sheet and heneejwillonlyresist A'gi-twisting or tearing strain when it is applied crossi'vlse tothese vfibers.` Obviously,

in the' manufacture of cartons or containers` it is necessary' in the economical use oli the carton stock that it be cut so thata considerable portion o the strain will be. lengthwise of' theI fibers, and I have fountl that when this is clone, the container .or-carton Willofer butlittlef resistance to the strain of rough'handling or usage, but Will easily collapse, toy the destructionor damage ot' thecontents of theV carton.

To avoiel this difliculty, il proviele a heaol 12 having an air chamberA 13' therein conimunieating through a pipe lll: with a source ot'air supply. The pipe has a bearing at 15 with screws 16 ancl 17 by means of which the pipe may be loclretl anal the head arl. justecl 'at any clesirecl angle with respect'to the surface of the drinn,- anel the stream of pulp :moving thereover. will, of course, be very' slight anal will here. no material effect on the pesitionoi" the air delivering pipe. It suitahiegauge 18 is connectedwith the pipe by means of "Whichtthe air pressure may be deterniinecl. The Wall of the head. 12 is preferably curvefl, as shot-Jn,

This adjustment in Figure 37 to contorni substantially to the curvature oi the tlru'nfi 'and the',4 stream oli pulp and is proviflecl with a series einer ales 19 having' con'iparativeljf `narrow diie charge slots 20 through which the air is elischargeclupon the surface ot the pulp. nozzles, as shown in Figure Il, are preferably.

inclined so that their discharge orifices are at 'an angle to the plane the heael, thereby directing the air currents obliquelgT upon the surface olf the puip.

The effect olf the currentsis to eu usek the fibers liowinn in 'the web or pulp lenu wise thereotanel the upper surta be cleecterl and turnetl crossrrise oil the t u vll) or diagonally thereof, as indicated in Figure G, while the fiber in the underside of the web, not being affected by the jets of air, will continue in their lengthwise position, and when the Web.or sheet has fiowed past the head, one surface will have fibers lying one Way of the' sheet and the other surface will have fibers lying the 'opposite Way or diagonally, so that the Web will have a veneered effect, with the grain running in different directions. The pressure of the air jets will be sufiicient to affect the fibers on one side to a point nger/thetransverse center of the web and the degree of the pressure may, of course, be varied to adapt the device to Webs or sheets of dierent depth.

The size of the head may. of course, be varied to increase or decrease the area of the Web affected by the fluid pressure.

I claim as -my invention:

1. The combination with a trough adapted to contain a supply ofsemi-liquid pulp, of a drum-mounted t'o revolve in said trough and having a surface for gathering up the pulp in a thin sheet, a belt above said drum,-

in position to receive the pulp therefrom, a head mounted transversely of said drum between said trough and beltand having a series of nozzles for delivering fluid pres` sure upon the surface of pulp and turning the fibers thereof transversely or at an angle to the direction of movement of the pulp.

2. The combination, with a revolving drum and means vfor delivering paper pulp in semi-liquid form thereto, of a head having an air chamber therein communicating with a source of air under pressure mounted adjacent to said drum, said head having a plurality of nozzles, provided vWith discharge orifices at an angle to the'surfaceof.; the sheet of pulp and' adjacent thereto for directingstreams "of air. into the pulp for the purposespecified.

3.. The combination a, trough adapted to Vcontainarsilpplyof pulp in semi-liquid .Y

form, of a drum mounted to revolvefi'n said trough and having a surface for gathering up the pulp,.a belt mounted to receive the semi-liquid pulp from said drum, a pipe extending transversely of said drum between said belt and trough, a head mounted thereon over-hanging" said drum and having a comparatively broad under surface, a series of nozzles provided in the under surface of said head, and said head having a chamber head and projecting toward said drum at an angle tto `the sheet of 'pulp'"thereon," and adapted to direct streams of uid 'pressure into the surface of the pulp, and a blanket lil) Whereto the pulp is delivered by said drum.

5. The combination with a series of troughs adapted to contain semi-liquid pulp,

of drums operating in said troughs and hav- `surface of the pulp on said drum at an angle to the direction of movement of the pulp for `turning the-fibers thereof transversely or at an angle to such movement.

In witness whereof, I have hereunto set ing surfaces for gathering up the,pulp, a

my hand this 4th day of September, 1920. K
