18 Claims.

This invention relates to a paper making machine of the Fourdrinier type.

. It is an object of the invention to provide a Fourdrinier machine which is of simple and light weight construction throughout, and which is so constructed that it operates in a most efflcient manner to produce a high. quality of paper.

Itis also an object to provide a novel construction' of the wet end of the forming machine which enables the production of an improved sheet of paper and provides for a better interfelting of the fibers and control of the characteristics of the sheet while the initial formation is taking place.

It is a further object to provide in a machine of this character means for assuring that the stock is deposited on the forming wire in the desired uniform manner and that a proper in; terfelting of the fibers is produced where efiec tive to give a sheet of superior characteristics.

Other objects and advantages wil be apparent from the following description, the accompanying drawings and the appended claims.

According to the present invention, a very simple and light weight construction is provided in which all boxtype girders or the like on the forming table are eliminated. The oper-- ation of changing the wire is facilitated by providing a forming table which is divided into sections each having a light weight construction,

the stock and a resultant fuzzy .sheet.

certain of the sections being laterally removable and eaclr section being relatively small and light in weight as compared with the entire table. Another section is adapted to be given a lateral shaking motion and because of its light weight'construction, it can be vibrated at high speed and/oramplitudes'with a minimum of driving energy and of depreciation on the machine. This latter section is constructed-so that it can be readily disassembled and the necessary parts removed along with the removable section when it is desired to change the wire. A

Furthermoremeans are provided for assuring that the stock is deposited on the forming wire .in the desired uniform manner and that a proper interfelting of the fibers is produced where efiective to give a sheet of superior characteristics. In the past it has been customary to provide means at the breast roll end of the machine where the stock is introduced into the forming wire to prevent the too rapid escape of water downwardly through the forming wire,

this means usually being the form of an apron, or imperforate shield, extending from the head box forwardly over the top of the forming wire for a suitable distance: According to the present invention no apron is used, but the rate of discharge of the stock through a suitable slice is controlled by forming a throttling pathway of relatively limited extent below the initial-portion of the forming wire so as to prevent such rapid discharge through this initial area as to cause an upending of the fibres of The pathway is provided between a breast roll of lateral shaking motion, and a forming board adjacent thereto; these two parts have their point of closest approach beneath the wire and the spacing at this point is less than the exposed area of the initial section of the forming wire between the breast roll and the forming board. This pathway is of-such controlled dimensions with respect to the exposed portion of the formrelatively large diameter, which may be given a" second slice is w forming board on which the wire, as it travels under the slice, is supported, provides a stationary smooth surface which in conjunction with the slices, provides an accurate aperture for accurately gaging the depth of the stock and preventing inequalities in the distribution thereof.

Provision is also made for assuring that the stock, as it flows from the head box, will be in the desired state of agitation and that the proper interfelting of the fibers will be produced as the formation proceeds.

Referring to the drawings which illustrate a preferred embodiment of the invention, there is shown a breast roll at 10. The roll is mounted for shaking movement upon a pair of vertically arranged spring supports 11 and similar horizontal spring supports 12, said supports being positioned at opposite endsof the breast roll to support the same from a base 13. A head box is indicated at 14 from which the stock flows onto the traveling Fourdrinier wire 15. A deckle device consisting of a deckle strap 16, or any other suitable type of deokle device may be used if desired.

Located forwardly of the breast roll is the forming table which, in the embodiment shown, comprises a first section 20, a second section 21, and a third section 22, these sections being substantially of the proportions shown, although these proportions may be changed or varied to meet any desired conditions.

Section 20 of the forming table is mounted for removability but does not have any shaking motion. ,In addition to its lateral removability, it is also mounted for vertical adjustment at each end. This section is supported from base pedestals 24 located adjacent the ends thereof.

. Each pedestal carries a vertically adjustable bracket 25 which forms a support for a laterally extending tubular track 26. An adjusting nut 27 threadedly mounted in a projection 28 of the pedestal serves to adjustably position the bracket and the track carried thereby.

A roller 30 mounted upon each side of the section is adapted to ride upon the track and to carry the side rail 31. The side rails carry the bearings 32 in which the individual table rolls 33 are journaled. The bearings are shown as removed in Fig. 1 to more clearly show the construction of this section.

The side rails are likewise provided with downwardly extending lips 35 which overlie the upper end of each of the pedestals 24' to serve as an abutment to limit the motion of the section toward its inner operative position. The lip is formed with an elongated slot 38 through which extends a pin mounted in the pedestal. A nut 37 is threaded onto the end of the pin to hold the section in operative position. The construction is such that the pin permits vertical adjustment of each end of the section to the limit of the slot and after being adjusted the nut is tightened and the entiresection is then held in the desired operating position.

When it is desired to remove the section, it will be understood that extension tracks 40, shown in dotted lines in Fig. 3, are mounted upon the extended end of brackets 25, the other end .of the extension track being supported from the machine floor by a removable bracket in a known manner. This provides a removable track which is only assembled in place for the period of the removal and consequently the floor space adjacent the machine is not perma'nently taken up with this track mechanism. If desired, in place of using table rolls for supporting the initial section of the wire, immediately after it leaves the breast roll, a forming board may be used. As illustrated in Fig. 1', an extending arm 45 is formed on the end of each table rail 31, extending toward the breast roll, upon which the forming board 46 is supported. This construction provides therefore, for supporting the forming board entirely from the first section of the forming table and consequently the forming board, having no operative conriection with any other portion of the machine, is readily removed along with this section of the forming table and'changing of the wire is thereby further facilitated. It will also be noted that at no point does any of the removable portion of the machine extend above or below the wire, and consequently it is not necessary to dismantle any portion of this section when it is removed, as it freely slides out laterally of the wire.

As shown in Fig. 7, the forming board 46 is also of light weight contruction and comprises a hopper section 47 and a plurality of laterally extending spaced. bars 48 supported thereon, each of the bars carrying a replaceable top plate 49. The. material used for the construction of the hopper and the bars is preferably a light weight metal such as aluminum, and the plates are preferably formed of a phenolic condensation product such as bakelite, which will provide a desirably smooth bearing surface for the wire, which is of relatively light weight, and which will not be subject to rust or deterioration. In such case, the plates are screwed into position on the cross bars by means of screws 50 which are also of bakelite, thereby assuring uniform and even wear upon the forming board so as to .prevent any possibility of ridges or the like being formed which would produce uneven wear on the wire and unevenness in the characteristics-of the formed paper. The spacing of the bars is such as to give the proper rate of drainage of water through the wire at this point.

The section 21 of the forming table is located at the point where the stock has reached the desired consistency for an effective shaking action to take place. This point will vary with various conditions of stock, wire speed, etc., but

generally will be substantially as indicated, in the middle third of the forming table. This section comprises a. number of table rolls, the number of which should be such as to provide for giving the desired lateral shaking motion to the wire.

This section is mounted for lateral shaking movement but it is not removable from the machine in the manner of section 20. It comprises a pair of table rails 60 which carry the bearings 61 in which the table rails 62 of this section are journaled. The table rails 60 at each side of the machine and at each end of the section are supported by a pair of spring supports 63 which in turn are carried by bracket members 64. The brackets are mounted for vertical sliding adjustment upon the adjacent pedestals 24 and adjusting screws 65 provide for giving the desired vertical adjustment to the section. Pairs nated from this section and it is therefore capable of vibrating at the desired rate and ampliand complicated construction has been elimitude to produce proper fiber interfelting without requiring the vibrating of an entire and massive forming table.

The third section 22 of the forming table is located immediately in advance of the shaking section 21, andis similar to section 20 in that it is not mounted for shaking movement but is adaptedto be laterally removed from within the wire. Briefly, this section comprises side rails '70 which support bearings '12 in which the table rolls are journaled. The side rails are mounted upon rollers 73 which are adapted to run upon tracks '74, the tracks in turn being supported and vertically adjustable by means of brackets '75 supported from pedestals 24 respectively. The side rail adjacent the one side of the machine is similarly provided with downwardly extending lip portions having guide slots and retaining nuts as described above with respect to section 20.

This section is also formed with a pair of cross braces 76 in the form of transversely extending tubes fastened to the side rails by means of flanges 77. This provides a very strong but light weight means for tying together the two parallel side rails of the section. It will be understood that this section may be adjusted vertically and removed on extension tracks '18 in the same manner as section20.

By means of the vertical adjustment at each end of each section of the forming table, the

. wire may be given an inclined travel, either upwards or downwards according to the particular operating characteristics desired. Or the central section may be either raised or lowered with respect to the other sections.

In advance of the last section of table rolls, is the usual suction box construction 80 comprising a plurality of suction boxes adapted to be removed laterally when it is desired to change the wire. The couch roll is shown at 81 around which the wire turns, and passing over the usual guide and tensioning rolls, it returns underneath the machine to the breast roll. The breast and couch rolls are removably mounted so that they can be removed axially when the wire is changed.

In Fig. 2 is shown the means whereby shake is imparted to the wire. A shaft 90, suitably J'ournaled, is driven from any suitable source of power, as by means of a rope drive 91 from a motor. The shaft extends along the side of the machine and opposite the breast roll an eccentric 92 is mounted on the shaft and connected with the bearing support 93 of the breast roll by means of a bar 94 and a spring link 95. It is to be understood that in accordance with the usual practice the eccentric collar produces an axial vibration in the breast roll which is so mounted on its spring supports 11 and 12 that an oscillating movement in substantially a single plane is provided. The spring link 95 further permits this free axial movement without interference from the driving-connections.

The same shaft 90 is likewise provided with eccentric collars 96 and 97 opposite shaking section 21 of the forming table and similar shaking connections are made from the collars to the shaking section. These connections comprise bars 98 and spring links 99. This likewise provides for a substantially 'uniplanar shaking movement in section 21.

If desired an intermediate shaking connection may be made to the wire guide roll 100, located on the lower travel of the Fburdrinier wire and adapted to support this wire in its travel from the tensioning mechanism to the breast roll. Roll 100 is supported on spring supports 101 and similar eccentric connections comprising collar 102, bar 103 and spring link 104 serve to produce similar vibrating action in this roll. The degree of travel of this roll is usually intermediate thatof the breast roll and the zero travel of the wire guide roll so that unnecessary wear on the wire is avoided.

Suitable means are provided in each of the eccentric devices for providing for a variable degree of throw or eccentricity. This means may take any desired form such as one eccentric cated within another, both being adjustable, and hence has not been illustrated in detail. It will be understood therefore that although the breast roll, the shaking portion of the table rolls, and the wire guide roll all shake with the same frequency and preferably in the same phase relationship, it is possible to vary the amplitude of shake at each of the points, or if desired, to shake either the breast roll alone or the table roll section alone. It is usually preferred, however, to shake the breast roll with a stroke of approximately and to shake the table roll section with a greater amplitude, of the order of to A". The frequency of the shake is usually between 150 and 400 shakes per minute. 1

A save-all construction is provided which is very simple and extremely light so that the overall weight of the entire machine is further reduced. The save-all construction further is of such character that it does not interfere with the previously described simple method of changing the wire. A trough 110 is provided which is supported in position underneath section 20 of the forming table. As indicated, the trough lies below the top run of the wire and above the return run so that it will be freely removable laterally with its section of the forming table. The trough comprises a pair of oppositely facing U-shaped brackets 111 which are attached by means of bolts 112 to the'bottoms of side rails 31. A plate 113 extending between the two brackets forms the bottom of the trough and plates 114 form the ends thereof. It will be understood that these 'last named plates are attached in any suitable manner, as for instance by welding, to brackets 111. The brackets 111 therefore serve the dual purpose of forming the trough and likewise are effective in securely tying the opposite side rails 31 of this section together, eliminating the necessity for additional reinforcing members that would increase the weight of the section. The trough is very simple and of light weight so that no great additional weight is added to this section such as would increase the difliculties of its removal.

A save-all comprising a pan 120 has its forward end supported upon the side of trough 110 and extends toward the breast roll so as to underlie the forming board 46. The end of the save-all adjacent the breast roll may be supported from arm 45 by means of bracket 121. A doctor 122 is likewise carried by the save-all and is adapted to engage the surface of the breast roll so as to collect and discharge into the saveall the white water draining through the initial portion of the forming wire. That portion of the white water draining through the forming board is also discharged into save-all 120 and thence into trough 110. The doctor 122 is pivotally mounted upon the save-all so that it can be swung away from the breast roll when it is desired to remove the breast roll incident to the changing of a wire. Further as indicated in Fig. 3, the save-all pan can be very simply constructed of side angle pieces 124 to which is fastened a bottom plate 125. The construe-'- tion furthermore is of such character that the save-all assembly is directly removable with section 20 of the forming table.

A save-all also extends under the remaining portion of the forming table and likewise discharges collected white water into trough 110. It comprises angles extending longitudinally of the machine to which are attached in any suitable manner, such for instance as by welding, bottom plates 131. The save-all is formed in a plurality of separable parts or sections as indicated in Fig. 6, the adjacent ends of the sections overlapping as shown at 132.

Where it underlies section 22 of the forming table, the save-all is supported on the cross braces 76, and at its lower end is supported upon the trough 110. Where it underlies the shaking section 21, however, it is desirable to support the same in such manner that it has no connection with the shaking section. For this purpose a cross beam 133 extends between the two pedestals 24 adjacent the ends of this section. Consequently the beam 133 remains stationary during the shaking movement pf this section. The save-all is supported from these beams 133 by means of transversely extending angles 134 which are notched as shown at 135 adjacent the inner edge of each 01' the beams so that in this way a proper alignment and firm and rigid support of the save-all is assured. It will further be understood that the parts or sections of the save-all underlying the shaking section 21 may be easily separated from their operative positions and vtelescoped together into the'trough 110 and in this way they are entirely removed and do not interfere with the operation of changing the wire, the n art or,nartsaunderl z iaaaeeot W21 i.

A hand adjusting means 147 mounted on the bracket provides for positioning the slice at the desired longitudinal position. The entire bracket and slice construction is also mounted for vertical adjustment along the way 148, an operating wheel 149 being provided for this purpose. This mounting provides for adjusting the position of the slice both vertically and horizontally.

, A pair of side plates 150 are positioned at each side of the wire and a sealing member 151 located on the outer side of each plate at the base thereof contacts the wire and prevents lateral escape of the stock. A similar sealing member 1511:. ispositioned within the head box for the same purpose. The side plates are. attached to a flange 152 of the head box, an extension 153 being formed on the end wall 141 of the head box and overlying the top of each plate to hold the same in position. Bolts 154 passing through flange 152 and through cooperating right angularly extending flange 155 of the plates secures the plates in operative position. Additional attaching holes 156 are also formed in fl'ange 155 to provide for varying the lateral position of the plates. The plates preferably are formed with bearing means 157 for the deckle roll 158.

Interconnecting means, comprising brackets 159 bolted respectively to the slice plate and to each side plate and having elongated slots 159a and 15% on its right angularly related faces, serves to firmly support the side plates from the slice plate and provides for the desired adjustment of the slice by merely loosening one or the other or both bolts and sliding them in their respective slots simultaneously with the movement of the slice either vertically or horizontally. A suitable foam shower 1590 may also be provided intermediate the first and second slices.

sired state of agitation and that any tendency of the fibersto align themselves is overcome. For this purpose an agitating device is mounted within the head box adjacent the point where the stock'is discharged onto the wire. This device comprises a pair of transversely extending rods 160 located one above the other, upon which are mounted at spaced intervals thin plates or fins 161. The rods are adjustably carried by means of an arm 162 which is suitably slotted as indicated at 163 to provide for varying the vertical position of the agitating elements. Nuts 164 serve to hold the rods in any desired position on the arms. A spring means 165 extending downwardly into the head box is provided on each side thereof, the upper end of the spring means being attached to the upper end of arms 162. The relative construction of the spring means 165 and the arms 162 is such that as vibration is applied to the end of the am as at 166, the deflection will practically all occur in the member 165 and lateral oscillating motion will then be transmitted to the agitating devices with a resultant agitation of the stock. The means for vibrating the device has been indicated generally at .167 and a suitable means.

has been disclosed in detail in applicant's copending application Serial No. 665,114 filed April 8, 1933, to which reference is hereby made. It will be evident therefore that the stock is first placed in such a state of agitation that there is practically no tendency for the fibers to align themselves, and then supplied in this state and v at a controlled rate to the wire.

Between the first and second slice only a rather limited amount of draining action can take place because the space between the breast roll and the forming board is limited and insufficient to permit unimpeded draining of thewater at this point. As indicated there is a throttling pathway 170 through which the water draining through the initial section of the forming wire 1'71 must pass. The breast roll is made of rela tively large diameter and the forming board is positioned closely adjacent thereto and is so formed that there is an area below the wire,

. between the breast roll and the forming board which is of less width than the exposed area of the wire. construction therefore controls and limits thedrainage' taking place through such initial section to no more than the quantity of water that can pass through the throttling pathway, and too rapid drainage is thereby prevented.

Formation therefore is somewhat retarded and stock is continually supplied as the wire approaches the second slice. As the wire passes over the forming board, drainage therethrough is also limited by the spacing of the plates 49 of the board so that no excessive flow of water through the wire is permitted at any point in the initial formative period such as might cause upending of the stock with a resultant fuzzy sheet.

The proper interfelting of the fibers is brought about by first placing them in a state of agitation and disalignment at the time of their introduction onto the'forming wire through the action of oscillating fins 161, and then subjecting the partially formed sheet to a shaking motion at the breast roll, or at the central shaking section of the forming table. or both, accompanied by a controlled rate of draining of the water, particularly at the initial part of the formation period. Thus a high quality sheet of 1.
