3 Claims.
This invention relates to table roll structure for supporting traveling forming wires of paper making machines and includes deflector lips on the journals for the table rolls to prevent water 5 from being thrown back through the wire by the rotating table rolls.
More specifically the invention relates to small diameter table rolls for supporting Fourdrinier forming wires and bearing supports or journals for said rolls having laterally extending deflector lips adjacent the tops of therolls to prevent the rolls from throwing liquid back through the forming wire.
In my copending applications Serial No. 55,753 filed December 23, 1935, now U. S. Patent No. 2,111,833 and Serial No. 80,762 filed May 20, 1936, now U. 8. Patent No. 2,111,835 I have described and claimed small diameter table rolls and attendant mechanism for supporting traveling forming wires. These small diameter-rolls are journaled in bearing supports throughout their entire lengths and extend transversely under the upper run of Fourdrinie'r forming wires for carrying the forming wires and paper v web or stock thereon. Since the small diameter I disturbance.
According to the present invention I now provide deflector lips on the journals or bearing supports for the small diameter'table rolls. These deflector lips extend laterally outward from the ascending sides of the table rolls and define flat surfaces adjacent the tops of the rolls over which the .forming wire passes. The forming wire, however, is not supported by these fiat surfaces but is carried entirely by the rolls.
I am aware that the use of rectangular bars scraping the under side of a forming wire for wiping off a film of water from the wire is known.
- However, these bars as heretofore used have been also used as supports for the wire and, as is obvious, will rapidly wear away the under side of the wire. In installations where the bars are used in combination with table rolls, the same are disposed between the table'rolls in spaced relation therefrom and cannot function to prevent the rolls from throwing water back through the wire.
The improvement provided by this invention 5 therefor includes the use. of a table roll journal to form a deflector lip on the ascending side of a table roll thereby making it impossible for the table rolls to throw water back through theforming wire.
It is then an object of this invention to provide table roll journals with deflector lips extending throughout the length of the table rolls adjacent the ascending side of the rolls. I
A further object of this invention is to provide 15 table roll structure for paper making machines wherein table 'rolls are rotatably mounted in journals coextensive withthe length of the rolls and wherein one 'side of the journals has an integral deflector lip adjacent the tops of the rolls.-
A further object of this invention is to prevent table rolls from throwing water back through the forming wire of a Fourdrinier paper making machine.
Another object of this invention is to provide bearing supports for small diameter table rolls with enlarged lips at the tops thereof on the ascending sides of the rolls.
Other and further objects of this invention will become apparent to-those skilled inthe art from the following detailed description of the annexed sheet of drawings.
On the drawing: Figure 1 is a broken diagrammatic view of the forming part of a Fourdrinier paper making machine showing theupper'run of the Fourdrinier wire supported on table rolls journaled in bearing supports according to this invention.
Figure 2 is an enlarged vertical cross-sectional view taken through the upper run of the form- 40 ing wire shown in Figure 1 and illustrating the table roll structure according to this invention supporting the forming wire.
Figure 3 is a broken elevational view with a part shown in cross section, taken along the line 5 small diameter table rolls I3 disposed between the breast and couch rolls within the loop of the wire. The rolls I3 are journaled in bearing supports composed of members I4 and I5 surrounding the rolls I3 for more than 180 therearound, but allowing the tops of the rolls to contact the under side of the upper run of the forming wire I0. V
The bearing segments I4 have deflector lips I6 extending laterally therefrom adjacent the tops of the rolls I3.
The bearing segments I4 and I5are carried on transverse bars I! which can be carried either from the side frames of the paper making machine, as is more fully described in my application Serial No. 55,753, now Patent No. 2,111,833 above referred to, or from suction boxes as disclosed in my copending application Serial No. 80,762, new Patent No. 2,111,835.
As best shownin Figure 2 the transverse bars I! have finger portions I'Ia of reduced width extending upwardly therefrom. The bearing segments I 4 and I5 have tails or leg portions 14a and 15a fitted against the opposite faces of the fingers Ila.
Bolts I8 extend through the leg portions Ma and I5a of the segments I4 and I5 and through the fingers I'Ia of the bars I1. Heads II! of the bolts I8 are countersunk in the legs I411. The bolts I6 have threaded ends 2|] in screw-thread relation with the legs I5a.
As shown in Figure 3, the bolts having the heads I9 are disposed at spaced intervals across the entire length of the table roll bearings. These bearings support the table rolls across the entire width of the forming wire so that the rolls are journaled under their entire supporting lengths and cannot bend or bow out of shape.
Since the bearings or journals are in two segments, the same can be adjusted toward and away from each other to regulate the size of the journals at various points along the lengths of the rolls. It is obvious that a manipulation of the bolts I8 can.draw the segments I4 and I5 together or space the same apart.
Spaces 2I are provided beneath the rolls I3 and above the fingers I'Ia of the bars I1. These spaces are between the bearing segments I4 and I5 and provide passageways that may be supplied with a lubricating fluid such as water to lubricate the rolls I3.
The bearing segments I4 are positioned on the breast roll sides of the table rolls I3 and since the forming wire travels from the breast roll II to the couch roll I2 along its upper run, the table rolls rotate in a clockwise direction. The bearing segments I4 are thus on the ascending side of the table rolls I3.
The deflector lips I6 forming part of the bearing segments I4 define flat surfaces I6a. directly under the forming wire III and adjacent the tops of the rolls I 3. These surfaces I6a may initially contact the under sides of the wire I0 due to a slight sagging of the wire between the rolls I3. However the rolls I3 actually support the wire I6 and contact between the surfaces I60, and the under side of the wire only occurs during initial operation of the device since any sag of the wire between the rolls I3 will wear away the surfaces I6a. This wearing in of the lip I6 is desirable since it permits the surfaces I6a to be in as close position as possible with the under side of the wire In without actually supporting the wire. If a film or layer of white water is formedon the under side of the wire the surfaces I6a will wipe this layer from the wire and will cause better drainage through the wire.
Since there is no drainage of water through the wire as the same passes over the surfaces I6a the ascending sides of the rolls 'I3 cannot throw water back through the wire. Furthermore since the rolls I3 are mounted in close relationship, water thrown laterally by a preceding roll is deflected downwardly by the lip I6 and cannot roll up through the wire.
In the modification shown in Figure 4, a transverse supporting bar 25 has an elongated passageway 26 extending throughout substantially the entire length of the bar in the center thereof. The passageway or groove 26 is open at the top of the bar.
The top portion of the bar is recessed on both sides thereof as at 21 and 28 to define wall portions 29 and 30 of reduced thickness at the top of the bar.
Bolts such as 34 extend through the walls 29 and 30 and the portions 3 la and 32a of the bearing segments 3 I- and 32 to clamp the bearing segments to the top of the bar 25. These bolts are spaced along the length of the bearing segments at desired intervals. The heads, such as 35, of the bolts are countersunk in the portions 3Ia of the bearing segments 3I. The bolts also have threaded ends 36 tapped through the portions 32a of the bearing segments 32 in screw thread relation with these portions. The bolts thus can be manipulated to adjust the bearing segments 3I and 32 around the table roll I3 and the resilient gaskets 33 permit a drawing of the segments 3I and 32 together. Likewise a loosening of the bolts permits the gaskets 33 to expand and space the bearing segments at any desired distance from the table rolls I3.
A passageway 38 is formed between the bearing segments 3I and 32 beneath the roll I3. This passageway 38 is in communication with the groove or passageway 26 of the bar 25. Liquid can be supplied to the passageway 26 through an opening 39 at one end thereof for flowing upwardly through the passageway 26 and through the passageway 38 around the roll I3 to lubricate the roll or to float the roll in the segments.
The bearing segment 3I has a deflector lip 39 formed on the top thereof defining a flat surface 39a adjacent the top of the roller I3 on the ascending side of the roll.
From the above descriptions it should be understood that this invention relates to deflectors formed adjacent the tops of small diameter table rolls on the ascending side of the rolls. These deflectors prevent--- the rolls from throwing or rolling up white water through the forming wire and thus prevent disruption of fiber arrangements on the wire. The tops of the deflectors extend as close as possible to the wire contacting part of the rolls so as not to leave a gap between the lip and the line of contact of the wire on the roll. Such a gap is undesirable since lubricating water on the ascending side of the roll might be ejected from the roll through the gap into the web on the wire. i
The deflectors prevent water or liquid ejected tangentially by a preceding table r011 from passing back through the wire. The lips or deflectors do not support the wire but are immediately adjacent the tops of the rolls and may initially contact the under side of the wire by virtue of a slight sagging of the wire between the rolls. However the top surfaces of the lips will rapidly wear away and will not be in contact with the under side of the wire for an appreciable length of time.
The table rolls can be made of metal such as stainless steel, Monel metal, brass or the like, or can be made of a plastic composition such as Micarta. If desired, metal table rolls can be rubber covered.
The bearing supports can be metal such as stainless steel, brass or Monel, metal. Likewise the supports can be made of a plastic composition such as Micarta or can be rubber lined.
A desirable adaptation of the invention includes Micarta table rolls mounted in brass, Monel metal or stainless steel bearing supports.
Other desired combinations are stainless steel,'
brass or Monel metal rolls mounted in Micarta or rubber lined bearing supports.
I am aware that many, changes may be made and numerous details of construction may be varied through a wide range without departing from the principles of this invention, and I, therefore, do not purpose limiting the patent granted hereon otherwise than necessitated by the prior art.
I claim as my invention:
