  • This invention relates to porous fabrics, and more particularly relates to a porous seam and method for making the same by interconnecting the end portions of the fabric to fonn an endless forming structure, such as a Fourdrinier-type belt.
  • a Fourdrinier-type belt is the type of belt upon which paper is made in conjunction with paper making machines. It is generally a woven fabric composed normally of metal warp and shute wires which extend lengthwise and crosswise, respectively. In most cases, a length of the fabric has its ends joined, wire by wire, by brazing to provide the seam or joint necessary to make an endless belt.
  • the type of seam depends upon the mesh of the fabric and the type of paper to be made on its surface. Generally, coarse mesh fabrics are formed into belts with woven or sewed seams, although brazed seams have been employed in some instances.
  • the finer mesh metal fabrics are formed into belts almost exclusively by brazing techniques. Brazing provides a seam which appears as a continuation of the fabric so as not to cause any difierence in the appearance of the paper made thereon.
  • the warp filaments have been cut back and the shutes removed to provide complementary patterns on the warps which are joined together, but wherein specially shaped auxiliary shute filaments were drawn or pushed through corrugations in the warps to complete the seam area.
  • the seam With woven plastic fabrics or semiplastic fabrics, such as plastic warp and metal weft strands, the seam must be strong in tension and flexing, with no objectionable discontinuities in the woven geometry of the fabric. In addition, the seam must have an efficient service life and be economical to produce Heretofore known methods have not incorporated all such specifications necessary to form an acceptable seam.
  • a porous seam for interconnecting the end portions of a porous fabric having polymeric warp filaments is made by cutting adjacent warp filaments on one of said end portions to different lengths relative to one another, cutting adjacent warp filaments on the other of said end portions to different lengths relative to one another to provide a complementary pattern with respect to the first cut end portion, removing the shute filaments between the cut ends of the warp filaments so as to expose, the extensions of said warp filaments, laying a polymeric replacement shute filament transversely of the warp filament extensions and in spaced relation adjacent the nearest remaining shute element on one of said end portions, moving said end portions together so that the cut ends of the warp filaments of said other end portion ride over said replacement shute and into abutting engagement with the corresponding cut ends of the warp filaments of said one end portion, and then weaving a plurality of other polymeric replacement shute filaments transversely across the exposed warp filament extensions of both of said end portions.
  • the joints between the cut ends of the warp filament extensions are then bonded together by an adhesive material, and a further adhesive material is applied to saturate the area adjacent the joints to bond the warp and replacement shute filaments together at their areas of contact, whereafter, excess adhesive material is removed to provide the finished seam, and then the adhesive subjected to thermal curing.
  • FIG. 1 is a fragmentary top plan view of a woven fabric strip with its end portions joined together by the improved seam construction of the invention
  • FIG. 2 is a fragmentary top plan view of the two end portions of the strip ready to be connected together after the warp filaments have been cut and the shute filaments removed, and with the first replacement shute placed in position;
  • FIG. 3 is an enlarged fragmentary side elevation view of the end portions of the fabric strip shown in FIG. 2, but illustrating the intended position of the replacement shute filaments on the right hand end of the fabric;
  • FIG. 4 is an enlarged fragmentary side elevation view looking in the direction of the line 4-4 of FIG. 1;
  • FIG. 5 is a fragmentary vertical section view taken along the line 5--5 of FIG. 4;
  • FIG. 6 is an enlarged fragmentary section view illustrating one method of cutting the ends of the warp filaments in accordance with the invention.
  • FIG. 7 is an enlarged fragmentary section view illustrating another method of cutting the warp filaments in accordance with the invention.
  • FIG. I there is illustrated a length of Fourdrinier type fabric, designated generally at F, with the warp filaments being indicated at l to II and the shute strands or filaments being indicated at 20 to 36, respectively.
  • the fabric has a plain weave in which an evenly spaced pattern of warps and shutes form a series of openings therebetween.
  • the warp filaments are shown (FIG. 3) as overlying one shute filament and underlying the next adjacent shute filament etc., so as to provide a transverse line of knuckles over eve'rgwathershute filament when looking either from the top or bottom side of the fabric.
  • FIG. I the two opposed transverse end portions of the fabric are connected together by the improved seam, designated generally at S, and made in accordance with the invention to provide a composite unitary structure, such as a filter, screen, belt or the like.
  • FIG. 2 illustrates one end portion A, such as the right hand, and the other end portion B,
  • the warp filaments such as I to ill
  • the shute filaments such as 20 to 25 and 31 to 36
  • the heat treat- .nent may be carried out at a temperature of about 200 F. for about twenty minutes to heat set the fabric.
  • the adjacent ends A and B of the fabric are cut, so that the ends of the warp filaments are trimmed square.
  • the warp filaments ll-A to ll-A are substantially parallel and appear to be geometrically continuous with the warp filaments 1-8 to l1-B, as best seen in FIGS. 1 and 2.
  • the warp filaments of each of the respective portions are cut back and the shutes removed in accordance with a predetermined pattern, such as shown in FIG. 2.
  • this may be accomplished by cutting alternate warp filaments on each end portion so that 3 or more shutes lie transversely between the cut and the adjacent terminal edge of the fabric.
  • the cutting may proceed in end portion A by cutting warp filaments l-A, 3-A, -A, 7-A, 9-A, etc., in one plane extending transversely of the fabric, and by cutting adjacent warp filaments 2A, 4-A, 6-A, 8-A, l0-A, etc. in another plane extending transversely of the fabric.
  • the shute filaments within this marginal area are removed so as to form the warp pickets shown in FIG. 2.
  • This sequence of cutting the warp filaments and removal of the shute filaments is similarly carried out with respect to the adjacent end portion B.
  • the cutting on end portion A is taken from the top side of the fabric while the cutting on end portion B is taken from the bottom side of the fabric.
  • the cutting of the warp filaments take place from bottom to top, as viewed in FIG. 2.
  • the end portion A (cut from the top side) may then be laid upon a support, such as an assembly table, and held against movement adjacent its cut edge by suitable means, such as a weight.
  • a polymeric replacement shute, such as 26, may then be laid transversely (FIG. 2) across the trough which is formed by the upper surfaces of the innermost bottom warp knuckles in the pickets of warp filaments, lA, 3A, S-A, etc.
  • the end portion B of the fabric may then be moved into interfitting relationship with the end portion A until the cut ends of the corresponding and complementary warp filaments in each portion abut one another. Such abutment may be assured by perfectly aligning the fabric along one edge.
  • the end of warp filament I-A on the portion A abuts the end of the warp filament l-B on the other portion B of the fabric.
  • the ends of warp filaments 2-B, 4-B, 6-B, 8-3 and 10-8 abut the ends of warp filaments 2A, 4-A, 6-A, 8-A, etc.
  • the end portion B may also be held against movement on the assembly table as by a second weight. It has been found, for example, that magnetic metals weights laid on the surface of the fabric near the seam area are effective for holding the ends of the fabric during the seaming operation.
  • additional replacement shute filaments of polymeric material are progressively woven into place.
  • this may be achieved by hand picking into place a second replacement shute, such as 27, by progressively lifting the pickets on the end portion A and sliding the shute into place.
  • the shute filament 27 is picked under warp 1-A, over warp 2-B, under warp 3-A, over warp 4-B, etc., until the shute is placed beneath all the warps in the row.
  • the fabric including the end portions A and B, may then for convenience be lifted into a generally vertical position, whereupon, a third polymeric replacement shute, such as 28, may be hand woven (i.e., picked) into place, but from the bottom side of the fabric.
  • a third polymeric replacement shute such as 28, may be hand woven (i.e., picked) into place, but from the bottom side of the fabric.
  • the shute 28 may be picked over warp I-A, under warp 2-B, over warp 3-A, under warp 4-B, etc.,
  • a fourth polymeric replacement shute filament such as 29, may then be picked into place while the fabric is still in the vertical position, but from the top side of the fabric. For example, the picking would proceed under warp l-A, over warp 2-B, under warp 3-A, over warp 4-B, etc.
  • a fifth polymeric replacement shute such as 30, may then be picked into place while the seam area remains in the vertical position, but from the bottom side of the fabric by picking the shute over warp l-A, under warp 2B, etc., in the same manner described in connection with the third shute 28.
  • an effective seam area is provided, except for the interlocking joint between the corresponding cut warps of both end portions, and which may be achieved without the need for specially shaped shutes and/or auxiliary drawing techniques for inserting the shutes into the seam area.
  • the width of the seam area A is actually very narrow as compared to the actual dimensions of the fabric which may vary dependent on such factors as the size and/or number of shute filaments employed.
  • a less number such as 4 or 3, may also be employed, as desired.
  • the cut is made between shutes 31 and 40 (previously removed) by slicing through the warp filament, such as l-A, at approximately its midpoint, as at 54, as it slopes upward from the bottom toward the top of the fabric and at an angle B, such as 60 with respect to a line extending perpendicular to the general plane of the fabric. Accordingly, to insure that the mating ends of the warp filaments will abut flatly against each other, the angle of cut on one filament preferably supplements the angle of cut on the mating filament end.
  • the cut on the long warp pickets can also be made by a hand shears by making the cut supplementary to the angle of cut for the short warp pickets, such as 2A, 4-A, etc., as aforesaid.
  • the aforementioned second cut which may be employed may be achieved, as shown in FIG. 7, by placing the cutting tool T (blade edge) at the point, such as 52, at which the upper surface of the bottom warp knuckle 55, of the warp l-A meets the peripheral surface of the shute filament 40.
  • the cutting tool T blade edge
  • the cut can be made at an angle A of approximately 45 with respect to a line which extends perpendicular to the general plane of the fabric. This provides a cut thro u'glifirewaip fiiament, such as l-A, which is hidden from view when looking from the top side of the fabric.
  • the warp filaments which are used for forming the short pickets on the end A may be cut in the manner described in connection with the formation of the short pickets on end B, and as illustrated in either FIG. 6 or 7, while the ends of the long pickets on end A are cut at an angle supplementary to that of the short pickets on end A.
  • the surfaces of the filaments which comprise the seam and a portion of the body of the fabric on each side of the seam may be treated to enhance their adhesive characteristics.
  • the surface of the filaments may be roughened by blasting the surface with small particles of abrasive material, such as micron-sized silicon carbide. This method may be carried out following the removal of the shute filaments and after the warp pickets have been cut at their ends.
  • both the top and bottom surfaces of the seam are treated in this manner so that all exposed surfaces of the warps are roughened.
  • This treatment may also be employed after assembly (meshing) of the end portions A and B so as to increase the adhesability of all the filament surfaces in the region of the seam and to remove any soil or the like deposited during the seam assembly.
  • a suitable electrical corona discharge treatment may be employed. By either method, it has been found that scam strengths improve by about 25 percent as compared to seam strengths as derived from adhering untreated seams.
  • the warp filaments and the replacement shute filaments for the seam are comprised of a polymeric material.
  • such filaments are formed of a polyester resin, such as polyethylene terephthalate.
  • a polyester filament having a diameter of 0.032 inch is available from the Goodyear Polyester Products Department under the trade name, VITEL, type VFR 1676, or a 0.025 millimeter polyester filament available from the American Hoechst Company under the trade name TRIVERA, or a 0.020 millimeter polyester filament available from the American Hoechst Company under the trade name TRIVERA, type P, may be employed for the warps.
  • the shute 0.020 millimeter polyester filaments available from the American Hoechst Company under the trade names TRIVERA, type PR and TRIVERA, type PRN, may be employed.
  • the polymeric material for the filaments of the seam have a low thermal shrinkage, such as about 1 percent shrinkage by length at a temperature of about 212 F.
  • the abutting ends of the warp filaments are bonded to one another.
  • the bonding may be achieved by the application of an adhesive by means of a tool, such as a hypodermic syringe needle, which, for example, may have an 0.006 inch ID. and a 0.013 inch OD.
  • the needle may be force fed by a micro-metering pump of the type available from the Pyles Equipment Company.
  • the needle may be mounted on a suitable support (not shown) and may be guided along a row of joints in the seam pickets so as to disperse a metered amount of adhesive to provide the joints, such as 54, between the free cut ends of the opposed warp filaments, as seen in FIGS. 1 and 4.
  • the other row of joints, as at 56, is similarly treated so that all the joints are filled with the adhesive and without filling the openings in the fabric adjacent the bond.
  • the adhesive material employed will depend on the materi al of which the warp and shute filaments are formed to provide a compatible and strong adhesive bond therebetween.
  • polyester filaments at least three classes of adhesive material have been found to be useful including (1) polyester resin cured with a free radical catalyst, (2) phenoxy resin cured with free isocyanate prepolymeris, and (3) vinyl acetate maleic acid ethylene terpolymer cured with urea formaldehyde.
  • the curing agents or catalysts are added to the resins to cause them to become tough, strong and water resistant after curing.
  • the adhesive material applied may be equal weights of a polyester resin (available under the trade name MOBAY R-l2) and trimethylolpropane adduct of tolylene di-isocyanate (available under the trade name MOBAY CB-75).
  • the applied adhesive is preferably heated to a temperature sufiicient to cause a complete cure within a time period suitably short for production purposes. It is preferred that the temperature never be equal to or greater than the temperature employed to thermally stabilize (heat set) the warp pickets prior to cutting thereof.
  • the seam area remains stable throughout the adhesive cure so as to insure proper strength characteristics at the joints. Moreover, any thermal movement and/or shrinkage of the pickets during the curing period would disrupt the bonding effect which takes place during the cure.
  • the cure may be carried out at a temperature of about 175 F. and at a time between about 3 to 4 hours, for example. The joints may then be allowed to cool or cooled to ambient temperature, as desired.
  • the entire area of the seam S is then preferably saturated with an adhesive material.
  • the excess adhesive material which fills the mesh may be blown off, such as by compressed air, at about lbs. p.s.i. so that there is provided a thin film of material adhering to the exposed surfaces of the filaments. This remaining film of material is sufficient to provide a filleting, as at 58, around the crossovers of the warp and shute filaments, as seen in FIG. 5.
  • the warp and shute filaments are further adhered to one another so as to increase the overall strength of the seam.
  • Such curing of the saturating adhesive may be achieved by the addition of a suitable catalyst of the types aforementioned and/or by the application of heat at a temperature which is also applied below the thermal stabilizing (heat set) temperature for the seam.

  • saturation of the seam following the bonding of the joints prevents movement of the warp pickets so as to eliminate geometric discontinuities, thus effecting a better quality seam.
  • the invention was carried out by making a 70 by 58 mesh fabric of polyester warp and shute filaments which were heat set at 275 F. for 5 minutes.
