Definitions
- PAPERMAKER'S FABRICS The invention concerns papermaker's fabrics and has more particular reference to a method for the manufacture of a seamed endless structure for use as papermachine clothing or as a base material therein.
- the warp yarns in the weaving loom extend in the machine direction of the eventual papermaker's fabric, and the fabric is made endless by, for example, weaving weft-free warp yarns at the respective fabric ends back into the fabric to form warp loops thereat which extend in the machine direction and by introducing a pintle wire into the tunnel formed by the interdigitated loops of the respective fabric ends thereby to join such ends.
- the warp yarns in the loom are the cross-machine direction yarns of the papermaker's fabric.
- the method comprising the steps of providing a fabric of plural, superimposed layer configuration throughout substantially the full longitudinal extent thereof and having fold regions at the respective opposite ends thereof, and removing cross- machine direction yarns from said fold regions to leave machine-direction loops thereat.
- the superimposed fabric layers are two in number.
- the superimposed fabric layers are defined by a laid-flat fabric of endless-woven configuration.
- a textile batt is needled to at least one side of the endless base material.
- the loops of the respective fold regions may be brought into mutual interdigitated relationship directly to receive a pintle wire in the tunnel formed thereby, thus to form a seam or may be engaged with a spiral coil itself intended to form the seam or a part thereof.
- the invention also includes a papermaker's fabric or base fabric therefor made in accordance with the method as aforesaid.
- FIG. 1 to 3 respectively show successive stages in the production of an endless base material for use in a papermaker ' s fabric and comprising a flat-woven single layer structure;
- Fig. 4 is a view corresponding to Fig. 3 and shows an endless-woven base structure having machine direction loops provided therein in accordance with the invention
- Figs. 4A and 4B are enlarged sections taken longitudinally of the structure shown in Fig. 4 at locations A and B, respectively;
- Fig. 5 shows the seam region of base fabrics of the kind shown in Figs. 1 to 3 and Fig. 4, a textile batt having been applied to each face thereof.
- a base material for use in the manufacture of a papermaker's wet felt comprises a flat- woven fabric 11 of open weave construction having a length approximately equal to twice the length of the intended end product, that is to say of the papermachine clothing.
- the free ends 12, 13 are folded over to define a two-ply structure having fold regions 15, 16, the free ends being brought into substantial abutment as shown in Fig. 2.
- the free ends 12, 13 of the initial flat-woven fabric 11 are sewn to the adjacent fabric ply 21, as at 22 in Fig. 2, whilst the two fabric plies 21, 23 are stitched together in fold regions 15, 16 in closely spaced disposition relative to the loops 17, 18, as is shown at 24.
- Figs. 4, 4A and 4B in which like reference numerals to those of Figs. 1 to 3 are used for the same or similar parts, an endless-woven fabric is laid flat, and the fold regions 15, 16 between the resultant overlying plies thereof are brought together as shown in Fig. 4.
- Cross-machine direction yarns that is to say warp yarns in the loom, are removed from the fold regions to give outwardly extending loops 17, 18 as before, the plies being sewn together in closely spaced disposition relative to the loops, as at 24.
- the structure On interdigitation of loops 17, 18 and the insertion of a pintle wire, the structure is brought back into endless form.
- machine direction yarns In the event that the machine direction yarns are to form loops at the respective fabric ends for interdigitation and receipt of a pintle wire, such machine direction yarns will ordinarily comprise monofilament yarns. However, if spiral coils are to be applied to the weft free zones and the spirals at the respective fabric ends, rather than machine direction yarn loops, are interdigitated to receive a pintle wire, ⁇ then such machine direction yarns may, for example,
- the cross-machine direction yarns may take the form of, for example, monofilament, cabled monofilament or multifilament yarns.
- a textile batt 25 is needled to each face of the endless structure, 10 be it a structure in accordance with the principles of Figs. 1 to 3 or of Figs. 4, 4A and 4B, the needled batt being slit in register with the seam at the paper side, as at 26, and cleared in relation to the seam at the machine side, as at 27, to provide access thereto.
- the 15 needling operation brings the batt at each face into coherent and homogeneous form through the base structure, and serves also to secure the individual plies of such base structure together.
- the invention is concerned primarily with the 20 production of a base structure for combination with a textile batt in the manufacture of a wet end fabric, it is to be understood that the invention is also of relevance to the production of a two-ply papermaker's fabric comprising a flat-woven or an endless-woven 25 structure brought into endless form in accordance with the method herein disclosed.
- the free ends may be secured together, and, if required, to the adjacent ply at the inner face of the eventual papermaker's fabric, by removing cross-machine direction yarns at such ends, interdigitating the fringed-out machine direction yarns and securing those yarns together by means of a thermosensitive adhesive film or tape interposed between the fringed-out ends and the adjacent ply and activated in appropriate manner.
- the ends may be secured to the fabric ply by employing a powder bonding technique or by sewing.
- overlying fabric plies are said to be sewn together adjacent the loops and in the region of the abutting fabric ends. It is to be understood that such plies may also be sewn together at any other position or positions intermediate the loops.
