Definitions

  • ABSTRACT A papermakers cloth or a cloth for similar purposes having interlacing means at both transverse edges of the cloth in the shape of loops which, when interlocked form a continuous joint in said cloth.
  • the locking loops are formed by weaving the weft yarns in two different layers about one or two temporary threads positioned at the edge or edges of the warp, or alternatively, at the centre thereof, whereby the locking loops will be located cornealy between the upper and the lower surfaces of the weave.
  • the loops are there- I after heat treated and the temporary thread removed.
  • the invention also concerns a method of producing said loops.
  • Jointed cloths maybe divided into two groups, viz. those that permit mounting in a continuous condition in the machine but for other reasons are not woven as tubular fabrics, and those that-necessarily must be open (unspliced) during mounting.
  • the former group generally permit jointing to be carried out during the manufacture', giving a joint which in appearance and other characteristics on the whole agrees with the rest of the cloth.
  • the cloths that need be open when delivered to the site of use and subsequently be jointed during mountingmust be provided with locks at both cloth ends.
  • a lock for this purpose .must fulfil the following demands: 1.
  • the lock must be as durable as the rest of the cloth and as resistant against mechanical, chemical and thermal decomposition.
  • the lock parts must be easy to join together during mounting to ensure that the operation standstill is minimized at cloth replacements. 3. It must be easy to form the lock during the manufacture of the cloth proper. 4. In certain fields of usage there are also demands on minimum marking, in additionto which the lock must have the same openness as the rest of the cloth.
  • the locks most commonly used are those employed for dryer cloths and certain felt cloths, and denominated mechanical locks. These locks constitute so called fastenerlocks similar to those used when splicing driving-belts. The hooks 'aredriveninto the material itself or into separate locking straps which are then mounted on the cloth proper. Such locks are useful for instance for dryer cloths, although they have certain deficiences. In other cloths, for instance those intended for certain felts oras forming wires for the manufacture of fibreboards, locks of this kind cannot be used on account of the excessive marking they cause. For these purposes cloths made from synthetic resin filament yarns, usually monofilaments, are completely prevalent.
  • the lock is made from loops formed from the samematerial as that making up the cloth or from a separate thread integrated with the cloth.
  • An example of the former lock is disclosed in the Swedish than the joint disclosed in the Published Application No. 322,980, primarily because the weaving thereof cannot be performed until the manufacturer has received a particular order from the user and because the length of the cloth is limited in dependence on the width of the loom.
  • the present invention relates to acloth having a lock which is suitable for use in the positions of use enumerated above andsimilar positions.
  • the lock consists of a number of loops formed alternatingly at the two mutually opposite transverse edges of the cloth from one common thread which also is a part of the longitudinal threads of the cloth (weft threads).
  • the characterising feature of the invention is that the loops are positioned in their entirety between the two planes forming the upper and the lower faces of the cloth.
  • thewarp When weaving with comparatively rigid yarns, such as monofilaments, thewarp commonly forms sinuous threads in the loom, these threads coiling or twisting about the relatively straight weft threads.
  • the warp will form the surface layers of the cloth and because the warp thread loops in a multileaved weave will not be positioned in a longitudinal row of uniform loop shape the warp cannot form the locking loops in accordance with the inventionn as these will be in a position above at least one of the surfaces of the cloth. It is thus necessary that the locking loops are formed from the weft yarn which, however, on account of its straightness is not very suitable for separate splicing outside the loom.
  • the loops are, in accordance with the invention, formed directly in a loomsuch that one and the same thread without interruptions is used to form a series of loops alternatively in the two edges of the cloth while the same thread simultaneously constitutes a longitudinal thread in the finished cloth.
  • the present invention also concerns a method of manufacturing a cloth having the loops as indicated above.
  • FIG. 1 is a vertical transverse section taken in parallel with the extension of the warp threads in a double layer weave
  • FIG. 2 is section along line IIII of FIG. 1,
  • FIG. 3 illustrates on an enlarged scale one marginal portion of the weave provided with the locking loops in accordance with the invention
  • FIG. 4 is an end view which in the scale of FIGS. 1 and 2 illustrates the end portions of a weave being manufactured in accordance with the teachings of the invention with locking loops at both ends of the weave,
  • FIG. 5 is a view similar to the one illustrated in FIG. 4 but on a reduced scale and shows schematically the extension of only those threads of the weave which in the-position of use thereof constitute the longitudinal threads, including the locking loops thereof,
  • FIG. 6 is a similar view to the one shown in FIG. 4, the locking loops being, however, positioned in the upper cloth of the weave,
  • FIG. 7 is a similar view to the one shown in FIG. 4 but illustrates the provision of locking loops at both edges of both the upper and the lower cloth
  • FIG. 8 illustrates schematically and in a perspective view the course of a weftthread as laid about a border thread to form the locking loops and the extension thereof in relation to one of the warp threads.
  • the cloth comprises warp threads 1, 2, 3', 4 extending in the plane of the drawing, and weft threads 5, 6, 7, 8 extending normally relatively the plane of the drawing, divided into two separate layers.
  • the warp threads 1, 2, 3, 4 consist of sinuous or wave-like threads which are. twisted about the comparatively straight weft threads 5, 6, 7, 8. If these threads were joined in a manner similar to the one described in the above referenced Swedish Published Application No. 322,980 the result would be that the loops would extend partly beyond the two surfaces 9 and 10 of the wire.
  • FIG. 2 illustrates the embodiment of the straight weft threads 5, 6 in the sinuously extending warp threads 1, 2, 3, 4.
  • the two weft threads 5 and 6 comprise one common thread 11 which thread forms the locking loop 12 at the edge of the cloth said loop being positioned entirely between the two planes 13, 14 forming the surface of the cloth.
  • the locking loops are manufactured at'the same time as the cloth itself, as is illustrated in principle in FIGS. 4 and 5.
  • the warp threads 1, 2, 3, 4 of the upper cloth and the warp threads 15, I6, l7, 18 of the lower cloth are threaded through the loom comb and reed in the conventional manner.
  • a border thread 19 of the cloth is threaded at the far end of one edge, for instance the right one with reference to FIG. 4, is threaded a border thread 19 of the cloth.
  • the two weft which is coarser than the rest of the threads and preferably consists of a synthetic resin monofilament having a diameter of 2 mm.
  • This single thread is controlled completely individually as compared with the rest of the threads of the warp.
  • thread 1 is in lifted position while threads 2, 3, 4 of the upper cloth and all threads 15, l6, l7, 18 of the lower cloth and border cloth 19 are in lowered position.
  • threads 1, 3, 4 of the upper cloth are in lifted position while the rest of the threads are in lowered position.
  • the first two weft threads are woven into the upper cloth.
  • the third and the fourth weft threads pass through the lower cloth around the border thread 19 and therefrom pass back through the lower cloth.
  • the thread forms a so called turning fold in accordance with the common practice in tubular weaving.
  • the border thread 19 has been moved to the centre of the upper cloth.
  • the weft thread passes through one half of the upper cloth, around the border thread and thereafter back through the lower cloth and the second half of the upper cloth, around the border thread and back through thesame half of the upper cloth and the entire lower cloth.
  • the border thread extends in the centre of the upper cloth, and each edge of the cloth consists of saidturning fold known from the tubular weaving technique.
  • two shuttles are used.
  • Two border threads 19" are positioned ateach selvage of the weave.
  • One shuttle passes through the upper cloth, around the left border thread 19 and back through the upper cloth.
  • the second shuttle passes through the lower cloth, around the right border thread 19" and back through the lower cloth.
  • the weave thus comprises two locks.
  • the cloths may be used interconnected or individually. If desired, only one of the cloths may be produced, making use of one shuttle only.
  • the loops are exposedto a heattreatmentto set them in position before removal of the border thread.
  • the weft threads extend in pairs in planes which are at a right angle relatively the surfaces threads, which together make up the same pair, correspond to one single thread only from the point of view of openness and consequently it becomes possible to double the weft density in a cloth of this kind as compared with for instance a single-layer cloth without impairing the openness. a consequence, the number of loops is likewise doubled and thus the strength greatly improved.
  • a flat woven double layer cloth having surfaces forming two planes and terminating in two transverse edges, having warp and weft threads, for use in the paper making and cellulose industries, particulary as a cloth for dewatering and filtering and as a forming fabric for cellulose and course paper and as a press felt,
