Definitions

  • This invention relates generally to the manufacture of non-woven web or fabric material, wherein the weave or network includes threads or yarns arranged diagonally of the length of the material.
  • Such twill or biased webs or fabrics possess certain advantageous properties, as known to those skilled in the art, such as a remarkable elasticity and deformabilify, in both longitudinal and transverse directions, owing to the diagonal arrangement of the yarns by which it is made.
  • Such twill webs are advantageously used, for example, as reinforcement for tires, as reinforcement and support for artificial leather, plastic sheets and other pliable sheet compound material such as upholstery covering, and so on.
  • said twill webs are cut from conventionally produced fabrics, wherein weft and warp yarns are arranged lengthwise and transversely of the manufactured woven or non-woven networks.
  • Another object of the invention is to provide a method of producing a continuous strip material having parallel side edges and including a network of yarns or threads arranged diagonally to and intercrossing in the space defined by said side edges in superimposed relationship, to form a non-woven twill web.
  • a further object of this invention is to provide a new and advantageous apparatus for continuous manufacture of such non-woven twill web, and capable of continuous mass production thereof; in which reciprocating parts are not included; in which continuously moving spool carrier means are crculated about a plane defined by straight parallel side yarns or cords; and in which the yarns or threads continuously supplied by a plurality of spools supported by said spool carrier are guidely arranged in alternate diagonal directions between and about the parallel side yarns or cords.
  • the invention provides a method of forming a non-woven twill web, which comprises feeding at a given speed two straight parallel essentially inextensible and stress resisting side yarns at locations defining the parallel side edges of the network to be produced, continuously revolving or circulating a plurality of web forming yarn supplies along a path encircling both side yarns, guidely feeding the web forming yarns, at locations essentially adjacent to the plane defined by said side yarns and continuously circulating about said plane-whereby each web forming yarn is caused to be wound about both said side yarns and to be arranged essentially as a flattened helical coil thereaboutmoving the fed web forming yarns together with said side straight yarns in said plane, and joining together the resulting superimposed and intercrossing web forming yarns at a number of locations where said latter yarns intercross.
  • connection to each other of said web forming yarns at said number of locations, and preferably at all points where said yarns intercross, can be made by applying current knowledge of the art, and therefore such step'of the method will not hereinafter be described in detail.
  • suitable binding agents may be used therefor.
  • connection may be performed by combined heating and pressure application, by feeding the produced network between counter-rotating heated roller or conveyor means, for example.
  • the action of heat and/ or pressure may be combined with the use of suitable solvents and/or binding agents, according to the nature of the web forming yarns.
  • the sheet material or materials of the compound article of manufacture may be made use of for securing the intercrossing yarns of the web in their rela tive arrangement. Therefore the said non-woven web may be fed, concurrently with said sheet material or materials, into the nip of counter-rotating rollers or conveyers, according to current knowledge, and bound thereto, by means of binding agents and/ or upon combined action of heat and pressure, according to the nature and character of the combined yarn and sheet material.

  • the apparatus includes guide and feeding means for continuously moving two side yarns 10 and 11, in the direction indicated by arrows A, at a given speed.
  • Such yarns extend parallel to each other and define a horizontal plane therebetween and including these side yarns, and are made of tension resisting material, such as a twine or cord of suitable natural or man-made fibers or filaments.
  • Metallic wire might be made use of for forming said side yarns 10 and 11, if desired.
  • Known means may be used for suitably keeping under tension said side yarns 10 and 11, which are fed in the working portion of the apparatus through tubular parallel components 12 and 13, respectively. 1
  • the means for drawing side yarns 10 and 11 are not shown or described in detail, as such means are well known to those skilled in the art.
  • the draw ing means may be of the type shown and described in Holland US. Patent No. 2,696,243 wherein endless bands 38 supported by and continuously revolving about pulleys 24, 34, 40 and 42 are shown and described for defining parallel side edge components which are moved concurs rently with an unwoven web formed thereabout.
  • Such tubular components 12 and 13 define the shafts of symmetrical sets of pulleys or of gears 14 and 15, respectively, driven at another given speed, and supporting and driving conveyors 16 which are cont1nuously revolved, in direction B for example, at said another given speed, about and essentially parallel to opposite surfaces of the plane defined by said side yarns 10 and 11-.
  • - Conveyors 16 the number of which might of three, for example, act as carrier means for a plurality of Web forming supplies, such as bobbins 17, for example, and of shaped or bent guide tubes 19, each having an inlet located adjacent to a bobbin 17 to receive the yarn supplied therefrom, and an outlet located substantially adjacent the plane defined by said side yarns 10 and 11.
  • a weft holding conveyor is shown as comprising an endless chain structure, the conveying path of which comprises upper and lower straight portions interconnected by substantially circular end portions.
  • each guide tube outlet Upon rotation of said conveyors 16, therefore, each guide tube outlet will continuously travel along a closed path circumscribing the plane, and which includes two straight parallel logs above and respectively below the said plane defined by side yarns and 11, and two short radius half-circle portions having their centers in or essentially in said side yarns.
  • the pitch of said coils will be a function of the ratio of the given speed of feeding in direction A, of side yarns 10 and 11 and the speed of the helically arranged web forming yarns wound thereabout and carried thereby, namely of the speed at which the outlets of guide tubes 19 travel in direction B in the straight legs of the conveyor paths, above and below the plane.
  • both portions 20 and 21 of each formed coil will form an angle of 45 with respect to the said edge forming side yarns 10 and 11 and therefore with respect to the length of the web thus produced.
  • the means for insuring concurrent driving of endless chain conveyors -17, rollers 23 and 24, described hereinafter, and side yarns 10 and 11 have not been shown or described in detail.
  • Such means are known to those skilled in the art of mechanical driving of rotary v components, and preferablycan consist of conventional gear means by which the shafts of gears 14 and 15, the shafts of rollers 23 and '24, and the pulleys (notshown) about which the side yarns are moved, are mechanically interconnected.
  • the gear means can include conventional gear boxes having replaceable or interchangeable gears,.
  • the transmission ratio between the various shafts and therefore providing the desired ratios between the .guide means in direction B may be increased with respect to the speed at which the formed non-woven network is moved in direction A.
  • the portions 20 and 21 of the flat coils formed by each web forming yarns will form a greater angle with respect to the side yarns 10 and 11.
  • a web transversely more rigid will he therefore produced, such web being, however, more resilient as to its longitudinal direction.
  • Such latter result if deemed as objectionable, may be overcome by providing additional parallel straight lengthwise arranged reinforcing yarns, such as diagrammatically indicated at 22 in FIG. 1, for example.
  • Any web forming yarn, as moved outside its respective guide tube 19, will assume its desired coil arrangement about the side yarns 10 and 11, as laid at 18 in the plane or essentially in the plane defined by the side.
  • counterrotating rollers 23 and 24 are located and the web is fed in the nip of rollers 23 and 24, whereby the portions 20 of said web forming yarns, above the said plane, are pressed against the underlying portions 21 to form the desired flat network, wherein the intercrossing diagonal portions 20 and 21 of the web yarns are caused to contact to one another, preparatory to interconnection of the non-woven network components.
  • Such interconnection may be performed by applying current knowledge, by heat process and/or by using proper binding agents. Said interconnection may be performed upon passage between said rollers 23 and 24, for example, or downstream of said rollers and upon passage of the network between conveyors (not shown), for example, for ensuring proper pressure on the superimposed components until setting of the heat and/or binder processed web material.
  • suitable sheet material such as a synthetic film material, may be fed above and/ or below the network formed at 18, if desired, and bound to said network components.
  • the number of the intercrossing portions 20 and 21 in the thus formed non-woven web is obviously a function of the number of spools or other web forming yarn supplies carried by the circulating spool carrier conveyor means, such as embodied by conveyors 16, and the closeness of the network, i.e., the spacing between its components, is a function of the spacing between the outlets of the guide tubes 19.
  • the closeness of the network i.e., the spacing between its components
  • spool carrier assembly might be suitably constructed for supporting and circulating a much greater number of spools and guide tubes, placed close to each other, within the limits or diametral dimension of individual web forming yarns supplies.
