Definitions

  • An apparatus for producing and subsequently longitudinal slitting of a hose-like fabric consisting of a plurality of parallel warp threads and two continuous weft threads intersecting the warp threads and bonded thereto at points of intersection comprises means for advancing the warp threads in the form of a hollow-cylindrical thread layer, and means for advancing a weft thread from each of two stationary weft thread supplies to a respective one of two weft thread guides rotating on a common axis parallel to the axis of the warp thread layer, the weft thread advancing means being arranged so that the weft threads enter the respective thread guides from axially opposite ends of the hollow warp thread layer.
  • the present invention relates to a method for manufacture of net material and other non-woven fabrics, comprising advancing several parallel or wrap threads arranged in a hollow cylindrical layer of threads, helically laying two transverse or weft threads, each supplied from a separate supply, on one face of the layer of warp threads, securing the warp and the weft threads to each other at the points of intersection of the threads, and slitting the hose fabric thus formed.
  • the weft or transverse threads are supplied from spools mounted on a ring rotating around the axis of the layer of warp threads.
  • the ring is in itself relatively bulky, which renders it necessary to keep the number of revolutions of the ring low.
  • a further factor limiting the permissible number of revolutions of the ring is the unbalance of the ring which, inevitably, occurs in practice due to the fact that the individual spools of thread never have exactly the same mass.
  • the number of revolutions directly determines the speed at which the longitudinal threads can be advanced and, thereby, the rate of production which, thus, also becomes relatively low.
  • the necessity of stopping the machine each time a spool is empty, is a contributory factor to the low production rate.
  • the two transverse or weft threads are supplied from stationarily mounted supplies and are fed to the place of laying from opposite ends of the layer of warp threads, and one of the weft threads is advanced on the inside of said layer.
  • the invention has the advantage that the transverse or weft threads may be laid at a considerably higher speed since the thread guides employed for this purpose can be constructed as very light arms which do not have to carry any supply of thread rotating therewith, and it will consequently be possible to increase the rate of production of the fabric manufactured considerably.
  • the thread guides employed for this purpose can be constructed as very light arms which do not have to carry any supply of thread rotating therewith, and it will consequently be possible to increase the rate of production of the fabric manufactured considerably.
  • a doubling of the rate of production is achieved based on the unexpected fact that two threads from stationary supplies can be laid simultaneously around the warp thread layer without interfering with each other or with the associated thread guides, provided that they are fed to the place of laying in axially opposite directions.
  • the invention also relates to an apparatus for performing the method, which apparatus has means for feeding a plurality of parallel warp threads which together form a hollow cylindrical layer of threads,in the longitudinal direction of the threads, two thread guides rotating around an axis parallel to the layer of threads for helically laying two transverse or weft threads, each fed from a separate supply, on one side of the thread layer, means for securing the warp and the weft threads to each other at their points of intersection and means for slitting the hose fabric thus formed.
  • FIGURE of the accompanying drawing illustrates in a somewhat diagrammatical way an apparatus embodying the present invention in lateral elevation, partly in section, whereby only those component parts of the apparatus which are deemed necessary for the understanding of the invention are shown.
  • the apparatus illustrated on the drawing has a base I carrying a frame comprising four columns 2 which, at their top ends, are connected with each other by a frame member 3. As shown, the columns may, in addition, be connected with each other some distance above the base by means of a second frame member 4.
  • An annular supporting cylinder 5 for the net material being manufactured in the apparatus is carried by the intermediate frame member 4 by means of two columns 6 and by horizontal braces 7, of which the drawing shows one.
  • the cylinder 5 may contain means, not shown, for locally heating and/or cooling the cylinder surface with a view to softening and subsequent hardening of the adhesive employed in the production of net material.
  • the warp threads which are designated by 8 in the drawing, extend through guiding means, not shown, upwardly on the inside of the supporting cylinder 5 and across the upper edge thereof, which may be provided with grooves, guiding combs or other means for ensuring a predetermined distribution of the warp threads along the outer circumference of the cylinder.
  • the warp threads 8 are subsequently fed downwards on the outer side of the cylinder 5 and, by means of a mechanism described below, two transverse or weft threads 9 and 10 are laid helically onto the outer side of the parallel warp threads.
  • connection between the warp and weft threads at their points of intersection can be effected by means of an adhesive which, in a manner not shown in greater detail, can be applied to one or the other thread system either prior to the laying of the weft threads or in connection therewith.
  • an adhesive which, in a manner not shown in greater detail, can be applied to one or the other thread system either prior to the laying of the weft threads or in connection therewith.
  • thermoplastic threads it may in certain cases be possible to dispense with a separate adhesive, in that the interconnection can be effected by heating the threads either on the cylinder 5 or by means of heating members mounted outside the cylinder.
  • An apparatus for producing net material by the method generally outlined above is described in US. Pat. No. 3,384,521. In the known apparatus, only one weft thread is employed.
  • the carrying member 11 is hollow and from a spool 14 standing on the base of the apparatus one weft thread 9 extends over stationary guide means 15 which, in the embodiment shown, consist of rollers, but which could be of any suitable shape. From a guide means 25 constructed as an eye and placed immediately above the carrying member 11, the
  • weft thread 9 proceeds through the hollow carrying member and further through guide means 16 on the rotating carrying member 11.
  • the guide means 16 are shown as eyes, but they could be of any other suitable shape.
  • the last guide means 16 is located close to the supporting cylinder 5.
  • the thread 10 may be guided in guide bushings 18, secured to the upper brace 7 and a lower brace 19, respectively. From the topmost bushing 18, the thread 10 passes across the roundedoff edge of the bushing and further through guide means 21 on the rotating carrying member 11.
  • the guide means 21 are shown as eyes similar to the means 16, and the last eye 21 lays the thread 10 around the warp threads 8 advancing along the cylinder 5, by preference midway between the windings formed of the other weft thread 9.
  • one of the two guide means may be adjustable axially or circumferentially to permit a fine adjustment of the mesh width. Such an adjustability may also become expedient if the two said guide means are not mounted diametrically opposite each other but at the same side of the axis of rotation of the carrying member.
  • the net material formed by laying the weft threads 9 and 10 across the warp threads 8 and subsequently securing them thereto, is slit into two nets following the hardening or solidification of the adhesive, which is effected by means of schematically indicated cutting means 11 fitted diametrically oposite each other underneath the cylinder 5.
  • These cutting means may, in a known manner, consist of heated knives or wires which, by melting the successive weft threads, cause them to break.
  • the two nets thus formed may be pulled over suitable guide means, not shown, which assist in flattening the nets, whereupon they are removed from the apparatus via separate discharge rollers 23 to take-up rollers, not shown.
  • An apparatus as claimed in claim 2 comprising means for varying the mutual spacing of said thread guides in the axial direction of the warp thread layer.
  • An apparatus as claimed in claim 2 comprising means for varying the mutual spacing of said thread guides in the circumferential direction of the warp thread layer.
