  • the first and second portions 23, 24, 24 have substantially a uniform mesh size.
  • the warp cords 26-31 of the net transition region 19 include warp threads L1 knitted in pairs as chain stitches and longitudinal portions of a plurality of weft laid-in threads L2-L5 knitted with the chain stitches L1. Transverse portions of the respective weft laid-in threads L2-L5 extend in pairs between the warp cords 26-31 and jointly constitute the weft threads 32 of the transition region 19.
  • the warp cords 33-35 of the web regions 20, 20 also include warp threads L1 knitted in pairs as chain stitches and longitudinal portions of a plurality of weft laid-in threads L8, L9 knitted with the chain stitches L1.
  • the adapter 18 thus knitted has the warp cords 26-31, 33-36 thicker than the weft threads 32, 37 so that a pair of longitudinal grooves 38, 38 is defined between every adjacent pair of warp cords 26-31, 33-36 at the opposite sides of the adapter 18.
  • the threads L1, L6, L7 may comprise multifilament yarns made of polyester and the threads L2, L3, L4, L5, L8 may comprise twisted yarns made of polyester.
  • Each thread L9 serves as a connecting thread for connecting two adjacent adapters 18 along their confronting edges, thereby enabling the production of a plurality of laterally connected adapters simultaneously.
  • the connecting threads L9 are made preferably of water-soluble synthetic resin fibers, so that the adapters 18 can be separated by being dipped into water after having been knitted.
  • the adapter 18 can be produced easily on a warp-knitting machine (not shown) in a substantially endless, continuous length which may be severed into pieces of desired lengths by a hot cutting blade or another suitable cutting means (not shown). The cut ends of the respective adapter pieces are prevented from fraying by fusion together of the synthetic resin yarn ends.
  • the warp cords 26 ⁇ 31, 33-36 are composed of the warp threads L1 knitted in pairs as chain stitches and the longitudinal portions of the weft laid-in threads L2-L5, L8, L9 knitted with the chain stitches, the adapter 18 is made per se stable in structure and rigid in construction.
  • each adapter 18 is folded over on itself about the first portion 23 of the net transition region 19 with the reinforcing core thread 46 being held firmly by and between the warp cords 28, 29 of the first portion 23.
  • Each stringer 21 is sandwiched between the web regions 20, 20 of the adapter 18 and then is sewn to the same by two pairs of rows of sewing stitches 44a, 44b, such as lock stitches or double chain stitches, each pair of rows of sewing 44a, 44b extending in and along one longitudinal groove 38, which is devoid of warp cords, across the weft threads 37 of each web region 20.
  • the sewing stitches 44a, 44b are formed by driving a pair of sewing needles (not shown) through each stringer 21 from opposite sides thereof such that a needle thread of the stitches 44a and a looper thread of the stitches 44b appear in each longitudinal groove 38.
  • the warp cords 26, 31, 33-36 serve, in adjacent pairs, to prevent the sewing stitches 44a, 44b from displacing outside the grooves 38 and from being worn out or damaged upon engagement with rigid foreign matter such as rocks, stones and the like.
  • the warp cords 26, 31, 33-36 further serve to grip the stringers 21,21 stably in position.
  • At least the sewing stitches 44a, 44b in each groove 38 are covered with a layer of synthetic resin 45, and more preferably the groove 38 is filled with the synthetic resin layer 45, as shown in Figure 2. With this arrangement, the sewing stitches 44a, 44b are completely protected from any degree of damage, such as loosening, fraying, abrasive wear or the like.
  • the slide fastener 22 shown in Figure 1 has a pair of rows of coupling elements 39, 39 mounted on and along a pair of confronting edges of the stringers 21, 21, respectively.
  • a pair of top end stops 40, 41 is mounted at the upper end of the slide fastener 22 adjacent to a pair of uppermost ones of the coupling elements 39, 39, respectively.
  • the slide fastener 22 further has a bottom end stop 42 mounted at the lower end thereof transversely across the confronting edges of the stringers 21, 21.
  • a slider 43 is slidably mounted on the rows of coupling elements 39, 39 for bringing them into and out of interdigitating engagement with each other to close and open the slide fastener 22 in a well known manner.
  • each adapter 18 of the slide fastener assembly 15 is attached to one of the confronting edges or endmost threads 16 of the net structure 17 by a connecting rope or cord 47.
  • the connecting cord 47 extends successively through the mesh openings in the adapter's third portions 25 and the mesh openings in the net structure's longitudinal edge 16 spirally over and around the warp cords 28, 29, the reinforcing core thread 46 and the endmost threads 16 of the net structure 17.
  • the third portions 25 with the meshes of the largest size allow the connecting cord 47 to pass therethrough with utmost ease, with the result that a simple and time-saving connection is achieved.
  • the slide fastener 22 can be protected against deformation or damage under the influence of severe external stresses because such stresses, when applied on the net structure 17 in the transverse direction of the adapters 18, 18, are taken up and distributed uniformly over the entire length of the slide fastener stringers 21, 21 by means of the net transition region 19, 19 having rectangular meshes of varying sizes defined by the thick warp cords 26-31 and the weft thread pairs 32.
  • the warp cords 26-31, 33-36 have a strength enough to withstand severe external stresses applied to the adapters 18, 18 in the longitudinal direction thereof.
  • the web regions 20, 20 having the smallest meshes, and made compact permit the fastener stringers 21, 21 to be sewn thereto with stability and to a nicety.
  • the adapter's first portion 23, having the thick warp cords 28, 29 and the reinforcing core thread 46 disposed between the warp threads 28, 29, provides a positive connection to each edge 16 of the net structure 17 during a long period of use.
  • Figures 8 and 9 show a modified adapter 50 including a net transition region 51 and a pair of web regions 52, 52 disposed at opposite sides of the net transition region 51.
  • the adapter 50 is substantially the same as the adapter 18 of the foregoing embodiment with the exception that the net transition region 51 includes a pair of second portions 53, 53 each having a pair of rows of rectangular meshes of uniform size.
  • Each of the second portions 53 includes three warp cords 54, 55, 56 and 57, 58, 59 extending longitudinally thereof and a plurality of weft threads 60 which, as described below in connection with Figure 10, have longitudinal portions extending longitudinally of the warp cords 54-56, 57-59 and transverse portions extending in pairs perpendicularly to and between the warp cords 54-56, 57-59 to jointly define therebetween the rectangular meshes.
  • the adapter 50 is composed of a plurality of threads L1 ⁇ L8 each having the same pattern as a corresponding one of the threads L1 ⁇ L8 shown in Figure 6.
  • the adapter 50 is attached to one of the confronting edges of a net structure (not shown) after having been assembled with a slide fastener stringer and a reinforcing core thread, in the same manner as described with respect to the foregoing embodiment.
  • the adapter 50 thus arranged is further advantageous in that lateral tension applied to the net structure is taken up more efficiently and distributed more uniformly through the second portions 53, 53 over the length of the slide fastener stringer than in the case of the adapter 18.
  • An adapter shown in Figures 11 and 12 has a net transition region 62 and a pair of web regions 63, 63.
  • a first portion 64 of the net transition region 62 has a pair of warp cords 66, 67 between which a reinforcing core thread 65 extends.
  • the core thread 65 is held by and between pairs of weft threads 68 extending transversely between the warp cords 66, 67 at longitudinal intervals.
  • Such arrangement is realized by knitting the core thread 65 into the first portion 64 of the adapter 61 as the latter is knitted.
  • the adapter 61 with the core thread 64 knitted therein can be attached to a net structure (not shown) with utmost ease.
  • Figure 13 shows a modified slide fastener assembly 70 comprising a pair of adapters 71, 71 each having a net transition region 72 and a pair of web regions 73, 73 disposed at a common edge of the net transition region 72.
  • a slide fastener 74 includes a pair of stringers 75, 75 secured to the adapters 71, 71 by rows of sewing stitches 76 in sandwiched relation to each pair of the web regions 73, 73, respectively.
  • the slide fastener 74 has a pair of rows of coupling elements 77, 77 mounted on the respective stringers 75, 75 along their confronting edges and a separable bottom end stop 78 so that the stringers 75, 75 can be completely separated from each other when a slider (not shown) is located at the lowermost position adjacent to the separable bottom end stop 78.
  • a pair of core threads 79, 79 reinforces the respective net transition regions 72, 72 arranged for connection to a pair of confronting edges of net structure (not shown).
