  • the tape main portion 13 has a warp rib region S 16 , and the intermediate region S 17 , the warp rib region S 16 and the identification region S 15 are continuously arranged in a direction directed from the first side-edge 11 to the second side-edge 12 of the fastener tape 10 .
  • the respective warp threads included in the respective regions in the identification region S 15 , the warp rib region S 16 and the intermediate region S 17 repeat passing over a pair of two weft thread portions adjacent in a warp direction. As such, it is suppressed that the number of cam patterns of a loom is redundantly increased and the burden of managing them and the cost of production increase.
  • a structure of the fastener tape 10 such as one shown in FIG. 7 is configured in accordance with a second setting (second cam pattern) of the automatic loom (weave repeat in the entire width of the fastener tape 10 is shown in FIG. 7 ).
  • the identification region S 16 is a warp rib structure having a rib width corresponding to total 4 warp threads, representing that the warp and weft threads are with the main attribute.
  • the fastener tape 10 of FIG. 7 differs from that of FIG. 4 in the structure of the identification region S 15 .
  • the weave repeat of the identification region S 15 of the fastener tape 10 of FIG. 7 is a derived structure from the weave repeat shown in FIG. 5 (similarly a derived structure from a twill weave), representing that the fastener tape 10 is woven by threads certified by second certificate.
  • a cell at coordinates (R 4 ,C 3 ) is filled in lieu of a cell at coordinates (R 2 ,C 3 ); a cell at coordinates (R 8 ,C 3 ) is filled in lieu of a cell at coordinates (R 6 ,C 3 ); a cell at coordinates (R 2 ,C 4 ) is filled in lieu of a cell at coordinates (R 4 ,C 4 ); and a cell at coordinates (R 6 ,C 4 ) is filled in lieu of a cell at coordinates (R 8 ,C 4 ).
  • FIG. 8 ( a ) is a derived structure, i.e. a variant, where 4 filled cells are shifted in position relative to the weave repeat of FIG. 5 .
  • filled cells may be added or deleted additionally or alternatively to the shifting of the filled cells in its position.
  • manipulation can be done to the blank cells.
  • a structure of the fastener tape 10 such as one shown in FIG. 9 is configured in accordance with a third setting (third cam pattern) of the automatic loom (weave repeat in the entire width of the fastener tape 10 is shown in FIG. 9 ).
  • the identification region S 16 is a warp rib structure having a rib width corresponding to total 4 warp threads, representing that the warp and weft threads are with the main attribute.
  • the fastener tape 10 of FIG. 9 differs from those of FIGS. 4 and 7 in the structure of the identification region S 15 .
  • the weave repeat of the identification region S 15 is equal to a weave repeat formed by interchanging the left and right parts of the weave repeat of FIG. 5 with respect to a border between the columns C 3 and C 4 .
  • the weave repeat of the identification region S 15 allows identification of the sub-attribute subdivided from the main attribute.
  • the weave repeat of the identification region S 15 in the fastener tape 10 may be observed through an enlarging optical system and its weave repeat may be identified.
  • the same should be applicable for identification of material and supplier of the threads.
  • the weave repeats of identification region and the sub-attributes are preassociated beforehand, and the correspondence table, i.e. look-up table has been predesigned.
  • the fastener tape 10 may be processed through various steps after woven by the automatic loom. For example, a fastener element is sewn to it, or it is supplied to a dyeing step or to an assembling machine of slide fastener. Various types of fastener tape 10 may be processed in the same machine (e.g. the assembling machine of slide fastener). Therefore, from an aspect of production management, it would be advantageous to allow one to identify by which one of certificates the produced slide fasteners have been certified at the time of their shipping. Particularly, in cases where not just two classification of with and without environmentally friendly characteristic, multiple classification of types of certificate regarding environmentally friendly characteristic is desired, identification and tracking based on the weave repeat of identification region functioning as two-dimensional code would be advantageous.
  • the weave repeat functioning as two-dimensional code may take various forms such as a plain weave structure or a derived structure from plain weave or a twill weave structure or a derived structure from twill weave or a satin structure or a derived structure from satin weave, and may not be restricted to the current number of sub-attributes but can be adapted to addition of sub-attributes in future.
  • the identification region S 15 has an appearance similar to those of other regions in the fastener tape 10 , and does not create a shift in appearance of the fastener tape 10 like the impressing or printing of identification sign.
  • the weave repeat may be a non-warp-rib structure or non-weft-rib structure so that variation of two-dimensional code would be ensured in a limited area.
  • Division based on certification authority, division based on material of thread, and division based on suppliers of thread have been suggested as examples of sub-attributes in accordance with subdivision of environmentally friendly characteristic, but should not be limited thereto. Information such as model number, manufacturing time, and place of manufacturing factory may be divided.
  • a first sub-attribute guarantees degradation within 5 years
  • a second sub-attribute guarantees degradation within 5-10 years
  • a third sub-attribute guarantees degradation in a time period exceeding 10 years.
  • the identification region S 15 may be configured by a structure that looks different relative to one or both regions adjacent thereto.
  • a weave repeat of an adjacent region may include a plain weave or a derived structure from plain weave
  • a weave repeat of the identification region may include a twill weave or a derived structure from twill weave or a satin weave or a derived structure from satin weave.
  • a weave repeat of the identification region may include a plain weave or a derived satin structure from plain weave or a twill weave or a derived structure from twill weave.
  • FIGS. 11-13 show variants of weave repeat of identification region.
  • FIG. 11 illustrates that a weave repeat of 3 rows and 3 columns is a plain weave structure
  • FIG. 11( b ) illustrates that a weave repeat of 3 rows and 3 columns is a derived structure from plain weave
  • FIG. 11( c ) illustrates that a weave repeat of 3 rows and 3 columns is a derived structure from plain weave.
  • two weave repeats selected from FIGS. 11( a )-11( c ) are used, and it is not necessary to use the pure plain weave structure of FIG. 11( a ) .
  • FIG. 12( a ) illustrates that a weave repeat of 3 rows and 3 columns is configured by a combination of a rib (at row R 1 ) extending in the weft direction and a dot (at R 1 ,C 1 )
  • FIG. 12( b ) illustrates that a weave repeat of 3 rows and 3 columns is configured by a combination of a rib (at column C 1 ) extending in the warp direction and a dot (at R 3 ,C 3 )
  • FIG. 12( c ) illustrates that a weave repeat of 3 rows and 3 columns is configured by a combination of a rib (at row R 1 ) extending in the weft direction and a dot (at R 2 ,C 2 ).
  • Plural pattern species can be similarly obtained based on combinations of rib and dot.
  • FIG. 13 illustrates an embodiment where a weave repeat is divided into two regions having a first region to which a first weave type (e.g. plain weave or derived structure therefrom) is allocated and a second region to which a second weave type (e.g. a twill weave or derived structure therefrom) is allocated.
  • a first weave type e.g. plain weave or derived structure therefrom
  • a second weave type e.g. a twill weave or derived structure therefrom
  • a correspondence table (see chart 1 of example of correspondence table) which shows correspondence between a sub-attribute subdivided from a main attribute and a weave repeat of identification region S 15 of fastener tape 10 .
  • the correspondence table is quite simple as shown in hereinafter. It is envisaged that the correspondence table is stored in a computer as a look-up table. Human or image-recognition device may identify a sub-attribute of thread, e.g. a certificate, from a weave repeat based on reference to this look-up table.
  • an automatic loom is set to be in a given cam pattern, and threads (e.g. threads “A”) are supplied to the automatic loom (S 102 ).
  • the automatic loom runs so that a first fastener tape is woven (S 103 ).
  • First identification region e.g. identification region(s) S 15 and/or S 16 shown in FIG. 4 ) in accordance with that given cam pattern is formed in the first fastener tape.

  • a weave repeat e.g. FIG. 5
  • a sub-attribute of second threads e.g. certificate “E”
  • a weave repeat e.g. FIG. 8 ( a )
  • the present identifying method includes a step of identifying one or more identification regions S 15 , S 16 in the fastener tape 10 , and a step of identifying, based on the identified identification region S 15 ,S 16 , that the weft thread 8 and the warp threads 9 are with a main attribute.
