Can be transported away from the heating roll 51. Thereby, the heat influence to the slide fastener 11 before transcription | transfer can be prevented.
　また、本実施形態のスライドファスナーの製造装置１０によれば、熱転写フィルム１７が、分離状態の左右のファスナーエレメント列１３の幅Ｗ１よりも広い幅を有する１枚の熱転写フィルムであるため、熱転写フィルム１７が分離状態の左右のファスナーエレメント列１３の双方に同時に加熱押圧される。これにより、各ファスナーエレメント列１３ごとに熱転写フィルムの供給量を調整する必要がなく、熱転写フィルム１７の供給量の管理を容易にすることができる。 Further, according to the slide fastener manufacturing apparatus 10 of the present embodiment, the thermal transfer film 17 is a single thermal transfer film having a width wider than the width W1 of the left and right fastener element rows 13 in the separated state. 17 is heated and pressed simultaneously on both the left and right fastener element rows 13 in the separated state. Thereby, it is not necessary to adjust the supply amount of the thermal transfer film for each fastener element row 13, and management of the supply amount of the thermal transfer film 17 can be facilitated.
　また、本実施形態のスライドファスナーの製造方法によれば、スライドファスナー１１の噛合状態の左右一対のファスナーエレメント列１３を分離する分離工程と、分離状態の左右一対のファスナーエレメント列１３の複数のファスナーエレメント１４に、熱転写フィルム１７の装飾層１７ｂを転写する転写工程と、転写後の分離状態の左右一対のファスナーエレメント列１３を再び噛合する噛合工程と、を備えるため、ファスナーエレメント１４の表面１４ａ、角部１４ｂ、及び側面１４ｃの一部に亘って熱転写フィルム１７の装飾層１７ｂを転写することができる。これにより、スライドファスナーの外観性を向上することができ、外観性の高いスライドファスナーを効率よく生産することができる。 Moreover, according to the manufacturing method of the slide fastener of this embodiment, the separation process of separating the pair of left and right fastener element rows 13 in the meshed state of the slide fastener 11 and the plurality of fasteners of the pair of left and right fastener element rows 13 in the separated state. To provide the element 14 with a transfer step of transferring the decorative layer 17b of the thermal transfer film 17 and a meshing step of reengaging the pair of left and right fastener element rows 13 after transfer, the surface 14a of the fastener element 14; The decorative layer 17b of the thermal transfer film 17 can be transferred across the corner portion 14b and part of the side surface 14c. Thereby, the external appearance of a slide fastener can be improved and a slide fastener with high external appearance can be produced efficiently.
　なお、本実施形態の熱転写フィルム１７の変形例として、図１１及び図１２に示すように、１枚の広幅の熱転写フィルム１７の代わりに、左右のファスナーエレメント列１３にそれぞれ対応する一対の熱転写フィルム１８を使用してもよい。この熱転写フィルム１８は、各ファスナーエレメント１４の幅Ｗ２よりも広い幅を有する。本変形例によれば、１枚の広幅の熱転写フィルム１７を使用する場合と比較して、転写に使用されない部分を減らすことができるので、製造コストを削減することができる。 As a modification of the thermal transfer film 17 of this embodiment, as shown in FIGS. 11 and 12, a pair of thermal transfer films respectively corresponding to the left and right fastener element rows 13 instead of one wide thermal transfer film 17. 18 may be used. The thermal transfer film 18 has a width wider than the width W2 of each fastener element 14. According to this modification, compared with the case where one wide thermal transfer film 17 is used, the portion not used for transfer can be reduced, and thus the manufacturing cost can be reduced.
　さらに、本変形例では、各熱転写フィルム１８の装飾層の色又は模様を異ならせることによって、左側のファスナーエレメント列１３に転写される色又は模様と、右側のファスナーエレメント列１３に転写される色又は模様と、を異ならせることができる。 Furthermore, in this modification, the color or pattern transferred to the left fastener element row 13 and the color transferred to the right fastener element row 13 are made different by changing the color or pattern of the decorative layer of each thermal transfer film 18. Or, the pattern can be different.
　また、本実施形態のファスナーエレメント１４の変形例として、ファスナーエレメント１４は、図１３及び図１４に示すファスナーエレメント１５であってもよい。 Further, as a modification of the fastener element 14 of the present embodiment, the fastener element 14 may be the fastener element 15 shown in FIGS. 13 and 14.
　ファスナーエレメント１５は、ファスナーエレメント１４と同様に、上面１５ａと、上面１５ａの全ての周縁に形成される角部１５ｂと、角部１５ｂから連続する側面１５ｃと、を有する。また、上面１５ａは、ファスナーテープ１２側に形成される平面部１６ａと、平面部１６ａからファスナーエレメント１５の先端に向かって下り傾斜に形成される傾斜部１６ｂと、を有する。なお、ファスナーエレメント１５の先端とは、噛合相手側のファスナーエレメント１５側の端部である。 The fastener element 15 has the upper surface 15a, the corner | angular part 15b formed in all the periphery of the upper surface 15a, and the side surface 15c continuous from the corner | angular part 15b similarly to the fastener element 14. FIG. The upper surface 15a includes a flat portion 16a formed on the fastener tape 12 side, and an inclined portion 16b formed so as to be inclined downward from the flat portion 16a toward the tip of the fastener element 15. In addition, the front-end | tip of the fastener element 15 is an edge part by the side of the fastener element 15 by the side of a meshing partner.
　ところで、このようにファスナーエレメント１５の上面１５ａに傾斜部１６ｂがある場合、噛合状態の左右一対のファスナーエレメント列に熱転写フィルムを使用して色又は模様を転写する従来のスライドファスナーの製造装置では、噛合状態の左右のファスナーエレメント１５の傾斜部１６ｂ間に谷部１６ｃ（図１４参照）が形成されるため、傾斜部１６ｂに転写を行うことが困難である。 By the way, in the conventional slide fastener manufacturing apparatus that uses a thermal transfer film to transfer a color or a pattern to a pair of right and left fastener element rows when the upper surface 15a of the fastener element 15 has an inclined portion 16b as described above, Since a trough portion 16c (see FIG. 14) is formed between the inclined portions 16b of the left and right fastener elements 15 in the meshed state, it is difficult to transfer to the inclined portion 16b.
　しかし、本発明のスライドファスナーの製造装置１０では、分離状態の左右のファスナーエレメント列１３に転写を行うため、図１５に示すように、ファスナーエレメント１５の傾斜部１６ｂにも熱転写フィルム１７の色又は模様を有する装飾層１７ｂを確実に転写することができる。 However, in the slide fastener manufacturing apparatus 10 of the present invention, since the transfer is performed to the left and right fastener element rows 13 in the separated state, the color of the thermal transfer film 17 or the inclined portion 16b of the fastener element 15 is also shown in FIG. The decorative layer 17b having a pattern can be reliably transferred.
　なお、本発明は上記実施形態に例示したものに限定されるものではなく、本発明の要旨を逸脱しない範囲において適宜変更可能である。 It should be noted that the present invention is not limited to those exemplified in the above embodiment, and can be appropriately changed without departing from the gist of the present invention.
