【考案の詳細な説明】
本考案は糸条を並列して延伸熱処理する装置に関し、多
数本の糸条を一度に安定して処理することができ、並列
の中央と両側の間に処理効果の差を生せしめない糸条の
並列延伸熱処理装置を与えるものである。[Detailed description of the invention] The present invention relates to an apparatus for drawing and heat-treating yarns in parallel, which can stably process a large number of yarns at once, and allows the processing effect to be maintained between the center and both sides of the parallel yarns. This provides an apparatus for parallel stretching and heat treatment of yarns that does not produce any difference.
従来の糸条の並列延伸熱処理装置は接触型プレートヒー
ターあるいは平滑面をもって囲まれた横断面偏平な加熱
通路を有する非接触型ヒーターの前後に糸条供給ローラ
ーと糸条引取りローラーとを配してなるものであって、
前者はヒーターの温度分布が均一であれば並列の中央と
両側とで殆んど差のない処理効果が得られるが、糸条が
汚れたり、表面に傷付いたりし易い欠点を有し、後者は
糸が汚れたり、表面に傷付いたりすることは少ないが、
並列の中央と両側とで処理効果に差が出たり、両側にお
いて並列糸条が隣同志接触干渉を起し、両側で糸条切断
が起り易いという欠点を有する。Conventional yarn parallel stretching heat treatment equipment has a yarn supply roller and a yarn take-up roller arranged before and after a contact type plate heater or a non-contact type heater having a heating passage with a flat cross section surrounded by a smooth surface. It is something that
The former provides a treatment effect with almost no difference between the center and both sides of the parallel arrangement if the temperature distribution of the heater is uniform, but it has the drawback that the threads are easily soiled and the surface is easily scratched. The threads are less likely to get dirty or the surface gets scratched, but
There is a disadvantage that there is a difference in the processing effect between the center and both sides of the parallel line, that the parallel yarns contact and interfere with each other on both sides, and that yarn breakage is likely to occur on both sides.
本考案は後者について上記欠点のない延伸熱処理装置を
得べく鋭意研究の結果なされたものである。The present invention was made as a result of intensive research in order to obtain a stretching heat treatment apparatus that does not have the above-mentioned drawbacks.
すなわち、従来の非接触型熱処理装置にあっては糸条の
走行に伴なう随伴気流は並列の中央部では比較的抵抗を
受けることが少なくて早く、並列の両側では抵抗を受け
て相対的に遅くなっており、従って送行糸条との相対速
度差は中央部で少なく、両側で大きい。In other words, in conventional non-contact heat treatment equipment, the accompanying airflow accompanying the running of the yarn is relatively fast at the center of the parallel line, where it receives relatively little resistance, and on both sides of the line, where it receives resistance and relatively Therefore, the relative speed difference with the feeding yarn is small in the center and large on both sides.
そのため中央部の走行糸条は随伴気流に妨げられて受熱
効率が相対的に低く、両側の糸条は随伴気流に比較的妨
げられないから受熱効率が高くなって、中央部と両側と
に処理効果の差を生じ、また両側の糸条は隣同志接触干
渉し易い。Therefore, the running yarn in the center is obstructed by the accompanying airflow and has a relatively low heat receiving efficiency, while the yarns on both sides are relatively unhindered by the accompanying airflow, so the heat receiving efficiency is high, and the yarns are processed in the center and both sides. This results in a difference in effectiveness, and yarns on both sides tend to contact and interfere with their neighbors.
そこで、随伴気流の糸条に対する相対速度が中央部と両
側とで同じになるようにして従来の欠点を解消したのが
本考案の装置である。Therefore, the device of the present invention solves the drawbacks of the conventional method by making the relative speed of the accompanying airflow to the yarn the same in the center and both sides.

並列延伸熱処理装置にある。The present invention provides a drawing heat treatment apparatus comprising a non-contact type heat treatment apparatus having a heating passage with a flat cross section through which yarns are passed in parallel, and a yarn supply roller and a yarn take-up roller arranged before and after the apparatus. A parallel drawing heat treatment apparatus for yarn is characterized in that a yarn passage is opened on the yarn inlet side of the heating passage and air blowing nozzles with larger openings are provided on both sides of the heating passage so as to sandwich the parallel yarn.
