【考案の詳細な説明】
本考案は、テンタ一式複数延伸装置用クリップに関する
ものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a clip for a tenter set multiple stretching device.
更に詳しくは、テンタ一式延伸装置の中心軸に向って開
口した弾性体よりなるスペーサーを、該テンタ一式延伸
装置の上下クリップの片側、あるいは両側に設けたこと
を特徴とする複数延伸装置用クリップに関するものであ
る。More specifically, the present invention relates to a clip for a multiple stretching device, characterized in that a spacer made of an elastic body and opening toward the central axis of the tenter set stretching device is provided on one side or both sides of the upper and lower clips of the tenter set stretching device. It is something.
熱可塑性樹脂フィルムの延伸方法には、一般にテンター
法とインフレ法とがあり、その内テンター法では熱可塑
性樹脂フィルムの両端をクリップで把持しながら加熱延
伸する方法が採られている。Stretching methods for thermoplastic resin films generally include the tenter method and the inflation method. Of these, the tenter method employs a method of heating and stretching the thermoplastic resin film while holding both ends of the film with clips.
更にこのテンター法を発展させた方法として、最近、２
枚以上の熱可塑性樹脂フィルムを同時に把持して延伸す
る、いわゆる複数延伸法が行われるようになってきたが
、単に重ね合わせて把持するだけでは延伸時のフィルム
の自己発熱による融着が発生し、延伸後の分離が困難に
なる等の問題があった。As a further development of this tenter method, two methods have recently been developed.
The so-called multiple stretching method, in which more than one sheet of thermoplastic resin film is held and stretched at the same time, has come to be used, but simply holding them one on top of the other can cause fusion due to self-heating of the films during stretching. However, there were problems such as difficulty in separation after stretching.
そこでこれらの問題を解決するために特開昭５３−８５
８６６号公報にみられるように、把持部組外の２枚のフ
ィルムの間にスペーサーを供給して融着を防ぐ方法や、
特公昭４５−３２１６０号公報のように把持部や把持部
近辺に分離用コードを連続的に供給する方法等が提案さ
れてきた。Therefore, in order to solve these problems,
As seen in Japanese Patent No. 866, there is a method of supplying a spacer between two films outside the grip assembly to prevent fusion,
Japanese Patent Publication No. 45-32160 has proposed a method of continuously supplying a separating cord to the gripping portion or the vicinity of the gripping portion.
しかし、これらの方法はいずれも分離用スペーサーや分
離用コードを連続的に供給してやる必要があり、また延
伸後にそれらをフィルムから分離する工程や、再使用す
る装置が不可欠である等の問題があった。However, all of these methods have problems such as the need to continuously supply separation spacers and separation cords, and the need for a process to separate them from the film after stretching and equipment for reuse. Ta.
本考案者らは、かかる問題につき鋭意研究を重ねた結果
、次のようなりリップを考案するに至った。As a result of extensive research into this problem, the present inventors came up with the following lip.
すなわち、テンタ一式延伸装置の中心軸に向って開口し
た弾性体より成るスペーサーを、該テンタ一式延伸装置
の上下クリップの片側、あるいは両側に設けたことを特
徴とするテンタ一式複数延伸装置用クリップである。That is, a clip for a tenter set multiple stretching device is characterized in that a spacer made of an elastic body and opened toward the central axis of the tenter set stretching device is provided on one side or both sides of the upper and lower clips of the tenter set stretching device. be.
本考案クリップでは、フィルム把持部分のみにスペーサ
ーを入れ、しかも延伸終了後はクリップの開きとスペー
サーの弾性により自動的にフィルムとスペーサーの分離
が行われ、また、スペーサーと把持部とが一体になって
いるので、スペーサーを外部より供給してやる必要がな
く、フィルムとスペーサーの分離工程を設ける必要もな
い。In the clip of this invention, a spacer is inserted only in the film gripping part, and after stretching, the film and spacer are automatically separated by the opening of the clip and the elasticity of the spacer, and the spacer and the gripping part are integrated. Therefore, there is no need to supply the spacer from the outside, and there is no need to provide a process for separating the film and the spacer.
フィルムより自動的に分離されたスペーサー付クリップ
は、テンタ一式延伸機の外側を廻って再びフィルム予熱
部に回帰し、自動的に複数のフィルムを把持して横延伸
あるいは縦横同時２軸延伸を連続的に行うことができる
。The clip with a spacer that is automatically separated from the film goes around the outside of the tenter set stretching machine and returns to the film preheating section, where it automatically grips multiple films and performs continuous horizontal stretching or simultaneous biaxial stretching in vertical and horizontal directions. This can be done in a specific manner.
ここで、本考案クリップの作用効果につき図面により更

幅方向あるいは長さおよび幅方向に延伸が行われる。Here, to explain the function and effect of the clip of the present invention in more detail with reference to the drawings, as shown in Figs. A spacer 2.2' made of an elastic body with an opening facing the central axis of the stretching machine is inserted into the stretching machine, and the outer side is gripped by the gripping parts 3, 3' to hold the thermoplastic resin film 1, 1' in the width direction or length. Stretching is performed in the width and width directions.
クリップの把持手順について述べてみると、まず把持直
前はクリップ４，４′が開いているので、スペーサー２

が分離される。Further, the separation procedure after stretching or heat setting is performed in the reverse order of the gripping procedure, and the clips 4, 4' are opened and the upper thermoplastic resin film 1, the gripping part 3, and the spacer 2°2' are first separated. At about the same time, the spacers 2, 2' return to their initial positions due to their own elasticity, and the lower thermoplastic resin film 1', the gripping portion 3', and the spacers 2, 2' are separated.
