本発明はベルトに関し、更に詳しくは、製造が
容易で、かつ補強コードの剥離等の発生し難い耐
久性に優れたベルトに関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a belt, and more particularly to a belt that is easy to manufacture and has excellent durability and is resistant to peeling of reinforcing cords.
従来、ベルトは織布を補強材として用い、この
織布の上下面をゴムのカバー層で覆うようにした
もの、或いは、二つのゴム層の間にコードを配列
させて加硫成形したものなどがある。
Traditionally, belts have used woven fabric as a reinforcing material, with the upper and lower surfaces of the woven fabric covered with rubber cover layers, or belts have been vulcanized and formed by arranging cords between two rubber layers. There is.
しかし、前者の場合は、織布をベルトの周長や
幅に合わせて予め一定の長さや幅に裁断しておく
工程が必要があり、手間が掛かつていた。また、
使用期間中、ゴム層と織布との間に剥離現象が起
こり易く、耐久性が問題になつていた。また後者
の場合も、コードとゴム層とが直接接着するため
剥離の問題があり、耐久性の面で問題があつた。 However, in the former case, it is necessary to cut the woven fabric to a certain length and width in advance to match the circumference and width of the belt, which is time-consuming. Also,
During the period of use, peeling phenomenon tends to occur between the rubber layer and the woven fabric, posing a problem in durability. In the latter case as well, since the cord and the rubber layer are directly adhered to each other, there is a problem of peeling, which causes problems in terms of durability.
〔発明の目的〕
本発明の目的は、製造が容易で、かつ剥離等が
発生し難い耐久性に優れたベルトを提供すること
にある。[Object of the Invention] An object of the present invention is to provide a belt that is easy to manufacture, is resistant to peeling, and has excellent durability.
上記目的を達成する本発明は、コードに撚り加

The present invention achieves the above object by forming the yarn before being twisted into a cord into an endless annular belt without using a weft, and impregnating the periphery with a resin binder and fixing it together. It is characterized by comprising a reinforcing layer.
このように、ヤーンをエンドレスな環状帯状体

で、ゴムとの接着の場合のように剥離することは
なく、耐久性に優れたベルトを得ることができ
る。 In this way, the yarn can be formed into an endless annular band by a simple process of winding it around a forming drum and applying a resin binder. In addition, since the yarn is impregnated with a resin binder and integrated into the yarn before being twisted into a cord, it does not peel off like in the case of adhesion to rubber, making it possible to obtain a belt with excellent durability.
以下、図を参照して本発明の構成につき詳細に
説明する。 Hereinafter, the configuration of the present invention will be explained in detail with reference to the drawings.

は補強層７のみからなるベルトを示している。 1 to 3 show cross-sections in the width direction of the belt of the present invention. Fig. 1 shows a belt in which a cover layer 4 is fixed to the upper and lower surfaces of a reinforcing layer 7 via an adhesive layer 3, and Fig. 2 shows a belt in which a cover layer 4 is arranged on only one side of the reinforcing layer 7 via an adhesive layer 3. FIG. 3 shows a belt consisting only of a reinforcing layer 7.
上記補強層７は、その幅方向に多数本のヤーン

とにより、これのみでベルトとなり得る。 The reinforcing layer 7 is constructed by arranging a large number of yarns 8 in parallel in the width direction without using wefts, and impregnating and fixing the periphery with a resin binder. This reinforcing layer 7 is a flexible band-like material, and by being formed into an endless ring shape, it can be used as a belt by itself.

製品が得られる。 FIG. 4 explains the manufacturing process of a light conveyor belt that requires dimensional accuracy and stability, and the reinforcing layer 7 is made of glass yarn and polyurethane resin. First, the roller 10 of the molding machine,
10', a cover layer 4 made of polyurethane is wrapped endlessly, and a fifth layer is wrapped on top of this cover layer 4.
As shown in the figure, urethane resin is applied as a resin binder while winding the yarn 8 endlessly to form an annular band at a constant density. Once this urethane resin is cured, belt molding is completed. A product is then obtained by removing the belt from the belt forming machine.
また、ヤーン８の巻き付け方としては、ヤーン
