[Structure] A knitted woven fabric having elasticity in all directions, which is a main component of the present invention, is coated with a rubber-like elastic body, cut in an arbitrary direction, formed into a tubular body by lap joining, and formed by inserting a ring.

Description
【0001】 図1の斜視図に示す従来の丸型ジャバラ1は糊引き処理したカバー材料2を図2 の斜視図に示す筒型に成形した筒型成形体3に金属製リング(以下リングと言う )4を挿入して形成されている。その従来の丸型ジャバラ1のカバー材料2は、 平織り布にゴム又は樹脂糊引き処理されたものであり、そのカバー材料を織り布 の織り方向に対して斜め裁断し、筒状に接着糊、縫製加工部イ等で接合し、その 筒型成形体3中に、所定のピッチでリング4を挿入するが、リング4の外周より 筒型成形体3の内周長を小さくし、リング4を挿入した時、カバー材料2の反力 により、複数のリング4間に於いて山、谷を形成し、確実に固定されるごとくす るのが一般的製法である。尚、上記カバー材料2は筒型成形体3を形成する時、 斜め裁断する事が必須条件であり、カバー材料2の縦及び横方向に平行に裁断し た場合、リング4を挿入したとき、伸びないので山、谷の高さが浅く、挿入した リングの安定性が悪くリングが倒れやすいのはもとより、ジャバラの特徴である 大きな伸縮性が得られ難い欠点を有する。従ってカバー材料を斜め裁新して加工 する筒型成形体が必要となり、長尺の丸型ジャバラを製造するときその長さに対 して斜め裁断したカバー材料2の長さが不足の場合、斜め接合にて継ぎ足す等、 品質面はもとより加工上多大の手間を必要とする欠点を有している。A conventional round bellows 1 shown in a perspective view of FIG. 1 is a metal ring (hereinafter referred to as a ring) on a cylindrical molded body 3 obtained by molding a cover material 2 having been subjected to a paste treatment into a cylindrical shape shown in a perspective view of FIG. 4) is formed. The cover material 2 of the conventional round bellows 1 is obtained by subjecting a plain woven cloth to a rubber or resin paste treatment. The cover material is cut obliquely in the weaving direction of the woven cloth, and the adhesive paste is formed into a tubular shape. The ring 4 is inserted into the cylindrical molded body 3 at a predetermined pitch. The inner peripheral length of the cylindrical molded body 3 is made smaller than the outer periphery of the ring 4 so that the ring 4 is A general manufacturing method is to form peaks and valleys between the plurality of rings 4 by the reaction force of the cover material 2 when inserted, so that the rings 4 are securely fixed. It is an essential condition that the cover material 2 is cut obliquely when forming the cylindrical molded body 3. When the cover material 2 is cut in parallel in the vertical and horizontal directions, when the ring 4 is inserted, Since it does not stretch, the height of the peaks and valleys is shallow, the stability of the inserted ring is poor, and the ring is easy to fall down. In addition, it has the disadvantage that it is difficult to obtain the large elasticity characteristic of bellows. Therefore, it is necessary to provide a cylindrical molded body for cutting and processing the cover material obliquely, and when manufacturing a long round bellows, if the length of the cover material 2 cut obliquely to the length is insufficient. It has disadvantages that require a lot of labor in processing as well as quality, such as adding by diagonal joining.
【0002】 上記間題点を解決する為に本考案者は鋭意研究を重ね、従来方式の丸型ジャバ ラ1の主体をなすカバー材料2の問題点である斜め裁断に対して、それを必要と しない全方位伸縮性を有するメリヤス編み布にゴム状弾性体をコートして成るカ バー材料(以下全方位伸縮カバーと言う)10を主体材料とする新丸型ジャバラ 及び新角型ジャバラを開発した。その内容を以下図面に従って説明する。In order to solve the above-mentioned problems, the present inventors have conducted intensive studies, and have been required to solve the problem of the oblique cutting, which is a problem of the cover material 2 which is the main component of the conventional round Java 1. A new round bellows and a new square bellows mainly composed of a cover material (hereinafter referred to as an omnidirectional elastic cover) 10 made of a knitted knitted fabric having elasticity coated on a knitted fabric having omnidirectional elasticity did. The contents will be described below with reference to the drawings.
