本発明は、エラストマー物品、特tこソリッドタイヤ及

強1mを形成するのが一般的である。Conventionally, for solid tires, such as pneumatic type solid tires, unvulcanized casing claps are cut into appropriate sizes, stretched using a force cutter (for example, a guillotine cutter), and then stretched using a flat roller. /L
Calender one sheet of 1@ to a certain thickness and apply it on a former as shown in FIG.
It is common to form a 1m long tunnel.
従って、繊維コード補強層の形成工程は極めて多数の工
程を必要とし、複雑で時間がかかり非能率である。Therefore, the process of forming the fiber cord reinforcing layer requires an extremely large number of steps, and is complicated, time consuming, and inefficient.

低下させる原因となっていた。In addition, if the casing wrap is cut by hand, it is difficult to cut it to a short length, so a smooth calendar sheet is best. Since there is a large amount of residual air, if the vulcanization time is shortened, this becomes continuous porous, which reduces the durability of the tire.

ものである。The present invention has been made in view of the above-mentioned conventional problems, and is made of R-fiber cord reinforcement made of frozen crushed pieces of unvulcanized rubber fiber cord material! - The method for manufacturing such an elastomer article includes cooling an unvulcanized rubberized fiber cord material to a constant temperature using the sensible heat of liquid nitrogen and crushing it; This crushed piece is put into an open roll and formed into a sheet with a desired cross-sectional shape, and this is atomized as a fiber cord reinforcing layer, greatly simplifying the process of forming the fiber cord layer. In addition to improving calender dimensional accuracy, it also increases the durability of elastomer articles by realizing a high-density reinforcing layer with no residual air.
以下、本発明の実施例をソリ・リドタイヤについて添付
図面を参照しつつ詳細に説明する。DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail regarding solid tires with reference to the accompanying drawings.

工程上の取扱いが大変容品である。As shown in FIG. 2, the unvulcanized rubberized fiber cord material 4 is
Using the sensible heat of liquid nitrogen gas, scraps of unvulcanized casings such as nylon, polyester, and rayon used in ordinary pneumatic tires are scraped to -50% by using the sensible heat of liquid nitrogen gas.
After freezing to below ℃, crush. This crushed piece (fiber cord length: 15 to 25 days) is in a dry state, and therefore, handling in the process is a major problem.

This is placed in a vulcanizing press 7 and finished by vulcanization.
従って、繊維コード層2の形成は、上記従来の工程の内
、裁断→延伸→カレンダーリングの各工程が省略される
。Therefore, in forming the fiber cord layer 2, the steps of cutting, stretching, and calendering among the above-mentioned conventional steps are omitted.

こなる。As is clear from the above description, the present invention freeze-pulverizes an unvulcanized fiber cord material and calenders the crushed material with an open roll to form a sheet, which is used as a fiber cord reinforcing layer of an elastomer article. Since it is a TiSi2 material, it is possible to replace the many complicated steps required for forming the conventional fiber cord layer with TiSi2.
This will happen.
また、繊維コード長さが短いため平滑なカレンダーシー
トが得られるのでカレンダー寸法精度が向上し、更に、
シート密度が高いことにより、エヤー残りが殆どなく、
従って連続ポーラス等の少ない耐久性の良いエラストマ
ー物品が得らnる。In addition, since the length of the fiber cord is short, a smooth calender sheet can be obtained, which improves calender dimensional accuracy.
Due to the high sheet density, there is almost no air remaining.
Therefore, a highly durable elastomer article with few continuous porosity etc. can be obtained.
