それ力、：あるからである。However, since conventional fiber ropes on the market are simply twisted fibers, they tend to lose their shape when gripping the rope or passing through sheep, and this deformation hinders smooth running. In addition, this type of rope easily absorbs moisture, which increases its weight, and when crossing existing electric wires, the current from the wire can leak through the moisture and into the rope, causing an unexpected accident. This is because there is a power that can lead to.

にくい構成にするにある。In order to eliminate the drawbacks of the conventional technology, the present invention provides a core made of twisted fibers and a middle layer of braided fibers provided on the outer periphery of an inner layer cable. The covering layer is characterized in that a braid of heat-shrinkable resin fibers is embedded between the heat-shrinkable resin fibers, and its purpose is to create a structure that does not lose its shape and does not easily absorb moisture. It's in the middle of the day.
本発明を図面に基いて説明する、。The present invention will be explained based on the drawings.

(A covering layer (4) is completely formed by wrapping a tape of a heat-melting resin such as polyethylene around the outer periphery of 11, and furthermore, a fiber of a heat-shrinkable resin such as polyester is wrapped around the outer periphery of the covering layer (4). are braided or twisted to form an outer covering layer (5) covering the outer periphery thereof.

る。The entire fiber rope element (61f) is constructed in this manner, and the fiber rope element (61f) is passed through a furnace and the coating layer (4) and outer coating layer (51'k) are heated at a temperature of about 150 to 300°C to form fibers. A rope (10)' is produced. This heating causes the covering layer (4) to melt and the outer covering layer (5) to shrink.

い。According to such a fiber rope (10), the inner layer rope (1) and the outer layer (5) are firmly bonded to each other through the covering layer (4), and a part of the resin of the covering layer (4) are embedded between the fibers of the outer sheath layer (5), so the inner cord (1) and the outer sheath layer (5)
), and therefore the fiber rope (10) does not lose its shape when passing through sheaves gripped from both sides.

なる。In addition, the inner layer cable (11) is covered with a resin coating layer (4), so that moisture does not penetrate into the inner layer cable [11] and only slightly penetrates into the outer coating layer (5). Therefore, it is possible to suppress an increase in weight and is advantageous in terms of electrical insulation.
なお、この発明の繊維ロープはリードローブとして使用
する場合に限るものでなく、他の用途にも使用可能であ
ることは言うまでもない。It goes without saying that the fiber rope of the present invention is not limited to being used as a lead lobe, but can also be used for other purposes.
以上説明したようにこの発明の繊維ロープは］」１ｃ記
構成全具備するので、形崩れを起しにくい、水分を含み
にくい、などの作用効果を生ずる。。As explained above, since the fiber rope of the present invention has all of the configurations described in section 1c, it produces effects such as being less likely to lose its shape and less likely to contain moisture. .
