Abstract
A plurality of abrasive sleeves (3) surround a wire rope (2) and are spaced at predetermined intervals longitudinally of the wire rope. An elastic material (4) of rubber such as natural rubber is formed between the abrasive sleeves in such a manner as to surround the wire rope. A rubber/metal bonding agent (7) such as chlorinated rubber type bonding agent is used to effect vulcanization bonding between the opposite end surfaces of each abrasive sleeve and the elastic material and between the wire rope and the elastic material. The ends (19) of the wire rope are connected together by a combination of end connecting members (5, 6a) provided with male threads (17, 17a) and fixed to the ends of the wire rope and on internally threaded connecting sleeve (30), whereby a closed loop is formed.
Claims12
A wire saw comprising:
- a wire rope;
- a plurality of abrasive sleeves, each having opposite end surfaces and an outer peripheral surface and an inner peripheral surface, said outer peripheral surface having abrasive particles exposed thereon, said abrasive sleeves surrounding said wire rope and spaced at predetermined intervals longitudinally of said wire rope;
- an elastic material of rubber surrounding said wire rope between said abrasive sleeves and between said inner peripheral surface of each of said abrasive sleeves and said wire rope;
- and
- a rubber/metal bonding agent which effects vulcanization bonding between the opposite end surfaces of each of said abrasive sleeves and said elastic material, between said wire rope and said elastic material, between said inner peripheral surface of each of said abrasive sleeves and said elastic material, and between said wire rope and the portion of said elastic material surrounded by said inner peripheral surface.
A wire saw comprising:
- a wire rope;
- a plurality of abrasive sleeves, each having opposite end surfaces and an outer peripheral surface and an inner peripheral surface, said outer peripheral surface having abrasive particles exposed thereon, said abrasive sleeves surrounding said wire rope and spaced at predetermined intervals longitudinally of said wire rope;
- an elastic material of rubber surrounding said wire rope between said abrasive sleeves;
- a rubber/metal bonding agent which effects vulcanization bonding between the opposite end surfaces of each of said abrasive sleeves and said elastic material, and between said wire rope and said elastic material;
- and
- end connecting means for forming said wire saw in a closed loop, said end connecting means including:
- threaded end connecting members fixed to the opposite ends of said wire rope, each of said threaded end connecting members being formed with a male thread;
- and
- a threaded connecting sleeve for connecting two of said threaded end connecting members, said threaded connecting sleeve being formed with a female thread for engagement with said male thread of two of said threaded end connecting members, said female thread being a single-directional thread.
A wire saw comprising:
- a wire rope;
- a plurality of abrasive sleeves surrounding said wire rope at predetermined intervals along said wire rope;
- an elastic material surrounding said wire rope substantially along the length of said wire rope, said elastic material being between said wire rope and said abrasive sleeves;
- and
- a bonding agent on said wire rope and said abrasive sleeves, said bonding agent effecting vulcanization bonding between said abrasive sleeves and said elastic material, and between said wire rope and said elastic material.
