Abstract
An endless fabric belt subjected to a substantial running tension. The belt has an endless woven fabric formed from a plurality of MD (machine direction) ultra high molecular weight polymer strands approaching zero creep at high tensile loads. A plurality of CMD (cross machine direction) strands are interwoven with the MD strands. The plurality of MD strands have first and second ends spliced to one another to form an endless belt, the splices forming a significant linear MD overlap of about 30 cm with each other.
Claims21
An endless fabric belt subjected to substantial running tension, said belt comprising:
- an endless woven fabric formed from at least one machine direction strand approaching zero creep, at high tensile loads;
- at least one cross machine direction strands interwoven with said machine direction strand;
- said machine direction strand having first and second ends spliced to one another to form an endless belt, said splices forming a significant linear machine direction overlap with each other.
A method of forming an endless fabric belt subjected to substantial running tension, said method comprising the steps of:
- interweaving at least one machine direction strand with at least one cross machine direction strand to form a fabric, at least said machine direction strand being formed from material approaching zero creep at high tensile loads and having first and second ends;
- splicing said first and second ends of said machine direction strand to one another with a significant linear machine direction overlap to form an endless belt.
