<p>An air permeable pneumatic conveyor belt made of synthetic material for conveying granular particles in particular cement, wherein the warp yarns (4), woofs (5) are weaved in such a way that each warp yarns is arranged to be backward of forward position in compare to the pivotal position of the warp yarns (4) in the layer just at the bottom or above, warp yarns (4) in each layer being asymmetrically arranged, and not being at the right angle together with the latter ones at below or above and enabling the air permeable woof (5) to be weaved as to create an acute angle against the horizontal conveying axis.</p> |
