GRATEX BELT 11 TYPE No. F2, A2 Left winding and right winding spirals are interconnected with straightened rods. A2 with rod pitch less than twice spiral pitch. F2 with rod pitch more than twice. The left-wound and right-wound spirals are alternately arranged and jointed with the straight rods. If the rod pitch is less than two-fold spiral pitch, the belts are called A2. If the rod pitch is equal to or greater than two-fold spiral pitch, the belts are called F2. Feature Advantages ●conveying of unstable product is possible because surface is smooth. The surface is flat, so that unstable items can be carried. ●allowable tension is large and heavy load conveying is possible. The allowable tension is high, so that heavy load can be carried. ●It can be used for high temperature. The belts can be used at high temperature. ●aperture can be made small, so small conveying is possible. The belts can have tight mesh, they can carry small materials.
