COMPOUND BALANCED BALANCED BELT 13 Type No. A4, A3 The left-handed and right-handed spirals are alternately assembled and connected with straight-lined rods. A4 is a type in which one spiral is connected by four rods. A3 is a type in which one spiral is connected by three rods. The left-wound and right-wound spirals are fitted tightly together alternately and jointed with straight rods. A4 uses 4 rods for one spiral to joint. A3 uses 3 rods for one spiral to joint. Feature Advantages ●conveying of small parts and unstable products is possible because the surface is smooth. Since the surface is flat and smooth, the belts can carry small items and unstable products. ●allowable tension is large and heavy load conveying is possible. The allowable tension is high, so that heavy load can be transported. ●With large surface pressure of belt, it can be used for press process. The belt strength against pressure is high, so that the belts can be used for processing under pressure. ●It can be used for the refinement and cleaning process of textile products. The belts can be used for textile products refining and cleaning process. ●It can be used even at high temperature. The belts can be used at high temperature.
