重疊式網(wǎng)帶又稱人字型網(wǎng)帶左、右螺線緊密組合，用直心力骨進(jìn)行連接，A4是指一條螺線內(nèi)有4根力骨貫穿，A3的話是一條螺線內(nèi)有三根力骨貫穿。
　　The left-wound and right-wound spirals are fitted Tightly together althernately and jointed with straight Rods. A4 uses 4 rods for one spiral to joint. A3 uses 3 rods for one spiral to joint.

　　
　　Advantages
　　1.平滑表面，適合運(yùn)送小件，不穩(wěn)固之處理件。
　　Since the surface is flat and smooth ,the belts can
　　Carry small items and unstable products.
　　2.容許張力大，可運(yùn)載重物件。
　　The allowable tension is high,so that heavy load
　　Can be transported.
　　3.網(wǎng)帶抗壓強(qiáng)，可用于沖壓作業(yè)。
　　The belt strength against pressure high,so that
　　The belts can be used for processing under pressure.
　　4.適用于高溫作業(yè)。
　　The belts can be used at haigh temperature.
　　5.可用于纖維制品之洗練、洗凈工序。
　　The belt can be used for textile producs refining
　　And cleaning process.
