Roller Rolling Load Characteristics
Compound through the calender roller roller slot, the thickness of compound from large to small, and gradually increasing pressure, as shown in the figure.
1) in the a,b area, compound by a slow speed in the NIP of the central part, the fastest parts on both sides. But with the rubber compound, the speed decreases.
2) when b is reached, all parts at the same rate, the pressure reaches a maximum.
3) when you reach the pitch, that is, point c, rubber speed on both sides than a NIP NIP central parts parts pressure gradually decreases, the film thickness increases.
4) until d film thickness increases, rubber roller pressure drops to zero.
Visible nip in the rubber compound of rolling load is not uniform and maximum roller spacing a little while ago.
