Control system for unwind machine |
摘要 |
An unwind machine has three tension free loops between the paper roll that is unwinding and the utilization device that must be fed paper at a rate that varies widely. One loop is conventionally controlled, and the other loops act in sequence to accommodate progressively larger ranges of web speed at the utilization device while maintaining rotational speed changes at the paper roll within reasonable limits.
