摘要:Web tension in web material passing through a web transport system is determined in real time using position nsors coupled to driven rollers that define a beginning and an end of tension zone. The position nsors on the rollers provide information related to the amount of strained web material that has been added and subtracted from the web material prent in the tension zone. The amount of web material added to, subtracted from and prent in the tension zone in a sample time period is then converted to an unstrained amount of web material that when combined provides an estimate for the prent amount of unstrained web material prent in the tension zone. Becau the length of the tension zone is both fixed and known, the tension in the web material is determined from the prent amount of unstrained web material in the tension zone.
