Method of measuring the windup weight of a moving stretchable material

摘要

A method of determining the windup weight of stretchable material being manufactured by a machine includes the step of measuring weight per unit area at a scanner location remote from the windup reel and compensating such weight per unit area measurement by a growth ratio which is the ratio of the product of the speed and width of the material at the measuring location divided by the speed and width of the material at the windup reel location.
