Abstract
In the manufacture of stretchable webs such as creped tissue, nonwovens, and the like, in which the web is formed and thereafter wound onto a reel, basis weight control of the web on the reel is accomplished by measuring the speed and basis weight of the web prior to winding the web onto the reel and calculating the basis weight of the web on the reel. In response to this calculated value, the downstream speed of the web (reel speed) is adjusted to obtain the desired basis weight of the web at the reel.
