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, either the upstream flow of material or the downstream speed of the web (reel speed) are adjusted to obtain the desired basis weight of the web at the reel.
