    摘要: An apparatus for handling a continuous web in a continuous processing operation wherein the web incorporates therein one or more stretched elastic-type elements having retractive forces active in the cross-machine direction, and limiting shrinkage of the web in the cross-machine direction to no more than about 5%. Shrinkage in the width dimension is controlled using methods including transporting the web on a sequence of rolls having on their outer working surfaces protuberances which interact with edges of openings in the web, inhibiting lateral movement of elements defining the edges of the openings, and thereby stabilizing the web in the width dimension.
