Abstract
Apparatus and a method for laminating patches to a base web accurately, and as efficiently as possible, are provided. Two webs are fed at speeds which are related as the ratio of the width of each patch to the separation distance between patches, the patch web moving more slowly. Patches are cut from the patch web and transferred to the other web while being accelerated to the higher speed.
