ABSTRACT:
Apparatus and method for feeding a web having two portions in a path of travel. The apparatus comprises a first module including a device for feeding the two web portions in side-by-side relationship and a second module located downstream in the path of travel from the first module where the second module includes a device for feeding the two web portions in upper-lower relationship. Accordingly, the two web portions each form a loop between the first module and the second module so as to reorient from side-by-side to upper-lower relationship. The apparatus further comprises a controller operatively connected to the first module feed a device and the second module feed a device for setting the feed speed of the first module feed a device corresponding to the feed speed of the second module feed device. The method includes the steps of: (a) determining the feed speed of the second module; and (b) setting the feed speed of the first module to a corresponding value for a given feed speed of the second module.
