Abstract
An apparatus and a method for inflating an inflatable web in which, in one embodiment, the inflatable web is conveyed along a path of travel with an inflation element positioned between unsealed edges of the web and proximate the inflation ports of the web's inflatable chambers, and a tracking sensor is used to detect the transverse position of the web with respect to the inflation element. A web tracking system is employed to continually adjust the transverse position of the web to maintain it within a predetermined range with respect to the inflation element. In this manner, the consistency of inflation of the inflatable chambers is improved.
