ABSTRACT OF THE DISCLOSURE An applicator wheel and guide system are provided in order to accurately align and position web material, either as discrete lengths or as a continuous strip, to articles or a continuous web. Specifically, the guide system includes a lateral edge guide disc rotatable with the applicator wheel which exhibits an edge guide surface at a first point along the periphery of the wheel applicator to precisely laterally align the web material and which moves radially inward from the surface of the applicator wheel at an application point so as not to obstruct the application of the web material to the articles or continuous web moved at a constant rate thereby. Moreover, the guide system includes the provision of an air bar for forming a loop in the supplied strip of web material prior to handling by the wheel applicator. The air bar eliminates roller inertia and guarantees consistent lengths of discrete lengths of web material to be applied to articles or a web when used on a wobbler arm. The edge guide and the air bar increase the accuracy with which web material can be successfully applied to articles or a web with regard to lateral and length alignment, respectively.
