An applicator wheel 40 and guide system are provided in order to accurately align and position web material 34, either as discrete lengths 12 or as a continuous strip, to articles or a continuous web. Specifically, the guide system includes a lateral edge guide disc 124 rotatable with the applicator wheel 40 which exhibits an edge guide surface at a first point along the periphery of the wheel applicator 40 to precisely laterally align the web material 34 and which moves radially inward from the surface of the applicator wheel 40 at an application point so as not to obstruct the application of the web material 34 to the articles or continuous web moved at a constant rate thereby. Moreover, the guide system includes the provision of an air bar 66 for forming a loop in the supplied strip of web material 34 prior to handling by the wheel applicator 40. The air bar eliminates roller inertia and guarantees consistent lengths of discrete lengths of web material 34 to be applied to articles or a web when used on a wobbler arm. The edge guide and the air bar 66 increase the accuracy with which web material 34 can be successfully applied to articles or a web with regard to lateral and length alignment, respectively. <IMAGE> |
