Abstract
The present invention provides a process and apparatus for applying a web component (42) to a moving substrate (44). The process aspect includes a delivering of the web component (42) to a rotatable applicator wheel (58). The applicator wheel has an entry surface-region (114), an exit surface-region (116), a transport surface-region (118), and an applicator wheel diameter (112). The web component (42) is contacted onto the entry surface-region (114) of the applicator wheel (58), and the applicator wheel is rotated to move the web component along a substantially circumferential, applicator path along the transport surface-region (118) of the applicator wheel. The applicator wheel (58) is oscillated about a pivot axis (102) which is spaced from the moving substrate (44) by a pivot distance (100), and the web component (42) is operatively applied from the exit surface-region (116) of the applicator wheel (58) onto the moving substrate (44) to provide a desired curved web configuration. In a particular aspect, the applicator wheel diameter (112) can be at least a selected percentage of the pivot distance (100).
