ABSTRACT:
A distinctive apparatus for contouring a fibrous web includes a supplying mechanism for providing a fibrous web which defines an interconnected series of appointed article segments along a length dimension of the web. A conveying mechanism moves the web at a selected speed along an appointed machine direction. A scarfing mechanism removes predetermined quantities of fibers from selected regions of the fibrous web. The scarfing mechanism is constructed to provide each of the article segments with a selected contoured basis weight which varies at least along the length dimension of the segment in a selected correspondence with a predetermined scarfing pattern. The scarfing pattern is provided by an outer peripheral surface of the scarfing mechanism, and the pattern is configured to have a selected variation at least along a movement direction of the scarfing mechanism. A regulating mechanism controls a relative movement between the conveying mechanism and the scarfing mechanism to provide the selected correspondence and to thereby form the selected contoured basis weight on substantially each of the article segments.
