ABSTRACT A technique for adhering individual patches of substrate material to spaced-apart regions of a moving web layer comprises a transporting mechanism for moving the web layer and a supplying mechanism for providing a selected substrate material. An applicating mechanism deposits a selected coating of hotmelt adhesive onto the substrate material, and a regulating mechanism automatically maintains a selected cross-directional registry between the substrate material and the deposited coating of adhesive. The coated substrate is cooled, and a directing mechanism engages the coated substrate to feed it to a separating mechanism at a selected rate. The separating mechanism segments the coated substrate into individual patches. A phasing mechanism provides a selected spatial segregation between the individual patches, and an assemblying mechanism adhesively secures the segregated patches onto selected spaced regions of the moving web layer. An indexing mechanism selectively displaces the coated substrate material from the separating mechanism when the directing mechanism is disengaged from the substrate material.
