METHOD AND APPARATUS FOR MAKING A CLEANING SHEET

A method of applying an additive (4) to selected regions (56) of a web (4) includes the steps of applying the additive to the raised regions (26) of a patterned roll (10) having an outer surface comprising raised regions and recessed regions (39), providing a flat roll (12) having a smooth outer surface arranged in rotatable contact with the patterned roll, and conveying the web of material between the patterned roll and the flat roll, thereby to transfer the additive to selected regions of the web. An apparatus for selectively applying an additive to a web is also described.
