A binder layer for a laminated wound dressing is brought into contact with a sheet coated with a pattern-coated adhesive sheet. As the binder layer is in contact with the pattern-coated adhesive sheet, a series of closed-loop cuts are made in the binder layer. The closed-loop cuts are made in such a way that the material enclosed by each closed loop is substantially physically separated from the remainder of the binder layer. Then the binder layer is moved away from the pattern-coated adhesive sheet, so that the binder layer and the pattern-coated adhesive sheet are no longer in contact. When the binder layer and the pattern-coated adhesive sheet are moved apart, the material enclosed in the closed-loop cuts--i.e., the cut waste fragments--are retained on the pattern-coated adhesive sheet, ensuring that the binder layer includes a series of cleared perforations.
