摘要：
A method of selectively applying pressure-sensitive adhesive to a nonwoven web and thereby forming a cleaning sheet having adhesive free peaks and adhesive containing valleys includes coating an adhesive transfer roll with adhesive, transferring a portion of the adhesive to raised regions of a female pattern forming roll, and transferring the adhesive from the raised regions of the female pattern forming roll to the web. An apparatus for selectively applying pressure-sensitive adhesive to a nonwoven web and forming a cleaning sheet is also described.
