摘要

METHOD FOR SELECTIVELY APPLYING STICK TO A BLADE, AND APPARATUS FOR SELECTIVELY APPLYING STICK TO A CONTINUOUS SHEET. One method of selectively applying pressure sensitive adhesive to a nonwoven web and thereby forming a wiper blade having adhesive free peaks and adhesive-containing valleys includes coating an adhesive transfer roll with adhesive, transferring a portion of the high region adhesive of a female pattern forming roller, separate the adhesive between the adhesive transfer roller and the female pattern forming roller and transfer the adhesive from the high regions of the female pattern forming roller to the web. Also disclosed is an apparatus for selectively applying pressure sensitive adhesive to a nonwoven web and forming a cleaning sheet.
