Zusammenfassung:A method of selectively applying pressure-sensitive adhesive to a nonwovenweb and thereby forming a cleaning sheet having adhesive free peaks and adhesivecontaining valleys includes coating an adhesive transfer roll with adhesive,transferring a portion of the adhesive to raised regions of a female pattern formingroll, separating the adhesive between the adhesive transfer roll and the femalepattern forming roll, and transferring the adhesive from the raised regionsof the female pattern forming roll to the web. An apparatus for selectively applyingpressure-sensitive adhesive to a nonwoven web and forming a cleaning sheet isalso described. Se describe un metodo para aplicar selectivamente adhesivo sensible a la presion a una tela no tejida y formar mediante esto una hoja limpiadora que tiene picos libres de adhesivo y valles que contienen adhesivo que incluye recubrir un rodillo de transferencia de adhesivo con adhesivo, transferir una porcion del adhesivo a regiones elevadas de un rodillo de formacion de patron hembra, separar el adhesivo entre el rodillo de transferencia de adhesivo y el rodillo de formacion de patron hembra y transferir el adhesivo de las regiones elevadas del rodillo de formacion de patron hembra a la tela. Tambien se describe un aparato para aplicar selectivamente adhesivo sensible a la presion a una tela no tejida y formar una hoja limpiadora.
