A method for applying pressure sensitive adhesive (PSA) directly to one or both surfaces of carpet underlayment pads in which a liquid PSA polymer composition is first applied as a layer to a release substrate. The polymer layer is dried, forming a dried PSA film on the release substrate. The dried PSA film is then laminated to one or both surfaces of a carpet underlayment pad. Alternately, the film can be encased in a second substrate for storage and future application to a carpet underlayment pad.

Method for application of pressure sensitive adhesive to porous carpet

This invention relates to an improvement in a disposable absorbent article such as a sanitary napkin, etc. having a liquid permeable cover sheet or cover sheet, optionally a distribution or transfer layer, an absorbent core and a liquid-impermeable backsheet. The improvement in the disposable absorbent article resides in an improved bond for generally continuous contact between the cover sheet and the transfer layer or absorbent core. Adhesion is effected by applying an adhesive binder to the top sheet with a print roller.
