Abstract
A product and method of manufacture for an adhesive-based system to removably stick relatively flat articles on surfaces. A cured pressure-sensitive adhesive is coated on both sides of a central flat, flexible support scrim in a zoned thickness pattern which includes sufficient, continuous thickness such that the system is well suited to the removable installation of many types of articles having rough surface textures including, but not limited to, floor coverings such as woven and double-backed carpets having backs of a relatively rough texture and unitary backed carpet having a rough latex or polymeric coating and no applied secondary scrim.
Claims17
An adhesive system adapted to removably fasten area covering articles having relatively rough surface textures to surfaces, the system comprising a flat, nonwoven flexible central support scrim layer having a smooth surface sandwiched between top and bottom coats of cured pressure-sensitive adhesive wherein at least said top coat is characterized by an application-patterned outer surface wherein variations in the thickness of adhesive occur in a continuous, regular pattern to accommodate uniform adhesion to irregular surfaces of articles to be fastened.
A method of removably installing a generally rough surfaced floor covering article comprising the steps of:
- (a) applying strips of an adhesive system, the system having a flexible flat, non-woven central support scrim layer having a relatively smooth surface sandwiched between top and bottom coats of cured pressure sensitive adhesive having a high shear strength and relatively low tensile strength at least the top coat having an application patterned outer surface, said coat being arranged in a pattern of alternate thick and thin regions along the support scrim said pattern covering the area to which the article is to be applied;
- (b) applying said article to the top coat of adhesive;
- and
- (c) applying pressure to cause the adherence of the article to the adhesive layer and the adhesive system to the substrate.
