Abstract
A profile strip has a closure element, made of a first material, which contains a base surface, and lateral webs or flanges extending from the base surface on each side of the closure element. An adhesive layer, made of a second material, different than the first material, is attached to the lateral webs, but not to the base surface, by co-extrusion of the adhesive layer with the lateral webs. The adhesive layer is subdivided into adhesive ribs, with each pair of the two adjacent ribs separated from each other by an adhesive-free area. Sub-dividing the adhesive layer into ribs separated by an adhesive-free area substantially eliminates the deformation of the lateral webs when they--and the adhesive ribs--are cooled after the coextrusion.
