Beschreibung
Zusammenfassung:	A synthetic resin resiliently flexible separable fastener strip adapted for attachment to a substrate, is thermoplastically extruded in continuous strip form and provided with a base surface to which is applied during extrusion an adhesive in fluent state, with the extruded strip and adhesive carried thereby being then concurrently cured so that the fastener as formed and the adhesive in a dormant state on the strip can be rolled into a storage roll. The material of the fastener strip and the material of the adhesive are selected to permit the adhesive on the strip to be reactivated when the strip is to be adhesively bonded to a substrate, without deformably affecting the fastener strip. By extruding the strip without base webs, a plurality such as at least four, separate complementary strips can be extruded from a single die for efficiently joining sets of the profile strips into separable fastener assemblies immediately after concurrent curing of the extruded strips and the reactivatable adhesive.
