Abstract
An elongated extruded strip adapted to be mechanically secured to a slotted sheet-like substrate is provided by extruding an elongated thermoplastic strip having a body portion which includes a rear face having a rearwardly projecting rail and then notching out longitudinally spaced portions of the rail to provide longitudinally spaced teeth. The strip is pressed against the sheet to force the teeth through the slots and heat is applied to the portions of the teeth which project through the slots to form a head or bead on the teeth and thereby mechanically secure the strip to the substrate. The strip is preferably formed to include at least one side support and/or at least one resilient adhesive tape may be used to allow the strip to deform when pressed against the substrate to force the teeth to project further through the slots to insure a tight securement. The teeth may have an arrowhead when the sheet-like substrate is of uniform thickness.
