Abstract
A fastener member for being secured to the surface of a foam body during a molding process in a mold form. The fastener member includes an elongate base having upper and lower opposed faces with fixating elements positioned on the lower face of the base for being positioned within and protected by a mold cavity in a wall of the mold form against foam contamination during the molding process. First and second opposed, elongate sealing ramps positioned on the upper face of the base by respective proximal ends and diverge outwardly and upwardly at an angle oblique to the base and define respective outwardly-extending distal ends. The base is sized to fit within the mold cavity with outer surfaces of the respective first and second ramps engaging and sealingly contacting respective upper wall corners of the mold at points of contact intermediate the proximal and distal ends. A magnetically-attractable material is fixed to the base for being magnetically attracted to a magnet positioned in the mold cavity to thereby seal the cavity against the sealing ramps to prevent foam from entering the mold cavity and contaminating the fixating elements.
