없음 An elastomeric strip (16) of substantially U-shaped cross-section is disclosed which is adapted to be mounted on a flange (14) having longitudinally-spaced curved sections. The elastomeric strip (16) includes a support frame (22) having longitudinally displaceable frame portions that are reinforced with longitudinally extending degradable reinforcing material. The reinforced support frame (22) is advanced through an extrusion die where a coating of an elastomeric material is extruded on the support frame to form an elastomeric strip without degrading the degradable material. Longitudinally-spaced regions of the degradable reinforcing material corresponding to the longitudinally-spaced curved sections of the flange are then degraded, allowing the elastomeric strip to more faithfully follow the curved sections of the flange when the strip is mounted thereon.
