Abstract
An elastomeric strip has a support frame having selected regions of longitudinally displaceable frame portions such as wire loops reinforced by degraded and non-degraded materials that are non-degradable during the frame coating operation for inhibiting longitudinal displacement of the frame portions during the frame coating operation. The degraded material breaks down when the strip is flexed to allow increased flexibility of the strip, and the non-degraded material prevents undue elongation or stretching of the strip. A method of manufacturing the strip comprises reinforcing regions of the frame portions with degradable materials, arranging the reinforced support frame in position to be coated, coating the reinforced support frame with an elastomeric material, and then degrading selective regions of the degradable reinforcing materials.
