ABSTRACT:
An emergency stretch belt and a process for making same are described. This belt is capable of an elongation of at least 11/2 percent after vulcanization and comprises a body portion of flexible elastomeric material having a load carrying section embedded in the body portion including an undulating strength member.
The belt of this invention is made by assembling a belt structure upon a forming mandrel, placing the belt structure around a curing mandrel having a smaller diameter than the diameter of the forming mandrel, and vulcanizing the belt structure to form a completed belt structure.
