摘要:
A belt and a method for manufacturing a belt is provided. The belt includes a plurality of lengthwise-extending tension members and a jacket. The jacket substantially retains the plurality of tension members. The jacket has a first side region, a second side region, and a center region between the first and second side regions. The first and second side regions of the jacket are more fire retardant than the center region of the jacket.
