METHOD FOR MANUFACTURING A V-RIBBED BELT

摘要

A method for manufacturing a V-ribbed belt, in which a non-crosslinked rubber sheet for forming V-ribs is produced by extruding, in an extruder, a non-crosslinked rubber composition not containing short fibres. At least the surface layer of the non-crosslinked rubber sheet on the side where the V-ribs are formed is formed from a non-crosslinked rubber composition containing a blowing agent and/or hollow particles for forming pores on the V-ribbed surface.
