A V-belt of preferably the variable speed type with a plurality of V-blocks attached to a flat belt type load carrying section, the blocks having an embedded or partially embedded reinforcement which surrounds and supports the load carrying section. The generally flat type load carrying section is preferably of a symmetrical construction with an overcord and undercord sandwiching a tensile member. A plurality of transversely oriented ribs or teeth are located at the radially inner and outer surfaces of the load carrying section, a rib coinciding in position with the surrounding reinforcement member of each polymer block. A method for making the V-belt by fabricating a flat load carrying section with an overcord and undercord, attaching spaced reinforcements to the flat belt and surrounding the flat belt therewith, forming polymer material around at least portions of the reinforcement and defining V driving surfaces of the belt, molding the belt while simultaneously displacing portions of the flat belt from an area between spaced reinforcements to a location adjacent the reinforcements and forming transversely oriented ribs and molding and curing the belt. |
