Abstract
In a friction drive belt (B), a belt body (10) made of a rubber composition is wrapped around pulleys to transmit power. A powder layer (16) is combined and integrated with a pulley contact-side surface of the belt body (10) located on a side that is to contact the pulleys, so that the powder layer (16) covers the pulley contact-side surface.

17. A friction drive belt, comprising:
-
a belt body that is made of a rubber composition and is wrapped around pulleys to transmit power, wherein the friction drive belt is manufactured by providing a layer of powder by spraying, in advance, powder to a molding surface of a belt forming mold which is configured to form a pulley contact-side portion, pressing against the molding surface an uncrosslinked rubber composition configured to form the belt, and thus crosslinking the uncrosslinked rubber composition.

28. A method for manufacturing a friction drive belt, comprising:
-
pressing an uncrosslinked rubber composition configured to form the belt, against a molding surface of a belt forming mold which is configured to form a pulley contact-side portion, and thus crosslinking the uncrosslinked rubber composition; and before pressing against the molding surface of the belt forming mold the uncrosslinked rubber composition configured to form the belt, providing a layer of powder by spraying, in advance, powder to the molding surface of the belt forming mold. - View Dependent Claims (29, 30, 31)
