ABSTRACT:
A method of making a power transmission belt/belt sleeve having a body with a continuous length extending around an axis, an inside, an outside spaced radially from the inside, and at least one of a) a plurality of ribs extending lengthwise and b) a plurality of cog teeth spaced at lengthwise intervals, on one of the inside and outside of the belt/belt sleeve. The method includes the steps of: forming a first belt/belt sleeve component with a compression rubber layer; applying a radial force on the first belt/belt sleeve component so as to urge the first belt/belt sleeve component against a mold surface and thereby forming the at least one of the plurality of ribs and plurality of cog teeth in the first belt/belt sleeve component; forming a second belt/belt sleeve component having at least a part of a cushion rubber layer and a load carrying member; and after forming the at least one of the plurality of ribs and plurality of cog teeth on the first belt/belt sleeve component, joining the first and second belt/belt sleeve components to each other.
