ABSTRACT:
A raw edge type endless power transmission V-belt having a first rubber layer, a second rubber layer, an adhesion rubber layer in which a tensile member is embedded in the form of a layer and which provided between said first and second rubber layer. The top and bottom surfaces of the V-belt are covered with cover fabrics. The layer of the tensile member is obtained by spirally winding a continuous cord, and a line connecting the centers of the cords laterally of the V-belt is a part by 2 to 20% of the thickness of the V-belt from the center line of the V-belt. The V-belt is manufactured by (a) winding at least one ply of first bias fabric around a cylindrical mandrel; (b) winding a first rubber layer and a first adhesion rubber layer on the bias fabric; (c) spirally winding a continuous cord, in the form of a layer, on the first adhesion rubber layer; (d) winding a second adhesion rubber layer and a second rubber layer around the layer of the continuous cord; (e) winding at least one ply of second bias fabric around the second rubber layer, to obtain a belt sleeve, the number of plies of second bias fabric being equal to the number of plies of first bias fabric; (f) heating the belt sleeve under pressure; and (g) cutting the belt sleeve obliquely so that V-belts having a trapezoid section and V-belts having an inverted-trapezoid section are obtained alternately.
