An edge trimmer for an uncured elastomer strip being conveyed in the longitudinal direction of the strip is disclosed. In the uncured elastomer strip, cords laid parallel with each other along the longitudinal direction of the strip, are embedded. The edge trimmer comprises a cutter head comprising a blade for trimming an edge portion of the uncured elastomer strip. The cutter head is freely movable in the transverse direction of the uncured elastomer strip being conveyed. The blade has a pair of v-shaped cutting edges opening towards the upper stream of the conveyed direction of the uncured elastomer strip. Preferably, the thickness of the blade is 1.0 to 2.0 mm, the opening angle of the V-shaped cutting edges is 30 to 70 degrees, an angle of each of the cutting edges is 35 to 65 degrees, and the cutting edges are formed on the thickness center plane of the blade.
