The invention relates to a device (1 - 4) for producing a rotor blade belt (6) for a rotor blade of a wind turbine, comprising a mold (11 - 14) which has a depression (16 - 19) that has the shape of a cavity in the cross-section, wherein material (7, 8) for a rotor blade belt (6) can be inserted or is inserted into the depression, and comprising a flat mold cover (21) which seals the depression (16 - 19). The depression (16 - 19) has lateral walls (23), an opening which is delimited by the lateral walls (23), and a base surface (22) between the lateral walls (23). The invention further relates to a method for producing a rotor blade belt (6) for a rotor blade of a wind turbine and to a rotor blade belt (6) which is produced or can be produced according to the method. According to the invention, fiber material (7) and/or fiber-reinforced material for a rotor blade belt is inserted into a cavity-like depression (16 - 19) of a mold (11 - 14) of a device (1 - 4) according to the invention such that the height of the material (7, 8) terminates flush with the lateral walls (23) of the depression (16 - 19); the depression (16 - 19) is sealed by the flat mold cover (21); the material (7, 8) is jointed into the rotor blade belt (6); and the rotor blade belt (6) is subsequently removed from the mold (11 - 14).
