Device for folding web material in a plant for producing layered composite articles comprising: a first guide defining a feeding plane for feeding a web material; a second guide defining a receiving plane for receiving the web material, wherein the second guide is positioned downstream of the first guide with respect to a feed direction of said web material, wherein the receiving plane is orthogonal to the feeding plane; a folder arranged between the first guide and the second guide and comprising an elongated edge extended between the first guide and the second guide and having a first end close to the first guide and a second end close to the second guide; wherein the elongated edge is extended from the first guide towards the second guide in the receiving plane and away from the feeding plane, in order to progressively move an intermediate portion of the web material away from the feeding plane and fold said web material in two as it travels from the first guide towards the second guide; wherein the folder can be oriented around an adjustment axis arranged near the second guide and lying in the receiving plane, in order to vary a position of the first end of said elongated edge with respect to the first guide so as to adjust a mutual position of opposite longitudinal edges of the web material at the second guide.
