A device for positioning interlayers, comprising: gripping means (2), predisposed to grip an interlayer (L) at an end zone of the interlayer (L) itself, which are mobile between a first position, at which they can grip an interlayer (L) on an upper lying plane (G1), and a second position, at which they can release the interlayer (L) onto a lower lying plane (G2); the gripping means (2) are mobile between the first and the second position in rotation about a horizontal axis of rotation (Y) and in translation along a horizontal direction of transport (X) perpendicular to the axis of rotation (Y).
