<p>An apparatus for joining plywood core strips comprises a feeding conveyor floor (1) for the wood strips to be jointed, a crowding conveyor floor (7) therefore and pressure elements (22,24), effective to press the wood strips against the feeding and crowding conveyor floors (1 and 7). Each pressure element includes a rod (22,24) having its front end (22f,24f) bent upwardly and supported by the machine frame (23, 25) through a kinematic train (22a,22b, 24a,24b) including a pneumatic cylinder (22c,24c) urging the rod (22,24) against the underlying conveyor floor (1, 7). Alignment means (26,26') including stop pawls (26') and sensors (34) controlling the actuation of the stop pawls (26') are provided to align the strips perpendicular to the feeding direction, as well as jointing material applying means (39-53).
