Abstract: A pallet manufacturing machine and method for joining wooden slats (W) to elongate splines (S) includes spline clamping means (70) mounted on a frame (10). The spline clamping means (70) grip and release the elongate splines (S) so that the lateral edge portions of the splines (S) extend from the clamping means (70). The wooden slats (W) are carried along the length of the frame (10) by first and second advancing means (12-18, 50-56) with the advancing means (12-18, 50-56) adapted to force the slats (W) over and onto the extending edges of the splines (S). In this way, the edges of the splines (S) are embedded within the wooden slats (W) to form a contiguous structure. Drive means (76) are provided for displacing the first and second advancing (12-18, 50-56) means along the frame. In operation, the wooden slats (W) are arranged in a generally parallel, spaced relationship and the splines (S) are clamped in the clamping assembly (70).
