Abstract: A machine for forming a corrugated package from sheet material including a rotatable corrugation head having a fluted periphery and a front face; corrugating means and sealing means movable into association with the head for corrugating an inner sheet material and sealing two plys of material together, respectively; means for feeding an inner sheet having a selected length and width to the head adjacent said corrugating means and means for feeding an outer sheet having a selected length and width to the head adjacent the sealing means; means for moving a bottom wall member having a selected shape into engagement with the front face of the head and associated with the first and second sheets to form the bottom wall of the package; and means to control the operation of said machine so that the rotation of said head and the function of the above-described components are coordinated to form a corrugated side wall of the package from two sheets simultaneously with the joinder of said side wall with the bottom wall
