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 member.
The method of forming a corrugated package pursuant to this invention comprises the steps of corrugating an inner sheet of material having a selected width and length into fluted corrugations while forming the sheet into a shape defining a portion of the package side wall; positioning a bottom wall member having an outer edge adjacent the corrugated inner sheet; wrapping an outer sheet of material having a width greater than the width of the inner sheet around the corrugated inner sheet so that a portion of the outer sheet projects over the outer edge of the bottom wall member and; simultaneously joining the outer sheet to the inner sheet and to said bottom wall member so that said sheets form plys of a corrugated side wall and are joined to said bottom wall member to produce a corrugated package.
