Patent ID: 7654946

Claim:
A machine for covering a packaging box with a glued sheet, comprising a first covering head mounted on a first column and a second covering head mounted on a second column, the first covering head having a first presser and a first folding blade, each of said first presser and said first folding blade being movable horizontally in a direction towards a box to apply a glued sheet to a corresponding first sidewall of the box, the second covering head having a second presser and a second folding blade, each of said second presser and said second folding blade being movable horizontally in a direction towards the box to apply the glued sheet to a corresponding second sidewall of the box, said first column being independently rotatable about a first vertical axis of rotation so that the first covering head, the first presser and the first folding blade are also rotatable about the first vertical axis of rotation, said second column being independently rotatable about a second vertical axis of rotation so that the second covering head, the second presser and the second folding blade are also rotatable about the second vertical axis of rotation, so that (a) in a first position, the machine can apply a glued sheet to the first sidewall and an adjacent sidewall wherein the first and adjacent sidewalls define a right angle, and (b) in a second position, the machine can apply a glued sheet to the first sidewall and an adjacent sidewall wherein the first and adjacent sidewalls define an oblique angle.
