Abstract:
1. A method for wrapping at least a portion of an article having a substantially parallelepiped shape or a parallelepiped shape with a wrapper material, the method comprising: grabbing the wrapper material along at least one first wrapper edge of the wrapper material, proximate to a first end of the wrapper material, wherein grabbing the wrapper material includes clamping the wrapper material with at least two movable gripping units located on opposed sides of the article, each gripping unit including at least first and second wrapper grippers clamping the wrapper material; extending the wrapper material over at least part of an upper face of the article; folding the wrapper material to cover at least one first peripheral face of the article with the wrapper material, such that each one of at least two first sections of the wrapper material extends beyond a respective first lateral edge of the at least one first peripheral face and such that each one of at least one second section of the wrapper material extends beyond an upper edge of a respective one of at least one second peripheral face adjacent the at least one first peripheral face; folding each first section about the respective first lateral edge and against one of the at least one second peripheral face; securing each folded first section to the one of the at least one second peripheral face; partially releasing the wrapper material such as to change a gripping configuration thereof by disengaging the first wrapper gripper of each unit from the wrapper material while keeping the second wrapper gripper of each unit clamped on the wrapper material; folding each second section about the upper edge of the respective second peripheral face and against the respective second peripheral face; and securing each folded second section to the respective second peripheral face; wherein the wrapper material remains at least partially grabbed until at least one of the at least one second section is secured.
