ABSTRACT:
A method and device for conveying folded sheet elements, whereby a sheet element, folded to have at least two superimposed portions connected along a fold, is fed along a given path by a movable gripping head, which engages and retains by suction a first of the two portions of the sheet element, and simultaneously deforms the fold to retain the second portion in contact with the first as the sheet element is conveyed.
