(54)	Assembly and method for realizing in continuous covering jackets of different dimensions starting from a film wrapped up in a coil

(57) Assembly (10) for realizing in continuous covering jackets (11) of book elements (12) of different dimensions starting from a film (13) wrapped up in a coil (14), said assembly (10) comprising:
- cutting means (15, 25, 35) of said film (13) unrolling from said coil (14) for realizing pieces (16) of said film (13);
- a first folding device (17, 27, 37, 47) of a first end (18) of said pieces (16) of said film (13);
- a second folding device (19, 29, 39, 49, 59) of a second end (20) of said pieces (16) of said film (13); and
- a control and command unit (21) of said cutting means (15) and/or said first (17, 27, 37, 47) and second (19, 29, 39, 49, 59) folding means according to the characteristic dimensions (A, B, C) of said book elements (12).
- a longitudinal welder (101) suitable for both superiorly and inferiorly closing folded pockets (18) and (20) and for regulating the height of the cover itself by trimming the parts in excess.
