    摘要： An embossing and lamination assembly comprising two pairs of steel/rubber rolls, between which respectively a first paper ply (11A) and a second paper ply (11B) are returned, wherein an upper steel embossing roll (21) is coupled with an upper embossing rubber counter-roll (22) and a lower steel embossing roll (31) is coupled with a lower rubber embossing counter-roll (32), and also comprising a glue delivery assembly (40), in contact on a side of the upper steel embossing roll (21), and a coupling roll (13), in contact with the opposite side of the upper steel embossing roll (21), wherein said upper steel embossing roll (21) and/or said lower steel embossing roll (31) are equipped with heating means (50) for heating the surface of the upper steel roll (21) and/or the lower steel roll (31), the upper (22) and/or lower (32) rubber embossing rolls are mounted on a movable arm (24, 34), and return rolls (12') are arranged around the upper rubber roll (22) and/or around the lower rubber roll (32) to guarantee a tangential passage of paper between the two coupled steel/rubber embossing rolls (21, 31; 22, 32) without wrapping the respective rubber embossing roll (22, 32). A relative embossing and lamination method is also part of the invention.

    摘要： An unwinder (1) for unwinding reels (21, 22) of paper is described, which comprises:
    - a supporting structure (3) that is partially closed and defining an internal space suitable for unwinding at least one reel (21, 22); the supporting structure (3) comprises:
    - a first lateral support (31);
    - a second lateral support (32) spaced from the first support (31);
    - a crosspiece (4) interposed above between the first (31) and the second support (32) defining with said first support (31) and second support (32) the partially closed structure;

    the unwinder (1) further comprises:
    - a first axial unwinding system (5) placed at the first support (31) and configured to axially unwind a first reel (21);
    - a second axial unwinding system (6) placed at the second support (32) and configured to unwind a second reel (22);
    - a joining device (40) placed at the crosspiece (4) and configured to make a joint between a first ply (210) belonging to the first reel (21) and a second ply (220) belonging to the second reel (22) to perform a reel exchange;

    the second unwinding system (6) is configured to load the second reel (22) from a loading zone (1) after the first reel (21) being unwound on the first unwinding system (5) reaches a first predetermined diameter;
    the joining device (40) being configured to make the joint between the first reel (21) and the second reel (22) when the first reel (21) reaches a second predetermined diameter smaller than the first predetermined diameter;
    the second unwinding system (6) is configured to unwind the second reel (22) after the joint has been made, the first unwinding system (5) is configured to interrupt the unwinding of the first reel (21) after the second unwinding system (6) has started unwinding the second reel (22).
    A plant (100), at least partly automatic, comprising such an unwinder (1) and a process for unwinding reels (21, 22) by means of such a plant (100) are further described.
