    Abstract: The present invention relates to a converting machine, i.e., a machine for winding or unwinding a strip of material on coils, particularly configured to process a delicate material.
    In particular, the invention is directed to a machine (1) for converting coils of a material into smaller coils, wherein the strip (N) is moved along a path (P), comprising a loading unit (2) of a strip (N) of material into the machine (1), an accumulation unit (3) of the strip (N) being processed, and a winding unit (4) of the strip (N) on a winding shaft (5, 5′) to form respective coils (B), said units being positioned along said path (P), characterized in that the accumulation unit (3) comprises:



    a first movable supporting structure (20) for a first series of movable rollers (21) and a second movable supporting structure (20′) for a second series of movable rollers (21′), wherein each series of movable rollers (21, 21′) comprises a plurality of rollers aligned vertically in a plane parallel to a first and second straight path stretch (Pv1, Pv2), said first and second straight path stretches (Pv1, Pv2) being connected by a third upper path stretch (Ps), to form as a whole a substantially π-shaped path stretch (P), which encloses said movable supporting structures (20, 20′) underneath, and wherein said first and second movable supporting structures (20, 20′) slide in opposite directions away from each other between a retracted position, in which the movable rollers (21, 21′) are not in contact with the strip (N), and a plurality of extended positions, in which the movable rollers (21, 21′) are in contact with the strip (N);

    a first series of fixed rollers (19) and a second series of fixed rollers (19′), facing the first and second series of movable rollers (21, 21′), respectively, but staggered vertically with respect thereto, each series of fixed rollers (19, 19′) comprising a plurality of vertically aligned rollers, respectively, on a plane parallel to said first (Pv1) and second (Pv2) stretches of path (P) and facing one side of said path stretches (Pv1, Pv2) opposite to said first and second series of movable rollers (21, 21′), i.e., on the outside of the π-shaped path stretch (P) so that said path stretches (Pv1, Pv2) are placed between said fixed rollers (19, 19′) and said movable rollers (21, 21′).

    Abstract: The present invention relates to a converting machine, i.e., a machine for winding or unwinding a strip of material on coils, particularly configured to process a delicate material.
    In particular, the invention is directed to a machine (1) for converting coils of a material into smaller coils, comprising a loading unit (2) for automatically loading a strip (N) of material into the machine (1), an accumulation unit (3) of the strip (N) being processed, and a winding unit (4) of the strip (N) on a winding shaft (5, 5′) to form respective coils (B), characterized in that the loading unit (2) comprises an accompanying system (6) for the strip (N) from the loading unit (2) to the winding unit (4), said accompanying system (6) consisting of a double chain (7), comprising a first chain (7a) and a second chain (7b) and an accompanying bar (9) driven by said first and second chains (7a, 7b), wherein the double chain (7) develops in a loop along a path (P) and wherein the accompanying bar (9) is movable along the loop-shaped path (P) and is configured to drive the strip (N) from the loading unit (2) to the winding unit (4) and then, after releasing the strip (N), to return to the starting point in the loading unit (2).

    a revolving disc (29), which supports two winding shafts (5, 5′) of coils (B);
    a feeding roller (30) of the strip (N) to a winding position;
    a movable accompanying member (31) of the strip (N) and a cutting member (32) operatively associated with said feeding roller (30),
    wherein the feeding roller (30), the movable accompanying member (31), and the cutting member (32) are placed on a carriage (33), movable horizontally between at least one forward or operating position and a retracted or resting position;
    and wherein the movable accompanying member (31) and the cutting member (32) are hinged on the axis of the feeding roller (30) and are tiltable between a non-operating position and an operating position adapted to operate the crosswise cut of the strip M.
