    Abstract: The invention relates to a method or apparatus (10) for crimping a sheet (70) of material The apparatus comprises a transport device to transport the sheet of material along a transport direction (1), and a set of crimping rollers (11, 21). The set comprises a first (11) and a second (21) main crimping roller, defining a first (18) and a second (28) rotational axis and being faced one in front of the other, the first roller including a first plurality of ridges (17) across a portion of its width (16), and the second roller having a second plurality of ridges (27) across a portion of its width; and a pre-crimping roller facing the first roller and having a third plurality of ridges across a portion of its width, the pre-crimping roller having a diameter smaller than a diameter of the first and second main roller.

    Abstract: The invention relates to an apparatus for crimping a sheet of material, the apparatus comprising a first and second facing crimping roller defining a first and second rotation axis, respectively, the first roller including:



    a first plurality of circumferential ridges, each ridge defining a ridge amplitude;
    wherein each of said first plurality of ridges is interrupted along its circumferential extension forming an interruption gap where for a given interruption angle an amplitude of the ridge differs from the ridge amplitude in the remaining circumferential extension of the ridge;
    wherein said plurality of interruption gaps forms an interruption band defining a direction of extension, said direction of extension being angled with respect to a direction defined by the first rotation axis of an angle comprised between about 2° to about 25°.




    The invention also relates to a method for crimping a sheet of material as well as a crimped sheet of material and a rod made of a crimped sheet.

    Abstract: The apparatus for shaping substantially flat continuous material comprises a shaping device (500) for gathering substantially flat continuous material transverse to a longitudinal direction of the continuous material to form a gathered continuous material. The apparatus further comprises a cooling device (75) for cooling the gathered continuous material. The shaping device and the cooling device are combined such as to immediately cool the gathered continuous material.
