Winding-up device provided with a radiation source for positioning winding cores

Longitudinally cutting device (11, 12, 13, 14) for installation in a winding device (1) in which the longitudinally cutting device (11, 12, 13, 14) cuts the sheet-shaped material (4) into different strips

• and that comprises at least one blade (14),
• and that can be displaced along a rail (12),
• and that can be inserted into the winding device (1) preferably transverse (z) to the transport direction (x) of the sheet-shaped material (4),
• whereby the position of the blade (14) can be adjusted by displacing it in the direction transverse (z) to the transport direction (x) of the sheet-shaped material
• characterized by a source of light (16) whose position can be also adjusted in the direction transverse (z) to the transport direction (x) of the sheet-shaped material by displacing the blade (14).

Process for winding up sheet-shaped material (4),

• in which the sheet-shaped material (4) is cut by longitudinally cutting devices (11, 12, 13, 14) into different strips and is wound up on each of the winding sleeves (7a, 7b) arranged on the strips and
• in which winding sleeves (7a, 7b) are arranged on at least one winding sleeve support (20) in such a manner that each strip is wound up on a winding sleeve (7a, 7b) intended for it and
• in which sources of light (16) are arranged in such a manner that they can illuminate the cutting positions of the sheet-shaped material (4) and/or the longitudinally cutting devices (11, 12, 13, 14) and at least one winding sleeve support (20)
• characterized in that the position of the sources of light (16) and that of the longitudinally cutting devices (11, 12, 13, 14) can be jointly displaced in the direction transverse (z) to the transport direction (x) of the sheet-shaped material (4).
