A support bar has a central region for a material web wound to a coreless roll and a first and a rotatable second bearing journal each projecting beyond the roll. The support bar includes a first and a second part. The first part extends throughout the roll. A first end of the first part forms the first bearing journal. A second part, formed as a rotary body that is rotatable relative to the first part has a second end that forms the second bearing journal. A second end of the first part is formed with an axial bore and a first end of the second part is latched in the axial bore within the roll. |
