ABSTRACT:
A device for a roll spindle for unwinding or winding up a web material comprises a brake mechanism, a clutch between the spindle and the brake mechanism for axial connection of said parts, and means provided to perform two operations in the axial direction, namely a first operation for causing the mechanism to be moved towards or from the roll spindle in the axial direction for the engagement and disengagement, respectively, of the mechanism with and from the spindle, respectively, and a second operation causing the mechanism when connected with the spindle to be moved in the axial direction for lateral adjustment of the web material. The device is characterized by an articulated joint (15) with a link (16) between a first (17) and a second (18) hinge joint, whereby said first hinge joint is connected to said mechanism (2) and whereby said means for providing said first operation comprise means (24, 20) for displacing said second hinge joint relative to said first hinge joint and means (12, 3) provided at the same time to prevent the mechanism from significantly rotating about its center axis, whereby the mechanism is forced to move in its axial direction, while said means for performing the second operation comprise means (24, 26, 27, 20) for locking said second hinge joint (18) such that said second hinge joint during said operation remains essentially stationary, and means (12, 3) provided at the same time to rotate the mechanism about its center axis such that the articulated joint also in this case will force the mechanism to perform a movement in the axial direction.
