摘要

The invention relates to a blade holder for a device for dividing a material web (10) in longitudinal direction, said blade holder comprising a basic body (2) that can be secured on a cutter bar (M) of the device. The blade holder further comprises a blade carrier (3; 23), which can be moved relative to the basic body (2) and on which a circular blade (8; 22) is positioned rotating and which is connected to an adjustment drive (4; 24) for moving the circular blade (8; 22) from the idle position to an operating position where it is pushed against an associated rotating counter blade (9; 28) of the device. In addition, the blade holder is provided with an impact absorber (11) that is effective between the adjustment drive (4; 24) and the circular blade (8; 22) and has a high compliance to a force effective in press-on direction and a low compliance to a force effective counter to the press-on direction.
