Abstract

The mechanism (14) has a gap-forming section (20a) of a pressure element (19) and associated guide rails forming a gap (20). A roll (9) is pulled into the gap during a deceleration or catching action. A stop limits the distance by which the roll is pulled into the gap, and predefines a final position for the roll. The gap is locally provided with a fitting (33) which is designed and arranged such that the roll partially slides on a bearing material in the final position of the roll, and partially slides on a harder material of the pressure element forming remaining sliding surface.
