Abstract
A guard intended to prevent hand-injuries against tear-bars has an elongated form (6) and extends parallel with a tear-edge and is moveable in a direction transversal to its longitudinal axis. The guard (6) has a length equal to the length of the tear-bar (2). The guard (6) is guided in a gap (5) defined between a strip-like (4) front side of the tear-bar (2) and an inwardly angled part of the wall (1) of the casing intended to accommodate, for instance, a paper-roll holder incorporating the tear-bar (2). For the purpose of limiting movement of the guard (6) between an outer active guard position and an inner inactive position, in which the tear-edge of the tear-bar (2) is exposed, there is provided along the guard (6) a rib (8) which abuts the free edge of the strip-like front side of the tear-bar in the outer position of the guard. The guard is displaced to its inner position in the gap (5) by the material web (P) when severing the paper-web against the tear-bar (2).
