The upper-blade holder comprises an upper-blade journalling (12) supported from both sides of the blade (50), which said journalling can be replaced without tools. The upper-blade holder further comprises a protective cover (51) of the upper blade (50), which said cover can be replaced without tools. This blade cover (51), together with the frame (1) of the upper-blade holder, encloses the upper blade (50) and the lowering arms (5,6) for the upper-blade journalling (12). Moreover, the upper-blade journalling (12) comprises an actuator, by means of which the blade (50) is displaced to the cutting position (A).</p> |
