ASSEMBLY ARRANGEMENT FOR BLADES WITH ADJUSTABLE SETTING

摘要

The pivots (2) of the blades (1) comprise removable portions (16) located at their outer end and adjustable in height using a thread (17) or a similar means in order to adjust the distance between the head (9) of a lever (10) controlling the adjustment of the blade and the casing (4) or the collar (8) of a bearing (5); if the centring bushings (7) of the bearings (5 and 6) are worn, harmful tilting of pivots (2) will be limited by a stop for the head (9).
