Abstract

Un segment pivotant à couteau de coupe en profondeur et un ensemble de couteaux pivotants, sont accouplés par un mécanisme à levier se composant d'un culbuteur qui est monté à pivotement sur le corps de rabot et auquel le segment pivotant et l'ensemble de couteaux sont reliés chacun par une barre de commande. L'articulation reliant la barre de commande du segment pivotant au culbuteur se trouve à plus grande distance de l'articulation du culbuteur que l'articulation reliant la barre de l'ensemble de couteaux pivotants.A pivoting segment with a depth cut knife and a set of pivoting knives are coupled by a lever mechanism consisting of a rocker arm which is pivotally mounted on the planer body and to which the pivoting segment and the knife set are each connected by a control bar. The articulation connecting the control bar of the pivoting segment to the rocker arm is at a greater distance from the articulation of the rocker arm than the articulation connecting the bar to the set of pivoting knives.
