CONT

[...] l'idée du multirabot consiste à réduire l'irrégularité du débit par la multiplication des rabots [...] Le multirabot [...] d'encombrement très faible, réduit d'autre part le porte-à-faux, ce qui est avantageux dans les mauvais toits. Enfin, avec plusieurs rabots, la profondeur de coupe très réduite de chacun permet l'emploi de pousseurs hydrauliques, commandés automatiquement par l'avance du rabot, l'amplitude des déplacements étant elle-même réglée d'après la dureté de la veine.
