Abstract

L'invention concerne les appareils destructeurs de documents du type dont l'organe de coupe 10 comprend deux arbres parallèles il tournant en sens inverses et dont chacun porte un empilage de lames annulaires 17' et de rondelles intercalaires d'espacement 18, les lames des deux arbres étant mutuellement engrenées. Certaines de ces lames sont pourvues d'au moins une griffe G faisant saillie radiale à leur périphérie, qui peut être circulaire mais excentrée ou bien polygonale, auquel cas chaque griffe est disposée dans le prolongement de la moindre dimension radiale de la lame. Des couples de lames adjacentes, respectivement portées par les deux arbres tournant en synchronisme, peuvent être pourvues de griffes symétriquement disposées. L'invention facilite la destruction de feuilles froissées ou chiffonnées en boule.
