Abstract

L'invention porte sur une unité de distribution d'un composant apte à couper de façon sûre un ruban de protection et assurer ainsi la distribution fiable d'un composant électronique. Des surfaces de guidage inclinées (64) sont respectivement formées sur des côtés droit et gauche d'une partie de guidage (283) placée sur une unité de traitement de ruban (28) dans le but de guider les extrémités de rubans de protection droit et gauche coupés (C1, C2) tout en les repoussant vers le haut. Des découpes (gradins) à deux étages inférieures (284, 285) et supérieures (286, 287), ménagées par découpe de coins à angles droits, sont formées dans la direction de cheminement (vers l'avant) d'un ruban de logement (CX) dans les coins droit et gauche sous la partie de guidage (283). Une partie de poussée de ruban (288) en saillie vers le bas est formée entre les découpes inférieures droite et gauche (284, 285).
