Process for removing peripheral portions such as bead regions of a glass sheet including a step of pushing the glass sheet in the peripheral portion using a pushing mechanism such as a pushing bar, and corresponding apparatus. As a result of the use of the pushing mechanism, the engagement completion time for suction cups, if used, are reduced significantly. A process without using suction cups is enabled with enhanced yield. The increased process stability and enlarged process window are particularly advantageous for processing glass sheets having high flexibility. L'invention porte sur un procédé pour retirer des parties périphériques, telles que des régions de bordure d'une feuille de verre, lequel procédé comprend une étape consistant à pousser la feuille de verre dans la partie périphérique à l'aide d'un mécanisme de poussée, tel qu'une barre de poussée, et sur un appareil correspondant. En résultat de l'utilisation du mécanisme de poussée, le temps d'achèvement de prise pour des ventouses, si celles-ci sont utilisées, est réduit de façon significative. Un procédé sans l'utilisation de ventouse est permis avec un rendement de production amélioré. La stabilité de traitement accrue et la fenêtre de traitement agrandie sont particulièrement avantageuses pour traiter des feuilles de verre ayant une grande souplesse.
