Abstract

La présente invention concerne un dispositif de soudage et de coupe pour le soudage et la coupe d'une feuille en matière plastique. Ce dispositif utilisé dans un dispositif pour l'emballage d'un empilage se trouvant sur une palette est caractérisé par le fait que le dispositif de soudage est constitué par une électrode de soudage 8 en forme de mâchoire et par un levier coudé 9 solidaire de l'électrode de sondage qui est monté oscillant sur un chariot 2 sous l'action d'un vérin 10 et par le fait que le dispositif de coupe est constitué par un couteau dentelé 12 qui est fixé sur un levier 13 monté oscillant sur le levier coudé 9. Ce dispositif permet un emballage en continu de l'empilage.The present invention relates to a welding and cutting device for welding and cutting a plastic sheet. This device used in a device for packaging a stack located on a pallet is characterized by the fact that the welding device consists of a welding electrode 8 in the form of a jaw and by an angled lever 9 integral with the 'probing electrode which is mounted oscillating on a carriage 2 under the action of a jack 10 and by the fact that the cutting device is constituted by a serrated knife 12 which is fixed on a lever 13 mounted oscillating on the angled lever 9. This device allows continuous packaging of the stack.
