The invention relates to a device for welding together the ends of tubular plastic containers, notably tubes. Said device comprises a holding device which keeps the container stationary such that its opening points upwards, as well as means for heating an annular peripheral area of the container near its opening so that the opening can subsequently be welded along an elongated seam running perpendicular to the length of the container. A plurality of diode lasers (14) is positioned on a support (12) in a virtually circular manner in such a way that their beams strike the inner or outer wall of the container (10) either directly or via an optical deflection element.
L'invention concerne un dispositif pour souder l'extrémité de contenants tubulaires en matière plastique, notamment de tubes. Ce dispositif présente un système de retenue, qui maintient le contenant dans une position fixe, l'ouverture dudit contenant étant dirigée vers le haut, ainsi que des moyens pour chauffer une zone périphérique annulaire du contenant à proximité de l'ouverture afin de réaliser ensuite un soudage le long d'un joint allongé s'étendant transversalement à la longueur du contenant. Une pluralité de diodes laser (14) est placée au niveau d'un support (12), pratiquement de façon circulaire, de sorte que leurs faisceaux frappent la paroi interne ou externe du contenant (10), directement ou par l'intermédiaire d'un élément optique de déviation.
