Machine for making grids for accumulator plates, comprising a supporting structure (7) lying on the ground and mounting die means (9) operatively acting upon a continuous lead tape that translate with a substantially constant speed along an advancement direction (A), movement means (10) for moving the die means (9) with an advancement speed component that is oriented along the advancement direction (A), and with an expansion speed component that is oriented along a direction (B) that is normal to the translation direction (A). In turn, the movement means (10) comprise a first motorised eccentric shaft (11) mechanically coupled with the die means (9) through a movement transmission unit (12). According to the invention, the movement means (10) further comprise at least one second eccentric shaft (13) rotationally driven in phase with the firs (11) eccentric shaft that is mechanically coupled with the movement transmission unit (12) for imparting a speed correcting component to the die means (9), said speed correcting component being oriented along the advancement direction (A) in opposite sense with respect thereto.
L'invention concerne une machine de fabrication de grilles continues destinées à des plaques d'accumulateur, ladite machine comprenant une structure de support (7) reposant sur le sol et portant un dispositif de poinçon (9) qui suit, de manière fonctionnelle, un cordon d'engagement continu qui transite à une vitesse de translation pratiquement constante dans un sens d'avancement (A), un dispositif de déplacement (10) permettant de déplacer le dispositif de poinçon (9) avec une composante de vitesse d'avancement orientée dans le sens d'avancement (A) et avec une composante de vitesse d'expansion orientée dans un sens (B) perpendiculaire au sens de translation (A). Le dispositif de déplacement (10) comprend un premier arbre excentrique motorisé (11) couplé mécaniquement au dispositif de poinçon (9) par une unité de transmission de mouvement (12). Selon la présente invention, le dispositif de déplacement (10) comporte au moins un second arbre excentrique (13) actionné de manière rotative en phase avec le premier arbre excentrique (11) couplé sur le plan mécanique à l'unité de transmission de mouvements (12) en vue de transmettre une composante de correction de vitesse au dispositif de poinçon (9), ladite composante de correction de vitesse étant orientée en sens opposé au sens d'avancement (A).
