<p>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.</p> |
