Abstract:
1. Grid forming machine for making plates of electric storage cells, characterised in that it comprises: a support structure; a first pressing tower and a second pressing tower mounted on said support structure, operatively active on a continuous lead band that advances with a substantially constant speed in succession through said first and second pressing tower, aligned along the direction of forward movement of said band; said first and second pressing tower respectively comprising: a first and a second matrix respectively fixed on said first and a second framework below said first and second linear actuator to define a first and a second incision area together with them; said first and second press being moved cyclically and alternatingly by said linear actuators to move between at least one raised position, in which they do not interfere with said continuous band and a lowered position in which, coupling with said first and second matrix, they cut into said band forming it in the shape of a continuous grid in said first and second incision area; moving means mounted on said support structure and acting on said pressing towers to move them in a sliding fashion together and apart from one another along said direction of forward movement with a back-and-forth cyclical stroke equipped with at least one operative section with substantially the same speed as that of forward movement of said continuous band; actuation means able to cyclically and alternatingly control said first and second linear actuator to respectively move said first and second press from said raised position to said lowered position at the operative section of the cyclical stroke of said corresponding first and second pressing tower.
