Abstract

Grid forming machine for making plates of electric storage cells, which comprises two pressing towers operatively active in succession on a continuous lead band that advances with a substantially constant speed, and each equipped with a framework slidably mounted along the direction of forward movement of the band on the support structure of the machine; with a linear actuator mounted on the framework of the tower and supporting a relative press; and with a matrix fixed to the framework under the linear actuator. The two presses of the two pressing towers are moved cyclically and alternatingly by the linear actuators to move between a raised position and a lowered position, in which they cut the band forming it in the shape of a continuous grid. Moving means are foreseen acting on the pressing towers to move them sliding 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 the continuous band, and actuation means to cyclically and alternatingly control the two linear actuators to move the presses from the raised position to the lowered position at the operative section of the cyclical stroke of the corresponding pressing towers.
