<p>Grid forming machine for making plates of electric storage cells, which comprises two pressing towers (5, 6) operatively active in succession on a continuous lead band (2) that advances with a substantially constant speed, and each equipped with a framework (5', 6') slidably mounted along the direction of forward movement of the band (2) on the support structure of the machine; with a linear actuator (13, 14) mounted on the framework (5', 6') of the tower and supporting a relative press (17, 18); and with a matrix (15, 16) fixed to the framework (5', 6') under the linear actuator (13, 14). The two presses (17, 18) of the two pressing towers (5, 6) are moved cyclically and alternatingly by the linear actuators (13, 14). Moving means (20) are foreseen acting on the pressing towers (5, 6) to move them sliding with a back -and- forth cyclical stroke, and actuation means (210) to cyclically and alternatingly control the linear actuators (13, 14) to move the presses (17, 18) from the raised position to the lowered position.</p> |
