ABSTRACT:
Forming machine for metal strips, in particular for the manufacture of plates for electric accumulators, comprising moving means (2, 3) designed to convey a continuous strip (10) through an incision zone (8) associated with forming means (7) provided with a plurality of teeth (9) operationally actuated by actuator means (11) so as to make incisions in the strip (10) so as to form a continuous mesh (12). The actuator means (11) move the forming means (7) in accordance with a law of motion having a component oriented in the direction of feeding (A) of the strip (10) and a component oriented in a direction (B) substantially perpendicular to the direction of feeding (A) of the strip (10). The first component allows the teeth (9) to advance substantially in synchronism with the strip (10), while the second component allows the teeth (9) to make incisions in and expand the strip (10) during an incision step of the machine (1). For this purpose, the strip is fed continuously by the moving means (2, 3).
