Abstract: A line for assembling accumulator batteries comprises movement means forming a feed path for the batteries, and a plurality of operating stations mounted along the feed path, each designed to perform at least one operation on the batteries. The movement means are prepared in such a way that they keep the batteries grouped in groups each comprising a plurality of batteries drawn near to one another along a respective main side, and can be activated to move each group in sequence through the stations. There is also an assembly method comprising a first operating step in which a plurality of batteries to be assembled are picked up, being placed side by side along the main side to form a group of batteries to be assembled. Moreover, at least some of the successive assembly operating steps are performed simultaneously on all of the batteries in the group.

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).

Abstract: A machine for positioning and leveling plates for electric accumulators, is operationally arranged downstream of a machine for separating lead grids (2), initially formed by a continuous strip (5), into pairs of plates (11). The machine in question is substantially provided with an upstream section (16), a central section (20) and a downstream section (17) associated respectively with first (18), second (21) and third (22) conveying devices. The first conveying device (18) removes the plates (11) from the separating machine (2) and transfers them, through a compression station (19) to level the plates (11), to the central section (20).

Abstract: A spreading machine has a first conveyor belt, with a high friction rest surface for carrying a grid to be covered with paste; a paste spreading chamber towards which the first conveyor belt advances, where paste is spread on an upper and a lower face of the grid; apparatus for spreading paste on the grid at the spreading chamber; a paste loading hopper which feeds the spreading chamber; a second conveyor belt moving away from the spreading chamber, having an uncompressible rest surface; a calibrator for regulating breadth of paste spread on one face of the grid; a paste recycling chamber communicating with the spreading chamber and the loading hopper to remove excess paste from the spreading chamber; and a paste pressure regulator inside the spreading chamber.
