Abstract: When lead plates (10) for industrial batteries are jacketed the lead plate (10) is surrounded with a first layer (12) of fiber nonwoven, with a second layer (24) of fiber nonwoven, with a layer (28) of punched or perforated plastic film and with a sleeve (30) of separator material. To simplify the jacketing, the second layer (24) of nonwoven and the layer (28) of plastic film are folded jointly around the lengthwise edges (20, 22) of the lead plate (10) and immediately after the first layer (12) of nonwoven has been folded around the lead plate (10). To do this, the lead plate (10) which has been jacketed in the first layer (12) of nonwoven and the second layer (24) and the layer (28) of plastic film are moved jointly into a folding station (C). In the folding station (C) the layer (28) of plastic film for purposes of securing the two nonwoven layers (12) and (24) which have been placed around the lead plates (10) are closed into a sleeve by joining their lengthwise edges to one another.
