Apparatus for producing a grid for a battery plate, and method of producing the same

摘要

It is an object of the invention to provide an apparatus for producing a grid for a battery plate which can improve the life performance of a lead storage battery, and in which a lead sheet 4 is prevented from being undulated or causing vibrations in a carrying-out portion of disk cutter rolls 2 and 3, and also a method of producing such a grid. As means for attaining the object, the axis-to-axis distance L (mm) of the two disk cutter rolls 2 and 3 in which a reference circumferential face has a radius r (mm), and which are opposed to each other is in a range of 2r-0.3 mm<=L<2r. The lead sheet 4 which has been passed through between the two disk cutter rolls 2 and 3 is once transported along the peripheral face of the lower disk cutter roll 3, and the lead sheet 4 which is transported only along the peripheral face of the disk cutter roll 3 is pulled out from a position of the peripheral face in a tangential direction to be carried out.
