    • In method and apparatus for making continuous strips for lead acid batteries, a strip of lead is advanced through a plurality of successive stations such that zigzag slits are formed on the strip, either in a direction parallel to the longitudinal axis or inclined to the longitudinal axis of the strip, between belt-shaped unslitted edge portions and a central unslitted portion. The strip is then stretched by application of a continuous force substantially simultaneously to the entire width of the slit portion of the strip by successively larger vertical components normal to the plane of the strip between both unslitted edge portions and the central unslitted portion. Simultaneously therewith, frictional resistance is applied to the zigzag slits so that the strip forms a substantially V-shaped cross-section vertical to the advancing direction of the strip to form the grid cells. The V-shaped strip is then leveled and flattened.
    • 在用于制造铅酸电池的连续条带的方法和装置中,通过多个连续的台阶推进一条引线,使得在条带上或者在平行于纵向轴线的方向上或者相对于纵向轴线倾斜地形成锯齿形狭缝 在带状未完成的边缘部分和中心的未完成部分之间。 然后通过在两个不整齐的边缘部分和中心的不完全部分之间连续地垂直于条带平面的垂直分量,通过连续施加基本上同时的条带的狭缝部分的整个宽度来拉伸条带。 同时,对锯齿形狭缝施加摩擦阻力,使得带条形成垂直于条带前进方向的大致V形的横截面以形成网格单元。 然后将V形条平整并变平。
