Beschreibung
Zusammenfassung:	A method and an apparatus are disclosed for forming expanded mesh sheet from deformable strip by the steps of concurrently slitting and preforming the strip to provide transverse bands of slit and elongated wire segments projecting alternately from opposite sides of the plane of the strip separated by transverse bands of unslit strip, slitting the strip at alternate bands to extend slit segments in a staggered relation and laterally expanding the slit and preformed strip. Concurrent slitting and preforming and subsequent slitting can be effected by a cluster of three rolls or by a linear arrangement of pairs of opposed rolls. The invention has particular utility in forming expanded mesh sheet of exact final dimensions for use as battery grids from lead or lead alloy strip.
