Abstract:
A one-step method of forming slit and preformed sheet for production of expanded mesh sheet from a deformable strip comprising the steps of concurrently slitting and forming at least a portion of said strip contained within border portions to provide a plurality of longitudinally extending wire-like components, said components comprising elongated slit segments deformed out of the plane of the strip and alternately slit segments retained in the plane of the strip, said elongated slit segments being severed from laterally adjacent segments and said border portions and being substantially convexly shaped from the plane of the strip whereby slit segments in laterally adjacent components extend from opposite sides of the plane of the strip, and said alternately slit segments retained in the plane of the strip together define nodes extending laterally at least the width of said one or more wire-like components across the said portion of the strip.
