Abstract
The expanded sheet metal production machine comprises a toothed
blade mobile in two mutually orthogonal directions and cooperating
with a backing blade which can retract against the action of
elastic means during the active movement of the toothed blade.
The improvements consist in the provision of a device for feeding
the sheet metal in such a manner as to obtain: a required distance
between the holes in the sheet metal, stretching limited to
intermediate zones of a metal sheet, which therefore has front and
rear end portions free of stretch, and expanded metal sheets
starting from strip.
