wire drawing machinery
Italy-based Tecno Impianti Srl is specialised in the supply
of wire drawing and cold rolling lines for the construction
industry. The smooth or ribbed wire which is taken-up on
the spoolers installed at the end of the lines is used in the
production of welded mesh and lattice girders.
Standard lines are composed of vertical un-coiler with two
tilting arms for permitting the welding operation between
the coils’ ends without stopping the line, mechanical descaler,
lubricant dispenser, vertical or horizontal bullblock and vertical
or horizontal spooler. The machines are equipped with
variable-speed drives and AC motors. The use of rolling/
profiling cassettes or turk-heads, also permit higher working
speeds than drawing dies. Bullblocks can also be equipped
with a single-pass or double-pass capstan but lines with three
or four passes can also be supplied.
The wire can be taken-up on fixed reels if the wire goes
directly to the production department or on collapsible reels
in case it goes to the stock or it is sold, under form of bound
coils. Vertical spoolers can also be supplied with a double reel
configuration, for permitting the reduction of down-times
needed for the reel change.
