Strip decoiling and strip coiling

> 01

The decoilers for vertical decoiling are
often equipped with a precision coil
mandrel with central adjustable strip
tension, recommended when using
thin and narrow strips to protect the
strip edges.
SOPREM’s smallest decoilers are
suitable for a max. coil weight of 30
kg and 100 kg respectively. Several
thousands of these are used all over
the World, especially in the watch-
making and small electronic compo-
nents industries. We also offer a wide
range of options, e.g. different loop
controls, paper decoiling and rewind-
ing as well as double decoilers.

Strip straightening and part levelling

> 01

More and more often the punching in-
dustry uses a motorized strip straight-
ener in front of the press. Straighten-
ing conserves tools thereby producing
more accurate components. As the
strip is fed over the loop into the roller
feed without any pulling force, higher
production rates can be achieved.
Part levellers can be used with lasers.
The parts cut out by laser must often
be straightened afterwards. SOPREM
has acquired the Schubert-straight-
ening-program and offers a wide
product range.
Straightening tests:
Tests are carried out prior to any ma-
chine purchase, we determine the
correct straightener size and the most
suitable straightening geometry.

Strip decoiling, straightening and feeding

> 01 > 02

If there is insufficient space in your
workshop, you will find the solution
in the compact design of SOPREM
equipment. We combine the decoiler
with the straightener to a strip feeding
system. Optionally the straightener
can be equipped with an integrated
feed. This compact design allows you
to easily incorporate the equipment in
a cut-to-length line or in a strip feed-
ing system. The loop between the
straighter and the press is not neces-
sary in this system.

The compact designs of SOPREM
equipment are becoming more and
more popular, as they allow optimum
use of production space.

Strip welding and strip accumulating

> 01

Strip feeding lines and strip accumu-
lators are necessary because of the
high production requirements in com-
pound pipe production. Non-stop pro-
duction places the highest demands
on the reliability of the strip accumulator
and the welding unit. If the first strip
end welding fails, the strip accumulator
needs to have sufficient material for
the second weld.
SOPREM builds this equipment to
highest quality standards meeting all
the requirements of a 24 hour, 7 days
a week non-stop production.

Wire decoiling, straightening and cut-to-length

> 01

Modern production companies au-
tomate wire feedings with decoilers,
straightening-feeding systems and
cut-to-length lines.
While decoiling larger diameter wires
used in the production of connecting
elements, the wire spring back must
be compensated for. For this, we re-
commend the decoiler with loop arm
and spring compensation system.
Wires with a very thin diameter, used
in the production of small draft or
compression springs, loop controls
with very low wire loads are neces-
sary.
SOPREM can supply wire decoilers
equipment for both requirement pro-
ducing improved productivity.
