Heavy Duty Knife Holder Solves Stability Problems for Heavyweight Paper Producer
A producer of 200Ib specialty paper approached Double E
about concerns regarding the instability of their Tidland class III
holders at the cut point. At high web speeds of 6,000 fpm the blade
would shake due to the narrow dovetail rail and construction of the
holder itself. This would cause rejected rolls, which forced the
customer to shut down the line often and throw out wasted material. The
dovetail rail not only added to the instability but also increased the
overall setup time due to the difficulty in positioning the holders.
Safety was also a concern, since the blades were always exposed,
increasing the risk of a potential injury.
Double E recommended the new Mario
Cotta "Platinum" series high performance, heavy duty knife holder with
upgraded rack and pinion rail system. This robust holder features a dual
shaft design that provides stability at the cut point, improving the
cut quality even at high speeds. The precise and consistent control of
the overlap, cant angle, and side load gives the operator confidence
that the slit quality and accuracy of every roll is the same. The user
friendly setup knobs allows the operator to set each knife the same way,
which yields consistent results from knife holder to knife holder and
shift to shift. Removable blade cartridge makes it safer to change
blades and allows operators to reduce downtime by swapping in a new
cartridge. The new rack and pinion rail provides a smooth, accurate
positioning that adds to the improved finish roll quality and reduced
downtime.
The new upgrade provided
efficiency, cost savings, and increased product quality. The customer
has since expressed how well the slitter machine performs but what the
customer was most impressed with is the level of safety that the new
Platinum holders provide. Since the blade cartridges could be removed
before changing out the blade there was reduced concern for any operator
accidents. The full protective guards added to the overall safety of
the holders.
