The Double E Company has worked closely with many
customers over the years regarding solutions to slitting
dilemmas. Recently a customer in the tissue industry
came to Double E looking to upgrade from the
tried and true Mario Cotter PPS model to a newer
knife holder. The customer was able to get many
years of service from the PPS but dust was starting to
build up due to the excessive cant angle on the holders
and worn out multi‐groove anvils. Another problem
was that the holders were located inside their
Fabio Prerini Slitter/Rewinder machine with very limited
access and they needed a holder that provided
easier blade changes. Double E introduced the customer
to the "Gold" series knife holder by Mario
Cotta.

The production manager agreed to purchase a Gold
series holder for a brief trial period. Since the customer
was upgrading to a newer Mario Cotta device,
the drop‐in replacement was effortless. The production
manager was intrigued by the knife holder's
mounting flexibility and once the production line
started using the device, he soon realized the benefits
of the error‐free cant angle adjustment and the blade
guard safety feature. The line operators found it easier
than ever before to replace blades…because the
simple cartridge system allows them to pull one out
and replace it without tools.

The production manager was so pleased with the
"Gold" series knife holder that he immediately outfitted
his entire production line with "Gold" series knife
holders and multi‐groove anvils. These Mario Cotta
holders save time, yield unparalleled cut quality, and
alleviate the dust issue. He also has the peace‐ofmind
of knowing that parts availability and product
support are never a problem with Mario Cotta.
