Producer of Laminates and Performance Films Increases Capacity and Cut Quality with Retrofit Section
A producer of laminates and performance films used for
tents, banners, movie screens and pool liners approached Double E with a
problem they were having. The rubber/vinyl material they were running
had various thicknesses at a web width of 84" with a minimum slit of 2"
and a maximum speed of 75fpm. The customer had a problem with their
slitting section which was setup with razor cut blades. When running
thicker material through the line at higher speeds, the blades would
wear down too quickly which resulted in continuous machine shutdown.
This excessive downtime lead to lost profit and the customer needed a
solution to significantly reduce this problem. The customer turned to
Double E for a solution.
Double E engineered a new retrofit
slitting section upgrading the line to shear system using the Mario
Cotta "Gold" seriesknife holders and "Expandette" removable bottom
knives. This tried and true combination provided the customer with
superior slitting quality and efficiency. The "Gold" holder provided
longer blade life, superior cut quality, quick blade changes, and easy
calibration once the blades have been resharpened. The "Expandette"
removable bottom knives provided additional reduced maintenance time
with rings that are easily replaced without removing the anvil from the
shaft. These holders and bottom knives were mounted on a custom retrofit
stand that easily bolted to the machines existing frame providing a
seamless upgrade.
The customer has since expressed
how pleased they are with the new slitting section since the solution
not only provided better efficiency and less downtime but also provided
flexibility in mounting razor cartridges if they needed to run thinner
material. The customer also expressed that this was the easiest retrofit
he has ever done. The stand bolted right into the existing holes and
didn't require any additional modifications. Now the customer is able to
run the line longer with superior cut quality and minimum maintenance
downtime.
