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.
