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.
