Davis will also introduce the dsX flex-pack extrusion coating line, a pre-engineered system aimed at processors looking for a quick, versatile entry into the extrusion-coating market.
Called the dsX stretch, the 2-meter-wide line reportedly offers a small footprint and can be supplied within a six-month lead time with both five- and seven-layer options. In flat film, Davis-Standard, Pawcatuck, Conn., will introduce what it says is the first in-line pre-stretch system for cast film that enables processors to run thinner at higher speeds. This profile runs continuously, even during oscillating hauloff reversals. It’s called the Addex Mapper, a stand-alone device that directly accepts most thickness profiler system profiles and then automatically takes into account all the twists, turns, and undulations of the bubble to create a fully “mapped” thickness profile with better than 1° accuracy. For a fully integrated autoprofile control algorithm, operators just input an already mapped 360° thickness profile and the system will determine the best control action and seamlessly pass this to the cooling adjustors of the air rings.Īddex also has a solution for processors that have an existing thickness profiler but don’t have the ability to sort through all the intricacies of line speed. The new system also provides direct control of even higher resolution air flow within Addex’s internal bubble cooling (IBC) system, using the same interface as for the cooling ring. Operators just input a 360° profile of desired cooling-air flow, and the air ring takes it from there.
These functionalities include direct control of the high-resolution air flow within the dual-flow cooling ring.
