Davis-Standard LLC’s Converting Systems group in Fulton, N.Y., recently delivered its first high-speed, four-spindle “Black Magic” S4 center winder in North America. Four spindles index almost twice as fast as two (0.75 sec vs. 1.2 sec), reducing scrap during indexing. The latest S4 winder is for 3.4-meter-wide stretch film, but it can wind on 2- or 3-in. core shafts. It’s available with both bleed trim for a variety of web widths or bleed-less configuration for more dedicated roll widths. The S4 can wind 1000-ft-long (300-m) rolls of stretch film in 25 sec, or 2400 ft/min. The S4 winder was first introduced at NPE 2006 in a center/surface version without bleed trim.
