As a result of logistics problems, Davis-Standard had to scratch its plans to exhibit a redesigned 4,400 mm (180 in.) Culisse winder. Nonetheless the winder, which saves time and money by slitting and winding in-line, rather than in separate steps, is still proving popular with customers. The company has delivered 15 of the winders to customers in North America and Europe in the last 18 months, according to Chris Barton, Crompton, Davis-Standard business manager, blown film, cast film.
“The real advantage of the winder is that you do not have to take bleed trims when indexing the new core into the transfer position,” said Barton. He noted that this is a faster, more efficient process compared with a standard turret winder which produces scrap during the index cycle of the entire roll.
The Culisse is capable of in-line slitting to widths of 75 mm across a 3,000 mm web at speeds up to 600 m/min. The winder has been redesigned for the K Show. New elements include a control system that simultaneously controls both web tension and lay-on pressure, and some redesigned mechanical parts. The winder is being used in applications involving multi-slit hygiene film, PE film packaging, specialized multi-layer barrier film, and others, according to Barton.
