Rewinders-A Look at the Future
REWINDERS PLAY AN important roll in today's print shops and can make or break a great print run. For example, registration can be right on the mark, color can be perfect, then Whammo!, during the rewinding process the entire roll can "telescope" into a useless pile of wound-up trash.
"Maintaining uptime and reducing downtime on the rewinder has been a goal for some time," said Brian Ivens, manager, sales and marketing, Arpeco. "Quality of design and manufacturing has always been a significant method of providing reliability and dependability with equipment." There are many reasons the rewinding process can be a problem, but knowing what new technologies are available out there, or knowing some tricks of the trade, can reduce some of the stresses in the print shop.
The 2005 holiday season is over. The last of the wrapping paper is thrown out, the remains of the cookies have been eaten, and the last of the champagne has been drunk. And more importantly, your list of New Year's resolutions is complete. And maybe running a smoother converting process is the first resolution on your list. Or at least, near the top right under "eat less cookies and drink less champagne."
Knowing how to improve your package-printing operation involves an understanding of what's available in new off-press equipment. As with almost all technologies in today's world, "new" equipment can usually be boiled down to "more automated" machinery.
Craig Thomson, marketing manager, Martin Automatic, agrees with this statement. The recent advancement in the rewinder industry, "in general, is the level of automation available, especially, the emergence of AC vector drives and motors," he said. Other advances include "differential winding for slit ribbons and, as with all machinery, advances in ergonomics and safety features," he added.
One example of this automation, Thomson said, is Martin Automatic's LRD model rewinder, which now comes equipped with quick-setup slitting, differential (or slip-core) winding, automatic roll unloading, and a lift table to present the slit rolls at a comfortable height.
