Lightweight
Rolls Improve Printing Operation
Webex helped a printing company increase speeds and reduce downtime
while running lightweight paper.
A local printing company specializing in
printing lightweight papers for catalogs and newspaper inserts
approached Webex looking for help. This customer runs twenty-year-old
Harris presses. The trend in the industry is to run lighter and
lighter paper.
While the Harris press ran well with the middleweight stock it
was designed for, it struggled badly trying to run lightweight stock.
Web breaks were common during start-up especially when the first
wet impression was made. Webex analyzed the situation and determined
that the heavy weight of the original idler rolls throughout the
press was the single most likely contributing factor in the frequent
web breaks.
Webex helped the customer reconfigure these presses using Webex
LW-400-150 x 42" face aluminum
idler rolls. These "LIGHTWEIGHT" idlers reduced the
weight and inertia of the idler rolls in the press by over 50%.
After installation our customer reported that the web break issue
was substantially reduced and as a bonus the press was able to run
at faster speeds with less scrap. Further analysis by our customer
documented an investment payback of less than 6 months. Subsequently,
this success has been duplicated on presses of other makes as well.
