Paper Processing & Conversing
Review Paper Size Required
To reduce changeovers and stocking requirements, paper companies
often standardise on a limited range of web widths. Review
carefully whether these are the most appropriate for the range of
cut sizes required, as the amount of trim may be able to be
reduced.
Ensure sheet counters are accurate with periodic
checks
Sheet counters are often set to count a few extra sheets for
safety. Periodic checks can identify the problem early and allow
corrective action, reducing giveaway.
Collation
In the collation process, each reel change causes waste of other
parts. To minimise stoppages operators may replace a part reel as
well as the one which is exhausted. Standardising reel lengths
means that all parts are changed together, minimising stops and
waste.
Reduce cores down to the minimum
The risk of breaking the web may lead to caution in running reel
cores out. Maintain or replace brakes, introduce better speed
control and introduce operator graphing of core waste.
Run reels as large as possible
Running the largest reels possible minimises changeover waste and
time.
Monitor and plan
Monitor print quality during the run and plan coating mix
quantities carefully
