The use of NRD’s static eliminators for multi-product printing runs on lighter weight papers resulted in a 20% to 30% increase in production for one Wisconsin printer.
Specializing in publications, the printing company utilized a Goss web press with a 34.5” cut-off and 46.5” maximum width. Operating at 1,000 feet per minute the press prints up to 32 pages on 40 to 80 lb. bookweight publication stock.
The printing plant previously experienced problems with lighter weight, multi-product signatures sticking together because of static – particularly in the wintertime.
“The lead time of paper to press is often short in our plant because of a lack of storage space,” explains the plant manager. “Dry, cold weather causes static on 40 to 50 lb. papers, making four and eight-page printed signatures stick together in the folder. This slows down jogging and limits the speed of the press.”
To solve the problem, the company installed an Alpha static eliminator bar on each of the two outfeeds of the Goss folder. Mounted in brackets directly above the signatures as they leave the folder, the static eliminator removes static changes from the forms and prevents them from sticking together. Completely portable, the units are easily mounted and can be removed at any time.
“Previously, we might have had to use as many as four joggers on a four-page, 45 lb. signature,” says the plant manager. “With the eliminators, we only need two, plus a little help from a third. Overall, through such economies and increased production, the eliminators paid for themselves very quickly.”
The printer also uses two Alpha static eliminating bars equipped with NRD’s proprietor induction brushes on printing sections of the Goss press to eliminate the possibility of pressmen receiving static charges or shocks from the press.
The firm is using its present eliminators interchangeably on the Goss press and the newer press. Since the eliminators require no cords or wires and can’t generate sparks, they are recommended for use even in highly volatile plant areas.
