Film Wrapping — A Nice Finishing Touch
"The 55GI-20C has separate and infinitely variable speed drives on the infeed and tunnel belts, allowing customers to change speeds and temperatures on-the-fly," Anderson remarks. "This means that they can optimize the most efficient use of time and energy consumption."
In terms of options, ARPAC offers a short stroke cylinder kit that allows printers to increase bundle throughput from 55 to 65 per minute on bundles under 6" high.
The demand for shrink wrapping systems has greatly increased in the commercial printing market over the past decade, according to Todd Hiser, vice president and general manager of Clamco Corp.
"Commercial printing operations depend extensively on the superior protection and cost efficiency," Hiser states. "This huge demand requires extremely dependable, highly efficient systems designed with the standard features and readily available options to deliver high throughput rates at low operating costs."
According to Hiser, Clamco offers standard features not found on most competing systems. They include the Model 120 L-sealer/tunnel combination system with 120-volt operation and the high-speed 1700 Series. The Model 120 has standard features such as unitized package tray and film cradle with pinwheel perforator, large shrink tunnel and 11-gauge steel construction.
With large inserts and various media such as CD-ROMs accompanying publications, security at newsstands becomes an issue. This fact augments the important role of the wrapper, reveals Felix Stirnimann, division manager, print finishing operations, for Muller Martini.
Piggyback mailings—two catalogs to one address—can save on postage and enable margins to be met. He also points out the increasing demand for one-pass operation, bringing the inserting/wrapping segments in-line with the finishing system.
Muller Martini offers the dual system of the Onyx inserter and Rubin film wrapper. The Onyx features a regular stack-pile feeder for loading brochures or single sheets, and a twin feeder for side-by-side card placement. Maximum size of products fed is 16.5x12.25", with a top speed of 18,000 cph. The Rubin can wrap from the bottom up or from the top down. Both units are servo driven.
