Gerber Scientific has announced plans to close its Gerber Coburn plant in Muskogee, Oklahoma, home to its ophthalmic business, by April 2005, and plans to move operations to its other locations, mostly in Connecticut where its headquarters are based. The Muskogee plant employs 130 people, most of whom will be laid off. The move should result in charges of $3.4 million but generate annual savings of $1.3 million for the current fiscal year and around $3.0 million from next year on.
