Gavehren

Ga-Vehren was founded in 1966 to provide mechanical enhancements and productivity improvements for those involved in envelope, print and direct mail production. Early designs were in high-speed, rotary vacuum-folding, and paper transport. Additional projects led to edge gumming equipment and the world's dominant, offline envelope latex- gumming machine called The Gum Master", marketed by W & D Machinery of Overland Park, Kansas USA.
