Wide Belts
 Wide Belts - Gates Mectrol  

Gates Mectrol can produce urethane timing belts in widths up to 450 mm. This belt is specifically designed for synchronous conveying applications. 

Wide belts are primarily used as process conveyor belts. Process (or conversion steps) normally occur on the belt, therefore the conveyed product requires additional width.
