Patent 7179333 was granted and assigned to Computrol on February, 2007 by the United States Patent and Trademark Office.
A machine for applying sealant material to non-circular closures using a rotating chuck connected to a rotational motor and a fixedly mounted dispensing apparatus. The chuck is also moved in at least one linear direction in a plane normal to the rotational axis of the chuck. The rotational motor may be connected to the chuck using various mechanisms while minimizing the moving mass of the machine. Sealant applicators are also disclosed that are mounted on a turret and use independently controlled motors, or fully integrated servomotors to rotate the chuck.
