Abstract

In the use of an assembly line electrostatic painting booth, the rub rails, which impart rotary motion to the hangers and thus rotate the parts being painted, become coated with paint during the normal operation. When the rub rail is constructed of a rubber material to increase the friction and improve revolution of the painting brackets, the rubber is coated with paint and the removal of the paint with ordinary solvents deteriorate the rubber rapidly. Further, ordinary rubber does not give sufficient frictional force to the spinners of the paint brackets to insure even rotation.

Magnetic Rub Rail

In the use of an assembly line electrostatic painting booth, the rub rails, which impart rotary motion to the hangers and thus rotate the parts being painted, become coated with paint during the normal operation. When the rub rail is constructed of a rubber material to increase the friction and improve revolution of the painting brackets, the rubber is coated with paint and the removal of the paint with ordinary solvents deteriorate the rubber rapidly. Further, ordinary rubber does not give sufficient frictional force to the spinners of the paint brackets to insure even rotation.

This is overcome by the use of a magnetic rubber 1 which is placed on the rub rail 2 and magnetically held in place. The magnetic effect of the magnetic rubber 1 is to attract the steel spinner 3 on the paint brackets, thereby increasing the frictional engagement between the rub rail surface and the spinner. The increase in frictional force insures uniform rotation of the objects to be electrostatically painted. To aid in the cleaning and removal of paint from the surfaces of the magnetic rubber 1, the segments of magnetic rubber 1 are encased in a heat shrinkable TEFLON* tube 4 and the tube is then shrunk to conform to the magnetic rubber shape. The heat shrinkable TEFLON material 4 protects the magnetic rubber 1 and at the same time is readily cleanable with normal paint cleaning solvents. The magnetic rubber rub rail material 1 may be removed from the rub rail bracke...
