Primer applying and surface wiping apparatus

摘要

A primer applicator which is movable along a surface of a workpiece such as an automobile window glass panel has a rotatable primer coating roller having an outer circumferential layer of soft resin. A robot arm which supports the primer applicator is actuated to move the primer applicator along the surface of the workpiece in rolling contact therewith to apply a primer to the surface of the workpiece. The primer is supplied to the outer circumferential layer of the primer coating roller when the primer coating roller rolls on the surface of the workpiece.
