ABSTRACT:
An exemplary embodiment of the invention concerns a process for forming two tone muntin bars. Method and apparatus of the invention uses an elongated preformed muntin bar member that has a treated portion of an exposed surface of the muntin bar member. An elongated strip of covering material is provided for controlled application onto a specified portion of the treated portion of the muntin bar material. The elongated strip of covering material includes an adhesive that causes the covering material to adhere to the muntin bar member. The muntin bar member and the covering material are brought into contact with each other to cause the covering material to overlie and adhere to the muntin bar member.
