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.
Claims7
A system for making muntin bars comprising:
- a) a conveyor for moving elongated preformed muntin bar members that have been treated on at least a portion of an exposed surface;
- b) a supply of an elongated strip of covering material for controlled application onto a specified portions of first and second surfaces of a muntin bar member, said covering material comprising an adhesive for adhering the covering material to the muntin bar member;
- c) a drive system for moving the covering material into contact with the preformed muntin bar member;
- d) a first pressure roll that applies pressure to a region of engagement between the first surface of the muntin bar member and the covering material;
- and
- e)a second pressure roll that applies pressure to a region of engagement between the second surface of the muntin bar member and the covering material.
The system of claim 10 wherein the first pressure roll applies pressure to a region of engagement between a top surface of the muntin bar member and the covering material, and the second pressure roll applies pressure to a region of engagement between the a side wall of the muntin bar member and the covering material.
