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.
Claims20
A process for making muntin bars comprising the steps of:
- a) providing an elongated preformed muntin bar member having an exposed surface having a treated portion;
- b) providing an elongated strip of covering material for controlled application onto a specified portion of the treated portion of the muntin bar member, said elongated strip of covering material including an adhesive for adhering the covering material to the muntin bar member;
- and
- c) bringing the muntin bar member and the covering material into contact with each other to cause the covering material to overlie and adhere to the muntin bar member.
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 portion of a surface of a muntin bar member, said covering material comprising an adhesive for adhering the covering material to a muntin bar member;
- c) a drive system for moving the covering material into contact with the preformed muntin bar members to cause the covering material to overlie and adhere to a surface of the muntin bar member;
- and
- d) a pressure roll that applies pressure to a region of engagement between the muntin bar members and the covering material.
A process for making multiple two tone muntin bars for a muntin bar grid comprising the steps of:
- a) providing a series of elongated muntin bar members that have been cut to a length suitable for inclusion into a muntin bar grid, which has been treated on an outer surface, and feeding the muntin bar members along a travel path;
- b) providing an elongated strip of covering material for controlled application onto a specified portion of the outer surface of the muntin bar member, said elongated strip of covering material including an adhesive for adhering the covering material to the muntin bar member;
- and
- c) bringing the covering material into contact with the muntin bar members as they move along their travel path to cause the covering material to overlie and adhere to the muntin bar members to form a series of elongated preformed muntin bars which are subsequently assembled into a muntin bar grid.
