Patent number: 6883278Abstract: Method and apparatus for making a contoured muntin bar. A supply of sheet material having a finished surface on at least one side in the form of a coiled ribbon is unwound and fed along a strip path of travel to a punch station. At the punch station a ribbon punching mechanism punches the ribbon at a precisely predetermined locations along the ribbon to form one of a plurality notch patterns that define a portion of a contoured muntin bar. Downstream along the travel path from the punch station the ribbon is fed through a forming station having a succession of forming rolls that define a succession of forming roll nips to bend the ribbon and form a generally closed cross-sectional tube. The rolls form a number of bending stages to produce a muntin bar tube having a contoured shape with raised sides to provide an attractive appearance to a muntin grid.Type: GrantFiled: August 20, 2003Date of Patent: April 26, 2005Assignee: GED Integrated Solutions, Inc.Inventors: Timothy B. McGlinchy, Mohamed Chrif Khalfoun, John Louis Grismer

Patent number: 6678938Abstract: A system for fabricating muntin bars from sheet material. Sheet material in the form of thin ribbon stock is fed to a first forming station including a punching mechanism that punches the ribbon stock at a precisely predetermined location. The ribbon stock is delivered from the first forming station to a second forming station in the form of a rolling mill. The stock passes through a succession of forming rolls to produce a tube having a desired cross-sectional shape. The tube is delivered from the second forming station to a third forming station including a severing apparatus that severs the tube at a precisely predetermined location to produce a muntin bar. After severing, the muntin bar is engaged by a conveyor and moved to a desired location.Type: GrantFiled: April 8, 2003Date of Patent: January 20, 2004Assignee: Glass Equipment Development, Inc.Inventors: Timothy Bryan McGlinchy, Mohamed C. Khalfoun, John Louis Grismer, Michael J. Gardner
