The disclosed apparatus and method automatically secures three substantially planar sheet members in registration with respective portions of a sheet of material such that (1) one of the sheet members is centered between the other two, (2) the outer oppositely disposed edges of the other two are mutually spaced from one another by a predetermined distance as well as precisely positioned with respect to a first edge of the sheet of material, and (3) another edge of each of the other two sheet members is substantially aligned with the other and with an edge of the center sheet member, all of the aligned edges of the members being precisely positioned with respect to a second edge of the sheet. |
