Abstract
A system and method for producing window components using polymer based, metallurgy based, extruded, injection molded, or wooden lineal material. The lineal material is notched at intervals calculated to include a stretch treatment and folded to form window components such as window sashes, frames, and the like. Internal reinforcing members may be welded within the joints formed by folding at the notches. The notching system and method provide low cost, highly reliable, low defect production of multi-sided window components from a continuous piece of lineal material.
Claims22
A method of notching lineal material for folding to produce a window frame, said method comprising:
- receiving lineal material at a notching machine;
- and
- activating said notching machine to form notches in the lineal material defining a plurality of elongated window frame sections wherein the length of a first of said sections is reduced from a first desired finished dimension by up to about 0.25 inches and the length of a second of said sections is reduced from a second desired finished dimension by up to about 0.5 inches.
A method, comprising:
- receiving lineal material;
- and
- notching the lineal material to form a plurality of sections;
- wherein the length of a first section is shorter than a first finished dimension by a first distance,
- wherein the length of a second section is shorter than a second finished dimension by a second distance, and
- wherein the second distance is about twice as large as the first distance.
A method, comprising:
- receiving, at a control processor, a data profile associated with a material;
- computing a notching sequence for the material in accordance with the data profile;
- creating a plurality of notches in the material in accordance with the computed notching sequence;
- inserting a reinforcing member into at least one notch;
- folding the material to form at least one corner;
- and
- fixing the material in place at the at least one corner.
