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.
Claims10
A notching system configured to notch lineal material to be foldable into a window frame, said system comprising:
- a cutter configured to notch the lineal material;
- and
- a controller configured to position at least one of the lineal material and said cutter and to activate said cutter to produce notches in the lineal material defining first and second end sections and an intermediate section of a window frame, said controller further configured to adjust the length of said intermediate section relative to a finished production length by a first stretch treatment of up to about 0.5 in. and the length of one of said first and second end sections by a second stretch treatment of up to about 0.25 in.
