What it is
A flexible steel blade closed in a loop that runs over two wheels and cuts continuously in one direction. William Newberry patented it in 1808, and it was not practical until the band could be welded, which Anne Paulin achieved in Paris in 1846.
Newberry had the idea and his patent dates to 1808, but there is no record of working machines; the practical band saw is credited to Anne Paulin (1846), who patented the method of welding the blade.
What it led to
- curved cuts and board cutting with little waste in the sawmill
- butchers' and metal-cutting band saws
- marquetry and cabinetmaking workshops
Built on
