Take Sam Kraus, a Hungarian immigrant who founded what became Skyline Windows in 1921. In the early days, the tinsmith traveled around with a small cart to do his roofing and waterproofing work by hand.
Fast-forward to today, and the fourth-generation business, based in New York City's South Bronx, has left the pushcart era far behind. Skyline, which has evolved into a custom window manufacturer and installer, now relies on robots to do some of its work. In the factory in Woodridge, New Jersey, where it makes its windows, Skyline uses a $150,000 computer-operated machine to automate tasks like cutting holes in the metal and two $20,000 robots to install its windows, which sometimes weigh 600 pounds.
