In 1832, John I. Howe patented the first successful USA pin making machine and shortly afterwards he formed the Howe Manufacturing Company (a patent was issued in 1832). Before long, the company was making 70,000 pins a day. The pins still had to be manually packaged, slowing down the production process. So in 1843, Howe and some employees developed a machine that crimped paper and inserted the pins.
From the 1850's onwards pins were produced on a large scale in the USA and became cheap, readily available items.
