label: Description
content: Textile production was a complicated business, involving hundreds of machines, and thousands of calculations, many of which had to be conducted by the weaver or loom-fixer in a few seconds of down-time to keep production moving and prevent losses from damaged goods. As the machinery grew more and more complex during the 20th century, and workers supervised more and more machines, these calculator cards provided assistance with complex calculations essential to efficient production – until the machinery was, by and large, replaced by computer-controlled equipment, in which adjustments were made in a central location. The NMAH array of calculator cards illustrates a sampling of the categories of computations that mill workers made daily, from fiber to finished cloth. They provide important context about the labor involved in running the machines they relate to.
