You might be right Margaret. Jacquard does ring a bell.
Jeremiah Jackson where I worked were general textile engineers and we made machines for the textile industry as well as going out to factories to repair or refurbish machinery.
I do vividly remember the big card with holes to make the pattern and a tackler changing them every so often.
Later looms used air or even water to blow the weft across and did away with shuttles.
We are showing our age now MARGARET.
