Wool carding is the process of brushing the wool fibers with wire teeth to align the fibers. Wool carding machines were developed in 1748. Before that time wool processing was done by hand as a "cottage industry".

The carding machines currently in use at Custom Woolen Mills were all built in the U.S.A. and date from 1895 to 1927. They are used to card roping, batts, and spools of carded yarn for spinning. Our original batt carding machine which is now being prepared as a display piece, was built in the 1860's and came from England.
