Vignette from a lithographic plate showing two young men carding wool using a drum carding machine. Carding is the combing and disentanglement of fibres prior to subsequent spinning proceses. The fibres are pased between a series of rollers which rotate at different speeds, blending and refining the fibres into a higher quality product known as 'roving', which can then be spooled and finally spun into thread. Taken from 'The Sheep' in 'Graphic Illustrations of Animals - Showing Their Utility to Man in Their Employment During Life and Uses After Death', a book illustrated by Benjamin Waterhouse Hawkins. Printed by J Graf. Published by Thomas Varty.
