Arkwright's carding machine, 1775.
Carding machine by Arkwright, 1775, believed to be from Cromford Mill. This machine is similar to the cylindrical carding machine patented by Daniel Bourne in 1748. The cotton was first ginned and beaten, then fed on to the feed roller, called a "licker in". Its wire teeth are bent towards the direction of motion so that they lay hold of the fibres of cotton and carry them downwards and round to the main roller. This has a surface speed about 80 times that of the licker in, and thus combs the fibres and straightens them as well as taking the fibres off the first roll. The third roller or doffer moves at about 1/10th of the main roller surface speed in the same direction but as its teeth are set in the opposite direction it removes the cotton from the main roller. A reciprocating comb takes the carded cotton from the doffer and delivers it in strips or slivers.
