In the carding opener the wool fleeces were placed on a conveyor belt and passed between two cylinders and then deposited in the drum. The different speed and direction of the barrel of the drum with respect to that of the cylinders caused the fleeces to open and transformed them into a fine layer, called sheets. The first mechanical carding opener dates back to 1748.
