Carding and Pindrafting
Carding is done on a machine with a large drum that is clothed with fine teeth. These lay all the fibers into a consistent web with the fibers overlapping each other.
After carding the wool goes through another machine called a pin drafter. This machine has a series of fallers that draft and refine the fiber into a more consistent sliver that can be machine spun, hand spun or felted with. Because the fibers are more parallel, it drafts easily.
