Drafting

draftingFrom the carder, the barrels of sliver move to the draw frame and a process known as "drafting" or "drawing". The draw frame is made up of spiked cylinders running at different speeds. Two or more slivers are combined and as they pass through the rollers, their thickness is reduces by a "pulling and stretching" process. The sliver exits the draw frame much thinner and lighter in weight than at the start and is now called a roving. Multiple passes and doubling of the slivers, results in a fine even roving, ready for spinning. The roving is exceptionally fragile and breaks apart very easily.
