A modern card that is well made always comes with a sophisticated vacuuming system. The purpose is two-fold.
- The vacuum keeps the card clean, primarily around the sides of the main cylinder and other rolls and inside the hoods.
- The edge of the webs on the doffers are vacuumed to catch any clumps that may build up on the edges and to maintain a consistent web width out of the card.
