Card Vacuums

A modern card that is well made always comes with a sophisticated vacuuming system. The purpose is two-fold.

  1. The vacuum keeps the card clean, primarily around the sides of the main cylinder and other rolls and inside the hoods.
  2. 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.
