Abstract
A felt provides a uniform paper-supporting surface having good water storage and water release properties. These qualities are effected by a bat including one or more layers of fine fibers being needled onto a base containing perforations and cavities. The free surfaces of the bat fibers needled into the cavities are reduced in a special production step following the needling operation.
