Abstract
A press felt includes a base structure providing dimensional stability in a machine and a cross machine direction of the felt, a batt fiber structure including batt fiber layers attached to the base structure which provide a paper contacting side and a machine contacting side of the felt. The base structure includes a first and second side. Polymeric beads or strands made from a polymeric material are arranged on at least one of the two sides of the base structure. The polymeric beads or strands arranged on the at least one side have a longitudinal expansion in the machine direction of the felt and are arranged side-by-side when viewed in the cross machine direction of the felt to generate space between adjacent beads or strands. At least one of the batt fiber layers is arranged to cover both the at least one side and the polymeric beads or strands thereon.
