Abstract
A papermachine belt particularly for use in a press and/or dryer section comprises a support fabric, a minimal nonwoven layer on the support fabric, a fusible thermoplastic layer, and a thicker batt over the thermoplastic layer. The whole structure is needled together, and the thermoplastic layer melted so that it is expressed through the overlying batt. The layer may be substituted by a nonwoven fabric containing composite yarns with thermoplastic sheaths or such yarns wound spirally around the belt. The support fabric may be substituted by a perforated composite membrane.
