WEEFSEL VOOR EEN DROOGVILT VAN EEN PAPIERMACHINE.

摘要

A papermakers' dryer felt comprises a first surface ply 12 of machine direction monofilament yarns 22, which are beneath the paper contacting face provided entirely by the cross-machine direction yarns 14, whose peaks 16 contact from 20% to 50% of the surface area of the paper, and a second ply 20 of cross-machine direction yarns 16' bound to the first ply 12 by the machine direction monofils 22. The cross-machine yarns may be mono or multifils and the peaks 16 may be abraded to provide the required paper contacting area.
