Abstract
To protect the paper machine fourdrinier screen, deckle blades are fabricated with a soft polymer (polytetrafluoroethylene) lower edge having little adhesive affinity for either papermaking fiber or traditional plastic bonding compounds. Necessary structural rigidity is contributed to the assembly by a mechanical cladding of suitably stiff polymer plates that are adhesively bonded to a compatible plastic mounting body.
