ABSTRACT:
A restoration method and apparatus whereby a paper fiber dispenser with a vibrating motor causes paper fibers in a dry state to fall onto a disposable filter and within missing part or parts of paper being restored thereon. Paper fibers are collected and immobilized on disposable filter and within missing part or parts of paper being restored as underside of disposable filter is subjected to suction. Water-base adhesive is applied with brush to paper fibers. Paper fibers are compacted with spatula. A tensional filter counteracts pressure exerted with spatula on paper fibers. A tensional filter and disposable filter are subjected to humidity to prevent glue residue from solidifying on tensional filter and to facilitate peeling off disposable filter from restored paper. A restoration table is equipped with a tensional filter and a vacuum and humidification chamber in communication with a source of suction and a source of humidity. Suction and humidification control means are in communication with said suction and humidification sources.
