Abstract: A method for continuously manufacturing anti-slippery chopping boards, and the method uses a bottom mold pressing machine to provide a plastic mold board from the material output mold; the plastic mold board goes through a set of rollers for setting its thickness and is fed to the bottom of the mouth of an anti-slippery material pressing mold with the same width the after a preliminary setting is completed; a fixed-distance scraping board disposed at a material output position on a material transporting roller is used to produce rectangular anti-slippery meshes on the manufactured sheet anti-slippery material by intermittent scraping, so that the anti-slippery meshes can be formed and attached onto the surface of the plastic mold board simultaneously, while the plastic mold board is still not completely solidified. The finished good of the anti-slippery pad is seemingly an integral structure with one layer.
