ABSTRACT:
The present invention discloses a method for manufacturing slippery-proof foam materials having protruded threads, which comprises the steps of foaming Thermoplastic Elastomer (TPE) or EVA pellets into a foam material plate, attaching a high heat resisting mesh cloth onto the surface of the plate, heating the plate by a heating device to soften the material to an extent of being suitable for a plastic formation, rolling and pressing the plate by a rolling mold or a piece of mold having an even surface and a plurality of tiny grooves thereon, so that the section of the plate receiving a larger rolling and pressing force moves towards the section receiving a smaller rolling and pressing force, and then passes through the meshes of the high heat resisting mesh cloth under the condition of being held up by the high heat resisting mesh cloth to form evenly protruded threads on the surface thereof after being cooled immediately.
