Patent ID: 7097805

Claim:
A method for manufacturing slippery-proof foam material having protruded threads, comprising the steps of: using Thermoplastic Elastomer (TPE) or EVA (Ethylene Vinyl Acetate) pellets to produce a foam material plate; attaching a high heat resisting mesh cloth having a plurality of meshes with a predetermined size onto at least one side of said foam material plate, and then using a heating device to heat said foam material plate until said foam material plate is softened to the extent of being suitable for a plastic formation; and using at least one mold to press said foam material plate, wherein said mold for covering said foam material plate and having one of its sides being pressed by said high heat resisting mesh cloth comprises a plurality of tiny grooves evenly disposed on at its surface, such that a section receiving a larger pressing force of said foam material moves towards a section receiving a smaller pressing force of said foam material when said foam material is pressed for plastic formation, and said foam material passes through said meshes to form an even protruded thread at the position corresponding to said each mesh on the surface of said foam material plate.
