| 摘要 |
The present invention discloses a method for manufacturing slippery-proof foam materials having protruded threads 90, which comprises the steps of foaming Thermoplastic Elastomer (TPE) or EVA pellets into a foam material plate 21, putting a high heat resisting mesh cloth 40 onto the surface of the plate 21, heating the plate 21 by a heating device (60) (figure 2 - not shown) to soften the material to an extent of being suitable for a plastic formation, pressing (or rolling) the plate 21 by a pressing (or rolling) mould 70,71 having an even surface and a plurality of tiny grooves 80 thereon, so that the section of the plate receiving a larger pressing (or rolling) force moves towards the section receiving a smaller pressing (or rolling) 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 90 on the surface thereof after being cooled immediately. The mesh cloth 40 may be removed (figure 4). Cooling water may be circulated inside the moulds. |
