Abstract
A rugged shaped sheet capable of exhibiting improved non-slip properties and aesthetic properties and a process for manufacturing the same. The rugged shaped sheet includes a base sheet member and a rugged pattern of a predetermined shape adhered to the base sheet member. The rugged pattern is formed of a plurality of pattern elements different in size, configuration and/or properties into a multi-layer structure. The rugged shaped sheet is manufactured by pouring an elastomer liquid material into each of perforated plates, semicuring the elastomer and laminating the perforated plates on each other, resulting in forming the rugged pattern of a predetermined shape on the base sheet member.
Claims16
A rugged shaped sheet comprising:
- a base sheet member;
- and
- a rugged pattern of a predetermined shape adhered to said base sheet member;
- said rugged pattern comprising at least two projections;
- each of said projections comprising at least two solid cured elastomer pattern elements laminated to each other in such a manner that said pattern elements, at the same distance from said base sheet member, are comprised of the same material, and wherein said pattern elements are formed so as to be different in at least one of size, configuration, color, hardness, elasticity, shock absorbing capability, luster and satinizing from each other, said pattern elements being formed by using at least two perforated plates including perforations and repeatedly carrying out a set of steps comprising arranging one of said perforated plates, pouring an elastomer liquid material into said perforations and semicuring said elastomer liquid material;
- and thereafter completely curing the elastomer material.
