METHOD AND DEVICE FOR MANUFACTURING FILM LAMINATE HAVING IMPROVED DURABILITY TO BENDING IN ALL DIRECTIONS

摘要

PROBLEM TO BE SOLVED: To add "a feel of a material" and improve rigidness and elasticity of a film in all directions without sacrificing characteristics of a laminate or a general dimensional structure-like appearance and without damaging punching and tear propagation resistance.;SOLUTION: The lamination is conducted by making two layers for lamination contact directly each other and applying heat and pressure to them. A laminating means is applied to limit joining to a joining area arranged in a continuous or discontinuous linear line extending in a direction generally perpendicular to a mechanical direction of the lamination. After the lamination shrinks the first layer in a solid state in the shrinking direction, the lamination bends the non-joining area of the second layer and forms a groove extending in a direction perpendicular to the shrinking direction.;COPYRIGHT: (C)2011,JPO&INPIT
