Method for manufacturing sheet laminate, mold for molding sheet laminate, and sheet laminate

Abstract

A method for manufacturing a sheet laminate to be affixed to an adherent surface of an object, the method comprising preparing a sheet member having a front surface to become a design surface and a rear surface on which an adhesive part has been formed, bending an edge part of the sheet member by sandwiching the sheet member from a front surface side and a rear surface side in a mold, and heating a part of a bent sheet member. The sheet laminate has a flat part spreading out in a flat plate shape, a side surface on which the edge part bent by the bending step is configured, and a connecting surface protruding and curving toward the front surface side between the flat part and the side surface, and in the heating step, the connecting surface is partially heated after the side surface is molded in the bending step.

What is claimed is: 
     
         1 . A sheet laminate manufactured according to the method comprising
 providing a sheet member having:
 a) a front surface to become a design surface and 
 b) a rear surface on which an adhesive part has been formed; 
   bending an edge part of the sheet member by sandwiching the sheet member from a front surface side and a rear surface side in a mold to create the sheet laminate; and   partially heating the connecting surface after the side surface is molded in the said bending, and   wherein the sheet laminate has a flat surface part spreading out in a flat plate shape, a side surface on which an edge part bent by said bending is configured, and a connecting surface protruding and curving toward the front surface side between the flat surface part and the side surface   wherein the connecting surface does not contact the mold during the partial heating, and partial heating is performed by applying heat to the connecting surface from outside the mold,   wherein a part configuring the flat surface part, the side surface and the connecting surface is configured of a base material layer having a front surface that is to become a design surface, and a rear surface on a side opposite the front surface, an adhesive layer formed on the rear surface of the base material layer, and a release liner layer covering the adhesive layer that can be peeled from the adhesive layer.   
     
     
         2 . The sheet laminate according to  claim 1 , further comprising:
 a main body part for configuring the flat surface part portion of the sheet laminate; and   a pair of side wall parts each extending respectively toward the rear surface side from a pair of mutually intersecting side parts of the main body,   wherein the side surface has a first side surface corresponding to one side wall part of the pair of side wall parts, a second side surface corresponding to the other side wall part of the pair of side wall parts, and a third side surface forming a roundness having a predetermined curvature formed in a corner part between the first side surface and the second side surface; and the connecting surface has a first connecting surface for connecting the flat surface part and the first side surface, a second connecting surface for connecting the flat surface part and the second side surface, and a third connecting surface for connecting the flat surface part and the third side surface.   
     
     
         3 . The sheet laminate according to  claim 2 , wherein the third side surface forms the roundness protruding toward the front surface side, and a curvature of the roundness has a radius in the range of from about 1 mm to about 2000 mm. 
     
     
         4 . The sheet laminate according to  claim 2 , wherein the third side surface forms the roundness protruding toward the front surface side, and a curvature of the roundness has a radius in the range of from about 0.5 mm to about 2000 mm. 
     
     
         5 . The sheet laminate according to  claim 1 , wherein the base material layer is covered by a biaxially extended protective film layer. 
     
     
         6 . The sheet laminate according to  claim 1 , wherein the release liner layer is configured of a biaxially extended protective film layer. 
     
     
         7 . The sheet laminate according to  claim 1 , wherein the adhesive layer is configured using an acrylic pressure-sensitive adhesive. 
     
     
         8 . The sheet laminate according to  claim 1 , wherein the base material layer is configured using a polycarbonate.
