Abstract

Provided are a technique for realizing a laminated plate capable of improving the appearances of end portions and the degree of shaping freedom, and a terminal treating method for a laminated material. As shown in the Fig.1, when a cooling-press upper mold (80) drops, a design forming protrusion (82) pushes both a portion of a surface member laminated material (1d) on the inner side of a deposited portion (6a) and an inclined end portion (6b) downward. On the other hand, the untreated portion of the surface member laminated material (1d) is pushed to a forming face (72) of a lower face (81). Both the portion of the surface member laminated material (1d) on the inner side of the deposited portion (6a) and the inclined end portion (6b) are crushed by a design forming face (73) of a cooling-press lower mold (70) and the design forming protrusion (82) of the cooling-press upper mold (80), so that they are pressed into desired shapes.

Description

The method of edge treatment of laminate and laminate blank
Technical field
The present invention relates to the method for edge treatment of laminate and laminate blank, for example relate to as the laminated plate material of the interior material of automobile etc. and the method for edge treatment of laminate blank.
Background technology
In automobile, in the past, the interior material of the panel of luggage case or vehicle door interior trim etc. used resin forming product.And in recent years, the feature that further is conceived to resin forming product is " light weight " and " can tackle complicated shape " these two features.
The structure of resin forming product for example exists the hollow structure of high rigidity, the sandwich structure of the high rigidity of light weight etc., selects according to necessary strength or shape, function.
In the past, as the laminate blank of sandwich structure, for example known just like honeycomb core like that in the single or double laminated cover of central layer and the structure that constitutes with longitudinal wall part.This laminate blank is cut to desired profile shape, thus, be used as vehicle with or interior material for building or outer exterior material etc.
But this laminate blank comprises the central layer with longitudinal wall part and thickening when only cutting off the end, can be seen the cut part of end, so may make degraded appearance.Therefore, proposed the terminal laminate (for example patent documentation 1) of handling the outward appearance that improves the end is implemented in the end after cutting off.In this patent documentation 1 disclosed technology, following laminate is disclosed: the end butt that makes hot cutter and laminate blank, on one side laminate blank is heated one side conquassation laminate blank and forms bending part, make it be thermally bonded in the sidepiece of laminate blank to the upside bending this bending part.
