Joint construction in a laminate of metal and plastic layer

Abstract

A joint construction in a laminate of, alternately, at least two metal layers and at least one plastic layer accommodated between them comprises metal layers which each have at least two sections. The two sections of at least one outer metal layer overlap one another and are fixed to one another at the location of the overlap by an adhesive. Each metal layer has overlapping sections which are fixed to one another by an adhesive.

1 . Joint construction in a laminate of, alternately, at least two metal layers ( 1 - 3 ) and at least one plastic layer ( 6 ,  7 ) incorporated between them, which metal layers ( 1 - 3 ) each comprise at least two sections ( 4 ′,  5 ′;  4 ″,  5 ″;  4 ′″,  5 ′″) and the two sections ( 4 ′,  5 ′) of at least one outer metal layer ( 1 ) overlap one another ( 8 - 10 ), which two sections ( 4 ′,  5 ′) are fixed to one another at the location of the overlap ( 8 ) by means of an adhesive ( 6 ), characterised in that each metal layer ( 1 - 3 ) has overlapping sections ( 4 ′,  5 ′;  4 ″,  5 ″;  4 ′″,  5 ′″) which are fixed to one another by means of an adhesive ( 6 ).  
     
     
         2 . Construction according to  claim 1 , wherein the overlap ( 8 ) between two sections ( 4 ′,  5 ′) of a metal layer ( 1 ) is offset with respect to the overlap ( 9 ,  10 ) between two sections ( 4 ″,  5 ″;  4 ′″,  5 ′″) of another metal layer ( 2 ,  3 ).  
     
     
         3 . Construction according to  claim 1  or  2 , wherein, in each metal layer ( 1 ,  3 ), one section ( 5 ′,  5 ″,  5 ′″) is straight and the other section ( 4 ′,  4 ″,  4 ′″) is joggled.  
     
     
         4 . Construction according to  claim 1 ,  2  or  3 , wherein each plastic layer ( 7 ,  8 ) is joggled at the location of an overlap ( 8 ,  10 ).  
     
     
         5 . Construction according to  claim 1 ,  2 ,  3  or  4 , wherein each plastic layer ( 7 ,  8 ) is continuous at the location of an overlap ( 8 ,  10 ).
