Roof module and method of producing a roof module

Abstract

A roof module comprises an outer shell and a foamed inner shell. The outer shell has a rim including an edge of cut and the inner shell extends as far as on the edge of cut. There is also proposed a method of producing such a roof module.

1 . A roof module comprising an outer shell and a foamed inner shell, said outer shell having a rim including an edge of cut and said inner shell extending as far as on said edge of cut.  
     
     
         2 . The roof module according to  claim 1 , wherein said inner shell extends away from said edge of cut in an extension of an outer surface of said outer shell.  
     
     
         3 . The roof module according to  claim 1 , wherein said outer shell is configured with an undercut at its rim.  
     
     
         4 . A method of producing a roof module comprising an outer shell and a foamed inner shell by means of the following steps: 
 an outer shell having a rim is made available;    said rims of said outer shell are cut to size;    said outer shell is placed in a foaming tool;    a curable material is applied onto said outer shell;    said foaming tool is closed, a seal in said foaming tool pressing against said rim of said outer shell from outside towards inside;    said curable material hardens, it reaching said edges of cut on said rim of said outer shell.    
     
     
         5 . The method according to  claim 4 , wherein said seal is pressed elastically against said outer shell when said foaming tool is being closed.  
     
     
         6 . The method according to  claim 5 , wherein said seal plastically deforms said outer shell when said foaming tool is being closed.
