Abstract
Abstract A flat panel-shaped structure with a single face plate reinforced by parallel webs on one side, or with a pair of parallel face plates interconnected by such webs, is formed by removably inserting one or more web-forming profiles in slots of a pressure-resistant supporting plate, these profiles having flange portions coming to rest against opposite surfaces of that plate; two sheets are then placed on the plate surfaces in contact with these flange portions, and the resulting stack is repeatedly passed at elevated temperatures between one or more roller pairs whereby the sheets are laminated under heat and pressure onto the profile or profiles to form two symmetrical panels or a single panel upon removal of the composite from the supporting plate.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
98 words
A method of making a panel-shaped structure, comprising the steps of providing a deformation-resistant supporting plate with a set of parallel slots on at least one major surface, inserting at least one deformable profile with mating web formations into said slots, said web formations being integral with flange portions coming to rest upon said surface, forming a stack by placing a deformable sheet on said surface in contact with said flange portions, laminating said sheet onto said flanges by passing said stack at elevated temperatures between coacting pressure rollers, and removing the resulting laminate from said supporting plate.
Claim 2
Independent Claim
98 words
A method of making a panel-shaped structure, comprising the steps of providing a deformation-resistant supporting plate with a set of parallel slots on at least one major surface, inserting at least one deformable profile with mating web formations into said slots, said web formations being integral with flange portions coming to rest upon said surface, forming a stack by placing a deformable sheet on said surface in contact with said flange portions, laminating said sheet onto said flanges by passing said stack at elevated temperatures between coacting pressure rollers, and removing the resulting laminate from said supporting plate.
Claim 3
Dependent Claim
53 words
A method as defined in claim 1 wherein said supporting plate is provided with another set of slots on the opposite major surface, said stack including a second deformable sheet positioned on said opposite sUrface in contact with other flange portions integral with web formations matingly received in said other set of slots.
Claim 4
Dependent Claim
40 words
A method as defined in claim 2 wherein the slots on opposite surfaces are interconnected, said supporting plate being formed from bars separated by said slots which are laterally withdrawn from between said web formations upon completion of said laminate.
Claim 5
Dependent Claim
17 words
A method as defined in claim 1 wherein said sheet and said profile consist of malleable metals.
Claim 6
Dependent Claim
26 words
A method as defined in claim 4 wherein the metals of said sheet and said profile have different softening points at least along their contact surfaces.
Claim 7
Dependent Claim
19 words
A method as defined in claim 4 wherein at least one of said malleable metals is an aluminum alloy.
Claim 8
Dependent Claim
19 words
A method as defined in claim 6 wherein said elevated temperatures range between substantially 450* C. and 500* C.
Claim 9
Dependent Claim
23 words
A method as defined in claim 1 wherein said slots terminate in widened gaps forming clearances on both sides of said web formations.
Claim 10
Dependent Claim
33 words
A method as defined in claim 8 wherein tapering spacer bars are inserted into said clearances before rolling and are removed after rolling to facilitate extraction of said profile from said supporting plate.
Claim 11
Dependent Claim
33 words
A method as defined in claim 1 wherein a nonbonding antifriction layer is interposed between said major surface on the one hand and said flange portions and said sheet on the other hand.
