A METHOD OF MAKING A LAMINATED PANEL, COMPRISING THE STEPS OF FORMING AN ASSEMBLY OF LAYERS INCLUDING AN OUTER LAYER HAVING INCORPORATED THEREIN A LATENTLY ADHESIVE BINDER MATERIAL, A CORE LAYER FORMED OF FINELY DIVIDED PARTICLES OF SOLID MATERIAL AND HAVING INCORPORATED THEREIN A LATENTLY ADHESIVE BINDER MATERIAL IN AN AMOUNT LESS THAN THE AMOUNT WHICH SAID CORE LAYER IS CAPABLE OF ABSORBING, AND A SEPARATING LAYER BETWEEN SAID OUTER LAYER AND SAID CORE LAYER, SAID SEPARATING LAYER BEING ADAPTED TO PERMIT DIFFUSION FROM THE OUTER LAYER TOWARD THE CORE LAYER OF A SUFFICIENT AMOUNT OF BINDER MATERIAL FORM SAID OUTER LAYER WHEN SAID BINDER MATERIAL IS PLASTICIZED TO JOIN THE LAYERS TO EACH OTHER WHILE PREVENTING SUBSTANTIALLY MORE THAN SAID SUFFICIENT AMOUNT OF BINDER MATERIAL FROM DIFFUSING FROM SAID OUTER LAYER TO SAID CORE LAYER, WHEREBY A SAVING IN BINDER MATERIAL IS EFFECTED WHILE OBTAINING SECURE JOINING OF SAID LAYERS TO EACH OTHER; AND PRESSING SAID LAYERS TOGETHER UNDER HEAT THEREBY PLASTICIZING SAID BINDER MATERIAL FOR SECURELY JOINING SAID LAVERS TOGETHER,

Claim 3
Dependent Claim
130 words
A LAMINATED PANEL, COMPRISING IN COMBINATION, AN OUTER LAYER HAVING ADHESIVE BINDER MATERIAL INCORPORATED THRERIN; A CORE LAYER FORMED OF LOOSELY ARRANGED FINELY DIVIDED PARTICLES OF SOLID MATERIAL AND HAVING AN ADHESIVE BINDER MATERIAL INCORPORATED THEREIN IN AN AMOUNT LESS THAN THE AMOUNT WHICH SAID CORE LAYER IS CAPABLE OF ABSORBING; AND A SEPARATING LAYER BETWEEN SAID OUTER LAYER AND SAID CORE LAYER, SAID SEPARATING LAYER BEING ADAPTED TO PERMIT DIFFUSION OF AN AMOUNT OF BINDER MATERIAL FROM THE OUTER LAYER TO THE CORE LAYER WHICH IS SUFFICIENT FOR THE OUTER LAYER TO THE CORE LAYER WHICH IS SUFFICIENT FOR JOINING THE LAYERS TO EACH OTHER AND TO PREVENT DIFFUSION OF A SUBSTANTIALLY GREATER AMOUNT OF BINDER MATERIAL THAN LAYERS BEING JOINED TOGETHER BY THE ADHESIVE BINDER MATERIAL INCORPORATED THEREIN.
