Laminated structure and method of making the same
Abstract
Abstract A LAMINATED STRUCTURE IS FORMED BY BONDING TO A CARRIER, FOR INSTANCE A TEXTILE SHEET, A PRE-FORMED, SHAPE-RETAINING, INTERMEDIATE LAYER OF FILM; THE CARRIER FACE BEING FORMED WITH PROJECTING AND RECESSED PORTIONS AND THE INTERMEDIATE LAYER BEING BONDED TO THE CARRIER IN SUCH A MANNER AS TO CONTACT SUBSTANTIALLY ONLY THE PROJECTING PORTIONS OF THE LATTER. ON THE FREE FACE OF THE INTERMEDIATE LAYER IS THEN FORMED A LAYER OF HARDENABLE MATERIAL IN FLOWABLE CONDITION, WHICH LAYER MUST BE FUSIBLE TO THE INTERMEDIATE LAYER AND MAY CONTAIN A BLOWING AGENT. THE HARDENABLE LAYER IS THEN HARDENED (AND SIMULTANEOUSLY FUSED TO THE INTERMEDIATE LAYER AND ALSO SIMULTANEOUSLY BLOWN IF A BLOWING AGENT IS PRESENT). THEREBY A LAMINATED STRUCTURE IS FORMED SUBSTANTIALLY WITHOUT FILLING THE RECESSED PORTIONS OF THE CARRIER FACE DUE TO THE INTERPOSITION OF THE PREFORMED INTERMEDIATE FILM OR THE LIKE.
