Abstract
Abstract A roof headliner having a substrate (10) of corrugated fibreboard, a facing laminate itself having a face layer (12) of fabric and a layer of open cell soft resilient foam (13), and an intermediate layer of relatively stiff semi-rigid foam (15) sandwiched between the substrate (10) and the soft resilient foam (13), and adhering the substrate (10) to the facing laminate.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
56 words
A roof headliner comprising a substrate of corrugated fibreboard, a facing tri-laminate itself having a face layer of fabric, a layer of soft resilient foam, and an impervious backing film, and an intermediate layer of relatively stiff semirigid foam sandwiched between the substrate and the soft resilient foam, and adhering the substrate to the facing laminate.
Claim 2
Dependent Claim
56 words
A roof headliner comprising a substrate of corrugated fibreboard, a facing tri-laminate itself having a face layer of fabric, a layer of soft resilient foam, and an impervious backing film, and an intermediate layer of relatively stiff semirigid foam sandwiched between the substrate and the soft resilient foam, and adhering the substrate to the facing laminate.
Claim 3
Dependent Claim
49 words
A roof headliner according to claim 1 wherein the facing laminate comprises a face layer of velour, a layer of open cell soft resilient foam, and a polyurethane film, said intermediate layer of relatively stiff semirigid foam being foam polyurethane adhered to the fibreboard and to the polyurethane film.
Claim 4
Dependent Claim
31 words
A roof headliner according to either claim 1 or claim 2 further comprising a layer of fibreglass reinforcing fibres contiguous with the substrate and embodied within the relatively stiff semirigid foam.
Claim 5
Independent Claim
123 words
A method of manufacture of a roof headliner comprising: (a) securing the periphery of a tri-laminate sheet having a face layer of fabric, an intermediate layer of open cell soft resilient foam, and a backing layer of polyurethane film, to an open frame, and attaching the frame to a male die of a press, (b) positioning a corrugated fibreboard sheet in a female die of the press which is of shape complementary to the shape of said male die, (c) applying foam forming chemicals to one of said sheets, locating one of said dies above the other, and closing said dies together, (d) retaining the dies closed during foaming of said chemicals, and (e) opening the dies and removing the thereby moulded headliner.
Claim 6
Independent Claim
123 words
A method of manufacture of a roof headliner comprising: (a) securing the periphery of a tri-laminate sheet having a face layer of fabric, an intermediate layer of open cell soft resilient foam, and a backing layer of polyurethane film, to an open frame, and attaching the frame to a male die of a press, (b) positioning a corrugated fibreboard sheet in a female die of the press which is of shape complementary to the shape of said male die, (c) applying foam forming chemicals to one of said sheets, locating one of said dies above the other, and closing said dies together, (d) retaining the dies closed during foaming of said chemicals, and (e) opening the dies and removing the thereby moulded headliner.
Claim 7
Dependent Claim
103 words
A method according to claim 4 wherein the male die is the upper die of a die set and attached to the press, and the female die is a lower die of the die set movable from a loading station into the press, to lie beneath the upper die, further comprising positioning a layer of glass reinforcing fibres over the corrugated fibreboard sheet and applying the foam forming chemicals to the fibreboard sheet through those glass reinforcing fibres while the lower die is at its loading station, moving the lower die into the press, and closing the dies by action of the press.
Claim 8
Dependent Claim
63 words
A method according to claim 5 wherein the roof headliner embodies inserts, the method further comprising laying the inserts in the lower die and abutting the sheets of fibreboard and glass reinforcing fibres against the inserts, before applying the foam forming chemicals, said application of foam forming chemicals being in sufficient quantity to bond together the fibreboard, inserts, glass fibres and tri-laminate sheet.
Claim 9
Dependent Claim
22 words
A method according to claim 5 further comprising trimming the peripheral edge of the head liner after its removal from the dies.
Claim 10
Dependent Claim
82 words
A method according to claim 5 or claim 6 further comprising positioning the headliner fabric side down over a contoured support after its removal from the dies, and piercing the fibreboard substrate, the layer of glass, the foamed chemicals, the polyurethane film backing and the intermediate layer of open cell soft resilient foam of the tri-laminate sheet, but not the fabric, to form a plurality of apertures extending from the fabric through the remainder of the headliner and opening behind the substrate.
