Title: Improvements relating to the manufacture of sandwich laminates
IPC: B29C44/12
Filed: 1965-12-08
Abstract: 1,129,658. Laminates. DUNLOP SEMTEX Ltd. 8 Dec., 1965 [10 Dec., 1964], No. 51984/65. Heading B5N. A method of producing sandwich laminates comprising a cellular core, of e.g. polyurethane foam, faced with sheet material, comprises progressively spreading a foam-forming material longitudinally and from side to side over the upper surface of a horizontal facing-sheet commencing at one end thereof; progressively lowering a complementary facing- sheet over and in registration with the portion of the horizontal sheet which has been spread with the foam-forming material; and progressively clamping the lowered portion of the complementary sheet to said horizontal sheet at a spaced distance apart from the latter so as to define a mould cavity to be filled with foam generated by the spread foam-forming material. In a preferred way of performing the method a lower horizontal facing-sheet is placed on a platen, which may be heated, carried by a support. Rails at the longitudinal edges of the support carry a carriage which is driven to move from end to end of the platen, and which carries a distributer for the foam-forming material, the distributer being mounted on a sprocket driven chain for reciprocal movement transversely of the platen. When the horizontal facing-sheet has been placed on the platen, the carriage and distributer are driven to spread foam-forming material progressively over the upper surface of the sheet. The complementary upper facing-sheet is releasably supported above the platen on rods or small rollers carried by hooks. As the carriage moves, tripping-arms thereon dislodge the hooks so that the rods or small rollers fall into a cradle on the carriage and the upper facing-sheet is progressively lowered under gravity into registration with the spread portion of the horizontal sheet, and is progressively clamped at a spaced distance from said sheet by upper platens which are lowered progressively. The upper sheet is also supported during its lowering by a horizontal roller or rollers carried by the carriage. Preferably the facing-sheets are held at the spaced distance by spacing pieces which are either of the same material as the core, or of timber, in which cases the pieces form part of the finished laminate, or are of metal or other material coated or treated with a releasing agent in which case they are removed from the completed laminate. The operation of the various parts of the machine described may be controlled by timing gear.
