A method for producing continuously a design material in particulate form in a estructuramultilaminar (300), comprising the steps deproporcionar - a material (310) in particulate form - a device (440) transfer to receive said material (300) as particles in a regiónreceptora (442) and transfer to a region (448) of discharge, - said device (440) transfer comprising a first means (452 ) training design, - at least one flat web material as carrier material (320) and / or covering material (330) - means (470) of the carrier endless support for said carrier material (320) having desoporte a design corresponding to the design of said first forming means design of said device (440) transfer - means (472) for containing the carrier material for temporarily securing said carrier material (320) to lasuperficie of said medium (470) of the carrier support, - means (495) for fixing the multilaminate to combine the sandwich structure (300 ), running lasetapas process - transferring said material (310) in particulate form to said receiving region (442) of said device (440) transfer, wherein said first forming means design defines a design departículas group - moving said material design in particulate form to the region (448) of said discharge device (440) transfer - guiding said carrier material (320) on said medium (470) of the carrier support to a delportador speed corresponding to the speed of the carrier support, - deforming said carrier material (320) by said means (472) for containing the carrier material , demanera a slit (328) is formed in the regions unsupported of said carrier material (320), thereby forming a corresponding design to that group of particles design - ejecting said material (310) as particles of said transfer device to said materialportador (320), - depositing said material (310) as ejected onto said carrier material (320) deformed particles, - applying said material (330 ) cover to said carrier material (320) and said material (319) in departículas form p
