The invention relates to a strip-shaped mould cavity with a structured surface, for producing surfacing materials, especially melamine resin surfaces in the manufacture of laminated plastic sheets. According to the invention, a flexible strip of paper or film is provided with a layer for separating the surfacing material, some slightly cross-linked areas being formed. A three- dimensional mould structure consisting of UV-hardening printing colours is also applied to the separating layer.
L'invention concerne une matrice sous forme de bande pour produire des matériaux de surface, notamment de surfaces en résine de mélamine, lors de la fabrication de panneaux stratifiés, à surface structurée. Selon cette invention, une bande (10) de papier souple ou une pellicule est munie d'une couche (12) la séparant du matériau de surface, ce qui donne lieu à des zones faiblement réticulées sur lesquelles est appliquée une structure de moulage tridimensionnelle d'encres d'imprimerie qui cuisent lorsqu'elle sont exposées aux U.V.
