Title
(EN) METHOD AND APPARATUS FOR LAYING A GRANULAR PATTERN
(FR) PROCEDE ET APPAREIL POUR POSER UN ORNEMENT GRANULAIRE
Abstract
(EN)
A method for laying down a continuous, predetermined pattern of granular material upon a moving substrate (12) includes moving the substrate past at least two stations, each station including a rotating drum (18) with a drum wall (20) defining a limited retention region under vacuum (34) and a plurality of through-apertures (36) arranged in an element of the desired pattern. Granular material (G) applied to the surface of the drum is held by vacuum in the desired pattern. After removal of excess granular material, the vacuum is discontinued causing the granular material to disengage from the drum surface and pass, by force of gravity, onto the surface of the substrate in the form of the predetermined element of the desired predetermined pattern. An apparatus for laying down a continuous, predetermined pattern of granular material upon a moving substrate is also described.
(FR)
Un procédé pour poser un ornement prédéterminé continu de matériau granulaire sur un substrat mobile (12) consiste à faire passer le substrat devant au moins deux postes, chaque poste comportant un tambour rotatif (18) avec une paroi (20) définissant une région de rétention limitée sous vide (34) et une pluralité d'ouvertures de passage (36) disposées dans un élément de la configuration désirée. Le matériau granulaire (G) appliqué à la surface du tambour est maintenu, par le vide, dans la configuration désirée. Après élimination du matériau granulaire en excès, le vide est supprimé, provoquant ainsi le dégagement du matériau granulaire de la surface du tambour et son passage par gravité sur la surface du substrat sous la forme de l'élément prédéterminé de la configuration désirée prédéterminée. Est également décrit un appareil pour poser un ornement prédéterminé continu de matériau granulaire sur un substrat mobile.
