Abstract

L'invention concerne un dispositif (10) destiné à lisser une couche de matière (11) formée d'une matière de remplissage, telle que chape, béton ou analogue. La couche de matière (11) est appliquée sur une base (12). Un outil à lisser (14) présente deux unités d'ajustement (25) qui prennent appui, via leurs surfaces d'appui respectives (46), sur la base (12). Chaque unité d'ajustement (25) présente un actionneur (27), par l'intermédiaire duquel la distance au pied, entre l'appui (46) et un bord de lissage (15), peut être modifiée. Pendant le lissage, le bord de lissage (15) se déplace au-dessus de la surface (13) de la couche de matière (11). Chaque unité d'ajustement (25) présente en outre un récepteur (26). Via un émetteur (29), un signal (S), de préférence un signal lumineux, est émis dans un plan de référence (E). Les récepteurs (26) des unités d'ajustement (25) se trouvent constamment dans la zone du plan de référence, de sorte qu'ils peuvent recevoir le signal lumineux (S). En fonction du signal de sortie (AI), (A2) du récepteur (26), la distance au pied (Z) de l'élément de pied associé (28), est adaptée de telle façon que le signal lumineux (S) se situe dans le plan de référence (E), à l'intérieur de la zone de tolérance du récepteur (26).
