Abstract

Plieuse, particulièrement pour le pliage de tôles de grandes dimensions, comportant un élément à plier les tôles en forme de latte, relié cinématiquement à un élément à presser les tôles en forme de latte par au moins deux ensembles articulés, chacun desquels est constitué par deux plaques latérales de support, parallèles l'une à l'autre et perpendiculaires à l'axe de basculement de l'élément à plier les tôles, lesdites plaques latérales étant pourvues de fentes rectilignes et hemi-elliptiques, susceptibles d'engager de manière coulissante les pivots d'une bielle située entre lesdites plaques latérales et reliée en charnière audit élément à plier les tôles par une paire de tasseaux disposés parallèlement sur les côtés opposés de la bielle.
