A sheet metal bending brake (10) having a frame (12) with a sheet metal support surface (14). A clamping jaw (22) is movable relative to the frame support surface to clamp the sheet metal (26) between the clamping jaw and the frame. The clamping jaw has a linear front edge (32). An elongated bending arm (34) is pivotally mounted to the frame by an elongated flexible strap (50) having spaced apart edges. One edge of the strap is secured to the bending arm while the other edge of the strap is secured to the frame such that the bending arm extends parallel to and closely adjacent the clamping jaw front edge (32).
L'invention concerne une presse plieuse de tôle possédant un cadre pourvu d'une surface de support de tôle. Une mâchoire de fixation peut se déplacer par rapport à la surface du support du cadre de manière à fixer la tôle entre la mâchoire de fixation et le cadre. Cette mâchoire de fixation comporte un bord avant linéaire. Un bras de pliage allongé est monté pivotant au cadre au moyen d'une bande souple allongée qui présente des bords séparés. Un bord de la bande est fixé sur le bras de pliage, tandis que l'autre bord de la bande est fixé sur le cadre, de telle manière que le bras de pliage s'étend parallèlement au bord avant de la mâchoire de fixation et est étroitement adjacent audit bord.
