Abstract (en)
[origin: EP3284587A1] A former of cardboard box corners in assembling machines from a die-cut cardboard sheet (1) provided with tabs (2) folded by means of a folding mechanism in cooperation with a fastening mechanism (3) to define a reinforcement on each corner of the box. The bending mechanism comprises a frame (15) capable of displacing vertically, which is provided with a horizontal beam (15a), both ends of which comprise a bending head (6), which includes a gusset plate (7), for bending the tab (2) of two corners of a same side of the box. The gusset plate (7) is attached to a gear to provide it with an angular bending movement of the tab. This configuration allows for forming the two corners in a single operation of vertical displacement, in an upward/downward direction, of the frame (15) and angular displacement, in a forward/backward direction, of the gusset plate (7).
