The method is for making a parallelepiped container from a flat sheet. Folding and unfolding takes place in a synchronous movement. Unfolding contains a phase in which the flaps forming the base or cover are fed perpendicular to the transverse thrust direction (D). For unfolding, a bent face is gripped by suction, opposite to another bent face. Simultaneous adjustment is made of all the container cells. The machine uses stock material, moves the bent and unbent sheets and forms the container in synchronised movements. |
