Abstract: A device for the separation, lifting and removal of complete flat elements includes an open structure, suited to receive in its lower central part a storage for the metal sheets and two lateral stands, each supporting at its lower end a set of rollers leaning against and guiding the metal sheet to be separated and lifted. Further, one of the lateral stands presents under its set of rollers a template which horizontally displaces the top metal sheet of the pile.The other lateral stand also presents at its lower end the set of rollers and a template, which receives the displaced metal sheet and lifts it from the pile of metal sheets. In one form of execution of the device, each stand is provided with two hydraulic or pneumatic cylinders, one being for the vertical movement and one for the horizontal movement. Another form of execution of the device includes two lateral stands being provided with a single cylinder with a vertical stroke.

Abstract: A punching and shearing machine in which a single hydraulic cylinder (1) operates alternatively the punch or the shear of the machine. When the punch is operative, a manually operated eccentric lever (16) blocks the shear carrying member (8) so that the stem (6) of the piston in the hydraulic cylinder (1) causes motion of the punch carrying member (3). If, on the other hand, the shear is to be operated, another manually operated eccentric lever (14) blocks the punch carrying member (3), so that the external part of the hydraulic cylinder, which is connected to the shear carrying member (8), causes the motion of the shear carrying member only. Safety micro-switches are provided to interrupt the hydraulic circuit controlling the cylinder (1), if the eccentrics (14, 16) are both free or both are blocking a tool carrying member.
