Abstract: A device for positioning a metal sheet on a transfer conveyor comprises a support surface for the sheet, guides extending parallel to the conveyor, a carriage slidably supported on the guides, sheet gripping clamps supported on the carriage, reference stops for the longitudinal and transverse positioning of the sheet relative to the conveyor feed direction, jacks for moving the gripping clamps between a position in which they pick up the sheet on the support surface and a position in which they abut against the transverse reference stops, and drive means for the carriage.

Abstract: A device for stepwise feeding a hose for packaging products, in particular fruit and vegetable products comprises a frame, pincer gripping jaws swivel supported by the frame, a first jack for moving the gripping jaws between a raised position and a lowered position and a second jack for operating the gripping jaws to grip the lower closed end of a packaging sleeve when the gripping jaws are in the raised position and drag that end downwards and then release it when the gripping jaws are moved to the lowered position.

Abstract: A blanking and forming press for sheet metal caps having a fixed cross member, a sleeve constituting the blanking knife housed in the fixed cross member, first and second cross members supported mobile relative to the fixed cross member on its opposed sides, a rod connected at its one end to the first cross member and at its other end to a forming and blanking punch, a cylindrical die supported by the second cross member mobile coaxially to the rod and defining a blanking knife cooperating with the knife defined by the sleeve to form, as the mobile cross members approach each other, a cap member by permanent deformation of a discoidal element cut by the sleeve penetrating into the die.
