  • Apparatus and method for manufacturing security paper
    Patent number: 8394238
    Abstract: An apparatus for manufacturing security paper, comprising at least one main forming roller, which is provided with a lower portion or forming portion, which is arranged inside a forming box that contains a paper paste, an upper portion or deposition portion, which is arranged below a collecting wire that can move along an advancement direction and is designed to receive, at a collecting face, the sheet formed on the forming roller, and a device for depositing security elements that is arranged upstream of the main forming roller along the advancement direction of the collecting wire and is adapted to deposit the security elements at the collecting face.
    Type: Grant

  • Capacitance controlling process
    Patent number: 7300611
    Abstract: Process for controlling the capacitance value (C1) of a tubular sheath (1) formed by extrusion of an insulation compound (2) on an electrical cable (3) in an extrusion head (4), a foaming agent (FA) being introduced in the insulation compound (2) in such a way as to improve the capacitance value (C1) of the tubular insulation sheath (1), this process being characterised in that: a predetermined amount of foaming agent (200) is used in such a way as to obtain a predetermined capacitance value (C1) for the tubular insulation sheath (1), and in order to control precisely the capacitance value (C1) of the tubular insulation sheath (1), a gas pressure (110) is applied on at least a portion of a face (100, 101) of the insulation compound (2) extruded by the extrusion head is (4), the value of the gas pressure (110) is changed in such a way as to control the capacitance value (C1) of the tubular insulation sheath (1).
