Abstract
An apparatus including a supply source for a long composite which includes a long carrier film and a green ceramic layer continuously formed thereon along its longitudinal direction, a printing station, a drying station and a punching station. A conductor film is printed on the green ceramic layer with conductive paste in the printing station, the printed conductor film is dried in the drying station, and the green ceramic layer provided with the conductor film is punched while being registered with the conductor film and separated from the carrier film in the punching station, whereby a ceramic green sheet for a laminated ceramic electronic component is extracted.
Claims8
An apparatus for manufacturing a ceramic green sheet for a laminated ceramic electronic component, comprising:
- a supply source for supplying a long composite comprising a long carrier film and a green ceramic layer continuously formed thereon along its longitudinal direction, the green ceramic layer having a surface;
- a printing station for printing a conductor film on the surface of said green ceramic layer with conductive paste;
- a drying station for drying said conductor film printed on the surface of said green ceramic layer;
- and
- a punching station for punching said green ceramic layer, after said green ceramic layer passes through said drying station, at a predetermined position with respect to said conductor film, and separating a punched out ceramic green sheet from said carrier film, thereby extracting a ceramic green sheet for a laminated ceramic electronic component;
- wherein said punching station is provided with a head having a contact surface to be in contact with said green ceramic layer, and a cutting edge at the contact surface and structured and arranged to project from said contact surface for punching said green ceramic layer;
- wherein a space within said head is defined by said cutting edge and by said contact surface, and said space has a capacity for receiving and retaining a plurality of stacked ceramic green sheets;
- and further comprising a device for enabling said plurality of stacked ceramic green sheets to be retained in said space, said device comprising a heater associated with said punching station and arranged for heating said ceramic green sheets before they are stacked within said space in said head.
