Estimating the term…
The present invention relates to an apparatus for producing a comb-like capacitor element member including a guide member and a plurality of rectangular metal foil pieces bonded to the guide member, comprising an automatic feed mechanism for feeding tape-like foil by a constant lenght toward the guide member, a bonding mechanism for bonding the metal foil to the guide member, and a cutting mechanism for cutting the bonded metal foil. According to the apparatus of the present invention, a comb-like capacitor element member having a plurality of rectangular metal foil pieces bonded can be produced efficiently, by bonding the elongated tape-like metal foil without damaging it.
An apparatus for producing a capacitor element member to be used in production of monolayer capacitor elements, characterized by comprising an automatic feed mechanism for feeding metal foil by a constant length toward a guide member, a mechanism for bonding the metal foil to the guide member, and a mechanism for cutting the bonded metal foil.
An apparatus for feeding metal foil automatically used in production of a monolayer capacitor element, characterized by comprising a constant-length feed mechanism, which in turn comprises at least a pair of pinch rollers for feeding tape-like metal foil while pinching the metal foil;
An apparatus for cutting metal foil, characterized by comprising vertically movable first and second cutting blades for shearing metal foil, the first cutting blade being supported via a shaft and pushed toward the second cutting blade by means of elastic force;
A method for cutting metal foil used in production of a monolayer capacitor element by shearing the metal foil through a scissorlike action, characterized in that, after cutting, a clearance is formed between cutting blades, which are then retracted while the clearance is maintained.
