Method and apparatus for working a clad material

An apparatus for working a clad material comprising,

• material supplying means for supplying a trip-like material,
• material feeding means operatively associated with said material supplying means for feeding the material from said material supplying means by a predetermined length,
• metal foil supplying means for supplying a strip-like metal foil,
• metal foil feeding means operatively associated with said meal foil supplying means for feeding a metal foil from said metal foil supplying means by a predetermined length, said metal foil being located above the strip-like material,
• cutting and tacking means for cutting the metal foil transferred by the metal foil feeding means to produce metal foil pieces, said cutting and tacking means placing the metal foil pieces on an upper surface of the material and tacking said metal foils on said upper surface, and
• rolling means situated near the cutting and tacking means for pressure contacting and rolling the tacked metal foil pieces over said material.

A method of boring working reference holes in a strip material having working members thereon, comprising,

• a locating step of setting a position of a reference hole to be bored relative to a position of the working member,
• a reference hole punching step of punching the reference hole in register with the position relative to said working member, and subsequently punching a plurality of the reference holes,
• a hole position measuring step of measuring a distance of an n number of the bored reference holes from one bored reference hole to one working member, n being a natural number,
• a processing step of performing an arithmetic operation on the n number of the measured distance and comparing with a desired distance, and
• a reference hole position adjustment step of modifying and adjusting a boring position with respect to said working member on the basis of the arithmetic operation, and subsequently punching the reference hole at an adjusted position.
