Claims (11)

  In a method for producing a laminate having a metal foil on one side or both sides of a resin film, after laminating the film and the metal foil and winding it around a roll core, the laminate roll is heated. In addition, at least a winding start end of the laminated body in the roll is heat-treated in a state where it does not receive contact pressure from the outer laminated body surface and the core surface.   The method for producing a laminate according to claim 1, wherein the state in which the contact pressure is not received is performed by unwinding and developing the roll.   The method for producing a laminate according to claim 1, wherein the state of not receiving the contact pressure is performed by changing the outer diameter of the core after winding the roll.   The winding core has a cylindrical shape, has a slit in the axial direction of the outer peripheral wall of the winding core, and has an opening width within 5% of the outer peripheral length. 4. The method for manufacturing a laminate according to claim 3, wherein the outer diameter of the core is reduced by changing the width.   A variable device for the opening width of the slit is provided on the winding core, and the variable device is provided at a first engagement member provided on an outer wall at one end between the slits, and at the other end between the slits. The slit is opened by adjusting the engagement relationship between the first engagement member and the second engagement member. The manufacturing method of the laminated body of Claim 4 which changes a width | variety.   Heat treatment is performed in a state in which the laminated body other than the winding start end is not subjected to contact pressure, and the wound laminated bodies in the roll are separated from each other by 5 μm or more. The manufacturing method of the laminated body as described in any one term.   The winding laminate roll is subjected to heat treatment while transporting the transportable laminate formed by thermocompression bonding the film and the metal foil in the first step, and then the metal winding core. The method for producing a laminate according to any one of claims 1 to 6, wherein the laminate is wound into a roll.   The said resin film is a liquid crystal polymer film, The temperature in the said heat processing is 30 degreeC or more lower than the melting | fusing point of this film, and is 10 degrees C or less higher than the same melting point, The claim in any one of Claims 1-7 The manufacturing method of the laminated body of description. The said heat processing WHEREIN: The heat processing time hold | maintained at the temperature after reaching the said heat processing temperature is the range for 60 minutes-240 minutes, The manufacturing method of the laminated body of Claim 8.   The manufacturing method of the laminated body in any one of Claims 1-9 which perform the said heat processing in inert gas atmosphere.   The said film is a thermotropic liquid crystal polymer, The manufacturing method of the laminated body in any one of Claims 1-10.
