Abstract: PURPOSE:To correct the dimensional difference between layers or curl by bringing the larger dimensional layer or the outer layer being curled of a flexible metal plastic laminating sheet into slide contact under the tension with the contact part of a rotatable blade being below 0.5mm in its radius of curvature. CONSTITUTION:In the case of the correcting the dimensional difference between layers or the outer layer being curled of a flexible metal plastic laminating sheet (FMCL) 3, the larger dimensional layer or the outer layer being curled of FMCL 3 is made to slide in bringing into contact with a blade 1 while adding a predetermined tension. Inasmuch as, in this case, friction produces between the blade 1 and FMCL 3, a large tension is required, and as the friction is large, it may result in producing the plastic deformation of extension in a metallic foil layer. And the contact part 2 of the blade 1 is made to be rotatable at the radius of curvature of being below 0.5mm, and FMCL 3 is brought into contact therewith at the angle of +80--80 deg.. In this manner, the dimensional difference between layers or curl of SMCL can easily be corrected while preventing the plastic deformation of extension of the metallic foil layer.

Abstract: PURPOSE:To permit the easy correction of a dimensional difference between a metallic layer and a plastic layer, by a method wherein the flexural rigidity of the metallic layer is made smaller than a specified value while the bending rigidity of the plastic layer is made larger than the specified value of the flexural rigidity of the metallic layer. CONSTITUTION:When a laminated plate is to be passed through the end of a bar while bending and contacting the metallic layer side with the end of the bar having the curved surface on the end, which is provided with the radius of curvature smaller than 0.5mm, a compressive stress is exerted on the whole of the metallic layer due to a balance in flexural rigidity of the metallic layer and the plastic layer when the flexural rigidity of the metallic layer is less than 20g/cm and the flexural rigidity of the plastic layer is larger than 1/500 of the flexural rigidity of said metallic layer, therefore, a compressive plastic deformation is generat ed whereby the value of the compressive plastic deformation can be made higher thin 0.4%. On the other hand, almost all of a tensile stress, exterted on the plastic layer, causes only an elastic deformation, therefore, the dimension of the plastic layer is not changed. As an integrated result, only the compressive plastic deformation of the metallic layer remains in a FMCL, processed already, as the shrinkage of higher than 0.4%, therefore, a dimensional difference between the metallic layer and the plastic layer is reduced to 0.1% or less and the dimensional difference may be removed substantially and essentially.

Abstract: PURPOSE:To correct interlaminar dimensional difference, by allowing a long flexible metal foil laminated plate curled in such a state that a metal foil having a thin polymer film is turned to the inside to slide on the curved surface of a specific bar under tension in the longitudinal direction so as to turn the polymer film to the inside. CONSTITUTION:A long flexible metal foil laminated plate (FMCL), wherein a thin polymer film is provided on a metal foil, curled in such a state that the metal foil is turned to the inside is allowed to slide on the curved surface of a bar provided at an angle of 0-80 deg. with respect to the axial direction thereof under tension in such a state that the polymer film is turned to the inside. Further, the FMCL is allowed to slide on the curved surface of the bar provided at an angle of 0--80 deg.C with respect to the lateral direction of the FMCL under tension in the longitudinal direction in such a state that the polymer film is turned to the inside. One of these processes is performed once or more or both of them are performed in arbitrary order once or more to correct the curling of the FMCL.
