Title:
METHOD FOR MANUFACTURING LAMINATE AND APPARATUS THEREFOR
Document Type and Number:
Japanese Patent JP2001078399
Kind Code:
A
Abstract:

To suppress an increase in the thickness of lamination layers and prevent degradation of a magnetic property by applying a low-viscosity adhesive to the side end surface of a laminated single plate, and infiltrating and adhering the adhesive into a gap between the laminated single plates through a capillary phenomenon.

This laminate is formed so that an adhesive inhibitor 2 may be applied between blocks 3 on which a plurality of single plates 1 may be laminated. A low- viscosity adhesive 4 having 3000 CPS viscosity or lower is applied to the side end surface of the laminate. Because the viscosity of the adhesive 4 is low, a capillary phenomenon infiltrates the adhesive 4 between gaps of the single plates 1 to bond the single plates 1, however, a gap between the single plates 1 to which the adhesive inhibitor 2 is applied is not bonded. Fn the low-viscosity adhesive, its viscosity is determined depending on the thickness of the single plate and its surface condition as appropriate. For example, epoxy, hot melt, or silicone cyanoacrylate adhesive is preferable. By applying an adhesive inhibitor, such as oil, to the single plate at prescribed intervals before laminating the single plates, and forming a separated part on the laminate, a laminate may be formed with a fixed number of single plates bonded.
