Laminating machines, vacuum laminating equipment, and flat-press laminating equipment are used in this laminating machine.

Abstract

The invention relates to a lamination apparatus capable of preventing the formation of voids in the resulting multilayer and producing multilayers of improved flatness, comprising a vacuum lamination apparatus (1) and a first-press flat lamination apparatus (2). The vacuum lamination device (1) consists of a pair of plate blocks (11 and 12), and the base material (104) and resin (106) are pressed between the plate blocks (11 and 12). The plate block (12) that moves forward and backward consists of a lamination plate (22) and padding material (21), and the padding material (21) has a multilayered structure consisting of not less than three layers which include a fiber layer and a rubber layer. The compressive force on the substrate material (104) and resin (106) between a pair of plate blocks (11 and 12) was set to be between 2.5 and 3.97 MPa per unit area of ​​500 mm².
