Abstract:
1. A laminated sheet producing apparatus comprising: a multilayer laminating apparatus that forms a first laminate in which a plurality of kinds of sheet materials are laminated in a lamination direction as layers having a layer number more than the number of the plurality of kinds of sheet materials; an edge adding apparatus having a confluence portion which forms a second laminate in which an edge material is added to at least one end portion in a width direction of the first laminate flowing along a flow channel direction as an edge portion; and a die that molds the second laminate into a sheet shape widening the second laminate in the width direction; wherein an area of each region resulting from division of a cross-sectional configuration of each flow channel for the edge material perpendicular to the flow channel direction at the confluence portion by lines for dividing the configuration into 10 equal portions in the lamination direction is defined as Sn (n=1, 2, 3, 4, 5) in the direction from a central portion in the lamination direction toward an end portion in the lamination direction, the relationships of Formula (1) where S1≦S2≦S3≦S4≦S5 and Formula (2) where S1<S5 are simultaneously satisfied.
