PURPOSE:To enable resin to be laminated continuously, while the point of confluence with the most suitable balance is selected by regulating a slit setting member. CONSTITUTION:The resins B, C, A, C supplied from resin introducing paths 6-10 are guided into manifolds 12-16, and introduced in an independent flow path by a slit setting member 2, whereby said resin reaches respectively flow paths 17-21. The resins C, A, C in the flow paths 18-20 are caused to flow in confluence by the slit setting member 2 and form layers C-A-C, and then they flow into a comfluence path 22. Further, the layers C-A-C in the confluence path 22 are caused to make confluence with the resins B, B in the flow paths 17, 21 by using the slit setting member 2, and form layers B-C-A-C-B which enter a comfluence path 11, whereby the sheet with five layers of three kinds are formed. Since the slit setting member 2 may be regulated so that the flow path is partially opened or fully opened from full closure, the point of confluence with the most suitable balance can be selected. |
