摘要:
A liquid flow converging device and a method of manufacturing a multi-layer film. The converging device comprises an element (A) having a large number of slits for passing two liquid flows to be converged therethrough and an element (B) having a first converging part for converging, in a laminar form, a large number of laminar liquid flows formed by passing the liquid flows through the large number of slits to form a first laminar liquid flow. The converging device for the liquid flow comprises a first confluence forming device having two or more elements (A) installed independently of each other and two or more elements (B) installed independently of each other.
摘要:
An apparatus is provided for manufacturing a laminated sheet wherein different molten resins are alternately laminated by providing a multitude of slits arranged at intervals and permitting the different molten resins to flow out from the adjacent slits. A value of a shortest flow path length (L1) to a longest flow path length (L2) of the molten resin that flows from an inlet to an outlet of the slit, which is a ratio of (L1) / (L2), is 0.5 or more. The slits include slits having different slit lengths. A flow quantity of the molten resin at the slit is changed by changing the intervals of the slits, length of the slits or by changing the temperature of the molten resin at the slits.
