Abstract
A manufacturing method including a first conveying step of conveying the sheet in a lateral or oblique lateral direction along a sheet pass line below the discharge port; a receiving step of receiving a tip part of the film raw material with the sheet on the sheet pass line, the tip part being discharged and hanging down from the discharge port; a second conveying step of conveying the sheet and the film raw material after the tip part overlaps the sheet on the sheet pass line, the second conveying step conveying the sheet and the film raw material in a mutually overlapping state along the sheet pass line; and an introducing step of introducing the sheet and the film raw material in the mutually overlapping state to the joining part from the sheet pass line.
Claims14
A manufacturing apparatus for manufacturing a laminate by laminating a thermoplastic film on a sheet at a joining part after a pass line forming process of forming a pass line for a film-formed film raw material, the film raw material becoming the thermoplastic film upon cooling the film raw material, the manufacturing apparatus comprising:
- a discharger for causing a resin in a molten state to hang down from a discharge port, the resin becoming the film raw material, and the discharger continuously discharging the film raw material;
- a sheet pass line for conveying the sheet in a lateral or oblique lateral direction below the discharge port, the sheet pass line receiving a tip part of the film raw material with the sheet, the tip part being discharged and hanging down from the discharge port, and the sheet pass line conveying the sheet and the film raw material in a mutually overlapping state after the tip part overlaps the sheet;
- the joining part configured such that the sheet and the film raw material in the mutually overlapping state are introduced to the joining part from the sheet pass line;
- and
- a first cooling roll configured to cool the film raw material, causing the film raw material to become the thermoplastic film, after the sheet and the film raw material in the mutually overlapping state are introduced to the joining part from the sheet pass line, the film raw material hanging down from the discharge port and being wound on an outer peripheral surface of the first cooling roll;
- wherein the thermoplastic film is an elastomer film and the film raw material is a film-formed pre-elastomer.
