Abstract
In a manufacturing method, resin in a molten state which becomes a film raw material is caused to hang down from a discharge port of a discharger and the film-like film raw material is continuously discharged, a sheet is conveyed along a sheet pass line, a tip part of the film raw material is formed by cutting and removing an initially formed part of the initially formed film raw material, the tip part is overlapped on the sheet on the sheet pass line, the sheet and the film raw material in a mutually overlapping state are conveyed along the sheet pass line, and the sheet and the film raw material are introduced to a joining part from the sheet pass line.

A manufacturing method for manufacturing a laminate W by laminating a thermoplastic film F on a sheet S1 at a joining part after a pass line forming process of forming a pass line for a film-formed film raw material M, the film raw material M becoming the thermoplastic film F, the pass line forming process comprising:
- a hanging-down step of causing a resin in a molten state to hang down from a discharge port TO of a discharger T, the resin becoming the film raw material M, and the hanging-down step continuously discharging the film raw material M;
- a first conveying step of conveying the sheet S1 along a sheet pass line 1;
- a forming step of forming a tip part E of the film raw material M by cutting and removing an initially formed part M1 of the film raw material M so that the initially formed part M1 is excluded from the tip part E;
- a second conveying step of conveying the sheet S1 and the film raw material M after the tip part E overlaps the sheet S1 on the sheet pass line 1, the second conveying step conveying the sheet S1 and the film raw material M in a mutually overlapping state along the sheet pass line 1;
- and
- an introducing step of introducing the sheet S1 and the film raw material M in the mutually overlapping state to the joining part from the sheet pass line 1.
A manufacturing apparatus for manufacturing a laminate W by laminating a thermoplastic film F on a sheet S1 at a joining part after a pass line forming process of forming a pass line for a film-formed film raw material M, the film raw material M becoming the thermoplastic film F, the manufacturing apparatus comprising:
- a discharger T for causing a resin in a molten state to hang down from a discharge port TO, the resin becoming the film raw material M, and the discharger T continuously discharging the film raw material M;
- a cutter 7 for cutting off an initially formed part M1 of the film raw material M so as to form a tip part E of the film raw material M, the initially formed part M being removed from the tip part E;
- a sheet pass line 1 for receiving the tip part E of the film raw material M with the sheet S1 and conveying the sheet S1 and the film raw material M in a mutually overlapping state after the tip part E overlaps the sheet S1;
- and
- the joining part configured such that the sheet S1 and the film raw material M in the mutually overlapping state are introduced to the joining part from the sheet pass line 1.
