Abstract
An apparatus for manufacturing a layered product having a curved surface part with an extremely small radius of curvature while lowering the rate of occurrence a defective product is provided. The manufacturing apparatus is for a layered product in which a decorative material is laminated on a surface and side of a base material, and includes a cutting unit for forming a first cut portion at the corner of the base material and forming a second cut portion having an arc-shaped portion at a portion of a rear surface side of the decorative material opposing to the first cutout part and a bending member for bending the decorative material at the circular arc-like part of the second cutout part.
Claims6
An apparatus for manufacturing a layered product in which a decorative material made of a thermosetting resin is laminated on a surface and a side face of a base material, comprising:
- a conveyer mechanism that conveys said base material and said decorative material in a state that said decorative material is fixed to an upper surface of said base material;
- a cutting unit that forms a first cut portion on a cornering side of said base material to be conveyed by said conveyer mechanism and also forms a second cut portion, which includes an arc-shaped portion, on a rear surface side of said decorative material at a part corresponding to said first cut portion;
- and
- a bending member that bends said decorative material at said arc-shaped portion in said second cut portion;
- wherein said cutting unit comprises a cutting tool which has a cutting blade having a first cutting plane that forms said first cut portion by cutting the cornering side of said base material and a second cutting plane that forms said second cut portion by cutting the rear surface side of said decorative material, and a part of said second cutting plane connected to said first cutting plane is formed to be an arc-shaped plane, and said cutting unit further comprises a first guiding roller which guides a side face of said base material being conveyed by said conveyer mechanism, a second guiding roller which guides an upper surface of said decorative material, a pressing guiding member which is supported by a resilient member and presses and guides a rear surface of a bending margin of said decorative material, and a supporting mechanism that supports said first guiding roller, said second guiding roller, said pressing guiding member, and said cutting tool in a manner that positions thereof can be changed so that a cut depth of said base material is alterable.
A method for manufacturing a layered product in which a decorative material made of a thermosetting resin is laminated on a surface and a side face of a base material,
- the method comprising:
- a cut portion forming step for forming a first cut portion on a cornering side of said base material and also forming a second cut portion, which includes an arc-shaped portion, on a rear surface side of said decorative material at a part that corresponds to said first cut portion;
- and
- a bending step for bending said decorative material at said arc-shaped portion in said second cut portion;
- wherein said cut portion forming step performs cutting of said base material and said decorative material with a cutting tool to form said first cut portion and said second cut portion simultaneously,
- wherein said cut portion forming step and said bending step for bending said decorative material are performed while said base material and said decorative material are being conveyed in a state that said decorative material is fixed to the surface of said base material, and
- wherein said cut portion forming step is a step in which said first cut portion and said second cut portion are formed in a state that an upper surface of said decorative material is guided by a second guiding roller at the same time that a side face of said base material conveyed is guided by a first guiding roller, and a state that a rear surface of a bending margin of said decorative material is pressed and guided with a pressing guiding member supported by a resilient member, and is a step in which guiding positions of said first guiding roller and said second guiding roller with respect to said base material and said decorative material and also a cut depth of said base material are alterable.
