Abstract
Official abstract text for this publication.
The present invention provides a duct molding method by which it is possible to improve the adhesion of a sheet. In the duct molding method of the present invention, a molten thermoplastic resin sheet is positioned between molds. Subsequently, the thermoplastic resin sheet (P) is absorbed onto cavity surfaces of the molds and the molds are closed. Thereby, a duct is molded.
First claim
Opening claim text (preview).
What is claimed is: 1. A duct molding method, comprising: providing molds having cavity surfaces; positioning a pair of molten thermoplastic resin sheets between the molds, including extruding the molten thermoplastic resin sheets, by adjusting a thickness of the molten thermoplastic resin sheets by sandwiching and expanding the thermoplastic resin sheets by a pair of rollers and forwarding downward the thermoplastic resin sheets by rotating the rollers; bonding the thermoplas…
