Abstract
A bottle forming unit and method for dry-forming a cellulose bottle from an air-formed cellulose blank structure in a bottle forming unit. The dry-formed cellulose bottle comprises a neck portion, a closed bottom portion, and a mid-portion arranged between the closed bottom portion and the neck portion. The mid-portion is arranged in fluid communication with the neck portion. The dry-formed cellulose blank structure is shaped into a shaped cellulose blank structure, where the shaped cellulose blank structure has a tube-like configuration with an inner surface and an outer surface. A first section of the shaped cellulose blank structure is fed to a first forming mould and a semi-closed bottom portion of the cellulose bottle is formed from the first section in the first forming mould, simultaneously with forming the neck portion of a directly preceding cellulose bottle from the first section in the first forming mould. A following second section of the shaped cellulose blank structure is fed to the first forming mould and the neck portion of the cellulose bottle is formed from the second section in the first forming mould, simultaneously with forming a semi-closed bottom portion of a directly following cellulose bottle from the second section in the first forming mould.
