Claims10
An apparatus for dry forming cellulose products, comprising:
- a defibrating mill having an inlet section configured to receive a cellulose sheet and an outlet section configured to provide a flow of loose cellulose fibers,
- a forming wheel rotatable about a rotation axis and having an external surface provided with a plurality of discrete forming seats configured for forming cellulose product blanks, and
- a fiber deposition chamber configured to receive said flow of loose cellulose fibers from said outlet section of the defibrating mill and facing a sector of said external surface of the forming wheel for depositing loose cellulose fibers into said plurality of discrete forming seats,
- wherein each discrete forming seat of said plurality of discrete forming seats has a bottom wall recessed relative to said external surface, said bottom wall having variable depth, and
- wherein a central portion of each discrete forming seat has a depth less than a depth of an annular portion surrounding said central portion.

A method for dry forming cellulose products, comprising:
- feeding a cellulose sheet to an inlet section of a defibrating mill and providing a flow of loose cellulose fibers at an outlet section of the defibrating mill,
- providing a forming wheel rotatable about a rotation axis and having an external surface provided with a plurality of discrete forming seats configured for forming cellulose product blanks, and
- sending said flow of loose cellulose fibers from said outlet section of said defibrating mill to a fiber deposition chamber facing a sector of said external surface of the forming wheel and depositing loose cellulose fibers into said plurality of discrete forming seats,
- wherein each discrete forming seat of said plurality of discrete forming seats has a bottom wall recessed relative to said external surface of the forming wheel, said bottom wall having variable depth, and
- wherein a central portion of each discrete forming seat has a depth less than a depth of an annular portion surrounding said central portion.
