Patent number: 11970823Abstract: A process for forming a pre-form for a moulded pulp fibre product involves providing a porous mould that has one or more pre-form mould portions that each have an outer surface corresponding to a surface of the pre-form. Pulp fibre slurry is discharged from an outlet; each pre-form mould portion is coated with discharged pulp fibre slurry by moving the porous mould relative to the outlet. Thus, a slurry deposit for the pre-form is formed on the outer surfaces of the pre-form mould portions. Fluid from the slurry deposit is extracted through the porous mould to form the pre-form.Type: GrantFiled: January 23, 2020Date of Patent: April 30, 2024Assignee: VARDEN PROCESS PTY LTDInventors: Mark Appleford, Stuart Gordon

Publication number: 20230365322Abstract: In one example, a process for manufacture of a pulp-based dispensing capsule is disclosed. The process includes providing one or more mesh tool sets that are each contoured to one or more preform shapes of the dispensing capsule. Note that each preform shape is a partially shaped version of a final form shape of the pulp-based dispensing capsule. The process also includes providing a holding tank containing a suspension that includes water and pulp fibres; and arranging the mesh tool sets to allow immersion into and withdrawal of the mesh tool sets from the suspension. The process also includes applying a vacuum to the mesh tool sets so as to draw pulp fibres from the suspension onto the mesh tool sets while immersed in the suspension to form a preform pulp fibre mat; and in a second toolset, deforming each preform shape in the preform pulp fibre mat towards the final form shape by the application of pressure.Type: ApplicationFiled: May 1, 2023Publication date: November 16, 2023Applicant: Varden Process Pty LtdInventors: Mark Appleford, Stuart Gordon
