Pulp mold

A pulp mold includes a mold main body extending along a longitudinal axis and having an inner surface that defines a chamber, an outer surface opposite to the inner surface, and a plurality of channel grooves extending inwardly from the outer surface toward the inner surface and extending along a length of the outer surface. The chamber is divided into a plurality of chamber sections decreasing in diameters gradually and upwardly from the opening along the longitudinal axis. Each channel groove does not communicate with the chamber. A plurality of air holes extend from the outer surface to the inner surface, pass through the channel grooves, and communicate the chamber with the outside.

20220288888 · 2022-09-15 ·

A moulded pulp fibre product and a method of forming a moulded pulp fibre product are provided. The method involves forming two or more pulp fibre pre-forms that each include at least one mating surface. Each pre-form is made from a suspension of pulp fibres in liquid. The pulp fibre pre-forms are assembled into a set in which adjacent pulp fibre pre-forms have mating surfaces that are in contact with, or adjacent to one another. The set of pulp fibre pre-forms are then bonded to form a pulp fibre laminate.

A PICK-UP PRESS DEVICE AND METHOD OF PRODUCING A 3D-MOLDED PRODUCT FROM A PULP SLURRY
20220081846 · 2022-03-17 ·

The document relates to a pick-up press device for use in a process of producing a 3D molded product from a pulp slurry comprising a pick-up press tool presenting a porous first product face; a press tool presenting a second product face; and a vacuum source, connected to the pick-up press tool. The pick-up press tool and the press tool are vertically movable relative one another, wherein, in a first relative position of the press tools, at least one of the product faces is positioned so as to receive a pulp slurry layer in liquid form to its product face, and wherein in a second relative position of the press tools, the product faces are pressed towards each other for pressing the pulp slurry layer. The device further comprises a first transfer tool, wherein the first transfer tool comprises a first forming surface portion, configured to conform to a first portion of the porous first product face, such that a forming gap is defined there between, said forming gap defining a desired pulp slurry layer thickness; and a second forming surface portion, configured to diverge from a second portion of the porous first product face, such that a non-forming space is defined by the second forming surface portion and a second portion of the porous first product face, said non-forming space having a greater thickness than the forming gap.

DEVICE AND METHOD FOR PRODUCING A 3D MOLDED PULP PRODUCT
20220081847 · 2022-03-17 ·

The document relates to a device for producing a 3D molded product from a pulp slurry, comprising a pair of cooperating press tools, each having a respective product face. The press tools are movable relative each other between a closed press position, wherein the product faces are sufficiently close to press the pulp product there between, and an open transfer position, wherein the pulp product can be removed from the product face of one of the press tools.
