    摘要： Coarsely shredded paper powder is pulverized using a first vertical roller mill equipped with a plurality of first pulverizing rollers 15 to obtain a fine paper powder having an average particle diameter of 50 μm or greater and less than 150 μm. Then, such a fine paper powder is further pulverized using a second vertical roller mill equipped with a plurality of second pulverizing rollers 25 to obtain a fine paper powder having an average particle diameter of 25 μm or greater and less than 50 μm. Concerning the inclination angle θ1 of grooves 15a, 25a with respect to axes L of rotation of said first and second pulverizing rollers, an angle of inclination θ1 of the first pulverizing rollers 15 is smaller than an angle of inclination θ2 of the second pulverizing rollers 25. Accordingly, the fine paper powder can be produced without incurring a substantial environmental impact.

    摘要： The invention relates to a mould system (1) for manufacturing a cardboard-based container, comprising a movable mould half (10) and a stationary mould half (20), which are located opposite to each other, the mould system (1) enabling the manufacture of a container (500) that comprises a bottom (57) pressed from a cardboard blank and walls (59) connected to the bottom, and a rim (50) that is at least partly cast of plastic and connected to the upper edge of the walls, encircling the walls, whereby the mould half (10) that is movable with respect to the stationary mould half (20) includes at least a core plate (4) provided with a core (41), a plate-like seal ring (5), which is movable with respect to the core (41) and comprises a seal surface (5a) and surrounds the core (41), and a collar ring (6), which can be adapted between the core (41) and the seal ring (5) and by which the rim (50) can be made on the container and which can be moved with respect to both the seal ring (5) and the core (41); and the stationary mould half (40) includes at least a mould plate (7) that is provided with a mould cavity (71) and a seal surface (7a). In the mould system (1) according to the invention, an insert (720) can be supported on and detachably attached to the base (71b) of the mould cavity (71) reducing the depth H of the mould cavity by its height h, so that the continuous surface (71b) of the insert (720) works as the new bottom (71b) of the mould cavity and that the length H of the part of the core (41) that penetrates
