    Abstract: The invention relates to a method and an apparatus for deep-drawing a tray (1) from a blank of sheet material (2). The blank is provided with score lines, which determine the location of wrinkles formed in the process. The apparatus comprises a female moulding tool (3), which comprises a cavity (7) for forming the tray bot-tom outwardly, a male moulding tool (4), which comprises a plunger (11) for form-ing the tray bottom inwardly, the plunger being movable with respect to the cavity for forming the tray, and clamps (6, 15) with an interface for holding the sheet ma-terial and forming a tray rim flange. According to the invention by laterally distanc-ing at least one of the moulding tools (3, 4) from the sheet material leeway is pro-vided for free forming so that wrinkling of the tray side walls is achieved in a con-trolled manner. Spacer plates (13) may be positioned behind the plunger (11), to adjust its position in relation to the cavity (7) of the female moulding tool (3). The cavity may have a separate bottom plate (8) and spacer plates (9) therebelow, or screw means may be provided for adjusting the distance of the bottom of the cavi-ty from the clamp interface and thereby varying the depth of the tray.

    Abstract: A deep-drawn paper tray made of paper material, a method and an apparatus for manufacturing the tray, and a closed product package comprising the tray. The tray having a bottom and upwardly expanding side walls around the bottom, the side walls of the tray being shaped to expand through a plurality of circumferential steps dimensioned low enough for obtaining wrinkle-free side walls for the tray. The outermost step is a flat, wrinkle-free rim flange, which enables liquid and gas proof heat-sealing of a lid to form the package. The apparatus may comprise upper and lower moulding tools with concentric movable frames for forming the tray bottom and side wall steps from paper blanks, and moulding tools may be mounted onto a rotating turret carrying a paper blank through working stations arranged along the turret circumference, to shape the tray bottom and the side wall steps at the consecutive stations.

    Abstract: The present invention relates to a method of deoxygenating tall oil pitch, yielding aliphatic and aromatic hydrocarbons. The invention even comprises turning the aliphates into polymerizable olefins by steam cracking, and turning the aromates into polymerizable terephthalic acid by oxygenation and, as necessary, rearrangement. The monomers can be used for the production of polymers of partially or completely biologic origin. According to the invention, tall oil pitch is first heated to turn it into liquid, which is then fed into a catalyst bed and catalytically deoxygenated with hydrogen. The deoxygenation catalyst is preferably a Ni—Mo catalyst and, in addition, a cracking catalyst can be used, such as an acidic zeolite catalyst. The deoxygenated product stream is cooled down so as to obtain a liquid, which is distilled for separation of the aliphatic and aromatic hydrocarbons for use in the production of the respective monomers and finally polymers.

According to the invention by laterally distancing at least one of the moulding tools (3, 4) from the sheet material leeway is pro-vided for free forming so that wrinkling of the tray side walls is achieved in a controlled manner. Spacer plates (13) may be positioned behind the plunger (11), to adjust its position in relation to the cavity (7) of the female moulding tool (3). The cavity may have a separate bottom plate (8) and spacer plates (9) therebelow, or screw means may be provided for adjusting the distance of the bottom of the cavity from the clamp interface and thereby varying the depth of the tray.
