摘要： The invention relates to a method and an apparatus for deep-drawing a tray (1) from fiber-based sheet material (2), such as polymer coated board. The apparatus comprises a female moulding tool (3), which comprises a cavity (7) for forming the tray bottom outwardly, a male moulding tool (4), which comprises a plunger plate (11) for forming the tray bottom inwardly, the plunger plate being movable with respect to the cavity for forming the tray, and clamps (6, 15) with an interface for holding the sheet material and forming a tray rim flange. According to the invention by laterally distancing at least one of the moulding tools (3, 4) from the sheet material leeway is provided for free forming of the tray side walls while wrinkling or tearing of the same is avoided. Spacer plates (13) may be positioned behind the plunger plate (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) there below, 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.

摘要： The invention relates to a method and apparatus for forming a fiber-based tray by deep-drawing a tray from a fiber-based sheet material.
The method according to the invention comprises:
(i) bringing the sheet material between a female moulding tool, which comprises a cavity for forming the tray bottom outwardly, and a male moulding tool, which comprises a plunger plate for forming the tray bottom inwardly,
(ii) clamping the sheet material along the circumference of the female and male moulding tools, to hold the material during the deep-drawing step,
(iii) moving the plunger plate with respect to the cavity for forming the tray, and
(iv) wherein the moulding tools are arranged so that between the cavity bottom and the clamp interface the male moulding tool is laterally distanced from the sheet material, to avoid the surfaces of the male moulding tool becoming to a snug fit with the sheet material and leave free open space inside of the tray side wall being formed, thus allowing free forming of unwrinkled side walls for the produced deep-drawn tray.
