Abstract: 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.
Abstract translation: 本发明涉及一种用于从诸如聚合物涂覆板之类的基于纤维的片材（2）深拉拉托盘（1）的方法和设备。 该装置包括：一个阴模制工具（3），它包括一个用于向外形成托盘底部的空腔（7）;一个阳模制工具（4），其包括用于向内形成托盘底部的柱塞板（11） 板可相对于用于形成托盘的空腔移动，夹具（6,15）具有用于保持片材并形成托盘轮辋凸缘的接口。 根据本发明，通过侧向地使至少一个模制工具（3,4）与片材材料之间的空间偏离而设置用于自由地形成托盘侧壁，同时避免折皱或撕裂。 间隔板（13）可以位于柱塞板（11）后面，以调整其相对于阴模制工具（3）的空腔（7）的位置。 空腔可以在其下方具有单独的底板（8）和隔板（9），或者可以设置螺纹装置用于调节空腔底部距离夹具界面的距离并由此改变托盘的深度。

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: The invention relates to a method of providing board containers (V) with prints and a printing machine that applies the method. According to the invention, the printing machine comprises a turret head (2), with uniformly spaced radial arms (3) diverging from its rotational axis, each arm ending in a mandrel (4) that carries a container (1); and stationary stations (5, 6, 8) that are located on the path of the turret head for gripping a container, printing it by a printhead (7, 13), and removing the printed container (V). At the printing station (6), the container (1) is digital-printed by the printhead (7), past which the surface of the container is conveyed by means of a rotational motion. The container can be a conical drinking cup (1), which is ink-jet printed by the stationary printhead (7) by rotating the cup by 360° by means of the mandrel (4) that is pushed inside the cup. The cups (1) can be produced at a plant in mass-scale production runs and divided into smaller lots, which are delivered to customers and which the customers then print according to their own individual needs.
