Abstract: The invention relates to a pressure tank comprising a liner which comprises a cylindrical portion and closure caps, a central axis (X) and a pole being defined on the liner, a first plurality of slivers which follow a first rotational direction with respect to the peripheral direction of the liner and a second plurality of slivers which follow a second rotational direction with respect to the peripheral direction of the liner are provided, the first plurality of slivers and the second plurality of slivers overlapping at least in part, and the first rotational direction followed by the first plurality of slivers being opposite the second rotational direction followed by the second plurality of slivers.

Abstract: The present invention relates to a device for gripping a flat structure with openings in the area of its upper side, in particular a honeycomb structure, comprising two gripper units spaced apart from each other in a length direction, each of which in turn comprises at least one pin, and at least one pin displacement unit which is adapted to displace the at least one pin in an extending direction, as well as a tilting unit which is adapted to tilt at least one of the gripper units about a tilting axis extending substantially in a width direction. The invention also relates to a method for gripping a flat structure by means of such a device.

Abstract: Laying die includes an attaching element having an inlet port for receiving positively pressurized gas; and a carrier body made from an elastically deformable material and attached on a lower side of the attaching element. The carrier body includes passages enabling a gas flow between the attaching element and the lower side of the carrier body opposed to the attaching element. The attaching element houses a flow path arranged to receive pressurized gas from the inlet port and a longitudinal pathway extending from the lower side of the attaching element towards an upper side of the attaching element. The flow path discharges into the longitudinal pathway at a junction section, which is arranged such that pressurized gas discharging into the longitudinal pathway creates a negative pressure and comprises a curved deflection surface curved towards the upper side of the attaching element.
