Abstract: The invention concerns a corrugating roll for producing a corrugated web, having a fluting, from a material web. The corrugating roll has a corrugating roll body, a central longitudinal axis, a peripheral direction about the central longitudinal axis and a surface fluting with at least one first corrugating tooth, which is arranged peripherally on the corrugating roll body, and at least one second corrugating tooth arranged peripherally on the corrugating roll body and which differs from the at least one first corrugating tooth for reducing corrugating roll operation-related vibrations.

Abstract: A corrugating roller, for the manufacture of corrugated cardboard, has a rotation axis and a corrugation. The corrugation has corrugation peaks and corrugation troughs as well as corrugation flanks, which connect the corrugation peaks and the corrugation troughs with each other. The corrugating roller has an air discharge device with an air collection groove, which is open outwardly in a radial direction, runs at least section-wise around the rotation axis, intersects at least some of the corrugation peaks and is limited by a first and a second side wall, which face each other. The air discharge device has an air connection channel, which extends from the side walls of the air collection groove, and an air suction channel, which is in flow connection with the air connection channel and can be subjected to negative pressure.

Abstract: The invention relates to a device for conveying strips of corrugated cardboard, the device comprising a work table for conveying strips on the work table along a direction of conveyance, wherein the work table is supported on a floor and comprises at least one longitudinal groove for accommodating an element which is displaceable therein, and at least one slide which is disposed underneath the work table and is actuable for displacement in the direction of conveyance, which slide comprises an element which is actuable for upward extension through the at least one longitudinal groove for cooperation with the strip.

Abstract: The invention relates to a device for changing the spatial orientation of a corrugated-cardboard strip, the device comprising a supplying device for supplying strips of corrugated cardboard, a turning roller comprising a cylindrical surface, the turning roller being mounted for rotary drive in a direction of rotation, at least one accommodation means disposed on the cylindrical surface of the turning roller for detachably fastening at least one strip on the cylindrical surface, and a stripping device disposed downstream in a direction of rotation for stripping the strips off the cylindrical surface.

Abstract: The invention relates to a machine for producing corrugated honeycomb cardboard, the machine comprising a block supplying device for supplying blocks of corrugated cardboard along a direction of conveyance, a cutting device for cutting strips from a block of corrugated cardboard, a gluing device for applying glue to at least one side of the strips, a corrugated-cardboard-strip turning device for changing the spatial orientation of the strips, and a joining device for adhesively joining the strips together to form corrugated honeycomb cardboard.
