The invention relates to a method and an apparatus for the production of a corrugated cardboard product. The apparatus comprises a first one-sided machine and a second one-sided machine which are provided in each case with a press-down belt and with a first and a second grooving roller respectively. The first and the second grooving roller are designed for embossing a wave profile onto a first and a second paper web respectively. The press-down belts serve, together with the respective grooving rollers for connecting the first and the second paper webs in each case to a non-corrugated web for the production of a first and a second single-flute corrugated cardboard web respectively. The first one-sided machine is equipped with a first oblique guide roller the axis of rotation of which is inclined at a vertical inclination angle between side margins of the first paper web.
An apparatus for the production of a corrugated cardboard product, comprising at least one first one-sided machine and one second one-sided machine which are provided in each case with a press-down belt and with a grooving roller, the grooving rollers being designed for embossing a wave profile in each case onto a paper web, and the press-down belt being designed in each case with the grooving rollers for connecting the paper webs in each case to a non-corrugated web to form in each case a single-flute corrugated cardboard web, characterized in that at least the first one-sided machine is equipped with a first oblique guide roller, the axis of rotation of which is inclined at a vertical inclination angle between side margins of a first paper web.
A method for the production of a corrugated cardboard product by means of an apparatus which is equipped with a first one-sided machine having a first web conveying direction and with a second one-sided machine having a second web conveying direction, comprising the steps:
A corrugated cardboard product, comprising a first, second, third and additional non-corrugated web and a first, second and third corrugated web, the first, second and third corrugated web lying in each case between two non-corrugated webs, characterized in that the first corrugated web has a wave profile which is inclined at an offset angle α to side margins of the corrugated cardboard product.
