Introduction

Karl-Hugo Andersson is a notable inventor based in Vaxjo, Sweden. He has made significant contributions to the field of paper machine technology, holding a total of three patents. His work focuses on improving the efficiency and effectiveness of drying processes in paper production.

Latest Patents

One of his latest patents is titled "Arrangement in Cylinder Dryer." This invention relates to an arrangement in cylinder drying, intended for incorporation in a paper machine. It includes a plurality of heated cylinders arranged substantially parallel in two rows, around which the paper web is taken serpentine during drying. The web is carried by an endless porous fourdrinier wire, which presses the web against the cylinder surfaces in one row of cylinders. To prevent the web from lifting from the wire due to pressure differences, blowing boxes are arranged to blow out air in pockets situated on opposite sides of the web. This innovative design generates a sub-pressure and excess pressure in the respective pockets, enhancing the drying process.

Another significant patent is the "Drying Plant for a Material Web." This invention includes a plurality of upper and lower blow boxes arranged parallel and at right angles to the web's traveling direction. The lower boxes support the web and are equipped with orifices for blowing air parallel to the web's plane. The upper blow boxes have orifices for blowing air perpendicularly to the web. The distance between the blowing orifices and the web is variable, allowing for adjustments to optimize energy requirements.
