His work primarily revolves around innovative methods and devices that enhance the functionality of machinery, particularly in the paper and board manufacturing industry.
Latest Patents
Martti Pullinen's latest patents exemplify his ingenuity and technical expertise. One of his prominent inventions is a "Method and device in an adjustable-crown roll." This method utilizes a series of hydraulic loading elements, supporting the central axle of the roll through deflection bearings. The innovative design features an optimally shaped central axle that maintains high rigidity within the nip plane. The method allows for the rotation of the central axle over an angle ranging from approximately 30 degrees to 180 degrees, creating a flexible opening gap between the axle and the roll mantle. This enables efficient adjustments to the roll mantle's position, influenced by gravity or affirmative shifting, thus improving the functionality of the variable-crown roll.
Another significant patent by Pullinen is the "Apparatus for coating a web." This apparatus is designed to coat materials such as paper or board by facilitating a coating nip formed between a rotating counter roll and either a smoothing member or another pair of smoothing members. It incorporates an adjustable arrangement for the linear load in the coating nip, which allows for precise control over the quantity and distribution of the coating substance applied to the web. The flexibility of the elongate smoothing member also enables the load distribution to vary significantly across short distances, optimizing the coating process.
