Abstract (en)

[origin: US6027613A] Suction device for use in a machine for producing a sheet and a method to vacuum a web section of a paper machine. The suction device includes a contact surface to place on the web section and a suction box. The suction box is designed to have a vacuum pressure applied to drain the web section. The suction device further includes a control device and a release mechanism or an adjustment mechanism for releasing the suction box from the web section while the vacuum pressure is applied or thereafter so that the web section is guided along the contact surface with less friction and without the web section detaching from the contact device. A method to suction a web section in a paper machine including arranging a contact surface a suction device on the web section and applying a vacuum pressure to the suction device to vacuum the web section. The method further includes operating the paper machine to guide the web section along the contact surface and pressing the web section onto the contact surface by the vacuum pressure. Finally, the method includes releasing the suction device from the web section at the time of or after applying the vacuum pressure thereby guiding the web section along the contact surface with less friction and without the web section detaching from the contact surface.
