Press for a fiber web supported by a clothing, said press having first and second press elements that interact with each other in order to form an extended nip in a press zone for the clothing-supported fiber web, said first press element having: &#x2014;a support; &#x2014;a press body, being supported by the support; &#x2014;an endless, flexible belt, sliding over and forming a closed loop around the press body; and &#x2014;a support element, being placed inside the loop for supporting the belt, said clothing surrounding together with the belt between a first position and a second position along the loop, wherein at least the first position is located outside the press zone. According to the invention, the support element is located in the first position. The invention also relates to a method in, and a press element for such a press.

A method of ensuring the flatness of a vane that is mounted in a headbox by means of a mounting arrangement including engagement dowels for cooperation with a downstream support wall of a transverse groove, said vane being affected during operation by shearing forces from the stock and by retaining forces from the mounting arrangement. In accordance with the invention outer engagement dowels are mounted at the side edges of the vane to cooperate during a specific period of time, as the only engagement dowels with the downstream support wall in order to take up said shearing forces, whereby tensile stresses will arise in the downstream end portion of the vane in the cross machine direction. The invention also relates to a headbox having such a mounting arrangement and the mounting arrangement per se in which the vane within and downstream of an inner area of the upstream end portion of the vane is arranged to move freely in the machine direction in relation to said downstream support wall during said period of time.
