Abstract
A headbox in a paper machine, which headbox has a stock outlet for a jet of stock having a specific length, angle of impact and point of encounter in relation to a nip in the wet section of the paper machine, which headbox has two stand parts, lifting arms with front and rear journalling means and a device for setting the position and alignment of the headbox so that the stock jet obtains said specific length, angle of impact and point of encounter, which setting device has two actuators mounted pivotably at the rear Journalling means of the lifting arms and at the stand parts, whereby the headbox is adjustable by means of a turning movement about said front bearing means of the lifting arms. According to the invention the setting device has two bottom plates each arranged detachably, one at each of the stand parts; an actuator support at each side of the machine having a horizontal surface and situated downstream of said front journalling means; at least one movable actuator at each side of the machine; a horizontal pressing surface on each lifting arm above the surface of the actuator support, said pressing surface and the surface of the actuator support between them defining a space for receipt of the actuator which, upon activation, lifts the headbox from the stand parts to form a space between the stand parts and the bottom plate; and a stock of spacer plates for insertion into the space for adjustment of the headbox in vertical direction.
