A device is provided for winding paper in which the paper web running is supported by a reel drum and wound onto exchangeable reel shafts in contact with the reel drum in order to form rolls of paper. The device applies a heated adhesive agent on the web and/or on the reel shaft onto which the web is to be wound. A spray rack is mounted on the stand of the reel-up, upstream of the reel drum and extending transversely to the machine direction, or alternatively, is mounted in various other locations of the reel-up. A hopper with a heater heats the heated adhesive agent to temporarily lower its viscosity and stickiness for smooth and even spraying. A series of nozzles are mounted on the rack spaced across the width of the web to spread spray jets of liquid containing said heated adhesive onto the web and/or the reel shaft. The adhesive area thus is disposed between the web and the empty reel shaft so as to facilitate initiating the winding process.

Adhesive dispenser in a reel-up in a paper machine

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.
