Device for applying adhesive in a slitter-winder of fiber web machine

1. A device for applying adhesive in a slitter-winder of a fiber web machine, wherein the slitter-winder comprises:

an unwinder for unwinding a machine roll in a running direction defined by a fiber web which is unwound from the machine roll;

slitter blades for slitting the fiber web unwound from the machine roll into partial webs;

a winder for winding the partial webs onto fiber web rolls;

wherein the device for applying adhesive further comprises:

a moving element mounted for movement with respect to the unwinder on a support structure in a cross-direction in relation to the running direction of the web;

two adhesive nozzles that are attached to the moving element such that the nozzles are spaced apart in the cross-direction on the moving element;

wherein the two nozzles are fitted to apply adhesive on ends of the partial webs for attaching the ends of the partial webs onto the fiber web rolls;

two carrier beams that form part of a frame structure of the slitter-winder and are positioned on either side of the fiber web;

wherein the moving element defines a movement path across the partial webs; and

wherein said each of the two nozzles has a home position at one cross directional end of the movement path across the partial webs, in which one of the nozzles is as close as possible to the immediate vicinity to one of the two carrier beams.

2. The device of claim 1 wherein the two nozzles are attached symmetrically in respect to a middle line defined by the moving element; and

wherein the two nozzles extend to opposite directions in a cross-direction in relation to the running direction of the web.

3. The device of claim 1 wherein each of said two nozzles further comprises:

a nozzle arm attached to the moving element; and

a nozzle head mounted to the nozzle arm.

4. The device of claim 1 further comprising:

a source of adhesive in supply relationship to each of the two nozzles; and

a controller arranged to individually control a flow of adhesive from the source of adhesive to each of the nozzles that is applying adhesive.

5. A device for applying adhesive and a slitter-winder of a fiber web machine comprising:

an unwinder for unwinding a machine roll formed of a fiber web in a running direction, which direction is defined by the fiber web which is unwound from the machine roll;

slitter blades arranged to slit the fiber web unwound from the machine roll into partial webs;

a winder arranged to wind the partial webs onto fiber web rolls;

a moving element mounted for movement with respect to the unwinder on a support structure in a cross-direction in relation to the running direction of the web;

two adhesive nozzles that are attached to the moving element by arms such that the nozzles are spaced apart in a cross-direction in relation to the running direction of the web on the moving element and extend away from each other on the arms so that the arms extend in opposite directions in the cross-direction; and

wherein the two nozzles are connected to a supply of adhesive and arranged to apply adhesive onto ends of the partial webs for attaching the ends of the partial webs onto the fiber web rolls, the nozzles arranged such that one of said nozzles extends away from the direction of travel so it can be accelerated to operating speed before traversing the partial webs, and the other of said nozzles can extend further in the direction of travel than the moving element can move.
