Abstract

A fiber composite laying device for manufacturing a fiber composite scrim for forming a fiber composite component, includes a laying head, which is configured to supply a fiber composite band continuously in a supply region. A laying roller is configured to receive the fiber composite band from the supply region to unroll it towards a laying surface and to press it onto the laying surface in a laying region. A press is located between the supply region and the laying region and is configured to press the fiber composite band onto the laying roller in a pressing region. A cutter is configured to cut the fiber composite band to length between the supply region and the pressing region.

First claim

What is claimed is:

1. A fiber composite laying method for producing a fiber composite scrim for forming a fiber composite component, the method comprising:
supplying a fiber composite band in a supply region of a laying head;
unrolling the fiber composite band using a laying roller;
pressing the unrolled fiber composite band onto a laying surface in a laying region using the laying roller;
pressing the fiber composite band onto the laying roller in a pressing region using a press, the pressing region being arranged between the supply region and the laying region; and
cutting the fiber composite band to length between the supply region and the pressing region using a cutter.

2. The method of claim 1 , wherein the pressing is carried out using a contact pressure, the method further comprising monitoring the contact pressure.

3. The method of claim 2 , further comprising controlling the contact pressure.

4. The method of claim 2 , wherein the contact pressure is generated mechanically, hydraulically and/or pneumatically.

5. The method of claim 1 , wherein the pressing region is located in a direct vicinity of the laying region.

6. A fiber composite laying device for manufacturing a fiber composite scrim for forming a fiber composite component, the device comprising:
a laying head configured to supply a fiber composite band continuously in a supply region;
a laying roller configured to receive the fiber composite band from the supply region, to unroll the fiber composite band towards a laying surface, and to press the fiber composite band onto the laying surface in a laying region;
a press located between the supply region and the laying region and configured to press the fiber composite band onto the laying roller in a pressing region; and
a cutter configured to cut the fiber composite band to length between the supply region and the pressing region.

7. The fiber composite laying device of claim 6 , wherein the press is formed as an actuator formed with a movable pressing surface.

8. The fiber composite laying device of claim 6 , wherein the pressing surface forms a surface of a roller, which is rotatable counter to the laying roller, so as to move the fiber composite band between the press and the laying roller in a direction of the laying surface during pressing.

9. The fiber composite laying device of claim 6 , wherein the pressing surface is formed as a portion of a cylinder outer surface, which is shaped so as to be complementary to a surface portion of the laying roller.

10. The fiber composite laying device of claim 6 , wherein the press is displaceable towards and away from the laying roller automatically.

11. The fiber composite laying device of claim 6 , wherein the pressing surface and the laying roller are made of the same material at least at the surface.

12. The fiber composite laying device of claim 6 , wherein the press is fixed to a lever arm so as to be pivotable towards the laying roller for the pressing.

13. The fiber composite laying device of claim 6 , wherein the press is configured to generate a contact pressure mechanically, hydraulically and/or pneumatically.

14. The fiber composite laying device of claim 13 , further comprising:
a control configured to detect, evaluate and control instantaneous contact pressure.

15. The fiber composite laying device of claim 6 , wherein the laying roller and/or the press are provided with lateral guide elements which fix the fiber composite band in an unrolling orientation.
