Abstract

The disclosure relates to an apparatus for the production of parisons from fiber-reinforced plastic, having a feed arrangement for the continuous feed of a laid fiber fabric and having a transverse deformation arrangement with a draping apparatus for the deformation of the fed laid fiber fabric to form a predefined nominal profile. The apparatus is distinguished by the fact that the draping apparatus is adjustable for a variation of a cross section of the nominal profile. The disclosure also relates to a corresponding method for the production of parisons from fiber-reinforced plastic.

First claim

The invention claimed is:

1. An apparatus for the production of preforms from fiber-reinforced plastic, comprising:
a feed arrangement for the continuous feed of a fiber fabric, and
a transverse deformation arrangement with a draping apparatus for the deformation of the fed fiber fabric to form a predefined nominal profile,
wherein the draping apparatus comprises a mold core and a first roller arrangement, for the cross-sectional fixing of the fiber fabric,
wherein the first roller arrangement comprises a roller,
wherein the draping apparatus is configured to receive the fiber fabric draped on the mold core and the draping apparatus is adjustable for a variation of a cross section of the nominal profile,
wherein the mold core comprises a first mold core part and a second mold core part,
wherein, for the variation of the nominal profile, the first mold core part and the second mold core part are adjustable relative to one another, and
wherein the mold core and the first roller arrangement are configured such that the fiber fabric travels between the mold core and the first roller arrangement.

2. The apparatus as claimed in claim 1 , wherein the draping apparatus is adjustable during a feed of the fiber fabric to the draping apparatus.

3. The apparatus as claimed in claim 1 , wherein the transverse deformation arrangement has an electronic control arrangement for the adjustment of the draping apparatus.

4. The apparatus as claimed in claim 1 , wherein the apparatus comprises a heating arrangement which is positioned upstream of the transverse deformation arrangement in terms of the feed movement and which serves for the activation of the fiber fabric, such that the fiber fabric that has been deformed to form the nominal profile is stabilized.

5. The apparatus as claimed in claim 1 , wherein the draping apparatus is adjustable for the variation of a web.

6. The apparatus as claimed in claim 1 , wherein the first mold core part and/or the second mold core part has a respective flank for the production of a first flange and of a second flange respectively.

7. The apparatus as claimed in claim 6 , wherein in a feed direction, the respective flank rises in ramp-like fashion out of a horizontal plane of the first mold core part or of the second mold core part respectively.

8. The apparatus as claimed in claim 1 , wherein the transverse deformation arrangement has a frame for receiving the draping apparatus.

9. The apparatus as claimed in claim 8 , wherein the first mold core part and the second mold core part are pivotable relative to one another.

10. The apparatus as claimed in claim 9 , wherein the second mold core part is connected by way of a pivoting connection to the frame.

11. The apparatus as claimed in claim 8 , wherein the draping apparatus has a linear drive for the adjustment of the first mold core part and of the second mold core part relative to one another.

12. The apparatus as claimed in claim 11 , wherein the linear drive imparts an action, for adjustment purposes, at a distance from a pivoting connection between the second mold core part and the frame.

13. The apparatus as claimed in claim 8 , wherein the first mold core part is rigidly connected to the frame.

14. The apparatus as claimed in claim 1 , wherein the first roller arrangement comprises convex rollers.

15. The apparatus as claimed in claim 1 , wherein the draping apparatus has a smoothing arrangement configured to smooth the fed fiber fabric.

16. The apparatus as claimed in claim 1 , wherein the draping apparatus has a second roller arrangement for the cross-sectional fixing of the fiber fabric.

17. The apparatus as claimed in claim 16 , wherein the second roller arrangement comprises concave rollers.
