Abstract

A lamella block is provided for a calibrating device for calibrating an extruded profile, wherein the lamella block includes a lamella structure, which has a plurality of lamellae that are spaced apart from each other by grooves and arranged in the longitudinal direction of the lamella block. The lamella structure has a variably designed division in the longitudinal direction of the lamella block. Further provided is a method for manufacturing the aforementioned lamella block, as well as a calibrating device, which includes a plurality of the lamella blocks mentioned above. Also provided is a system for additively fabricating the lamella blocks mentioned above, a corresponding computer program and a corresponding dataset.

First claim

What is claimed is:

1. A lamella block for a calibrating device for calibrating an extruded profile, wherein the lamella block comprises a lamella structure including first, second, third, and fourth lamella arranged in succession along a longitudinal direction of the lamella block,
wherein the first lamella is spaced from the second lamella by a first groove, the second lamella is spaced from the third lamella by a second groove, and the third lamella is spaced from the fourth lamella by a third groove,
wherein a first distance collectively spans respective widths of the first lamella and the first groove in the longitudinal direction, a second distance collectively spans respective widths of the second lamella and the second groove in the longitudinal direction, and a third distance collectively spans respective widths of the third lamella and the third groove in the longitudinal direction, and
wherein the first, second, and third distances are all different.

2. The lamella block according to claim 1 , wherein the first, second, and third distances vary continuously in the longitudinal direction of the lamella block such that first distance is greater than the second distance, and the second distance is greater than the third distance.

3. The lamella block according to claim 1 , wherein the first, second, and third distances vary randomly in the longitudinal direction of the lamella block.

4. The lamella block according to claim 1 , wherein the respective widths of the first, second, and third grooves are all different.

5. The lamella block according to claim 1 , wherein the respective widths of the first, second, and third lamella are all different.

6. The lamella block according to claim 1 , further comprising a carrier structure on which the lamella structure is arranged.

7. The lamella block according to claim 6 , wherein the carrier structure and the first, second, third, and fourth lamella are fabricated out of the same material or different materials.

8. The lamella block according to claim 1 , wherein the lamella block is integrally designed.

9. The lamella block according to claim 1 , wherein the lamella block is manufactured by means of 3D printing or an additive manufacturing process.
