Abstract

A composite manufacturing system has a tool having a substantially planar first portion and a substantially planar second portion, a first carriage configured to carry a first roller that is configured to selectively apply pressure to the first portion, a second carriage configured to carry a second roller that is configured to selectively apply pressure to the second portion, and the first carriage and the second carriage are movable relative to the tool.

First claim

What is claimed is:

1. A composite manufacturing system, comprising:
a tool comprising a substantially planar first portion and a substantially planar second portion;
a first carriage configured to carry a first roller that is configured to selectively apply pressure to the first portion;
a second carriage configured to carry a second roller that is configured to selectively apply pressure to the second portion; and
wherein the first carriage and the second carriage are movable relative to the tool;
wherein the first carriage and the second carriage are independently vertically movable relative to the tool; and
wherein the first carriage and the second carriage are restricted to vertical movements.

2. The composite manufacturing system of claim 1 , further comprising:
at least one first actuator connected between the first carriage and the first roller; and
at least one second actuator connected between the second carriage and the second roller.

3. The composite manufacturing system of claim 1 , wherein the tool comprises a curved portion joining the first portion to the second portion.

4. The composite manufacturing system of claim 3 , wherein the first roller is configured to selectively apply pressure to the curved portion prior to applying pressure to the first portion.

5. The composite manufacturing system of claim 4 , wherein the first carriage is movable relative to the tool and wherein the first roller is configured to continually apply pressure to the tool while the first carriage is moved vertically downward.

6. The composite manufacturing system of claim 5 , wherein the vertically downward movement causes the first roller to transition from applying pressure to the curved portion to the first portion.

7. The composite manufacturing system of claim 5 , wherein the first roller is configured to apply pressure to the tool at a first vertical location along the tool while the second roller is configured to apply pressure to the tool at a higher second vertical location along the tool.

8. The composite manufacturing system of claim 5 , wherein an exterior of the tool is substantially U-shaped and wherein at least one of the first roller and the second roller is configured to selectively apply pressure to more than half of the curved portion.

9. The composite manufacturing system of claim 8 , wherein a pivot block is connected between a first actuator and the first roller to allow a change in distance between the first roller and the tool.
