Abstract

Some embodiments include a fabric separator comprising a body, a drum, a gas intake, a sensor, and a clamp. In some embodiments, the drum has an outer surface, is coupled with the body, and has a drum rotatable about an axis. The gas intake may flow gas in a rotational direction of the drum such that a low pressure zone is created on at least a portion of the outer surface of the drum. The sensor may be coupled with the body. The clamp may be in communication with the sensor and coupled with the body. The clamp having an engaged mode where the clamp is pressed against a portion of the drum and a disengaged where the clamp is not pressed against a portion of the drum, the clamp transitions from the engaged mode to the disengaged mode based on a signal from the sensor.

First claim

That which is claimed:

1. A fabric separator comprising
a body;
a drum with an outer surface coupled with the body, the drum rotatable about an axis, wherein a cavity is defined by one or more walls of the body and the drum, and wherein the one or more walls at least partially enclose the cavity;
a gas intake that receives gas external from the body and flows the gas into the cavity in a rotational direction of the drum sufficient to cause the drum to rotate, wherein the rotation of the drum amplifies an effect of the flow of gas to create a low pressure zone along a surface of the drum that is opposite the cavity as the drum rotates in response to the gas flow;
a flagging sensor coupled with the body; and
a clamp in communication with the flagging sensor and coupled with the body, the clamp having an engaged mode and a disengaged mode, in the engaged mode the clamp is pressed against a portion of the drum and in the disengaged mode the clamp is not pressed against a portion of the drum, the clamp transitions from the engaged mode to the disengaged mode based on a signal from the flagging sensor.

2. The fabric separator according to claim 1 , wherein the low pressure zone is located between the drum and a fabric ply stack.

3. The fabric separator according to claim 1 , wherein the gas is pressurized gas and the drum is rotated by the gas flow.

4. The fabric separator according to claim 1 , wherein the gas intake has an outer opening disposed outside the body and an inner opening disposed near the drum wherein a diameter of the outer opening is larger than a diameter of the inner opening.

5. The fabric separator according to claim 1 , wherein the gas intake has a substantially frustoconical shape.

6. The fabric separator according to claim 1 , wherein the clamp comprises a linear actuator that when actuated moves the clamp into the engaged mode and when unactuated moves the clamp in the disengaged mode.

7. The fabric separator according to claim 1 , wherein the clamp comprises two members that extend away from the body in the disengaged mode and articulate toward the surface of the drum in the engaged mode.

8. The fabric separator according to claim 1 , wherein the flagging sensor comprises an infrared sensor.
