A cinch valve includes an upper plate having a first aperture; an orbital plate rotatable relative to the upper plate and having a second aperture substantially aligned with the first aperture; an actuator coupled to the orbital plate arranged to rotate the orbital plate between a first position and a second position; and a plurality of cables each having a flexible portion and each having a first end and a second end, wherein each first end is coupled to the upper plate and each second end is coupled to the orbital plate. Rotation of the orbital plate from the first position to the second position causes the plurality of cables to converge and form a woven closure in approximately the center of the second aperture.

1. A cinch valve comprising: an upper plate comprising a first aperture;an orbital plate rotatable relative to an upper plate and comprising a second aperture substantially aligned with the first aperture;an actuator coupled to the orbital plate arranged to rotate the orbital plate between a first position and a second position; anda plurality of cables each comprising a flexible portion, each cable having a first end and a second end, wherein each first end is coupled to an upper plate and each second end is coupled to the orbital plate;wherein rotation of the orbital plate from the first position to the second position will cause the plurality of cables to converge and form a woven closure in approximately the center of the second aperture, andwherein the plurality of cables are configured such that, when the cables converge and form the woven closure, each one of the cables: passes over a first other cable and a second other cable, passes under a third other cable, and passes under the first other cable. 2. The cinch valve of claim 1 comprising a lower plate having a third aperture substantially aligned with the first and second apertures, wherein the orbital plate is disposed between the upper and lower plates. 3. The cinch valve of claim 2 comprising a plurality of grooved bearing assemblies coupled to the upper and lower plates, each grooved bearing assembly comprising a groove arranged to receive an edge of the orbital plate. 4. The cinch valve of claim 1 wherein the actuator is a linear actuator comprising a rod coupled to the orbital plate, and retraction of the rod causes rotation of the orbital plate from the first position to the second position. 5. The cinch valve of claim 1 wherein the actuator is a linear actuator comprising a rod coupled to the orbital plate, and extension of the rod causes rotation of the orbital plate from the first position to the second position. 6. The cinch valve of claim 1 wherein substantially the entirety of each cable is flexible. 7. The cinch valve of claim 1 wherein the plurality of cables are configured such that, when the orbital plate is in the first position, each cable is entirely positioned between first plate and the orbital plate. 8. A bulk bag unloading apparatus comprising: a frame arranged to support a bulk bag;a cinch valve coupled to the frame and disposed proximate to a spout end of the frame, the cinch valve comprising: an upper plate comprising a first aperture;an orbital plate, rotatable relative to an upper plate, and comprising a second aperture substantially aligned with the first aperture;an actuator coupled to the orbital plate arranged to rotate the orbital plate between a first position and a second position; anda plurality of cables each comprising a flexible portion, each having a first end and a second end, wherein each first end is coupled to an upper plate and each second end is coupled to the orbital plate;wherein rotation of the orbital plate from the first position to the second position causes the plurality of cables to converge and form a woven closure in approximately the center of the second aperture, andwherein the plurality of cables are configured such that, when the cables converge and form the woven closure, each one of the cables: passes over a first other cable and a second other cable, passes under a third other cable, and passes under the first other cable. 9. The apparatus of claim 8 comprising a paddle-type unloader coupled to the frame and disposed proximate to the spout end of the frame. 10. The apparatus of claim 8 wherein the cinch valve comprises a lower plate having a third aperture substantially aligned with the first and third apertures, wherein the orbital plate is disposed between the upper and lower plates. 11. The apparatus of claim 10 wherein the cinch valve comprises a plurality of grooved bearings coupled to the upper and lower plates, each grooved bearing comprising a groove arranged to receive an edge of the orbital plate. 12. The apparatus of claim 8 wherein the actuator is a linear actuator comprising a rod coupled to the orbital plate, and retraction of the rod causes rotation of the orbital plate from the first position to the second position. 13. The apparatus of claim 8 wherein the actuator is a linear actuator comprising a rod coupled to the orbital plate, and extension of the rod causes rotation of the orbital plate from the first position to the second position. 14. The apparatus of claim 8 wherein substantially the entirety of each cable is flexible. 15. The cinch valve of claim 8 wherein the plurality of cables are configured such that, when the orbital plate is in the first position, each cable is entirely positioned between the upper plate and the orbital plate. 16. A cinch valve comprising: a plate comprising a first aperture;a plurality of cables, each cable comprising a flexible portion, wherein one end of each cable is mounted to the plate; andmeans for causing the plurality of cables to converge and form a woven closure in approximately the center of the first aperture,wherein the plurality of cables are configured such that, when the cables converge and form the woven closure, each one of the cables: passes over a first other cable and a second other cable, passes under a third other cable, and passes under the first other cable. 17. The cinch valve of claim 16 wherein substantially the entirety of each cable is flexible. 18. The cinch valve of claim 16 wherein the plurality of cables are configured such that, when the means for causing comprises an orbital plate, and when the orbital plate is in a first position, each cable is entirely positioned between the plate and the orbital plate.
