Abstract

In one embodiment, a pintle insertion tool is disclosed. The pintle insertion tool includes a housing, and a drive assembly supported by the housing. The drive assembly includes a controller connected to a power supply and configured to drive at least one motor. The drive assembly includes a first roller and a second roller defining at least a portion of a channel therebetween. The at least one motor is configured to rotate the first roller and the second roller in both a forward direction and a reverse direction. The channel is adapted to receive a pintle lead wire such that the pintle lead wire is driven by the first roller and the second roller through interdigitated seam loops on opposing ends of a textile sheet so that a pintle can be pushed into position to complete a seam.

Claims (25)

1. A pintle insertion tool comprising:

a drive assembly including a controller connected to a power supply and configured to drive at least one motor,

a first roller and a second roller defining at least a portion of a channel therebetween, the at least one motor configured to rotate the first roller and the second roller, and

the channel is adapted to receive a pintle lead wire such that the pintle lead wire is driven by the first roller and the second roller through interdigitated seam loops on opposing ends of a textile so that a pintle can be pushed into position to complete a seam.

2. The pintle insertion tool of claim 1 , wherein the drive assembly further comprises a gear set arranged between the at least one motor and the first and second rollers.

3. The pintle insertion tool of claim 2 , wherein the gear set includes a reduction gear.

4. The pintle insertion tool of claim 1 , wherein the controller is a remote controller.

5. The pintle insertion tool of claim 1 , wherein the at least one motor includes a first motor and a second motor, and the first and second motors are adapted to be driven at an identical speed in opposite directions by the controller.

6. The pintle insertion tool of claim 1 , wherein the drive assembly is supported by a stationary housing.

7. The pintle insertion tool of claim 1 , wherein the power supply is a DC power source.

8. The pintle insertion tool of claim 1 , wherein the at least one motor is a variable speed motor.

9. The pintle insertion tool of claim 1 , wherein the at least one motor is drivable in both a forward direction and a reverse direction.

10. A method of inserting a pintle, the method comprising:

(i) providing a pintle insertion tool comprising:

a drive assembly including a controller connected to a power supply and configured to drive at least one motor,

a first roller and a second roller defining at least a portion of a channel therebetween, the at least one motor configured to rotate the first roller and the second roller, and

the channel is adapted to receive a pintle lead wire;

(ii) positioning the pintle insertion tool adjacent to opposing sheet ends, each of the opposing sheet ends defining a plurality of seam loops; and

(iii) inserting a pintle lead wire into the channel defined by the pintle insertion tool, such that pintle lead wire is driven through the plurality of seam loops which are interdigitated to install a pintle to close a seam between the opposing sheet ends.

11. The method of claim 10 , wherein the drive assembly further comprises a gear set arranged between the at least one motor and the first and second rollers, and the gear set includes a reduction gear.

12. The method of claim 10 , wherein the at least one motor is a variable speed motor, and the at least one motor is drivable in a reversible direction.

13. The method of claim 10 , wherein the at least one motor includes a first motor and a second motor, and the first and second motors are adapted to be driven at an identical speed in opposite directions by the controller.

14. The method of claim 10 , wherein the pintle insertion tool is inactive during step (ii),

the pintle lead wire is manually inserted into a subset of seam loops of the plurality of loops provided along an outermost edge of the sheet ends during step (ii), and

the pintle insertion tool is activated after the pintle lead wire is manually inserted into the subset of seam loops.
