GENERAL INFORMATION

1. For best wire straightening the plane of the K281rolls (A) should be as close as possible to the plane of the wire reels.

2. The K281 moving arm (B) should be pointing toward the wire reels and the adjusting knob (C) should be away from the reels.

3. The K281 can be mounted to the wire drive in two different positions. The head can then be positioned to meet the above requirements.

INSTALLATION

1. Remove the Spring Wire Guide if installed.

2. Remove the K129 Ingoing Guide Tube.

3. Insert the new Ingoing Wire Guide (with ceramic inserts) that comes with the K281.

4. Position the K281 over the wire guide as outlined above and tighten the two hex head screws.

WIRE LOADING AND ADJUSTMENT

1. Turn the adjusting knob (C) to the maximum open position.

2. Remove the top ingoing guide block (D) by loos- ening the thumb screw (E).

3. Straighten the first 10” (254mm) of each wire (the straighter the wire the easier to load).

Under Over

Straightened Straightened

The tips should be in line with the O.D. of the drive rollsfor initial strightening adjustment. If the wires bow to the right when inched down through the tips they are being over straightened. If the wires bow to the left, they are being understraightened. Adjust the knob until the wires come out parallel and uniform.

Depending on how the wire enters the K281, there may be some side bow. Slight rotation of the K281 may eliminate this condition.

Once the wire is sufficiently straight, the tip orientation can be changed to whatever angle between “in-line” and “cross seam” is required.

For overlay applications with Tiny Twinarc, a NOTE: special side by-side tipholder (Part # S17728

is available that accepts standard tips.
