b. Cut component parts from same piece of the basic material, except the undercollar, pen pocket, the under parts of the pocket flaps, shoulder loops, stay holder, collarstands, cuffs, collar leaf, and yoke which may be cut from ends. Parts cut from ends shall approximate the shade of the other parts. The binding for sleeve opening may be cut of sufficient length and width to meet the requirements of operation 1 5. The binding may be put rolls.

c. Cut the polyester fiber interlinings and the fusible interlinings in accordance with directional lines on patterns.

7. NOTES

(This section contains information of a general or explanatory nature that may be helpful, but is not mandatory.)

7.1. Intended use. The long sleeve shirts are intended for wear by male cadets at the United States Military Academy.

7.2. Acquisition requirements. Acquisition documents should specify the following:

a. Title, number and date of this purchase description.

b. Type and size required (see 1.2).

c. Material required (see 3.2).

7.3. Samples. For access to samples, address the contracting activity issuing the invitation for bids or request for proposal.

7.4. Seam appearance. In order to avoid puckering and to produce the flattest seams possible, consideration must be given to the following:

a. The needles used for all seams should be as fine as possible consistent with the size or diameter of the thread used.

b. The throat plate hole should be no larger than necessary to permit free entry of the needle and to prevent flagging.

c. The finest feed (approximately 18 teeth) possible should be used with a pressure foot to exactly match the shape and size of the feed. The face of the pressure foot (underside next to the feed on the machine) should be highly polished to eliminate roughness and reduce drag. Diamond shaped feed teeth have been used quite successfully.

d. The lightest foot pressure should be used to prevent stretching of the top ply of material.

e. In the safety stitch machine (515, 516, and 519), the upper and lower trimming knives should be kept at peak sharpness to prevent "dragging" of the edge of the fabric.

f. In stitch type 301 sewing, the bobbin tension should be adjusted to that when a full bobbin is placed in the bobbin case and threaded through the tension spring, the bobbin and case shall ride slowly down the thread when the free end of the thread is held in the vertical position. Needle tension should be adjusted after the bobbin tension to provide slightly more needle thread than bobbin thread in the stitch.

g. When sewing the stitch type 401 (including the seaming row of the safety stitches), the thread ratio (needle and looper) should be adjusted to produce a stitch with 60 to 70 percent needle thread, and both needle and looper thread tension shall be held to the minimum.

h. Thread take-up mechanism should be set on all machines to relieve as much tension as possible when forming the stitch. All thread contacts should be well polished and free of burrs, cuts and rough spots.

7.5. Use of automated apparel equipment. Automated creaseband construction is the creases and tack process from Facemate Corporation.

7.6. Ultrasonic welding conditions. The following Ultrasonic welding conditions have been found to provide welds meeting the requirements of this document. These limits are furnished for guidance only. For optimum results with a particular ultrasonic machine used, specific machine settings should be obtained from the manufacturer of the ultrasonic equipment

Minimum Maximum Pressure, psi 35.0 40.0 Weld time, seconds 0.2 0.3 Down speed, inches/minute 10.0 12.0 Trigger pressure, pounds 8.0 10.0 Hold time, seconds 0.0 0.05
