Machine Selection

The following can be used as a guide to braid machine selection:

Quantity of Carriers
in Braider
Wire Bundle Range Diameter
24
 1/4" to 1/2" (6.35 to 12.7 mm)
32
 5/8" to 3/4" (15.8 to 19 mm)
48
 3/4" to 1 1/2" (19 to 38.1 mm)
64
 1 1/2" & Larger (38.1 mm & Larger)

How to Estimate Amount of Braid Yarn Required for a Harness

The following relationship may be applied: Ø = Braid Angle L = Harness Length L' = Yarn Length

Total Yarn Length, L'
=
 (# Carriers, N x Dia. Braid, D x 3.14) / (CosØ)
Pounds Req'd, W
=
 (Total Yarn Length, Yds.) / (*Yds./Lb.)
*Yield - Braid Yarn
Vinyl 0.028 inches = 1,000 Yds/Lb.
Vinyl 0.040 inches = 550 Yds./Lb.
Example:
   L' = (16 x 1 x 3.14) / (0.71)
L' = 70.8 in. Yarn Per Inch of Braid
Cos 45° = 0.71
(70.8 / 36 in/yd) / 1000 YPP = 0.002 Lbs Per Inch of Harness
