Beasley Balance For warp & weft count from a fabric-with 2nos. Riders & a template.
The count of yarn is defined as a number indicating
its weightage. In direct system, the
count is the weight of a unit length of yarn for example - “TEX” is number of grams in one kilometer
length of yarn, “DENINER” is number of grams in 9000 meters of Yarn. In
INDIRECT System, the count is the number of units of fixed length of yarn which
makes a fixed weight for example “COTTON” is number of hanks of yarn in a
pound. “METRIC” is number of kilometers of yarn in one Kilogram.
Irrespective of the system of count, two basic
requirements for determining count are :
- An accurate determination of sample length ; and
- An accurate determination of its weight.
The method of determination of count depends to a
large extent on the form in which the yarn is available for testing. When a
yarn is in the form of a Bobbin, a known sample length can be taken by forming
a skein on a WRAP REEL and
suspending it on the hook of “QUADRANT
BALANCE”. The count is then read
directly from the Quadrant Scale. When
warp and weft count of yarn, taken from a small piece of fabric is required, it
is cut into small lengths with a template and the total number of yarn lengths
which are required to balance a standard weight on the beam directly gives the
count of the yarn. This measurement is
carried out with the help of a Beasley Balance.
The ‘VGOTECH’ Beasley Balance consists of a light
weight beam pivoted on jewel bearings with a hook at one end and a pointer at
the other. The beam is initially leveled
to bring the pointer against a Datum line.
A standard weight is suspended in a notch on the beam arm on the pointer
side. A template is used to cut short
lengths of yarn, the length depending upon the count system required. These length are placed on the hook until the
pointer comes against the Datum line.
The number of short lengths required to balance the beam gives the count
of the yarn.
A template is provided to give lengths of yarn in “METRIC”, “COTTON”, “LINEAN”, “WOOLSKEIN” and
“WORSTED” counts. The balance is housed in a beautiful painted
metal case having sliding transparent acrylic doors.
