WARP TENSION METER
PRINCIPLES & USE
This hand held tension comparator provides a loom operator with a visual
calibrated dial indication of warp tension. The dial readings are arbitrary
values unrelated to pounds, ounces, or grams, whereby each discernible
reading simplifies the maintenance and record keeping of the tension forces.
The reliability of this instrument is its ability to maintain repeat readings
throughout the gaging range of the warp tension force.
The above characteristics contribute to the observation and set up
of single and multi loom production applications. The warp tension
of one loom standard may be applied to the set up of another loom
producing the same fabric.
WARP PRELIMINARIES
1) Select a definite number of warp-ends (approximate 1‰ wide)
preferably towards the center of the loom and midway on its open
length. This designated number of warp-ends may be segregated for
repeat tensions checks using a wire-drop or string loop.
EXAMPLE: -60 ends for the average woolen fabric
-150 ends for 75 denier rayon.
2) The two methods of obtaining warp tension readings are with the
loom idle or running. In either case, the warp should have had a chance
to stabilize before taking readings. The stability of the idle loom offers
stable indicator readings, whereas, the running loom causes readings to
fluctuate such that the maximum and minimum values will have to be
carefully observed and/or recorded.
TENSIOMETER GAGING PROCEDURE
After having taken the “warp preliminaries” into consideration, hold
instrument in right hand as illustrated on the front cover photograph.
As defi ned in FIGURE #1, depress the thumb retract LEVER (1) to
fully retract SKI (2).
Utilizing front lip of SLED (3), enter sled under the designated warp ends
(within wire drop), so that these warp ends are centralized under the ski.
Cautiously release thumb lever allowing ski to contact the warp ends.
Remove right hand so as to allow the instrument to rest on the warp
ends remaining on the bottom surface of the sled.
The observed dial reading represents a comparative warp tension value.
This reading may be used for either monitoring and resetting a particular
loom or setting up multi-loom productions.
