High Turnout of SPCL CIRCULAR LOOM
SERIES
It's known to all, for same type of fabrics
the way to increase turnout of circular loom is increasing cast rate and
running time.
1. cast rate = shuttle number x rotate speed of main motor
so the first method is to increase shuttle
number, then to increase the rotate speed.
a. increase number of shuttle---A way to hold knots
in manufacture of circular loom
As the manufacture technique goes mature. the shuttle's
number also increased. For small model , Light 6-shuttle taking place of
4-shuttle;for medium scale 8-shuttle taking place of 6-shuttle;for
large-scale 10-shuttle taking place of 8-shuttle---the reason is turnout
for certain speed of main motor,6-shuttle is 1.5 times of 4-shuttle,
8-shuttle is 1.33 times of 6-shuttle and 10-shuttle is 1.25 times of
8-shuttle respectively, it's obvious that increasing shuttle's number is
great helpful to higher turnout.
SPCL CIRCULAR LOOM SERIES emphasize particularly on
8-shuttle,10-shuttle and 12-shuttle, the motive is to pursue lead turnout.
b.boost main motor speed---The way to burden
painfully by both of circular loom manufacture and plastic weaving field
As the whole level of plastic weaving being improved,the rpm
speed of circular loom is also boosted. Meanwhile three problems arised: 1
if the quality of weft can meet the demand for high speed weaving;2 if
plenty of heat due to friction of warp with shuttle can fire break the
warp;3 the quantity and lifetime of easy wear parts of circular loom.
SPCL CIRCULAR LOOM SERIES not only aims at high speed, high
efficiency , two inverters enable each type of SPCL CIRCULAR LOOM SERIES
speed-adjustable from low to high to meet different fabrics demands for
diffierent customers, lays solid fundation for device capablity and
technics level of plastic weaving field.
2.real running time=working time-downtime
Downtime includs
weft-change,weft-break,warp-break,device-fail, among these,weft-change
downtime occupys the most,hence to increase real tunning time is firstly
to decrease weft-change time,also to increase weft length for every batch.
SPCL CIRCULAR LOOM SERIES mainly increase capcity of single weft
package to realize it.
SPCL CIRCULAR LOOM SERIES 's weft diameter is 11---12cm,weft
capacity is 1.62 times of weft diameter(9---10cm).
(11*11-4.04*4.04)/(9*9-4.04*4.04)=1.62
3.Typical fabrics(180g/m2, density14*14/inch, folded

(5)weaving
loop for each batch of weft 8193m/3.6m=2276 loops,
weaving fabric length for each batch of weft
(2276*8)*25.4/14/1000=33m,
weaving time for each batch of weft 2276/60=37.9 minutes,
change time of weft from batch to batch 22.5*8/60=3 minutes,
weaving batches during 24 hours 24*60/(37.9+3)=35.2 batches,
theoretic weaving turnout every 24 hours 33*35.2=1161.6m,
real weaving turnout every 24 hours 1161.6*.9=1045m.
High Quality of Fabrics by SPCL
CIRCULAR LOOM SERIES
Fabric quality includes aspect quality and inner
quality
SPCL CIRCULAR LOOM SERIES adopts patent technology "Swallow-tail
guide rail pair for plastic circular loom"
(patent
no. ZL 96 2 17570.6 or Application
Number: CN19960217570U at esp@cenet)
leads to less loss of strength in weaving process, so that high stregth of
fabric can be obtained.
For typical fabrics (180g/m2, density 14*14/inch,folded diameter 1.8m,perimeter
3.6m):
(1)warp width
1.8mm,thickness 0.098mm,fibre number 1450 Danial
(2)weft width

SPCL CIRCULAR LOOM SERIES introduces advanced dual inverter control
system and warp-weft break control system resonably, warp/weft break
compensate value and weft density can be adjusted rapidly as
required during weaving so that the affection of yarn break can be
decreased to the least extent.
Low power consumption of SPCL
CIRCULAR LOOM SERIES
SPCL CIRCULAR LOOM SERIES utilizes advanced 3D cam
to change sliding friction in warp's open across system to rolling
friction,lower the friction rate greatly, the whole load as well,main
motor for 8-Shuttle Circular Loom is 7.5kW,for 10-Shuttle Circular Loom is
11kW,and real running load are between 55%---68%.
As stated already,SPCL CIRCULAR LOOM SERIES resonablely adopts
advanced dual inverters control system, gains prominent power-saving
result.

High Reliability and Low
maintenance of SPCL CIRCULAR LOOM SERIES
To reduce easy-wear parts of SPCL CIRCULAR LOOM SERIES and extend
their working life espically improve reliablities of key parts as possible
as we can:
1.Select base parts, standard parts from famous manufacturer, such
as motors,bearings,gear box etc..
2.Reconstruct old structures with new technology, no shuttle
wheels, no weft density gear, no slider, no slider shank for SPCL CIRCUlAR
LOOM SERIES,decrease easy-wear parts again and again.
Extreme low consumption of electricity proves that machine parts'
wear and tear is quite little for SPCL CIRCULAR LOOM SERIES.
