2. Italian textile machinery manufacturer since 1901
Bigagli has been producing textile machinery since 1901 and is one of the most
recognized name in the history of the woollen yarn textile machinery. Our
company is established near Florence in the Prato textile district.
Our awareness, that the quality of the yarn cannot ignore the quality of the
equipment used to produce it, has led us to always seek the most advanced
technologies to assist textile’s company all over the world to produce high
quality woollen yarns.
We specialized over the years in manufacturing modern and advance woollen
spinning frames, known as Bigagli self acting mules, specifically designed,
developed and constantly improved to produce fine and extra fine woollen
yarns; through processing natural, fine and delicate fibers such as cashmere,
angora, vicuňa, camel hair and their blends with fine wool.
Our dedicated effort and passion for quality, which has been inherited from long
experience, are the fundamental driving force of our development to ensure,
through our Made in Italy textile machinery, production of consistent and high
quality yarn for our customers .

8. Why the mule spinning frame (1)
The mule spinning frame guarantees the production of very high-quality woollen
yarns offering the following main advantages

continuous draft on a 3 to 6 m- field, well above the ring spinning system.
Recent laboratory tests confirmed that draft is more natural (no fiber or yarn stress)
and homogenous, because the tensile force is spread across a much wider path
length

Continuous yarn twist (without the false twist of the ring spinning system)
The yarn is constantly twisted before and after being spooled, thus preventing the
uneven fiber relief on the winding axis and keeping the Uster uniformity index
extremely high. The risk of ends breakage during the drafting operation is reduced
when short and/or fine fibers are present, such as cashmere and angora or fibers of
different type, fineness and length.

www.bigagli.net - Made In Italy Textile Spinning Machinery since 1901

9. Why the mule spinning frame (2)

The self acting mule enables to produce a vast range of yarn counts.
The ring frame can spin yarn counts only according to the ring diameter while the self
acting mule can spin from yarn count Nm 4000 up to yarn count Nm 46000.

The self acting mule allows to produce higher quality yarns which cannot
be made successfully by a ring spinning frame
This characteristic is easy to verify when comparing the trial canvas. When
considering the spinning procedure based on the coordinated action of draft and
twists; we must keep in mind that twists are more concentrated on the thinner yarn
segments and draft are more incisive on the thicker yarn segments in order to thinner
them and obtain a uniform yarn.
This spinning operation is more effective on the self acting mule because draft and
twists act at the same time on a length of 3-4 meters (yarn path length) while on
the ring spinning system this length is reduced in about 20 centimeters only.
Moreover in order to carry out this operation on the ring there is one more procedure
- the false twist.This is due to the fact that, without false twist, draft and twists would
be not contemporaneous on the ring.

www.bigagli.net - Made In Italy Textile Spinning Machinery since 1901

10. Why the mule spinning frame (3)

The modern self acting mule represents a cost energy saving textile
machinery
The self-acting mule consumes less energy than the ring spinning frame because
on the ring there is one more motor (for the false twist) and the winding of the yarn
on spindle is obtained through the friction of slider on ring.

The self acting mule offers a competitive pricing
Considering the same production quantity (matching with the carding set), the
self-acting mule’s price is lower than the ring spinning frame price.

The only advantage of the ring spinning system lies in the fact that for the
same production quantity the spinning ring frame requires a reduced space
compared with the self-acting mule.

15. Self acting mule spinning cycle :
outward stage and backing-off
A. Outward stage – draft and twists: during this first phase the bobbin¹ holder
carriage moves away from the spindles rail. Whilst this is going on a certain
quantity of yarn is fed and the spindles rotate simultaneously at high speed.
Since the yarn feeding is less than the space covered by the bobbin holder
carriage, the yarn is drafted of a certain percentage (set by the operator).
During all this phase the spindles rotate while giving a certain number of
twists per meter, programmed by the operator too. At the end of this first
phase the bobbin holder carriage will be completely opened (in the farthest
distance position away from the spindles). The yarn is processed.
B. Backing-off: preparation
for winding stage (processed yarn is winding on
spindle). The faller² moves down to reach its winding position. The counterfaller³ moves up in order to tension the processed yarn.
Note: Bobbin1 = product coming from carding set - Faller2 = mechanical part
relative to yarn placing on the spindle
15
www.bigagli.net - Made In Italy Textile Spinning Machinery since 1901

16. Self acting mule spinning cycle :
inward stage and fallers stroke
C. Inward stage – winding: the bobbin holder carriage comes back to the start
position at high speed while the spindles turn so as to wind the yarn on the
spindle in the position determined by the faller position and with tension
imposed by counter-faller3.
D. Fallers
stroke: when the bobbin holder carriage has reached the start
position, the yarn has been completely winded on the spindle, the faller
springs up quickly to reach its parking position. In the meantime the counterfaller quickly springs down in order to reach its parking position, making free
the yarn and preparing the machine for the next yarn path (starting process
from phase A).
Note: Counter-faller3 = mechanical part rrlative to tensioning of yarn on the
spindle
16

17. Self acting mule spinning cycle features
 For each yarn path (phase A+B+C+D) the quantity of yarn produced is given
by the length of yarn path multiplied for the number of spindles. In order to match
the self-acting mule with a carding set, spindles have to be 2,5 times the number
of good ends of carding set (with yarn path 4 mt. on the self-acting mule)
 The
self-acting mule spinning process can include additional phases as for
example jacking-in and/or extra feeding that enable to reduce yarn brakes due to
the high number of twists per meter.

18. Mule spinning frame mod. B7 DD :
main advantages
 Maximise production capacity reducing downtimes
The possibility of operating on a single section reduces the total spinning
machine downtimes, related to cop replacement, bobbins replacement and
generally speaking all the machine stops carried out through the switch bar.
Indeed a section can be stopped meanwhile the other section can continue
to work normally.
 Increase of quality standard and performance
Mechanical, electronic and software improvements have permitted to produce
very fine and delicate yarns like cashmere 100% up to count Nm 46.
 More flexibility for an easier management of small lots and lot ends
The two independent sections of the spinning self acting mule recent model B7
DD allow to process two different yarns at the same time as if you would
have two self acting mules operating simultaneously. The main advantages of
such an improvement are related to the production flexibility achieved when it
comes to small lots production and lot ends.

The movement of the mule spinning machine B7 Double Drive model is
granted by 12 Siemens brushless motors controlled by the Siemens
"Sinamics" module while Simotion is the system that handles the Motion
Control tasks – from basic to highly complex tasks, focusing on flexible
solutions.

25. Operator interface
The machine can
be fully controlled
through intranet
network and
internet access.
The interaction between the operator and the spinning mule happens through an
interface with a guided menu that enables to command either the right and left side
of the machine by a simple pressure on the touch-screen.
The computerized system controls all the machine functions, including the carriages
movement, the feed carriage speed, the adjustment of yarn feed speed and drafting
percentages, the reverse speed, the spooling speed, the cops formation. The
centralized computer can also store the production information system, alarms data
recording and production setting data modification history.
