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.

8







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.

9







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.

Working mule spinning machine B7 DD video

The new self acting mule version "Proxima B7 DD Double Drive" is composed by two sections completely independent.

click here after to launch our You tube video and discover the Bigagli Self acting B7DD mule spinning process

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 counter-faller³ 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



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 counter-faller 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



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.



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.



Mule spinning frame mod. B7 DD : technological innovation

The control system is placed in the central part of the self acting mule. It contains the push buttons to easily operate both sections of the machine and a computerized operator interface. The modern touch-screen monitor allows to interact with the program in a simple way.

.


The accurate tension control system of the spooling and yarn tension fallers guarantees a perfect cop formation, so as to maximise productivity and quality of the subsequent spinning process phases.



Siemens Simotion and Sinamics S120

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.

24






Operator interface

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.

The machine can be fully controlled through intranet network and internet access.
