  7. 7. The Spinning cycle Spinning is the process by which wool fiber is turned into yarn.  Blending: the raw material ,fibres staple, has to be opened , cleaned, blended and treated with oils and antistatics.  Carding: fibres have to be well lined up and divided into slivers (soft yarn, without mechanic firmness)  Spinning: Slivers through operation of drafting and twisting , gain mechanical firmness and become yarns more or less fine.  Finishing: obtained yarns can have other structural finishing as for example yarns coupling, or aesthetic finishing such as washing, steaming, dyeing and so on .... These steps can be not necessary.  Packaging: obtained yarns can be packed on paper cones, balls or directly on plastic tubes, as frame output. During spinning, wool fibres are drawn out and twisted together to form yarn. They can be twisted and wound in different ways. There are two main spinning routes for wool: worsted and woollen systems. 7 - Made In Italy Textile Spinning Machinery since 1901
  8. 8. The Spinning methods  Worsted spinning converts “long fiber” length wool top into yarn.  Woolen yarn spinning converts “short fiber” length carded wool into yarn Woolen spinning , in order to obtain resistant and well-blended yarn from sliver, consists of three main steps: - Drafting - Twist insertion - Winding onto the cop There are two major types of woolen spinning machine:  self-acting mule spinning  ring spinning. The main difference between them is that these three steps are performed differently by each machine. On the mule they occur in a discontinuous way whereby the drafting and twist insertion occur separately from winding onto the cop. The ring-spinning machine combines them into a continuous sequence. 8 - Made In Italy Textile Spinning Machinery since 1901
  9. 9. Products range and installations Though we manufacture different types of textile machinery for carded fibres spinning, our strategy is mostly based on a specialization : we are one of the few manufacturers in the world able to supply modern advance spinning self acting mules that do represent our main range. Self acting mules Model B4 Model B5 300 installations Model B6 e B7 260 installations  Ring spinning frames 220 installations  Fancy yarn machines 80 installations 9 - Made In Italy Textile Spinning Machinery since 1901
  10. 10. Why the self-acting mule(1) The mule spinning frame guarantees the production of very high-quality woolen 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 low. 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. 10 - Made In Italy Textile Spinning Machinery since 1901
  11. 11. Why the self-acting mule (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 drafts 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. 11 - Made In Italy Textile Spinning Machinery since 1901
  12. 12. Why the self-acting mule (3)  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’s price.  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 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. 12 - Made In Italy Textile Spinning Machinery since 1901
  13. 13. The Green Label - Made In Italy Textile Spinning Machinery since 1901 7
  14. 14. What is the ACIMIT green label? The ACIMIT green label is a document that aims to identify the energy and environmental performances of textile machinery and make them easily recognizable and comprehensible, using a process designated by the manufacturer as an evaluation parameter.  In the absence of an internationally recognized standard for the classification of energy and/or environmental performance levels for textile machinery, Italian machinery manufacturers are promoting an instrument whose goal is to demonstrate some key performance data for their machinery.  Specifically, the quantity of equivalent emissions of carbon dioxide (Carbon Footprint - CFP) produced during the machine's operation, is the parameter that has been chosen to provide an environmental efficiency value to the machinery being labeled.  An international certification organism, RINA (, has validated the green label issuing process and the evaluations it contains. Based on a standardized and certified procedure, RINA verifies (for some manufacturers, drawn from those participating in the project every year and representing about 20% of the joined companies) both the evaluation criteria and operating conditions of the machinery being assessed for the labeling process. - Made In Italy Textile Spinning Machinery since 1901 7

  19. 19. 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 slowly unwounded 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 19 - Made In Italy Textile Spinning Machinery since 1901
  20. 20. 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 cop in the position determined by the faller 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 cop, 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 relative to yarn tensioning on the cop 20 - Made In Italy Textile Spinning Machinery since 1901
  21. 21. 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. 21 - Made In Italy Textile Spinning Machinery since 1901
  22. 22. 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. 22 - Made In Italy Textile Spinning Machinery since 1901
