3. ABOUT WINDING MACHINE
WHAT IS WINDING?
 Definition: The process of transferring yarn from small
packages like hank, bobbing etc to a large package such as cones,
pirns, cheese etc, containing considerable length of yarn is called
winding.
 Example: From hanks to bobbins, bobbins to cone, cone to pirn etc.

4. Objectives :
 To transfer yarn from one package to another
suitable package, this can be conveniently used
for weaving purpose.
 To remove yarn faults like hairiness, neps,

9. Two flanged contain both side of the package & yarns
are wound parallel. In this process there is no
necessity of traversing.
Parallel Winding :

10. Advantages :
 Many yarns can be wound at a time.
 No need of traversing mechanism.
 Side withdrawal is possible.
 The density of yarn is more.
 No change of number of turns per
inch.
Disadvantages:
 Two sides of the package need
flanged.
 For yarn unwinding, need
separate mechanism.
 Can not be over withdrawal.

11. Near parallel winding :
This package contains only one yarn & yarn is
wound near parallel. Layers contain continuously
inner side of the package.

12. Advantages & Disadvantages of Near Parallel
Wound Package
Advantages:
 No need of flanged
 Can be side withdrawal.
 No change of number of yarn turns
per inch during winding.
Disadvantages:
 Need of traversing mechanism.
 Can not be side withdrawal.

13. Cross wound package:
This is wound crossly by
single yarn.
Advantages: Disadvantages:
 No need of flange . Can not be
side with drawl.
 Can be over withdrawal.
 Yarn package is stable.
 Number of yarn turns per inch is
changed in this method.
 Quality of yarn is less.
 Need of traversing mechanism.

14. Various types of tension device
(According to working principle) :
It is a simple form of yarn tensioner. It works by
deflecting the yarn around the fixed posts. This
induces a capstan effect on yarn.
Capstan Tensioner:
Output tension= input tension X eµθ
Or, T2=T1 X eµθ
Where,
T1= input tension,
T2= output tension,
μ= coefficient of friction between yarn & post.
θ= Angle of lap (in radian) = θ1+θ2+θ3
e= 2.718
DHAKA UNIVERSITY OF ENGINEERING & TECHNOLOGY,
GAZIPUR07-Jan-20 14

15. Additive Tensioner:
In this device a dead load or spring is used to
give a fixed increment of tension. The yarn is
passed through middle of the two surfaces in
contact & the force is applied above to give
suitable tension to the yarn.
Here, T2=T1 + 2μF Where,
T1= input tension
T2= output tension
μ= coefficient of friction between yarn & post
F= applied force.

16. Combined Tensioner :
It is the combined system of capstan &
additive tensioner. The device permits the
tension level to be raised to any desired
extent, but it does not permit a reduction
in tension.
Here, T2=T1eµθ+ T1 + 2μF Where,
T1= input tension,
T2= output tension,
μ= coefficient of friction between yarn & post.
θ= Angle of lap (in radian) = θ1+θ2+θ3
e= 2.718

17. Automatic Tensioner :
This is special type of
tesioner. In this device
the yarn tension is
controlled automatically.
DHAKA UNIVERSITY OF ENGINEERING & TECHNOLOGY,
GAZIPUR07-Jan-20 17

18. Factor influences for selection of tensioner :
 The device must be reliable to control uniform tension.
 It must be easily threaded.
It must not introduce differences in twist.
 It must not be affected by the presence of oil & dirt.
 It must be easily adjustable.
It must be capable of easy cleaning.
 The operating surfaces must be smooth.
 It must be cheap.
 It must be simple in design & operation.
 It must not damage for yarn.

19. Depending On the type of the working
member acting on the yarn :
 Ball type
 Washer type
 Disc type
 Roller type
 Comb type
 Two zone type

20. Types of Yarn guides:
Type- A : Yarn end is required for threading.
 Takes extra time for threading.
 Yarn passed through the guide hole.
 Occur more friction with the yarn.
 No possibility to run out the yarn.

21. Type- B: Yarn end is not required for threading
 Treading is very easy
 Operations time less
 Low cost
 Possibility to run out the yarn

22. Yarn withdrawal or Unwinding:
Unwinding process of yarn from a package is called
withdrawal of yarn.
There are two types of withdrawal:
1. Sideway withdrawal.
2. Over end withdrawal.
DHAKA UNIVERSITY OF ENGINEERING & TECHNOLOGY,
GAZIPUR07-Jan-20 22

23. Side way withdrawal:
 Package rotates
 Occur for flanged bobbin
 Yarn twist become unchanged
 No balloon formation
 Slow process
Over end withdrawal:
 Stationary package
 No flange bobbin is used
 Yarn twist may changed
 Balloon formed during withdrawal
 High speed process

24. Ballooning: The appearance of the
curved paths of running yarns during
spinning, doubling or winding on or while
they are being withdrawal over-end from
packages under appropriate yarn winding
conditions e.g.; when yarn is withdrawal
through a guide ( often called balloon eye)
placed above and in the line with the axis of
the package at an adequate distance from it.
The yarn (travelling at sufficient yarn winding
speed) assumes the appearance of a balloon
shape as it is revolves during withdrawal
from a package. This is called ballooning.

25. WINDING EFFICIENCY :
Definition: The ratio of actual production and
calculated production is called winding efficiency.
Winding Efficiency = ×100
Efficiency Loss = ×100
DHAKA UNIVERSITY OF ENGINEERING & TECHNOLOGY,

26. Winding Faults :
 Breakage of yarn
 Soft or Hard package
 Incorrect winging speed
 Twist variation
 Tension variation
 Dirty package
 Oil or grease package
 Hairiness package
 Poor unwinding
 Slack Knot
 Overlapping
