The document defines and describes the key parts of a tappet loom. A tappet loom uses tappets, which are levers or projections moved by cams, to produce reciprocating motion that allows the loom to weave fabric. The main components of a tappet loom are the warp beam, heddles, shuttle, reed, tappets, and take-up roller. The tappets are connected to treadles and use cam motion to alternately lift the heddles, creating a shed for the shuttle to pass through and weave in the weft thread.

Drawframe is one of the important machines in yarn spinning line. It is prepared for combining and drawing slivers and removing card irregularities of textile fibres.
INTRODUCTION
The ring spinning will continue to be the most widely used form of spinning machine in the near future, because it exhibits significant advantages in comparison with the new spinning processes.
Following are the advantages of ring spinning frame
• It is universally applicable, i.e. any material can be spun to any required count
• It delivers a material with optimum characteristics, especially with regard to structure and strength.
• It is simple and easy to master
• The know-how is well established and accessible for everyone
Drafting is the creation of a drawing or other graphical representation of a building, mechanical device or other structure for the purposes of determining how the device should be created. Drafting is used as a part of the design and fabrication processes. Drafting can be done by hand or using specially designed computer programs and mechanical drawings.
Drafting arrangement is the most important part of the machine. It influences mainly evenness and strength The following points are therefore very important

The weaving process consists of five basic operations, shedding, picking, beating-up, left off and take up. Shedding: Separating the warp yarns into two layers by lifting and lowering the shafts, to form a tunnel known as the 'shed'. ... Beating-up: Pushing the newly inserted weft yarn back into the fell using the reed.

Andreas Schleicher presents at the OECD webinar ‘Digital devices in schools: detrimental distraction or secret to success?’ on 27 May 2024. The presentation was based on findings from PISA 2022 results and the webinar helped launch the PISA in Focus ‘Managing screen time: How to protect and equip students against distraction’ https://www.oecd-ilibrary.org/education/managing-screen-time_7c225af4-en and the OECD Education Policy Perspective ‘Students, digital devices and success’ can be found here - https://oe.cd/il/5yV
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
5. Tappet is a type of cam to which a rotary motion is given for the purpose of producing
reciprocating motion in rods and levers by sliding contact.
Why Called Tappet Loom?
Loom a hand-operated or power-driven apparatus for weaving
fabrics(Woven Fabric)
6. Cam vs Tappet - What's the
difference?
Cam: a rotating or sliding piece (such as an eccentric wheel or a cylinder with an
irregular shape) in a mechanical linkage used especially in transforming rotary
motion into linear motion or vice versa
Tappet. : a lever or projection moved by some other piece (such as a cam) or intended to tap or
touch something else to cause a particular motion.
7. Various Parts of a Tappet Loom
A. weaver’s beam or loom
beam
B. warp threads (ends,
sheet form)
C. back rest or bearer
D. lease rods
E. “shed”
F. healds
G. reed
H. fell of cloth or beat-up
point
J. shuttle
K. breast beam
L. cloth take-up roller
M. tug bar
N. cloth roller
O. tappets
P. tappet treadles, with anti-friction bowls
R. treadle fulcrum
S. roller-top, heald reversing motion
T. rocking rail, or shaft
U. sley sword
V. crank arm
W. sley
X. top shaft
Y. bottom shaft
8. Weavers Beam/Back Beam/Warp
Beam
The warp beam, which holds the lengthwise yarns, is located at the back of the machine and is
controlled so that it releases yarns to the weaving area of the loom as needed.
9. Whip roll/Back rest
This is guide roller which directs the warp threads on their way to the lease rods and heddles.
10. Lease Rod
Another guiding device it is for the warp yarns. These are two sorts of wooden or glass rods
set between the whip rolls and the heddles.
Alternating warp threads can be kept separate by passing over and under these rods.
11. Drop Wire
Parts of a warp stop motion. Warp yarn passed through drop wire called pinning.
No of warp yarn=no of drop wire
14. Shuttle Box
Shuttle box is the housing for the shuttle and is made of wood. It has a picker
and a spindle. It may also accommodate the picker without spindle. The top
and side of the shuttle box unto the sley race are open. The shuttle dwells
inside the box for the intermediate period between two successive picks.
15. Reed
This is inevitably a combination made up of steel wire rods set vertically in a frame. The spaces
between the wires are known as splits or dents and are kept even and parallel. This is the first
function of reed.
Its second function is to feed the filling thread into position. To do this it has to move in a back and
forth motion.
16. Sley
The part of a loom mechanism in which the
reed is fixed and which moves the reed for
ward to beat up the weft.
17. Picker
Picker is a piece made either of synthetic material or leather. Picker may be
placed on a grooves or spindle in the shuttle box. Picker is used to drive the
shuttle from one box to another. While entering the box it also sustains the
force of the shuttle.
18. Buffer
Usually, the buffer has a hollow cylindrical shape formed by convolutely winding a leather sheet.
object of the invention is to provide a buffer which will withstand the impact of
the picker stick without substantial deformation and loss of flexibility.
