PREFACE


2/11

Laboratory manual is prepared as a part of progressive steps taken towards

education to B.Tech textile technology students. It is intended to give guidelines

to undergraduate students for their practical work in weaving lab.

The manual is developed after deep deliberations among experienced faculty

members of the department. It will definitely save time for students and facultymembers who handle the classes. Since it is developed purely from the practical

point of view important is not paid to theoretical expiations.

This is the first edition of the manual prepared for this laboratory. There is ample

scope for the further improvement. The authors request the users to come out

with suggestions for further improvement of the manual.

INSTRUCTION TO STUDENTS

1. Students must operate weaving machines only by trained personnel.


3/11

2. Under no circumstances may affixed warming plates and operating

instructions for the machines be removed.

3. Do not touch moving parts and the areas adjacent to moving parts.

4. Do not play with control buttons, or rest fingers upon them.

5. The following articles of clothing must be avoided

a. Loose garments

b. Long sleeves with no heel covering

c. Open shoes with on heel covering

d. Work coat with buttons at the front

e. No scissors or tools must be carried into the open brest pocket,

because they could fall out.

6. Students are advised to carry out practical classes for three hours.

7. Students should bring the manuals and observations note book for every

practical class.
