Rationale:
In Diploma level Engineering education skill development plays a vital role. The skill development can be achieved by on hand experience in various instruments, apparatus and equipment. This is accomplished by doing engineering related experiments in practical classes in various laboratories.
Objectives:
Speed Frame
- To practice the various settings of the Speed frame
- To calculate the Draft, Twist and the machine constants of the Speed frame.
- To calculate the speed, production and efficiency of the Speed frame.
- To calculate the coils per inch and the lay constant of the Speed frame.
- To study the working of the builder mechanisms of the Speed frame and set the same for proper working.
Ring Frame
- To practice the various settings of the Ring frame
- To calculate the Draft, Twist and the machine constants of the Ring frame.
- To calculate the speed, production and efficiency of the Ring frame.
- To study the working of the builder mechanisms of the Ring frame and set the same for proper working.
- To practice spindle and lappet gauging in the Ring frame.
Doubling Frame
- To practice the various settings of the Doubling frame
- To calculate the Twist and the machine constants of the Doubling frame.
- To calculate the speed, production and efficiency of the Doubling frame.
- To study the working of the builder mechanisms of the Doubling frame and set the same for proper working.
- To practice changing the twist direction in the Doubling frame.
- To practice spindle and lappet gauging in the Doubling frame.
Reeling Machine
- To calculate the speed, production and efficiency of the Reeling Machine.
- To study the working of the 7 lea mechanism of the Reeling Machine.
- To study the working of the doffing mechanism of the Reeling Machine.

Specific Instructions To Carry Out In The Practical Class Work As Well As The Board Practical Examinations
The students are instructed
- To do the activities which are pertaining only to the specific experiments they are doing
- To maintain their work place clean and tidy
- To handle the tools and other gauges properly and with due care.
- Not to wander from place to place unnecessarily
- Not to talk with other students unnecessarily
- To get their observation notes signed by the staff in charge immediately on completing the experiment
- To complete their record notes and gets it signed by the staff in charge when they come to the next practical class.
- Not to indulge in any malpractice
Safety Precautions To Be Followed
The students while doing the experiments,
- Should wear safe foot wear, preferably shoes.
- Should keep their shirts tucked in.
- Should do settings on the machines only after the mains supply is switched off.
- Should inform the staff in charge immediately if they find any unsafe condition in the machine.
- Should not wear loose shirts.
- Should not open the doors and covers while the machine is running.
- Should not start running a machine without doing regular safety checks and closing the safety doors.
