           •  fix the pirn on winding spindle
           •  starting and stopping of pirn winding machine.

             Requirements

              Tools/Equipment’s/Instruments                     Materials
             •  Pirn winding machine             - 1 No         •  Cone bobbin                        - 1 No.
             •  Empty Pirn                       - as reqd.

           PROCEDURE

           TASK 1: Fix the cone on pirn winding machine

           1  Turn the machine  powered  off to avoid  accidental   8  Pass the yarn through the machine’s thread guides,
             movement during the process.                          tensioners, and eyelets.

           2  Collect the required cones to be fixed.           9  Then adjust the tension of the yarn.
           3  Inspect the cone holder or spindle for wear, damage,   10 Rotate the  spindle manually to  ensure the  cone
             or misalignment.                                      spins freely without obstruction or misalignment.

           4  Clean  the holder  to remove dust, lint, or old  yarn   11 Ensure  the yarn feeds  smoothly  from the cone
             remnants.                                             without snags or breaks.
           5  Verify  that  the  cone size  matches the  holder or   12 Turn the machine back on and run it at a low speed
             spindle specifications.                               to test the setup.
           6  Place the cone on the holder or spindle securely.  13 Monitor the winding process to ensure the yarn is
                                                                   distributed evenly on the pirn and the cone is stable.
           7  Avoid over tightening, as it can damage the cone or
             holder.                                            14 If any issues persist, remove the cone and repeat
                                                                   the process carefully.

           TASK 2: Fix the pirn on winding spindle

           1  Check the pirn for any damage or defects.         9  Then pass the yarn through the guides, tensioners,
                                                                   and eyelets of the machine.
           2  Ensure the pirn is clean  and free of old yarn or
              residue.                                          10 Secure the yarn to the pirn’s tip using a small knot or
                                                                   wrap it around the pirn tip.
           3  Check the  spindle for  cleanliness and ensure it  is
              free from debris, lint, or worn-out parts.        11 Set the machine speed appropriate for the type of
                                                                   yarn and pirn to avoid uneven winding or damage.
           4  Hold the pirn in alignment with the spindle.
                                                                12 Rotate the spindle manually to ensure the yarn flows
           5  Push the pirn gently but firmly onto the spindle until   smoothly onto the pirn without tangles or resistance.
              it sits securely.
                                                                13  Ensure the yarn is being wound evenly and tightly
           6  Ensure the pirn’s hole fits snugly over the spindle   onto the pirn.
              without excess play.
                                                                14 Check that the pirn remains stable on the spindle.
           7  Rotate the pirn manually to ensure it spins smoothly.
                                                                15 Check the pirn and spindle  during  the winding
           8  Turn the spindle by hand to check for smooth rotation   process to address any issues promptly.
              and ensure there are no obstructions.
