           Shawl Weaving Artisan - Winding and Warping

           Yarn winding for warp making process

           Objectives : At the end of this exercise you shall be able to
           •  prepare yarn bobbins for warping
           •  calculate the total number of cones or bobbins required for warping process as per the number of ends
            needed for a fabric.

             Requirements

                                                                •  Yarn samples :wool                 - as reqd.
           PROCEDURE

           TASK 1: Prepare yarn bobbins for warping

           1  Put  the right size bobbin to fit  in creel (140mm   Fig 2
              approx). (Fig 1)
            Fig 1

                                                                4  Avoid  overfilling  of the yarn label  and  arrange
                                                                   bobbins according to the warp sequence or pattern.
                                                                5  After completing  the pre-determined  length  of the
           2  Inspect yarn knots or damage.                        yarn in the package stop the machine and remove
           3  Attach the wool yarn to the bobbin and wind evenly   the bobbin.
              with steady tension. (Fig 2)                      6  Place the new bobbin and follow the winding process.

                                                                7  Observe all bobbins are evenly wound with consistent
                                                                   tension.

           TASK 2: Calculate no. of cones/ bobbins required as per no. of ends

           Formula                                              •  Available  creel  capacity: 300 positions  (For
                                                                   example: creel can hold 300 cones at a time)
           Number   of   cones
                           =  Total   number   of   Ends        Calculation
           Bobbins   required
           (Assuming one end per cone/bobbin  and no multiple   Step 1: Calculate the number of cones/bobbins required
           unwinding from the same cone/bobbin)                  Number   of   cones

           Exercise Example                                         Bobbins      = Total Ends = 1200 cones/bobbins
           Preparing warp for  a fabric with the following      Step 2: If your creel holds only 300 cones at a time:
           specifications:
                                                                Number of creel loading runs required = Total Cones/
           •  Total Ends Required: 1200 ends                    bobbins ÷ Creel Capacity
                                                                = 1200 ÷ 300 = 4 runs
