DRAWING-IN PROCESS:-(A weaving process)

DRAWING-IN PROCESS (A weaving process ):-

The drawing in process comes just after the preparation of weaver's beam. The weaver's beam is obtained from sectional warping or sizing or Direct warping . The drawing-in process mainly consist of two process. The first process is called "drawing" and the second process is called "denting" . It is mostly performed manually but in large scale textile industries, automatic drawing-in machine are used , where more productivity is required. When the drop wire with closed D are used , the ends are drawn through the D of a drop wire before the heald eyes. The drawing-in process for the execution of a new fabric design is repeated regularly, the warp tying (knotting) process is applied to change a weaver's beam. The tying process is done manually or with the help of knotting machine.

DRAFTING:-

A process of passing the ends through the eye of heald wire or harness according to draft(sequence of drafting end) is called "Drafting ". When the drafting is performed manually, to do this job. The person who draws the ends through heald wire with the help of a drawing hook is called "Drawer"  and the person who gives the ends for drawing from the back side is called "reacher".

Denting:-

When the drafting of the ends is completed, these ends are passed through the dents of the reed. We can say that "denting is the process of passing the ends through the dents of reed according to the denting order of the fabric to be woven".

It can be performed by a single person or two person . In this case of two persons , one person select the ends  and presents them to the other person who passed the ends through the dents of  the reed. 

TYING( KNOTTING) ORBPIECING:-

When the fabric design is repeated on the same loom after the weaver's beam exhaustion , there is no need to perform the drawing-in process on that loom. The tying process is used to replace the exhausted weaver's beam with a new weaver's beam. Tying or knotting is the process of joining the ends of an exhausted weaver's beam with ends of the new weaver's beam . When it is performed manually, it is called "piecing". When it is performed mechnically is called "knotting " 

METHOD OF DRAFTING :- 

There are two methods of drafting which are given below; 

1) Manual Drafting Method.

2) Automatic Drafting Method.

(1) Manual Drafting or Hand Drafting:-

This method is performed manually. It is also too time consuming process in the drawing-in process . Highly skilled persons are needed to perform this task. The required number of Heald wires are inserted into each heald shaft according to the total number of ends present in the weaver's beam.

These heald shaft are hung on the stand

 Now weaver's beam put just behind the stand. Each end of the barrel of the weaver's beam rests on the two bearing fitted on the small iron stand . These bearing helps to rotates the weaver's beam in any direction . Now the warp sheet passes over the aluminium pipe fitted across the full width of the drawing stand. If the beam is prepared on the sectional warping machine, it had ends separation lease. The reecher clears the end with the help of a dressing brush. If sized weaver's beam is used , then needed to fix the ends on ther place with the help of half reed of suitable count . Before hanging the warp on the aluminium rod (pipe) one or two layers of warp sheet are unwound.Now the ends of the warp sheet are fixed with gum tape. The half meter length of warp sheet is unwind again and another gum tapes put on the warp sheet. Now half reed is inserted between the two gum tape fixed earlier on the warp sheet. This half reed is tied with the drawing stand. This half reed prevents changing the position end crossing the sheet . Now reacher selects the end according to lease or half reed and present it in front of the eye of the heald wire selected by the drawer. The drawer inserts the drawing hook into the eye of the heald wire and the reacher put the selected ends in the hook. When the drawer pulls the hook the ends also comes with a drawing hook, thus the ends is drawn through the eye of the heald wire. This action repeated again and again till the completion of the drafting full sheet of warp of weaver's beam . When the drafting is completed, the end is passed through dents of reed. Where one person does this process , he firstly selects the ends , then inserts the denting stripe into the dent, then put the selected end into the slit of denting stripe. Now he grips the stripes with the help of his left hand under the reed and pulls the stripe. Thus the end is passed through the dent of reed. This action repeated till the completion of dent of the full warp beam ends.
