How to Construct a Drafting Plan from a Design

Creating Drafting Plan – Step-by –Step -Procedure

First let us understand the meaning of the ‘straight Draft. Let us draw our full previous design again.

Step 1: Number the columns starting from 1, from the left. The number represents the number of ends in the repeat. It is already done in the design.

Step 2: Find out which ends (colums) are working alike. We find that column 1,5 and 9 are working alike. Thus from the principle of drafting they should be on the same heald shaft.

Similarly sets of ends (2, 6, 10), (3, 7, 11), (4, 8, 12) are working alike, these four all the ends on the set should be on the same heald shaft.

As we have four sets (1, 5, 9), (2, 6, 10), (3, 7, 11), (4, 8, 12), which are working differently, these sets should be on different heald shafts. Thus we need in all four heald shafts.

Step 3: Show the heald shaft as rows on the drafting plan and ends as columns.

Now we are ready to make drafting plan. Generally drafting plan is shown above the design.

As there are 4 heald shafts and 12 ends so we need 4 rows and 12 columns. Therefore our drafting plan will look like:

Numbering the heald shaft from bottom to top and placing it on top of the design we have:

Step 4 Marking

As 1st, 5th, 9th ends work alike (all 2 up and 2 down) so they should be drawn through the heald eye of first heald shaft, we indicate this by a cross on the first heald shaft at 1st 5th and 9th columns.

Similarly 2nd, 6th and 10th ends work alika (1 down 1 up 1 down) they should be marked on the second heald shaft in similar way.

In the same way set (3,7,11)th end will go on 3rd heald shaft and the set of ends (4, 8, 12) will go on 4th heald shaft.

Which completes our drafting plan or draft.

This drafting plan or draft is called STRAIGHT because 1st end is drawn through 1st heald shaft, 2nd end working differently in drawn through 2nd heald shaft and so on …
