Circular loom Weaving Ring ID Calculation

ALL LOOM FORMULA

 

Internal Diameter of the circular weaving loom is an important factor to produce the required width of the fabric. Hence correct Weaving Ring ID Calculation is very important prior to starting fabric production on the circular looms. Therefore, Wrong diameter calculation result incorrect fabric width, that may lead to serious quality issues if not tackled properly. We should also consider the ring diameter aligned with the Denier because higher and lower deniers impacts differently. There is a minor variation in the ring size if the denier is lower, medium or higher. If the denier is low then the ring ID will be slightly bigger however the ID will be slightly lower if we need to run a higher denier.

 

A simple method for Weaving Ring ID Calculation

Below is the step by step guide and formula to calculate the Internal Diameter of the Ring.

 


Example 1

Let’s assume that we require 600mm (60cm) lay flat fabric. Hence we know that the fabric is tubular and has two sides so the total fabric width is;

Open Fabric Width = Lay flat width (mm) X 2 Open Fabric Width = 600 X 2 = 1200mm

Hence, The formula to calculate Ring ID is;

Ring ID = Fabric Width ÷ π

Therefore, the ring ID to produce 600mm circular fabric will be;

Ring ID = 1200 ÷ 3.1415 = 381.98mm ≈ 382mm

Hence, the final Ring ID is 382mm

 

Example 2

If the required Tubular Fabric Width is 450mm (45cm) then the Weaving Ring ID Calculation will be;

Tubular Fabric Width = 450 mm

Open Fabric Width = 450 X 2 = 900mm

 Ring ID = 900÷π = 900÷3.1415 = 286.487mm ≈286.5mm

Therefore, the Final Ring ID is 286.5mm

 

Important Notes

In addition to the above;

 

For Low Deniers

If we are running low deniers in the loom then 5mm shall be added to the final Ring ID. For instance, the ring ID from Example 1 for low denier shall be;

Ring ID = 382mm + 5mm = 387mm

Similarly, The Ring ID from Example 2 shall be;

Ring ID = 286.5mm + 5mm = 291.5mm

 

For Normal Deniers

There is no effect in the Ring ID for normal deniers therefore the Ring ID will remain the same.

 

For High Deniers

In contrast, for high deniers tape, we will reduce the final Ring ID by 5mm, for instance, in Example 1 for the high denier the ID shall be;

Ring ID = 382mm – 5mm = 377mm

Hence, the ring ID from Example 2 Shall be;

Ring ID = 286.5mm – 5mm = 281.5mm
