Weaving process/Loom timing
In order to interlace warp and filling yarn to make woven fabric, it is necessary that four basic operations are implemented in sequence and continuously. These include:

1. Shedding
The separation of the warp threads into two (or more) sheets according to a pattern to allow for weft insertion (the most important weaving operation)

2. Weft insertion (picking)
To place weft yarn in the shed (the complementing weaving operation)

3. Beating-up
Forcing the inserted pick into the shed up to the fell of the cloth
4. Letting off and taking up
Warp let-off: supplying more warp yarn by unwinding of the warp beam as the cloth is woven.

Fabric take-up: draw forward the woven fabric as a new pick is inserted.
