The Story of Sakichi Toyoda
Sakichi Toyoda, the founder of Toyota Industries Corporation, possessed a strong ambition to contribute to society from his days as a youth. He had devoted his 63-year-long life to invention.
The fabric usually used in the clothes we wear is produced through two processes: the “spinning process,” where raw cotton is turned into thread, and the “weaving process,” where the thread is woven into fabric. Here we will explain each process in detail using some illustrations.
In weaving, the warp thread and weft yarn are crossed over one another in a set method in order to weave the required type of fabric. A machine designed to accomplish this task is called a loom. First, the warp thread and weft yarn are prepared so that they can be set into the loom.
Prepared beams are set on a looming frame to weave a textile in the following five motions:
1. Shedding: two groups of warps are opened to let the weft pass through.
2. Picking: The weft is inserted between two groups of warps.
3. Beat-up: Pushing the newly inserted yarn back into the fell using reed.
4. Let-off: The warp yarns are unwound from the warp beam.
5. Take-up: The woven fabric is wound on the cloth beam.
