Question

In \(\underline{\hspace{2cm}}\) mechanism, the shuttle passes through the shed from one shuttle box to the opposite shuttle box.

• A. Shedding
• B. Picking
• C. Beat up
• D. Let off

Hint:

Remember the three primary weaving motions in order: 1. Shedding: Open the warp. 2. Picking: Insert the weft. 3. Beat-up: Push the weft into place.

Answer 1

The Correct Option is B

Step 1: Understand the primary motions of weaving. There are three primary motions required to interlace warp and weft yarns to form fabric.

Step 2: Define each mechanism.
- Shedding: The process of dividing the warp threads into two layers (an upper and a lower layer) to create a tunnel or passage called the "shed".
- Picking: The process of inserting the weft yarn through the shed. In a shuttle loom, this is done by propelling the shuttle, which carries the weft, from one side of the loom to the other.
- Beat up: The action of pushing the newly inserted weft pick firmly into the "fell" of the cloth (the point where the fabric is already formed). This is done by the reed.
- Let off: This is a secondary motion that involves releasing new warp yarn from the weaver's beam to allow for fabric formation to continue.

Step 3: Identify the mechanism described. The action of the "shuttle pass[ing] through the shed from one shuttle box to the opposite" is the definition of picking on a shuttle loom.
