Question

Group I gives a list of loom motions and Group II contains loom systems. Match the motion from Group I with the corresponding system from Group II. 
Group I                       Group II 
P. Shedding           1. Matched cam 
Q. Picking              2. Seven wheel 
R. Beat-up             3. Rapier 
S. Take-up              4. Jacquard 
 

• A. P-1, Q-3, R-4, S-2
• B. P-4, Q-3, R-2, S-1
• C. P-4, Q-3, R-1, S-2
• D. P-3, Q-4, R-1, S-2

Hint:

Each loom motion is associated with specific loom systems designed to perform particular tasks in weaving, such as shedding, picking, beat-up, and take-up.

Answer 1

The Correct Option is C

Loom motions are specific actions that help control the operation of a loom. The correct matching of the motions from Group I with the corresponding loom systems in Group II is as follows:

Step 1: Understanding Shedding and Jacquard
- Shedding is the process where the warp threads are raised or lowered to create the shed through which the weft thread passes. This motion is commonly associated with the Jacquard system, which allows individual control of each warp thread, making it ideal for complex pattern weaving. Therefore, \( P \) matches with 4 (Jacquard).

Step 2: Understanding Picking and Rapier
- Picking refers to the motion that inserts the weft thread into the shed formed during shedding. The Rapier system is a type of picking system where a rapier is used to carry the weft across the shed. Therefore, \( Q \) matches with 3 (Rapier).

Step 3: Understanding Beat-up and Matched Cam
- Beat-up is the process of pushing the inserted weft thread into place by the reed. This is typically done by a Matched cam system, which provides a synchronized motion to beat the weft into the fabric. Therefore, \( R \) matches with 1 (Matched cam).

Step 4: Understanding Take-up and Seven Wheel
- Take-up refers to the motion that collects the woven fabric on the beam after it has been formed. The Seven wheel system is commonly used for this function, providing controlled winding of the fabric onto the beam. Therefore, \( S \) matches with 2 (Seven wheel).

Final Answer: \[ \boxed{\text{(C) P-4, Q-3, R-1, S-2}} \]
