Limitations to the weft insertion rate of a plain loom is imposed by,Question 3Answera.The width of the loomb.The loom eccentricityc.The picking and checking systemd.The mass of the sley
Solution
The limitations to the weft insertion rate of a plain loom are imposed by several factors:
a. The width of the loom: The wider the loom, the longer it takes for the shuttle to travel across, thus limiting the speed at which the weft can be inserted.
b. The loom eccentricity: The eccentricity of the loom, or the deviation from a perfect circular motion of the shuttle, can also limit the weft insertion rate. If the motion is not smooth, it can cause delays or errors in the insertion of the weft.
c. The picking and checking system: The efficiency of the picking (the process of throwing the shuttle across the loom) and checking (the process of stopping the shuttle at the correct position) system can greatly affect the weft insertion rate. If these systems are not working optimally, it can slow down the entire weaving process.
d. The mass of the sley: The sley is the part of the loom that beats up the weft, packing it into place in the woven fabric. The heavier the sley, the slower it moves, which can limit the speed of weft insertion.
