Difference between, Tappet shedding, dobby shedding and jacquard shedding mechanism:-

Difference between, Tappet shedding, dobby shedding and jacquard shedding mechanism:-

As given below there are many differences that can be observed in all three shedding mechanism. They can be described as,

1. IN TAPPET SHEDDING:-

1) A simple design can be weaved.

2) Maximum 14 heald shafts can be used to weave a fabric. Theoretically it can control 6 - 10 heald shafts.

3) Speed of loom is very high.

4) Heald shaft motion is driven from the below of the loom.

5) For different design different tappets are fitted to the bottom shaft.

6) Fabric cost is low.

7) Production is more than the dobby loom.

2) In Dobby shedding:-

1) Medium design i.e.complex structure can be weaved.

2) Theoretically it can control maximum 48 ,but practically for wool number of heald shafts 36 and for cotton 24 heald shafts is able to use.

3) Loom speed is high.

4) The motion for shedding is given from above of the loom and in some loom from side of the loom.

5) For different designs, different design pegging legs are placed on cylinder.

6) It is expensive in costing.

7) Production is less.

3) In Jacquard shedding:

1. It is used to produce elaborate design i.e. very complex structure.

2) Theoretically it can control any number of warp threads individually.

3) Speed of the machine is low.

4)  Motion is given from the above of the loom.

5) For different designs, different punched cards are placed on cylinder.

6) It is highly expensive.

7) It’s production is less.
