Loom Drive | Function of Loom Drive | Methods of Loom Drive | Individual Drive System | Group Drive System

Loom Driving Function:
It may be divided into four steps which are as follows: 
Loom Drive
1. The rest position of the machine
2. Starting a weaving machine with friction clutch.
3. Normal running of loom.
4. Stopping the weaving machine.

Methods of Drive:
Looms are driven by one of the following two methods:

1. Individual drive
2. Group drive

Individual Drive System:
In this modern system each loom has its own electric motor and a starter. The motor may drive the loom through a belt or gears. Individual drive is used for automatic looms and unconventional looms. Now a day it is also used for non-automatic loom.

Advantages of Individual drive system:
1. There is considerably economy of power as power losses are less.
2. In case of motor failure, only a particular loom remains idle and this does not affect the working of other machines.
3. It gives a clear view of the shed and the working hazard being reduced. Cleanliness and lighting are also improved because of elimination of overhead shafts and long belts.
4. Lay out of looms is very easy.
5. Replacement of belt takes very little time as direct drive motor employs grooved pulleys and V belts.

Disadvantages of Individual drive system:
1. High initial cost
2. High maintenance cost

Group Drive System :
In this system, very powerful motor drives an overhead shaft (sometimes underground shaft) called main shaft, that runs form one end to other end of the loom shed. This main shaft drives the pulleys on the crank shaft of a loom through flat belts. For starting and stopping the loom, fast and loose pulleys are provided on the crankshaft.

Advantages of group drive system:
  • Economical with respect to fixed charges and maintenance.
  • Initial cost is very low.
Disadvantages of group drive system:
Group drive is obsolete now a day because of the following disadvantages:

1. Shafts, pulleys, belts etc absorb greater power and efficiently is considerably low.
2. In case of motor failure all machines become idle.
3. It gives a clumsy appearance and there are greater chances of accidents. Cleanliness and lighting are badly affected by the presence of overhead shafts and main belts.
4. Gives greater power cost for driving, because of power losses.
5. Lay out is difficult.
