Counter Shaft Arrangement In weaving

Object

• To control a maximum of eight or ten heald shaft in tappet shedding.
• To change the speed of the tappet so can be woven fabric design repeating up to eight or ten pick per repeat.

For a Plain weave structure, normally two tappet are required. they are normally mounted on the bottom shaft. but in case of a twill weave structure in 4 ends and 4 pick repeat so we required 4 tappet. they are mounted on counter shaft.

Counter Shaft Arrangement 

 

 

Along with this the gearing that drive the counter shaft on which shedding tappet are mounted , is also to changed to give the correct speed ratio between the counter shaft and bottom shaft .

changing the tappet & gear wheel require stopping of the weaving machine for longer time, thus losing production.
