Beat Up Mechanism.

Experiment Name: -Study on the construction of beat up mechanism.

Introduction:

The beating-up is the third primary motion of weaving. It consists in driving the last pick of weft to the fell of the cloth. This is accomplished with the help of a reed fixed in the sley. The sley is given a sudden and quick movement towards the fell of the cloth by the cranks in the crankshaft. The sleywood runs from one shuttle box to another, and when at its backward movement, the shuttle travels over its race.

Objects:
1. To know about the construction of the mechanism.
2. To know about the drive of the beating-up mechanism.

3. To identify the different parts of this mechanism.

Main parts:

1. Crankshaft.
2. Crank.
3. Crank arm. 
4. Reed cap. 
5. Reed.
6. Sley race.
7. Sley.

8. Sleysword.

Description:   

                                

The crankshaft gets drive from motor via motor pulley and m/c pulley. The crankshaft has two cranks. These cranks transform the rotary motion into swinging motion. The reed cap is connected by crank arm to crank of the crankshaft. Again the reed is connected between reed cap and sley. There is sleysword under the sley that is bolted to the rocking shaft. There is also shuttle box on the sley. Now the crank gives the swinging motion to the sley by crank arm. When the sley is moving towards the healdshaft at certain position the shuttle passes through warp shed. Again when the sley is coming towards the front rest at last position the reed pushes the last pick to the previous pick of cloth. This is the beating-up motion and the cloth increases in lengthwise in this way.

Conclusion:
To make a woven fabric interlacement of warp and weft yarns is the main condition. That’s why beating-up mechanism is a very essential motion for weaving. Proper setting and adjustment should be taken for this motion. This practical helps me to know about beating-up motion. I think this will help to build my future career.
