Introduction: Passing the weft thread, which traverse across the fabric, through the shed is called picking. Picking is a primary motion. These motions must occur in a given sequence, but their precise timing in relation to one another is also of extreme importance on a power loom.
Picking is mainly two kinds. They are
- Hand picking
- Power picking
- Throw shuttle
- Fly shuttle
Power Picking is two kinds. They are
- Conventional
- Modern
Conventional picking is two kinds. They are
- Tappet& cone
- Bowl & shoe
- Cone over picking
- Cone under picking
Bowl & shoe Picking is two kinds. They are
- Side lever
- Side shaft
Modern picking is 4 kinds. They are
- Torsion bar
- Air jet
- Water jet
- Rapier
- To learn about the m/c parts of picking mechanism To get knowledge how will the bottom shaft help in case of picking
- To learn about the effect of subsequent process
Main parts:
- Motor
- M/c wheel
- Picking wheel
- Bowl
- Motor pulley
- Sicle level
- Shuttle
- Picker
- Spring
- Bottom shaft
- Bottom shaft wheel
Working procedure: Motor supplies the power, when motor pulley rotates the m/c pulley is also rotate and crank shaft wheel gets power for rotating. Thus crank shaft wheel teeth are half them bottom shaft wheel. So, crank shaft wheel rotates two times that time bottom shaft wheel rotates one time. Than picking wheel also rotates due to fixed. In the parallel pick method, a curved shoal fixed to the bottom of picking sticks rides on a horizontal plate fixed to the sley sowrd. When bowl rotates and to give pressure on the side shoe and l- level moves to forward direction and weft is occurred.
Comments: By performing this experiment, we have gained vast knowledge about various m/c pars which are help for picking mechanism. It helps us to increase our skill.
