Negative Tappet Shedding Mechanism.

______________________________________________________
Shedding
A shedding mechanism separates the warp threads into two layers or divisions to form a tunnel known as “shed”. The shed provides room for passage of the shuttle. A shed may be formed by means of tappets, cams, etc.

Types of Tappet Shedding Mechanism
Generally there are two types of shedding :
1. Negative shedding
2. Positive shedding
In plain looms, tappets are used to form sheds.
