Concept:
Sizing (or slashing) is the process of applying a protective adhesive coating to warp yarns.
Step 1: Entry and Application.
The yarn begins at the C (Creel) and passes into the E (Size Box) where the sizing liquor is applied and squeezed into the yarn.
Step 2: Drying and Separation.
The wet yarn is then dried using an A (Drying cylinder). Since the size can make yarns stick together, they must pass through D (Splitting rods) to separate individual ends.
Step 3: Collection.
The separated, dried, and sized yarns are finally wound onto the weaver's beam at the B (Beaming unit).
