SHEARING:

“Shearing” is a cutting process to remove protruding fibers on the surface of fabric.

SHEARING PROCESS STAGES

1.     Brushing of cloth.

2.     Cutting of projecting fibers.

3.     Suction of fiber removed by shearing.

SHEARING MACHINE PARTS & WORKING

1.     Outer casing which cover the machine assembly.

2.     A guide roller which just facilitates the movement of fabric.

3.     Two brushing rollers, first is in opposite to the direction is which the fabric move and second is in the same direction of the fabric. They are use to remove any type of hanging extra materials which can disturbance in process of shearing.

4.     Shearing Machine Parts & their function

5.     An adjustable bed- plate provides a base support for shearing action between the bed plate and cutting plate.

6.     A cutting roller with bladed mounted on it in spiral form which provide extra length of cutting blades from one end to the other  and make sure the contact between the blades and fabric in whole one revolution. Which increase the shearing rate projecting fibers as in a straight blade plate length is less then the spiral blade. Setting of blade require be accurate for a clear cut finish.

7.     A fan after cutting blades used for the removal of the removed projecting fibers.

MACHINE USED FOR SHEARING

            Shearing machine is used for shearing.

AMOUNT OF SHEARING DEPENDS

1.     The amount of projecting fibers.

2.     Length of the projecting fibers.

3.     Speed of bladed roller. (40 meters/min)

4.     Setting between Blade roller to Bed.

5.     Sharpness of the bladed roller
