What is Beating in Weaving?

Question: What is beating in the fabric weaving process? 

Beating is the third and last primary motion in the weaving operation. Beat-up encompasses a variety of loom components, primarily race board, and sley. The lower portion of the warp yarns is between the race board and the shuttle. A sley is created by assembling the race board and reed. With a reed fixed in the sley, the newly inserted weft yarn is pushed against the woven fabric at the "fell of the cloth." The cranks in the crankshaft cause the sley to move abruptly and quickly in the direction towards the fall of the cloth.

Classification of beating

Beating can be classified into the following three types. 

1. Number of beat-up:

a. Single beat-up - A reed pushes the newly inserted pick in a single beat-up mechanism. Single beat-up is utilized to produce the majority of fabrics that are not particularly compact.

b. Double beat-up - Double beat-up is the term used when two beat-ups occur successively inside one crankshaft revolution after inserting a pick. Double beat-up is used to create very compact fabrics, such as canvas, triple, and tents.

2. Beat-up mechanism:

a. Conventional beat-up – Here the beat-up is done by the crank and the crank arm as in old conventional loom.

b. Cam beat-up – Here the beating action is performed by cams as in shuttles loom.

3. According to the movement of the cloth fell:

a. Fixed fell – Where the beat-up is performed on a fixed fell of the cloth.
b. Moving fell – Where the beat-up is performed on a movable fell.
