b. Picking Motion: The actual passing of the shuttle through the shed of the loom. The shuttle passes over the lowered ends of the shed and under its raised ends. The shed permits the shuttle to pass through it and thereby makes it possible for the shuttle to deposit the pick or filling yarn.

c. Beating-Up: The actual beating into place of the loose pick that was placed In the shed of the loom in the picking motion. Beating-up makes each and every deposited yarn a component part of the woven cloth, The reed beats this pick into place with each consecutive turn of the crankshaft.
