Worked yarns are produced by several methods depending on the type of wool being processed.  

‘’This film deals with the longer stapled Merino wools.  For this type of material combing is carried out on a Noble Comb and drawing is effected by the Bradford Open Drawing System.  The West Riding of Yorkshire is famous for the processing of wool.”
 
Men unpack and sort the wool on benches in the sorting room located on the top floor of the mill.  Having been sorted into qualities, the wool is inspected and passed to the floor below for blending.  Here, the when the wool arrives, it is stacked high on trolleys before being unloaded.  Wool of the same quality but of different types is blended together. 

The wool is stacked high along a long wall where it is inspected.  Next, the blended wool is cleaned, removing any dirt, before moving onto the scouring process.  

It is loaded onto a conveyer belt, and the greasy wool at the end goes for scouring where it is mixed with liquid in the first bowl.  The scouring solution is heated to 120 degrees Fahrenheit.  At the end of each bowl the wool is fed through heavily weighted rollers.  The dirty liquid is squeezed out, and the wool enters a second, third, fourth and fifth bowl before going through a hot dryer.  

It is then conveyed by suction into the Carding room.  Here the fibres are disentangled by wire-covered rollers and a considerable amount of vegetable matter is removed.  Carded fibres leave in the form of slivers which go through a backwash process for more scouring and drying over hot rollers.  Oil is added to lubricate the fibres.  

Slivers are gilled by steel pins, called fallers, and then gilled again ready for combing.  The slivers are then wound onto balls on the comb-baller, or Punch.  

The wool then passes through the Noble Comb where it is mixed, straightened and separated into combed wool, Sliver Top and Noil.  

The Top Sliver goes to Finisher Gill Boxes and is inspected, and then on to the Bradford Open Drawing Process.  The gilled slivers then go next to the Two-Spindle Gill Box, and then on to the Drawing Box.  It is then spun to make different types of yarns. 

When more than two yarns are to be twisted together the Universal Twisting frame is used.  At the end yarns are shown on different carriers:  spools, paper tubes, hanks, cheeses, cones, and warp beams.  

The film finishes stating that 300 million pounds of tops are processed annually.
