After being spun on the mule spiders the yarn which is on “cops” is then moved to winding. The winding machine undertakes quality control processes and also winds the yarn from the “cops” onto cones. The cones are what the yarn will be sold on and usually weigh 1kg. We buy yarn in Kgs and the cones arrive ready to be threaded up to our knitting machines.
The winding machine also checks the yarn for any inconsistencies. Sometimes if the yarn is required to be thicker it is then taken to the twisting frame which will twist it to the necessary ply (ply means thickness of yarn). This machine twists together the 1-ply strands from the cones to the desired thickness of yarn onto other tubes to create Double Knitting wool (2 strands), Aran wool (3 strands) or Chunky wool (4 strands).
Below and above is the winding machine. Winding is the process of transferring the yarn from the ‘cops’ (which you might remember from the Spinning blog post) onto cones which are then ready for the stockroom or for sale.
Below: This is the pre-twister where the yarn is assembled onto a bobbin ready for up twisting. (Up twisting is making the yarn 2/fold).
Below: The Up-Twister which is the machine making 2/ply yarn after the pre-twister. The term “Ply” refers to thickness of the yarn.
Below: Empty cones after coming off of the 2 for 1 twisting machine.
