What is the difference between single cylinder and double cylinder socks making machine?
Single cylinder socks have a protruding seam line at the cuff, while double cylinder cuffs are the same on both sides. The seams are relatively flat and not protruding, making them more comfortable to wear.
A single cylinder socks making machine has only one cylinder, while a double cylinder sock machine has two cylinders. The difference between the products produced by the two machines is that the single cylinder cuff has a double layer and is used for weaving plain weave and terry. The double cylinder sock cuff is single-layered, and the double cylinder is used to weave concave-convex patterns.
Turn the sock over and look at the sock tube. If it is the same as the front of the sock, it is a double cylinder sock. If it is different and there is a knot line, it is a single cylinder sock.
