[Problems to be solved by the device]

 However, in the knitting product pulling device of the circular knitting machine described above, when the fiber material of the knitting product W is a light and thin fiber material such as nylon, the knitting product smoothly descends downward, for example, like tights. The weight of the fabric is heavy in the case of fiber products that use such middle gauge (medium gauge) and low gauge (coarse gauge) yarns. Since the knitted product W is twisted into a spiral shape because the knitted product W is twisted into a spiral shape without being adsorbed to the wall surface, it not only impairs the quality of the knitted product W, but also twists the knitted product W after it is taken out of the machine. There is a problem that it has to be fixed, which consumes time and labor and reduces production efficiency.

In order to solve the above-mentioned problems, the present invention provides a knitted product of a heavy body as a net pipe even if the weight of a fabric using a middle gauge such as tights or a thread of low gauge becomes heavy. It is an object of the present invention to provide a knitting product pulling device that improves the quality and production efficiency of knitted products by preventing them from rotating and twisting together.
