Legwear / small diameter circular knitting

The socks sector encompasses a wide range of machines: single and double cylinder machines as well as single cylinder machines with dial. Transfer techniques used on single cylinder machines with dial additionally allow to produce a variety of patterns. These machines are offered with typical diameters from 3.5 to 6 inches, whereby depending on the gauge, needles with a thickness from 0.26 mm to 1.55 mm are employed. The machines are working with one to four feeds, depending on pattern options.

As opposed to large diameter circular knitting machines, sock machines do not knit continuous tubular fabric, but rather individual socks. The high level of technology these machines boast is on display in the capability, among others, to automatically close toes, thus manufacturing a ready-made article in one operation.

Seamless hosiery machines – in contrast to large diameter circular knitting machines – manufacture individual items that are not pulled off as tubular fabric, but rather ejected individually.

Typical application fields are the manufacture of men's, ladies' and children's socks, sport and functional socks, as well as medical socks.


Contrary to flat knitted compression socks, circular knit socks do not have a seam and can thus be manufactured more quickly and in larger quantities. These socks are applied primarily to prevent thrombosis, for instance in hospitals and airplanes, and to treat varicose veins. But compression socks are also used in sports and hiking for better blood flow.

Medical socks

Seamless hosiery is worn for both pragmatic as well as fashion purposes. It warms the legs, and in cold weather seamless socks or pantyhose made of two seamless socks protect the skin from drying. Seamless socks are also used to flatter the figure and conceal skin problems.

Custom-tailored solutions

Single cylinder sock needle

Using Groz-Beckert sock needles guarantees a particularly trouble-free knitting process.

Single cylinder sock needle with break-off notch

Butt breakage due to mechanical overload cannot always be prevented. To minimize the effects, and in agreement with the machine builder, certain hosiery needles are equipped with a predetermined breaking groove.

Single cylinder sock needle with transfer function

The transfer function of these needles helps to manufacture high quality openwork patterns or ribbed patterns on single cylinder machines.

Single cylinder sock needle with transfer wing

With the transfer wing, high quality openwork patterns, also called ajour patterns, can be manufactured on single cylinder machines.

Single cylinder hosiery dial needle

Single cylinder hosiery dial needles are relatively short in their overall length. They make it possible to produce real ribbed hosiery. They come with and without transfer function, depending on application.

Links needle

Links needles, also called double-headed needles, are equipped with two loop-forming parts located at the ends of the needle. They are used in double cylinder machines, for instance for classy ribbed men's socks.

Seamless needle

Seamless needles are the thinnest needles available for legwear. They are used to manufacture high quality women's stockings with the smallest loops.


Groz-Beckert system parts ensure long-term uniformity and flawless fabric. Short setting periods and reduced downtime provide for high productivity.

System parts for toe closing system

Toe closing systems in sock machines ensure that the sock emerges finished from the machine, thus making manual closing of the sock superfluous.

Transfer parts

The transfer parts in a sock machine are used to manufacture the top of the sock.

Intermediate jack

The intermediate jack is used as connecting piece between needle and selecting jack. It ensures that a specified needle is securely positioned and performs the right knitting function.
