Flat knitting

Flat knitting machines work with up to four needle carriers which are opposite one another like a V-shaped roof. As in circular knitting machines, the movement of the needles is controlled by cams. These cams are attached to the carriage of the flat knitting machine. The carriage performs a horizontal movement over the needle carriers.

Typical application examples are the manufacture of outerwear, such as pullovers, jackets, vests and accessories like collars, cuffs, caps and also 3D molded parts for technical applications like upholstery.

Technical textiles possess special properties. Their areas of application are virtually unlimited, where they encounter people on a daily basis – whether on the sports field, in the car or at work. Technical textiles can be manufactured with very different technologies. Typical flat knit technical fabrics include bandages and compression hosiery. The opportunity to create a shape and produce certain functions in a targeted way in the knitting process makes flat knitting technology especially interesting for these application fields.

Technical textiles

Special knitting techniques allow knit shoe uppers to be produced from a single piece. They do away with the joining of parts, around 30 pieces in a conventional sport shoe. But the manufacture of knitted shoe uppers requires special properties of the knitting machine needles used. Enhanced hook stability and reliable latch operation when opening and closing are extremely important. Knit shoes feature a high level of comfort. They are lightweight and fit the foot like a sock.

Knitted shoes

As ever, production of clothing textiles is the largest application field for flat knitting technology. In the fashion industry, primarily flat knitting machines are used to produce pullovers, collars and gloves. Flat knitting technology is particularly suited here, since all parts can be knit into a specific shape. This means that the parts will not subsequently need to be cut to size, saving costs, time and other production factors.

Custom-tailored solutions

Wire butt needle

In addition to state-of-the-art flat knitting needles for latest-generation machines, Groz-Beckert continues to manufacture wire butt needles of the kind found in old, hand-operated flat knitting machines.

Links needle

Links needles, also called double-headed needles, are equipped with two loop-forming parts, located at the ends of the needle.

Latch needle without transfer function

Latch needles without transfer function are mainly employed in collar and glove knitting machines. Since very rigid collars are knit, the needle must be very stable.

Latch needle with transfer function

For complex knitted fabrics it is necessary to transfer loops from one needle to another needle on the opposite side. This requires a transfer function.

Spring-loaded latch needle with transfer function

Many errors crop up in knitting when inserting yarn and casting off loops. Precisely in these processes, spring-loaded latch needles provide additional security.

Compound needle with transfer function

Latch needles only have limited suitability for some special applications. Compound needles come to the rescue here. They involve a very sophisticated technology.

Coupling parts

Coupling parts are used as connecting elements between needles and selecting jack.

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.

Selecting jack

Secured spring force, constant reaction time and good rounding ensure a reliable functioning of the selecting elements. This prevents selection errors, thus increasing customer profits.

Press jack

During the loop formation process, press jacks ensure that the knitted fabric does not ride up.
