Warp knitting

At Groz-Beckert all components of a warp knitting system are coordinated with one another. The perfect interaction of spring beard needles and system parts guarantees a uniform and flawless warp knitting process. Machine builders around the world rely on Groz-Beckert as a development partner and quality supplier. We steadily develop our product range on the basis of this know-how.

In warp knitting machines, all needles move together on a needle bar. Warp fabrics can be identified by their primarily vertical straight grain, whereby thread is usually fed from warp beams and/or bobbin creels. The broad scope of application generates a large number of very different machines, markedly different in their arrangement and number of warp elements needed, as well as in their thread-feeding systems.

Typical application fields are the production of outerwear, underwear, sportswear and shoe uppers.

Shoe and clothing textiles

Typical application fields are the production of decorative textiles and bedding.

Home textiles

Typical application fields are the production of agricultural and packaging textiles, mobile textiles, industry textiles, geotextiles, medical textiles, construction textiles, protective textiles and sports equipment.

Technical textiles

Composites are fiber-reinforced materials made of two or more bonded materials or plys. These applications involve bi- or multi-axle cores which are manufactured on weft-insertion machines and can be combined with other materials such as glass chips and non-wovens. By using high-performing fiber such as glass and carbon yarns, composites can replace classic materials such as steel in various applications. They feature lighter weight at higher rigidity and lower expansion under temperature fluctuations.

Composites for fans and auto bodys

Different types of elastic and unelastic lace is employed in the manufacture of outer- and underwear for women. It is produced either as broad cloth or in separable chain form on multi-bar Raschel machines and galloon crocheting machines. Different lace for the finest lingerie or for coarse crochet can be manufactured on warp-knitting machines. Depending on machine setup, the number of guide bars and the use of a jacquard sample arrangement, a wide variety of samples can be produced which are marketed under such names as "Jacquardtronic" and "Textronic". Many samples look deceptively like real hand or Leavers lace, at significantly higher production speeds.

Compound needles

The product range encompasses compound needles for technical textiles, home textiles and textiles for the shoe and clothing industry. Gauges range from E1 to E50 for almost all warp and galloon crocheting machines.

Latch needles

Single and double needle bar Raschel machines still use many latch needles.

Patent needles

Groz-Beckert has been producing Patent needles for a long time. They serve a small application field and are usually used in the production of niche items.

Spring beard needles

Nowadays, spring beard needles are primarily still employed in old warp knitting machines and as threading needles.

Closers

In order to secure the loop-formation function at today's speeds and to minimize heat in the needle slot, the closer and the compound needle must work in total harmony.

Guide needles

Guide needles from Groz-Beckert feature high accuracy and high wear protection, regardless of machine gauge.

Flat parts

There is a wide variety of flat parts depending on machine type and gauge. These include, in particular, holding down / knockover sinkers, stitch comb sinkers, knock-over bits and pile sinkers.

Guide needle modules

Guide needle modules are the most common modules in the warp knitting industry.

Sinker modules

The variety of sinker modules results from the many different requirements of the various machine types.

Closer modules

Uniformity in loop formation is challenging for closer modules, which must be precisely adjusted on the bar and moved in the needle slot.
