Knitted fabrics on large-diameter circular knitting machines are manufactured as endless tubular fabric with a circular array of knitting needles. In double-jersey machines, needles are arranged in both the cylinder and in the dial, while single-jersey machines use knitting-machine needles as well as sinkers. In shirtmaking on bodysize machines, for example, this eliminates lateral seams. This is particularly advantageous for skintight clothing.
Typical application fields in circular knitting include the manufacture of outerwear such as T-shirts, leisure and sportswear, underwear and sleepwear, among them bra fabrics and technical textiles such as smart shirts.
However, knitted fabrics on seamless bodysize machines, in contrast to large diameter circular knitting machines, are manufactured as individual items and not pulled off as tubular fabric, but rather ejected individually. Circular knitting machines with corresponding diameters are used for the different fabric sizes. For this Groz-Beckert provides high performing needles and system parts such as knitting cylinders.
Typical application fields are the manufacture of medical textiles, underwear and outdoor underwear, bodys and swimwear.
:Knitting Machine Needles
Latch needles
Groz-Beckert has the widest range of latch needles and provides service for all applications – and in gauges up to E90.
litespeed® and litespeed® plus
litespeed® needles have been designed for use in circular knitting machines. They lower machine temperature and cut power consumption for noticeable cost reduction.
Vo-LC™ needle
The manufacture of ultra-fine knitted fabric requires high needle precision. Groz-Beckert offers the optimal solution with the impressive features of the Vo-LC™ needle.
G00 Technology
The G00 technology prevents streaks caused by bent-open hooks. This facilitates increased process reliability at maximum productivity, as well as reduced fabric waste.
Steel composite needle
The needle with double low profile provides ideal damping for high-speed use. The cut-outs of the needle are filled with a special plastic to prevent the accumulation of dirt.
Transfer needle
With this special needle technology, loops can be transferred to adjacent or opposite-side needles. This increases the variety of patterns on the machines employed.
Spring-loaded latch needles
The specific build of the needle, which provides for automatic lifting of the needle latch in closing and open position, delivers many benefits to the loop formation process.
:System Parts
Sinkers
Groz-Beckert sinkers ensure a uniform long-term knitting process and flawless fabric. Short setting periods and reduced idle times provide for high productivity.
Holding-down jack
During the loop-formation process, holding-down jacks ensure that the knitted fabric does not ride up, replacing the holding-down function of the sinker.
:Knitting Cylinder
Cylinder
Groz-Beckert cylinders are highly precise, highly wear-resistant and have a long service life. The gauges run from E3–E90 and are supplied for single-jersey and double-jersey machines.
